Transforming New York’s Fresh Kills LandfillTransforming New York’s Fresh Kills Landfill

• Fresh Kills, on New York’s Staten Island, is the largest landfill in the world.

• It closed in 2001, forcing New York City to find other places for its trash, at great expense to taxpayers.

• Today the landfill is in the process of becoming a public park.

Methods of Solid Waste Disposal: Sanitary Landfills

• Waste buried in the ground or carefully piled into mounds

• Designed to prevent groundwater contamination and minimize soil and air pollution

Benefits and Costs of LandfillsBenefits and Costs of Landfills

Lesson 19.1 Municipal and Industrial Waste

Benefits Costs

Decomposition yields methane, which can be used like natural gas.

Leachate may eventually escape and contaminate the groundwater.

When full, landfills are capped. The land can be used for recreation.

Trash decomposes very slowly.

Few communities are willing to host landfills (NIMBY).

A power company in Hull, Massachusetts installed a large wind turbine on a site that had previously been a landfill.

As a result of the NIMBY syndrome, landfills are rarely located in neighborhoods that are home to wealthy and educated people with the political power to keep them out.

Lesson 19.1 Municipal and Industrial Waste

Benefits Costs

Incinerating waste reduces its weight by up to 75% and volume by up to 90%.

Toxic ash must be disposed of.

Heat from burning trash can be used to generate electricity (waste-to-energy).

Dioxins, heavy metals, and PCBs can be created and released by burning waste.

Toxic Substances Control Act Incinerator The only U.S. facility permitted to burn certain hazardous wastes

Waste Reduction MethodsWaste Reduction Methods

Lesson 19.2 Minimizing Solid Waste

• Substitute disposable goods with reusable ones.

• Donate unwanted items.

• Minimize packaging.

• Reduce use of nonbiodegradable plastic.

• Design goods to last.

• Use financial incentives such as “pay as you throw” garbage disposal and “bottle bills.”

Did You Know? States with “bottle bills” (consumers receive a refund per returned bottle or can) have reduced their beverage container litter by 69–84% and total litter by 30–64%.

Waste Recovery: CompostingWaste Recovery: Composting

Lesson 19.2 Minimizing Solid Waste

• Conversion of organic waste into mulch or humus by decomposition

• Currently 3800 municipal programs in the U.S.

• Has many benefits, including soil enrichment

Did You Know? About 20% of U.S. waste is made up of organic material that could be composted.

Waste Recovery: RecyclingWaste Recovery: Recycling

Lesson 19.2 Minimizing Solid Waste

• Collection and reprocessing of waste materials

• Recycling rates among U.S. communities vary from 5 to 50%.

• Many programs run at a financial loss, but that doesn’t take into account the effects of not recycling.

Hazardous Waste DisposalHazardous Waste Disposal

• Landfills: Specifically designed to keep hazardous waste contained

• Surface impoundment: Liquid waste poured into shallow lined pits; water evaporates and solid waste is transported elsewhere

• Deep-well injection (see diagram on right): Wastes injected into deep, confined porous rock layers

Radioactive WasteRadioactive Waste

Lesson 19.3 Hazardous Waste

• Waste that gives off harmful radiation• Low-level: Less harmful; produced by

hospitals, labs, uranium mines

• High-level: More harmful; produced by nuclear power plants

• Difficult to dispose of safely due to long half-lives

Did You Know? As of March 2010, the Obama administration has ruled out Yucca Mountain for long-term storage of high-level radioactive waste.

Some nations make manufacturers responsible for reducing e-waste. Companies

must recover used and discarded electronic devices that they sell to consumers. Do you think this is a

good idea? Why or why not? If not, offer an alternative means of
