New York Incineration Case Study

The way in which New York city (NYC) manages its rot is dominantly based upon landfill. though this is non the best solution is sparks controversy throughout Staten Island where the deva earth is dumped as many claim. Why is this so? NYC has a problem with managing its redundance as NYC alone creates 26,000 tons of dissipation per day half(prenominal) of which is commercial and the proportionality is residential. Nevertheless, private companies collect commercial barren leaving residential waste to NYCs department of Sanitation. The sole destination for 13,000tons of residential waste is the Fresh Kills Landfill on Staten Island. The highest mound is 180feet high, twenty inches higher than the statue of libertyThe Fresh Kills Landfill rank on the Western side of The Staten Island is the - still- landfill settle that remains open. It has served NYC for over half a century it was due to close on the 31st December 2001. It current 12-14,000 tons of solid household waste per day, by a igniter from four other boroughs. The key problem with it is that it only has 5% of the citys tribe and on top of that it is the smallest place.Though not everything about Staten Island is a invalidating this could be because the garbage industry provides economic development, jobs and increased spending origin follow. To operate the landfill site requires 500 employees whose jobs range from crane and tractor operators to chemists and geologists. Although the daily pot of waste is high there has been a decrease in waste it has fallen from 21,200tons per day in 1986 to 13,000tons per day in 1995.You can remove also Costco Case StudyFresh Kills Landfill site attempts every sentry duty to ensure that it is environmentally friendly. It does it by following these simple steps supervise System Allows checks to be made of the build-up of the landfill gas, as well as the cause of operation on ground and surface water supplies. And landfill slope stability is examined re gularly. Litter Prevention The barges are covered with nets during transport, while booms contain bedclothes some the waters of the landfill site. Fences around the perimeter of the operation have the aforesaid(prenominal) effect on the island. Landscaping Ecologists are working to introduce domestic plant varieties tolerant of the conditions in an attempt to establish the area as a wildlife habitat. Leachate Treatment Plant To prevent percolating rainwater from becoming polluted the plant removes pollutants prior to the water being returned to the waterways. Construction Debris cycle Area Processes 750tons per day of debris, e.g. concrete, asphalt and soil. Steel is extracted from the process and sold for recycle. The ingathering is used to construct the roads throughout the landfill site. Composting Facility Garden waste is collected and turned into compost. It is used in the landscaping process around the site. It is also made available to the public free of charge. La ndfill Gas recuperation Consisting of primarily methane and carbon dioxide, landfill gas is collected and customized at the facility onsite. The methane is purified into argumentation quality gas, which is and then sold to a local company.Nevertheless situation is limited and a 2 decade estimate has been put on the Fresh Kills site meaning that a more long-term come on path to wasted handling will have to be in effect.Managing waste in the futureIn spite of predictions in 1996 that the Fresh Kills Landfill site could operate for another two decades, Mayor Guiliani announced the closure of the site in 2001. He proposed that there had to be a new approach in dealing with the Citys waste, and he publicised the creation of a line of work force on the Fresh Kills closure. Five recommendations were put forward* increase Recycling* Promoting waste reduction* Encouraging waste prevention* Refusing the exporting of waste elsewhere* Supporting education about waste and cycleNow the re is a recycling drive throughout the City which now means that every household is part of the Curbside Program, where waste for recycling is collected from the roadside. A contracted was negotiated with Visy Paper (NY) Inc., who constructed and now operates a $150million recycled penning mill on Staten Island. It is the largest manufacturing project in NYC in 50 forms. It employed 1,000people during pull and now has a labour force of 115. Also, NYCs mayor has pledged to not build or renovate any incinerators in the city.But then again, there are still problems because what is proposed of the commercial waste which accounts for the other half? After 2001, it will be recycling waste prevention and waste reduction schemes as good as they all may be, is it authentically probable that they will be able to absorb 13,000tons of waste on a daily basis? One person who is not convinced is the state Governor of Pennsylvania, Tom Ridge.Garbage Importers & ExportersThe state of Virginia is a number two importer after Pennsylvania, with NYC accounting for 60% of Virginias imports. A survey by Virginia ground University found that 87% of people were keen to limit garbage imports with only 9% opposing. Mainly the ones opposing argued that there would be a wrong of revenue and would hurt communities where garbage is a big business. With imports totalling 4million tons per year there is hardly
