Economic Inequality in Australia

Economic Inequality in Australia Why has economic inequality increased in Australia since the 1970s? What have been the consequences of this increase in the quality of life in Australia? Since 1970, people have been challenging the issue of â€Å"conventional wisdom† that was connected to the scarcity aspect rather than attaining successful way of managing affluence. There have been various real problems that required to be addressed. Some of these problems were related to wastage of resources, especially on the weapons of war, the lingering poverty and the imbalance of quality among the public provided services and the privately produced goods that can be summed as â€Å"public squalor and private opulence.† After the post-war period, a new world has been delivered, where there have been dominant ideas and concerns over the past on declining significance that is more than inequality (Atkinson, Piketty Saez 2011). There are few things that can be evidenced in the modern social history rather than the interest of declining the inequality as part of the economic issue. There are various reasons to this. Inequality was not getting to it worse, but it is s till profound. Large part of the population had a sense of the economic inequality and security level. The real income level for all the people increased with dramatically while the wealth for those who were at the top stagnated. This situation was well described by certain theory of transformation. The theory indicates that, as the country was more industrialized, the citizens were able to move away from agriculture to industry. This issue caused inequality to rise since some of the people become richer while other remained poorer. Taking full industrialization aspect of the country would have caused mass education, increased wage for the workforce, and increase political powers for the mass populations. These were part of the issues that could have caused an increased level of inequality in the country. The income inequality level in most of the OECD countries has increased in the past 20-30 years among them Australia (Alderson, Beckfield Nielsen 2005) This paper will explore the causes of increased level of inequality in the country while outlining the nature of the economies using both political and historical techniques. The argument will be based on the fact that, the increased inequality level has been due to the deliberate policy, government ideas of shifting the income from wages to profits. As well, there was a shift of income from low to the middle-income earners and to those who earn higher and s queezing the consumption level with an aim of increasing the reward that is available for the investment. Skill Biased Technical Changes This has been one of the factors that have been debated as a cause of distribution of market outcomes. In Australia, the dominant explanation that can be cited for the increased income inequality is the impact created by the skill-biased technical changes that have been fostered by the globalization. Skill-biased technical changes can be set out as the shifts that are experienced in the production technology that do favor all the skilled individuals (such as the more educated, more capable and more experienced) than the unskilled individuals. They are being favored due to the increased relative production capacity hence has a relative demand (Alderson, Beckfield Nielsen 2005). Skill-biased technical changes in the country have been cited as a mean that deliver premium wages to all individual who have certain specified skills and more to the workforce that has higher education level. The first impact of this issue has been due to the globalization, where production of the unskilled i ndividual is considered quite low. In the economy, labor-intensive commodities are being outsourced to the low wage economic groups, hence reducing the prices. As well, the demand for the unskilled labor in the country has been quite low. As well, another cause is associated with the rise of the production system that do rely on the information technology levels, advanced technology. This situation has a directly increased demand for the skilled and educated staffs compared to the less educated. In the manufacturing sectors, there is an evident rise in the relative employment for the high -educated skilled production staffs, who usually receives higher salaries and wages (Bramble Kuhn 2011). Polarization of Income Distribution at the Top There have been various studies undertaken by scholars to investigate on the extent at which the income inequality may be the main product of the relative low income for the poor individuals. As well, the studies have highlighted or consider the aspect of relative higher incomes for the rich people (Bramble Kuhn 2011). According to most studies, it was found that, the rise in inequality level is related to the aspect of polarization rather than the downgrading or upgrading that may lead to hollowing out of the model income part of the society. As well, it was found that, in the societies that experience the large increased level of inequality, upgrading would have to take precedence over the aspect of downgrading causes such as polarization. In other better terms, the wells off individual have the chances of becoming much richer. This has been the pattern that is evidenced by the rapid increase for the top income earners. In Australia, the share of the total income that is taken by the top 10 percent has decreased from 50 per cent in 1929 and in 1932, it decreased to 35 percent but later in 2007, it increased to 50 percent (Bramble Kuhn 2011). Back in year 1970, the decline of inequity was celebrated but one scholar noted that â€Å"it no longer seemed possible for the ownership of tangible assets of the public and the disposal of the income to pass through negligible number of hands. After few years later, this was the situation on distribution of income changes. The situation that was experienced indicated that, almost one percent of the rich population was able to appropriate more than half of the increase in the national income. The remarkable idea was related to the degree of the top 0.1 percent of the income earners that captured the misappropriated share of the overall national income. According to statistics, the Australian growth rate offers no indication of having experience to most of the population (Brandolini Smeeding 2009). Back in year 1975-2006, the country average real income per household in the country grew by 32.2 per cent but taking the top 1 per cent, the growth was by 17.9 per cent. This is a findi ng that has been challenging the primacy of the skilled biased technical changes as part of the increased income inequality in the country. The rise in the top incomes has been greater than the suggestion of the extra productivity levels of the skilled workers. As well, very few of the top income earners have higher education and the skilled non-finance professions (Brandolini Smeeding 2009). Tax and Welfare Regime In Australia, the income inequality level has increased and the rise may significantly be fostered by the inequality in the market incomes. As well, changes in the tax and welfare regimes have in some ways reduced or increased the impact experienced in the market outcomes. There was in an increase in the inequality of the market outcome between 1979 and 2004 caused by the higher tax rates and the increased level of generosity on social assistance and employment assistance. This was taken in the ways of counteracting the effect of increased inequality in market outcomes or the households. In 1990s, the market income inequality grew rapider and, the tax and welfare program failed in reducing the polarization effect. Lowering the personal taxes mainly for the highest incomes reduced the issue of unemployment benefits, and this assisted in accounting for the rise in inequality. Increased social assistance and tax and welfare reforms were the most deliberate policy and decisions that caused the impact of inequality in the country (Card DiNardo 2002). An argument that was raised stated that, if the effect if taxation of the income at the top was frozen, there would be a very big chunk of the increased inequality for the super-rich and the rest part of the population. As well, recognizing the skill-biased technical changes to have a direct impact on the jobs and wages, it was criticized that the fixation of inequality was among the large section of the income distribution pattern. This was an issue that was obscuring the government policy that targeted becoming more generous toward individuals who were at the top (Bramble 2008). There is an extent of strength of the trade union organization that has been crucial when it comes to limiting the income inequality. This argument has been linked with the decline in income inequality in the post-war years that was d ue to the strong trade unions, the progressive tax methods, low level of unemployment and the welfare system. Collective bargaining has been cited to be the cause of reduced the inequality of pay when compared to the competitive nature market. The inequality increase has been due to the result of a decline in the crucial bargaining power in the government expenditures (Bramble 2008). Economic crisis of 1974-1975 actively contributed to the inequality in Australia. This economic crisis erupted after Whitlam Labor government was re-elected in 1974. During this time, the government policies that were in place swung from the Keynesian stimulus of austerity with struggle of a Minister policy. As well, the Australian trade union has won a case on pay rise but the level of inflation was spiral and out of control hence alarming the business. The society polarized sharply. Australia had strong and organized trade unions that laid their attempts of defending the unions and gain wage rise that could have sustained the real values of price, while the government tried to restrain the wages. This plunged the country into severe political crisis, and this caused seven years of a political impasse. The business, government, and the unions were quite mobilizing with attempts to defend their interest. The political impasse ended in year 1983, this was followed by election of new l abor government, and there were results of unprecedented and restructured economy (Borland, Gregory Sheehan 2001) To end the crisis, the new elected government has to propose Prices and Income Accord that was part of agreement set by trade unions and guaranteed an industrial peace and wage restraints in exchange of guarantee and the government way of protecting the real wages and improve the social wage. All business representative were to be consulted and the trade unions movements especially on economic, tax and social issues. After the Labor won the election, the agreements become the structure of the government for the next one decade. There were a closer ways of monitoring the prices and all the workplace and unions that attempted to increase the wages beyond the maximum agreed rate was highly disciplined (Bagguley 1995). Along the wage policies, the government was able to restructure the business taxation policies. The statutory tax rates were reduced in year 1983 to 46 per c ent and in year 1996 to 36 percent. Changes in the rules that were applied in corporate tax caused a great impact on the effective rate and corporate tax decline. Later in year 1986, the fringe benefits tax and the capital gain tax were introduced (Card DiNardo 2002). These were some of the crucial measures that tried to reduce the income inequality level. The personal taxes that were charged in the higher income individual were cut in two crucial ways. As well, the government has to introduce dividend amputation that tried to reduce the income tax on share dividend a significant reform that benefited wealthy individuals. In the history years, business used to pay for company tax, and dividends were paid to shareholders and they were expected to pay tax on them (Alderson, Beckfield Nielsen 2005) Conclusion The society will never be equal, there must be horizon for the disadvantaged, and they are hard to rise. Normal operations of the economy may place great economy power to the hand of business owners especially when it comes to employee’s relation. The government has to take some alternative and facilitate successful and profitable operations for the business that target a protection of a business owner from the employee’s harmful actions. The government has ideas of reducing the inequality with consideration of low unemployment, increased levels of social security, minimum wages and higher marginal tax rates for the income earners.

The Treasure of the City of Ladies by Christine de Pisan Essay

The Treasure of the City of Ladies by Christine de Pisan Christine de Pisan’s book, The Treasure of the City of Ladies, explains in detail the various aspects of women’s lives during the late Medieval and Renaissance culture. She addresses all women of this time from those with power and authority to the poorest peasant women. Christine de Pisan focuses on three main areas of a women’s life during this time period. First she discusses the role of knowledge and education in the lives of the various women. Then she offers her advice to all the different women of varied backgrounds and social standards. She relates how all of these women are in fact connected due to common concerns. Finally, she depicts how men and women interact with one another. By describing the way in which women are treated by the men during this time, she portrays the typical relationship between men and women during Renaissance times. Women were expected to lead a very specific life, focusing on the men of their society. Throughout Christine de Pisan’s book, she refers to the three ladies of Virtue: Reason, Rectitude, and Justice. These ladies are the foundations of her teachings. She uses them to explain the relationship between men and women and how they view one another. The lady Prudence teaches all the women of that society about the â€Å"rules† they should follow in order to be good Renaissance women, specifically in their relations with men. â€Å"Now we would like to advance for their edification seven principal teachings, which according to Prudence are necessary to those who desire to live wisely and wish to have honour† (62). These teachings say that the women should love their husbands; they should live in peace with men. If they f... ...d the chance to lead a respectable life according to the â€Å"rules† of the ladies of Virtue. In the late Medieval and Renaissance time period, women had a strict standard to live up to. They should love their husbands, respect them, and obey their commands. The men in return fulfilled the women’s needs by supplying them with whatever they needed. The men and women lived with a mutual respect between themselves.

Huckleberry Finn by Mark Twain :: essays research papers

It is my opinion that the book The Adventures of Huckleberry Finn By Mark Twain should be taught in schools because this book is very well written and can teach many lessons. I think that the people in today's world, or maybe just the USA, try to be censor and shelter the children. I think that it is wrong to censor things, this book is supposedly wrong because it says the word nigger a lot and has death in it. I think that although the word nigger was used frequently in this book it showed the separation between the slaves and the owners and how Huck overcame this separation and saw through the societies views on niggers . Racism is now a very big issue but when the book was written African Americans didn't have the rights they have today and racism didn't exist. Twain wrote this book not having to worry about racism. In our day and time they want to censor out the words like nigger but that really would be wrong because it wouldn't be realistic, people need to know what it was truly like. Sheltering people from the truth Is the worst thing you can do. If kids don't learn about how slavery was then they won't truly understand where racism comes from. In the book there is much violence. "It's a dead man. Yes, indeedy naked, too. He's been shot in de back."(pg. 50) The book is better with violence because it becomes more interesting to the reader. It becomes more of a real life situation than just a fairy tale world where nothing goes wrong, because in real life things do go wrong and people do get shot and killed. It is hard to read these kinds of things with death that are gruesome but it helps form feelings for the characters. Also it was necessary for them to find the dead man so that Huck didn't have to worry about pap taking his money. In the scene where Jim finds pap we learn more about Jim and that he is a sensitive person and was cautious not to upset Huck by letting him see pap's body. Many people could have been offended by the stereotypes in this book. For example, "I see it warn't no use wasting words—you can't learn a nigger to argue."(pg. 78) In this example Huck stereotypes Jim as being a stupid nigger that can't learn anything.

Roosevelt a Liberal and Hoover a Conservative

Throughout the history of America conflicting beliefs of how the government should affect our lives has been categorized from either a Liberal or a conservative standpoint. A liberal is one who may be considered a radical, one who believes government has a role to play in our lives and moves towards the new age of humanity. Conservatives share a completely different set of beliefs, they believe in the old ways, a government which doesn't influence our lives, and side with the rights of states and the people. According to these beliefs Hoover follows conservative beliefs more or less and Roosevelt follows a more liberal beliefs. These standpoints can be more defined by comparing them with radicals and influential figures of the age. President Hoover being who he was, was a conservative. Being raised in poverty and still achieving to gain the presidency instilled the idea in him that if he can overcome challenges and economic turmoil so should every other person in the country. Rugged Individualism, as this ideology was called, influenced Hoover against providing direct aid to the people in the Great Depression. To keep the government out of the peoples lives he gave money to business’s and banks with the hope that money would trickle down to the people. As a part of this attempt he created the Reconstruction Finance Corporation in attempt to create jobs for the common people. Providing aver half a billion dollars to indirectly help the poor. (Doc C). Later in his term however Hoover began taking a more liberal stance on important issues. Realizing his previous policies didn't help the people he began asking congress to help fun public work projects. (Doc. B). One of the largest of these projects was the Hoover Dam which provided many jobs to those in need. One of the final changes of heart that Hoover experienced was giving a helping hand to unions. By passing the Norris-La Guardia Anti-Injunction Act he succeeded in outlawing yellow dog contracts, and stopped the use of injunction on strikes and boycotts. These displays of authority during his term proves Hoover to be a developing man of both conservative and liberal beliefs. Roosevelt was a Liberal president, one that strived to bring change to our government, bringing it to terms with the modern era. To bring us out of the depression Roosevelt pulled out as many new and crazy ideas as he could to try and bring our economy back to normal and benefit those in need. (doc. E) Within months of becoming president Roosevelt had already created a number of government based programs to support his three point plan to provide relief, recovery, and reform. In doing this Roosevelt proceeded in one of the most liberal actions of any president, passing the 21st amendment which canceled out another amendment. This amendment allowed for beer and wine to be sold so that the government could receive tax money. The three point plan instilled by Roosevelt included much more then just the legalization of booze. A number of what became known as Alphabet Agencies arose to help ease the need to find jobs. Programs such as the CCC helped with forest protection, while FERA directed by Hopkins granted a few billion dollars to the states to be distributed as seen fit. Other agencies such as ADA or HOLC contributed in other ways to ease the economy. These tendencies prove Roosevelt to be a Liberal president, however he saw himself as a conservative, a savior of democracy in hard times. It was because of his liberal actions that he was able to preserve conservative ways. (Doc. G) By these policies and beliefs it becomes valid point that Roosevelt is much more liberal then he is conservative. Many Influential people of the time and age can help define the outlook these two presidents and exactly where they stand. President Wilson was the embodiment of liberal thinking, bringing the nation into the first world war, making the government a part of every persons life. Coolidge was in contrast to Wilson an embodiment of conservative ideals refusing to give pity to the poor and taking part in their lives. With these marks to judge by the standpoint of Roosevelt and Hoover become very apparent. While Roosevelt may claim to be conservative, he is in fact very liberal, although not nearly as much as Wilson. Hoover may seem to be a conservative, but when compared t Coolidge it becomes clear that he is almost borderline liberal. Whether a president claims to be a liberal or a conservative his true beliefs are hidden until the full extent and intentions of his policies and actions are taken into account. The characterizations that Herbert Hoover was a conservative, and that Franklin Roosevelt is a liberal are both very valid points.

National Cranberry Cooperative

NATIONAL CRANBERRY CO-OPERATIVE CASE STUDY * Nishi Sharma In 1971, National Cranberry Cooperative faced recurring operational problems that affected the productivity and relationship of NCC to growers. This analysis will discuss how NCC can improve its operation before the peak-season comes in. The analysis was based from facts cited in the case, using tools such as but not limited to process flow diagram, cost, benefit and utilization analysis, and work-force scheduling. The author recommends solution that will not just improve NCC's operations but will also increase plant's capacity and decrease its cost thereby leading to long-term savings for the growers. Problem Statement/Key Issues This case analysis will investigate two primary problems faced by NCC (1) Long waiting period of trucks during unloading of berries at RP1 and (2) Too much overtime cost. This case will also look at a secondary problem, specifically, the inaccuracy of grading of berries. Supporting Argument It is necessary to address the truck's queuing problem in 1970 in order to attain NCC's planned increase in output of water harvested crop from 58% to 70% the following year. The queuing/idle time during unloading also creates unnecessary costs particularly the cost of leasing trucks and hiring drivers. Also, Cranberries' market price is influenced by the government regulation Cranberry Marketing Order 1070, which mandates owners to scrap 10% or 200,000 bbls of harvested crops, thereby reducing income for the same resources used. With this, it is important that NCC manage its resources properly including scheduling of workforce (seasonal ; full-time) to reduce the costs like the overtime pay. With the cost amounting to $112,500 ($450,000/2Ãâ€"0. 5) incurred for paying extra premiums to second graded berries, it is important to look at the grading process and assess the need for installing an equipment that can help reduce the said cost. Alternatives The following are the alternatives proposed by Mr. Williston: 1. To buy and install new dryers 2. Convert dry berry holding bins to store water harvested or dry berries 3. Install Light Meter System for color grading PROCESS DIAGRAM – NATIONAL CRANBERRIES CO-OPERATIVE Assumptions:    We have assumed that: †¢ There is a cost associated with trucks waiting to be unloaded and it is $5 per hour. †¢ We have not considered per hour operating    cost of plant †¢ Overtime for both regular and part time worker has been taken to be $ 6. 50 per hour. †¢ In calculating the payback time, the same cost saving will occur every day. It is given in case that wet berries will make 70 % of total berries and that normal running hours for plant is 11 (12-1) hours. Case 1: 10000 bbl/day Wet Berries (WB) ( 7000 bbl/day Dry Berries (DB) ( 3000bbl/day Total Time = 11 Hrs WB feed=7000/11 = 637 bbl/hr DB feed= 3000/11 = 273 bbl/hr Minimum processing rate for WB is at dryers, which is = 600 bbl/hr Minimum processing rate for DB is = 1500 bbl/hr Hence, after 11 hours total accumulation of WB = (637-600)*11 = 407 bbl Overtime = 407/600 = 0. 7 hrs Now, assuming this is not a peak season, we have considered only 27 workers. Since plant is working suboptimal level during overtime , only two-third of the work force will be working on wet berries drying process. =2/3 work force = 20*(2/3) = 12 Savings per day = 12 * 6. 5= 78 Savings for season = 78* 90 = 7020 If we add another dryer, to save overtime cost, cost will be = 40000 Analysis Considering the cost of depreciation and cost of investment in dryer(8-10%) it will not be economical to buy another dryer.

Below, write your answers to Questions 1-4 (on BB/Cases). Your analysis should be based on the assumptions listed in the Syllabus. If you need to make additional assumptions to answer a question, clearly state them, logically defend them, and then proceed to answer the question accordingly.The idea is to answer the questions concisely. Double spacing is preferred, 1. 5-line spacing is the minimum (consider the reader’s eye strain). 1. Mark the capacity and utilization of each resource in the process flow diagram at the end of this document. Briefly describe how you calculate the capacity and utilization here. [20 points] On average, 18000 barrels arrive over the 12hr span that the business is open. This means approximately 1500 barrels of berries are input into the process per hour (18000barrels/12hrs). The capacity of the Kiwanee dumpers was given as 3000 b/hr. and I was able to calculate the implied utilization by dividing the berry input rate by the capacity(1500bbl/hr divided by 3000bbl/hr). To calculate the actual utilization of the dumpers, you must first determine the flow rate of the system. Only 25% of the berries are dry and 75% are wet. This sums to 375 dry berries per hour (1500 input/hr x. 25) and 1125 wet berries per hour (1500 input x . 75). The dry berries have 16 bins that hold 250 barrels a piece, adding up to a total of 4000 berries that can be stored. The wet berries have 8 bins that hold 250 barrels and 3 bins that hold 400 barrels, adding up to 3200 barrels total for storage.The capacity of the DeStoners was given as 1500bbl/hr. The implied utilization would be the input rate (1500bbl/hr) divided by the capacity (1500 bbl/hr). Since the bottleneck does not impact t he dry berries, the actual and implied utilization will be the same for the dry berries in all facets of the operation. The capacity of the Dechaffers for the dry berries was also given as 1500 bbl/hr and once again the implied and actual utilization will be 1. 0. Switching to the Wet Berries, we see that there are two Dechaffers that can each store up to 1500bbl/hr, which will add up to a capacity of 3000bbl/hr.We can calculate the implied utilization of the wet berry Dechaffer by dividing the input rate (1500bbl/hr) by the capacity (3000bbl/hr) and the actual utilization by dividing the Flow Rate (600bbl/hr) by the capacity (3000bbl/hr). The Dryers set the standard for the wet berries because they are the bottleneck of the operation. There are three dryers that can process 200bbl/hr, giving us a total capacity of 600bbl/hr. The implied utilization is not very realistic because it takes the 1500bbl/hr input rate and divides it by the 600bbl/hr capacity. The actual utilization of a bottleneck is always 1. because it is operating at maximum capacity. Lastly, there are three separators that have a capacity of 400bbl/hr each, giving us a total of 1200bbl/hr. The implied utilization will be discovered as 1. 25 because you are taking the 1500bbl/hr input rate and dividing it by 1200bbl/hr capacity. The actual utilization can be found by 600bbl/hr (wet berries) plus 375bbl/hr (dry berries) and using them as your input rate. So you will divide the 975bbl/hr by 1200bbl/hr capacity and get . 8125. 2. Enter your answer and supporting arguments for question 2 here. [10 points] The current maximum throughput rate is 975bbl/hr. 75bbl/hr can be processed by the dry berries because they have the ability to operate at maximum capacity. On the wet berry side, the process is slowed by the dryers, which represent the bottleneck of the operation. Since the dryers can only process 600bbl/hr, we will add the 600bbl/hr and the 375bbl/hr to get a total of 975bbl/hr. 3. Enter your ans wer and supporting arguments for question 3 here. [30 points] *See attached diagram 4. Enter your answer and supporting arguments for question 4 here. [40 points] The possible capital investments I used were adding one more dryer, and swapping one bin from the dry berry operation to the wet berry.Buying the fifth Kiwanee dumper was a misguided investment because the real object should be to increase your bottleneck to speed up the operation. The capacity of the dumpers is 600bbl/hr, so having one less dumper would only drop this to 2400bbl/hr. The throughput rate of the entire system is only 975bbl/hr, so the focus ultimately should be turned to increasing the capacity of the dryers instead of the capacity of the dumpers. The attached excel spreadsheet will explain the ultimate benefits of the proposed capital investments I have offered.

The capacity of the Kiwanee dumpers was given as 3000 b/hr. and I was able to calculate the implied utilization by dividing the berry input rate by the capacity(1500bbl/hr divided by 3000bbl/hr). To calculate the actual utilization of the dumpers, you must first determine the flow rate of the system. Only 25% of the berries are dry and 75% are wet. This sums to 375 dry berries per hour (1500 input/hr x. 25) and 1125 wet berries per hour (1500 input x . 75). The dry berries have 16 bins that hold 250 barrels a piece, adding up to a total of 4000 berries that can be stored. The wet berries have 8 bins that hold 250 barrels and 3 bins that hold 400 barrels, adding up to 3200 barrels total for storage.The capacity of the DeStoners was given as 1500bbl/hr. The implied utilization would be the input rate (1500bbl/hr) divided by the capacity (1500 bbl/hr). Since the bottleneck does not impact t he dry berries, the actual and implied utilization will be the same for the dry berries in all facets of the operation. The capacity of the Dechaffers for the dry berries was also given as 1500 bbl/hr and once again the implied and actual utilization will be 1. 0. Switching to the Wet Berries, we see that there are two Dechaffers that can each store up to 1500bbl/hr, which will add up to a capacity of 3000bbl/hr.We can calculate the implied utilization of the wet berry Dechaffer by dividing the input rate (1500bbl/hr) by the capacity (3000bbl/hr) and the actual utilization by dividing the Flow Rate (600bbl/hr) by the capacity (3000bbl/hr). The Dryers set the standard for the wet berries because they are the bottleneck of the operation. There are three dryers that can process 200bbl/hr, giving us a total capacity of 600bbl/hr. The implied utilization is not very realistic because it takes the 1500bbl/hr input rate and divides it by the 600bbl/hr capacity. The actual utilization of a bottleneck is always 1. because it is operating at maximum capacity. Lastly, there are three separators that have a capacity of 400bbl/hr each, giving us a total of 1200bbl/hr. The implied utilization will be discovered as 1. 25 because you are taking the 1500bbl/hr input rate and dividing it by 1200bbl/hr capacity. The actual utilization can be found by 600bbl/hr (wet berries) plus 375bbl/hr (dry berries) and using them as your input rate. So you will divide the 975bbl/hr by 1200bbl/hr capacity and get . 8125. 2. Enter your answer and supporting arguments for question 2 here. [10 points] The current maximum throughput rate is 975bbl/hr. 75bbl/hr can be processed by the dry berries because they have the ability to operate at maximum capacity. On the wet berry side, the process is slowed by the dryers, which represent the bottleneck of the operation. Since the dryers can only process 600bbl/hr, we will add the 600bbl/hr and the 375bbl/hr to get a total of 975bbl/hr. 3. Enter your ans wer and supporting arguments for question 3 here. [30 points] *See attached diagram 4. Enter your answer and supporting arguments for question 4 here. [40 points] The possible capital investments I used were adding one more dryer, and swapping one bin from the dry berry operation to the wet berry.Buying the fifth Kiwanee dumper was a misguided investment because the real object should be to increase your bottleneck to speed up the operation. The capacity of the dumpers is 600bbl/hr, so having one less dumper would only drop this to 2400bbl/hr. The throughput rate of the entire system is only 975bbl/hr, so the focus ultimately should be turned to increasing the capacity of the dryers instead of the capacity of the dumpers. The attached excel spreadsheet will explain the ultimate benefits of the proposed capital investments I have offered.

Comparison Of Different Waste Management Techniques Environmental Sciences Essay

Like incineration, gasification is a thermic procedure that uses high temperatures to interrupt down waste. It is still classed as incineration in the European Unions Waste Incineration Directive and has to run into the compulsory emanation bounds that it sets. Gasification is a procedure in which stuffs are exposed to some O, but non plenty to let burning to happen. The ensuing gas mixture of C monoxide, H and methane ( with smaller measures of C dioxide and N ) is called syngas and is itself a fuel. It has a calorific value so can be used as a fuel to bring forth electricity or steam or as a basic chemical feedstock in the petrochemical and refinement industries. The calorific value of the syngas will depend on the composing of the input waste waste to the gasifier. Both gasification and incineration are capable of change overing hydrocarbon-based risky stuffs to simple, nonhazardous by-products ( A Comparison of Gasification and Incineration of Hazardous Wastes Final Report Prepared for: U.S. Department of Energy March 30, 2000. There is non much indifferent informations available on gasification but the companies developing gasification claim the engineering has important advantages over traditional incineration of waste. These are as follows The procedure uses less oxygen significance that fewer air emanations may be produced incorporating possible pollutants. Less C dioxide is produced intending less impact on planetary clime alteration. Any C dioxide produced during gasification is present at much higher concentrations and at higher force per unit areas than in watercourses produced from conventional burning, doing them easier to capture ( hypertext transfer protocol: //www.netl.doe.gov/technologies/coalpower/gasification/basics/2.html ) The workss are are made up of little units ( modular ) which can be added to or taken off from as waste watercourses or volumes change ( e.g. with increased recycling in state ) and are hence more flexible and can run at a smaller graduated table than mass burn incinerators They are quicker to construct than conventional incinerators The procedures are claimed to bring forth a more utile merchandise than standard incineration that can be used as a fuel ( syngas ) The syngas may be used to bring forth energy more expeditiously, if a gas engine ( and potentially a fuel cell ) is used, while incineration can merely bring forth energy less expeditiously via steam turbines. ( Source – Eunomia Research and Consulting ( 2008 ) . Greenhouse gas balances of waste direction scenarios – study for the Greater London Authority ) .The syngas produced by gasification can be converted into many valuable merchandises, runing from electricity and steam to liquid fuels, basic chemicals, and H. Integration of multiple merchandises of gasification into industrial applications increases chances for added grosss The energy produced from gasification may be eligible for more Reclamations Obligations Certificates ( ROC ‘s ) than conventional incineration therefore increasing the possible income The treated fluke gas from an incinerator goes straight out into the ambiance. The treated syngas from the gasification works is used as a fuel in itself. When solid waste is incinerated one of the by merchandises is bottom ash which so has to be disposed of or treated and so disposed of depending on the content. When solid is processed in a gasifier, scoria is produced which can be can be sold, used as feedstock in chemical production processes, or recycled in other in-plant procedure operations. Sulfur compounds ( H2S and COS ) in the particulate-free syngas, usually a by-product of liquid gasification are typically removed and recovered utilizing conventional gas intervention engineerings from the refinery and natural gas industries. The ensuing by-product is high-purity liquid S which can so be sold and reused. ( A comparasion of gasification and incineration of risky wastes. Concluding Report. Prepared for the U.S. Department of Energy. March 2000 ) Emission degrees of SOx, NOx, and particulate from gasification systems are reduced significantly compared to incineration systems. In an oxidative incineration environment, S and N compounds in the provender are converted to SOx and NOx. In contrast, syngas killing systems for modern gasification systems are designed to recover 95 to 99 % of the S in the fuel as a high-purity S by-product A comparasion of gasification and incineration of risky wastes. Concluding Report. Prepared for the U.S. Department of Energy. March 2000 )The factors impacting the pick of bag filters or ESP in waste incinerators.Factor one: The type of waste being incinerated It all depends on what is being incinerated. . The features of the dust produced by the incineration plays a function in the pick as the combustibleness of some all right stuffs regulations out the usage of electrostatic precipitators. Bag filters are really efficient at roll uping all right particulates but non so good at big particulates so it depends on the merchandise of the incineration. ( Source Should I replace my Electrostatic Precipitator with a fabric filter, I. Fanthom, C. Cottingham. ) Most common ESP filtration is best used for ambient gaining control of light atmospheric dust. Unless a hob cleaning electrostatic precipitator is used, beginning gaining control or direct ducting from a heavy dust bring forthing incineration will rapidly make full up the aggregation plates. Heavy dust aggregation requires storage for a big volume of dust. The surface country of bag filters is much greater than surface country of electrostatic aggregation home bases and work better for dust gaining control of heavy dust bring forthing incineration than ESP would. ( hypertext transfer protocol: //www.dustcollectorexperts.com/electrostatic/ ) Factor two: Features of the airstream The features of the airstream can hold important impacts on the aggregator system. For illustration cotton cloth bag filters can non be used where air temperatures exceed 82 grades centigrade. Besides condensation of steam or H2O vapors can blind bags doing them uneffective. Assorted chemicals created in the airstream can respond with the H2O in the airstream and signifier caustic liquids such as sulfuric acid which can eat any metal in the bag i.e. if it is rearward jet bag filter with a metal coop. ESP ‘s can defy caustic stuff doing aggregation possible. The individual most of import factor act uponing the Elecrostatic precipitator is the electric resistance of the gas being caught. Fabric filters take dust from a gas watercourse by go throughing gas through a cloth and go forthing dust on the surface of the cloth. It is hence non sensitive to dust electric resistance. A fabric filter can work on emanation degrees of 10-20 mg/NM3 whereas an ESP needs to be sized to suit demands. Factor three – Cost With most designs of ESP ‘s they have to close the line down in order to keep them which incurs a cost. With most bag filters they can be changed online, non incurring a cost of closing down. The power ingestion utilizing a bag filter is higher than utilizing an ESP, evidently incurring more costs for more power. Bag filters need to be changed more often than an Electrostatic Precipitator. Typically bags need altering every 4 old ages. An ESP needs a full service every 20-30 old ages. Bag filters are extremely efficient and cost effectual due to the dust bar which is formed on the surface. ( ( Source Should I replace my Electrostatic Precipitator with a fabric filter, I. Fanthom, C. Cottingham. ) They can accomplish a aggregation efficiency of more than 99 % for really all right particulates. The ESP ‘s are more expensive to put in than the bag filters Dust tonss may be needed to be reduced before the Electrostatic Precipitation procedure ( precleaner may be needed ) hence adding to the cost. Factor four – Features of the dust. Hygroscopic ( i.e. a stuff which attracts wet from the ambiance. If non protected from contact with the ambiance ( by being stored under vacuity or under a dry gas ) some hygroscopic stuffs will finally pull so much H2O that they will organize solutions ) and these can blind bag filters doing them ineffective. Factor Five – Conformity with Environmental ordinances and jurisprudence. In 1990the Environmental protection Act ( EPA ) introduced Integrated Pollution Control ( IPC ) necessitating higher control of emanations in most industries. More late the waste Incineration Directive was introduced and has imposed important alterations on any procedure combustion waste stuffs. For illustration the entire emanation value for Cd is 0.05 mg/Nm3. ( Source the Waste Incineration Directive ) . Hence the type of intervention demands to be chosen in order to fulfill these ordinances. It will besides depend how near the waste incinerator is to edifices and the type of edifice i.e. is it near a residential country. Hence more ordinances need to be considered sing public wellness. Factor Six- Space How much infinite is at that place for the installings. ESP ‘s are larger than bag filters and therefore take up more infinite.Methods for cut downing heavy metals in landfill leachate.There are assorted methods for cut downing heavy metals in landfill leachate -biological, biodegredation utilizing anaerobiotic and aerophilic procedures and chemical and physical methods. One such biological intervention that has been investigated is utilizing vertiver grass ( N. Roongtanakiat, T.Nirunrach, S.Chanyotha, D. Hengchaovanich. Uptake of heavy metals in landfill leachate by vertiver grass ‘ Natural Science 37: 168-175. 2003 ) . They investigated the workss ability to uptake heavy metals from the leachate. The Surat ecotype vertiver workss were planted in pots and treated with landfill leachate. The vertiver grass took up more heavy metals as the strength of the leachate increased and the heavy metals were equally distributed in the shoot and the root. The consequences of the field test at the landfill site besides indicated that vertiver could be used in rehabilitating landfills and nearby countries. The vertiver workss were shown to decease after 80-85 yearss if 100 % leachate was used so they could non e straight used on immature landfills, but could be used on immature landfills if limited leachate were used. The shoot of the works should be harves ted sporadically in order to take the heavy metals from the contaminated dirt and to excite new growing for more consumption. Artificial wetlands combined with aerophilic interventions have besides been studied as a remotion method for heavy metals in leachate. The survey was undertaken at Alback landfill site in Sweden In 2003. ( Source – hypertext transfer protocol: //warrr.org/168/ ) . The leachate intervention system consists foremost of an aeration measure, followed by several wetlands with different deepnesss and flora, intermediate commixture and aeration in a ditch, and eventually deposit in a pool. An approximative sum of 120,000 M3 of leachate base on ballss through the intervention stairss yearly. Leachate samples were collected at different phases along the intervention way during a period of two months and the concentrations of Cd, Cu, Zn, nickel, lead and Cr were studied. The leachate samples were filtered with three different membranes with different pore sizes. Lead and Cr could non be detected at all in the leachate. The entire rates of decrease in the whole wetland system for Cd, Cu , and Zn concentrations were on mean – 83 % 74 % and 68 % severally. Nickel passed unchanged through the wetlands. The largest sum of metals in the leachate was already reduced during the first few metres in the wetland system, provided by deposit and aeration. Consequences of fractional process indicate that Ni and copperoccurred chiefly complex-bound to humic substances. Which are difficult to entree automatically or biologically. Zinc occurs largely in different ionic signifiers or bonded to atoms in the H2O. Harmonizing to environmental quality standards for natural Waterss in Sweden controlled by the Swedish Environmental Protection Agency, metal concentrations in the treated leachate are low and give rise to no or small hazard of biological effects. Further betterment to the wetland system ‘s heavy metal remotion rates is likely limited since a big sum of the metals appear as composites, which are difficult to entree automatically or biologically.

In: Eleventh International Waste Management and Landfill Symposium, 1-5 October 2007, S.Margherita di Pula – Cagliari, Sardinia, Italy. hypertext transfer protocol: //warrr.org/168/ ) Aerobic intervention can be used where leachate is recirculated through the waste mass and air is injected into the waste mass. An probe by M.Sartaj, M. Ahmardifar, A.Karmi Jastini ‘ ( Assessment of unmoved aerophilic intervention of municipal landfill leachate at research lab degree – Persian Journal of Science and Technology, Transaction B, Engineering. Vol 34 No.Bl. Pp107-116 2010 ) found that the remotion efficiency for Magnesium, Iron, Lead and Zinc was 93 % , 90 % , 43 % and 76 % severally. Leachate was collected in a container at the underside and pumped into another container at the top, from which leachate was recirculated back into the waste mass into which air was injected. Bacterias can be used to handle leachate for heavy metals. Bacterial floc on the on the leachate surviving in an aerated system with O degrees maintained above 5mg/l. The heavy metals are taken in by the bacteriums and incorporated into their cell biomass. ( Source – Arden Quarry Landfill – www.drydenaqua.com/leachate/leachate/leachpapers/123pdf ) Chemical intervention is besides used – Three armored combat vehicles are used in which pH is adjusted, metal precipate atoms coagulate and are flocculated and foods are added to promote microbic growing The usage of ferric and ferrous oxides as coagulates separate and clot the heavy metals leting remotion. The usage of oxidizers such as H peroxide or K permanganate react with the heavy metals and pull them out of the leachate leting remotion. Simple pH accommodation of the leachate causes the heavy metals to precipitate from the leachate and therefore be removed. ( Source – www.epa.gov/nrmrl ) Other methods include revolving biological contractors, drip filters, aerated lagunas, up flow anaerobic sludge cover reactors, chemical oxidization, surface assimilation, deposit, floatation, rearward osmosis and air denudation.Techniques for the separation of plastic types originating from municipal wastesPlastics can be separated by their rosin designation codification, a method of classification developed by the Society of the Plastics Industry in 168. See below Pet Polyethylene phenolphthalein – Fizzy drink bottles and oven-ready repast trays. HDPE High-density polythene – Bottles for milk and washing-up liquids. Polyvinyl chloride Polyvinyl chloride – Food trays, cleaving movie, bottles for squash, mineral H2O and shampoo.LDPE Low denseness polythene – Carrier bags and bin line drives. PP Polypropylene – Margarine bath, microwaveable repast trays. PS Polystyrene – Yoghurt pots, foam meat or fish trays, beefburger boxes and egg cartons, peddling cups, fictile cutter, protective packaging for electronic goods and playthings. OTHER Any other plastics that do non fall into any of the above classs. – An illustration is melamine, which is frequently used in plastic home bases and cups. ( Source hypertext transfer protocol: //www.wasteonline.org.uk/resources/informationsheets/plastics.htm ) The first point of separation can be at the clip of aggregation. The rosin codification is identified, as seen above, by a trigon formed by three trailing pointers with a figure indoors. This system allows segregation by what is desirable for a municipal recycling segregation system and what should non be included. Other types of separation include: DRY SEPARATION, utilizing the following techniques: Air classifiers -Air separation is used to divide different plastics, or even the same plastic, by the difference of the ratio between the surface of the flake and its mass. This is done by an air counter-flow, – an air flow lifts up plastics of light denseness material and the high denseness plastic corsets down utilizing gravitation. Mechanical classifiers -These are used on flakes of plastic and are largely used to divide flakes by size. Classifiers can be round, level, inclined, with slow or high frequence quivers etc. NIR ( Near Infrared Rays ) – These give a certain measure of energy to every individual piece of plastic and step the response ; this happens in footings of msecs. Its bound is the fact it can be used merely on crystalline points ( chiefly to screen PVC from PET bottles and flakes ) Laser spectral analysis -This penetrates the surface and steps emission spectra which depends upon heat capacity and thermic conduction so color does n't count. The response clip is long on this method so it is non mostly used. Polarized visible radiation -This used to look into differences of crystallinity and applies chiefly to the sorting of PVC from PET bottles but it can be used to screen any mixture of two plastics. UV light – This is used to divide polymers that exhibit different UV induced fluorescence. To human eyes, PET will remain clear while PVC turns black therefore this is a really common manner to manually screen bottles. Electrostatic separation is a system to pull or repel different plastics harmonizing to their charge.–WET SEPARATION, utilizing the following techniquesHydro cyclones heighten the difference of specific weight by centrifugal force, so seperating the plastics. It can be used on plastics of really similar weightsSink-float by preferable solvent soaking up is used when two polymers with same specific weight demand to be separated ; a dissolver ( intoxicant, ketone, etc ) makes one of the two lighter hence they can be separated. Hydrophobicity is the disfavor of H2O ; some polymers react in a different manner when traveling into H2O under certain conditions therefore separation becomes possible.Froth floatation means air bubbles attach to one solid advancing natation in a liquid and leave the other ( s ) to drop. Chemical Separation can besides be used including Hydrolysis, Glycolysis, hydroglycolysis .PyrolysisA new separation technique for assorted plastics using selective wetting features has been developed. The surface of specific plastics can be selectively changed from hydrophobic to hydrophilic by utilizing a wetting agent. Then, when little air bubbles are introduced into a separation cell, they adhere to the surface of the hydrophobic plastics and drift them to the H2O surface. The new separation technique is wholly different from conventional methods based on lone differences in denseness. Plastics with the same denseness can be separated by this procedure. The fictile centrifuge can be used for many intents: for dividing plastics from mixtures, riddance of foreign affair such as paper, fibres, aluminum foil, Cu wire french friess, sand, and glass from plastics ; elucidation of waste H2O incorporating all right rosin pulverization ; etc. ( Source K.Saitoh, I.

Environmental Economics Analysis Term Paper Example | Topics and Well Written Essays - 3500 words

Environmental Economics Analysis - Term Paper Example Environmental economics is a subfield of economics concerned with environmental issues (other usages of the term are not uncommon). In using standard methods of neo-classical economics, it is distinguished from green economics or ecological economics, which include the nonstandard approaches to environmental problems, environmental science/environmental studies, or ecology. (Wikipedia) The economic growth is, in fact, good for the environment, and there are limits to the contribution that economic growth can make to human well being. Forests are being depleted throughout the world since this is the economically optimal strategy for the owners. However, forests not only provide timber but also perform global ecosystem services. Forests absorb carbon dioxide, preserve biodiversity, prevent soil erosion, maintain hydrological cycle, etc. Hence, global environmental sustainability, a prerequisite for economic sustainability, might require that limits be placed on the depletion of natural resource stocks, even if it appears that this means sacrificing some of the monetary value of these stocks As the market cannot reflect all the values of the services provided by the natural environment, this implies that environmental sustainability places a constraint on economic growth. Because the services provided by natural resources are not traded in the markets, they are not reflected in the value of conserving natural resource stocks. In economic terminology, these are examples of market failures, and that is an outcome, which is not efficient in an economic sense. Here the inefficiency is caused because too much of the polluting activity will be carried out, as the polluter will not take the interests of those adversely affected by the pollution into account. This has led to controversial research into measuring well being which tries to measure when pollution is actually starting to affect human health and general quality of life.  Ã‚
