Waste Management 19 CHAPTER Placeholder opening page, but maybe we can duplicate the look of the SE chapter opener page by using the same fonts and colors (and maybe that Ch 14 icon?)

Transforming 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. Talk About It Which should play a greater role in reducing the waste we generate—personal choices by consumers or government regulation?

Lesson 19.1 Municipal and Industrial Waste Of all the solid waste produced in the United States, 33.9% is made up of paper. How much waste do you generate?

According to the EPA… The average American produces more than 4.5 pounds of garbage a day! This is 29 pounds per week and 1,600 pounds per year! America produces enough garbage to form a line of garbage trucks to reach the moon, cover the state of Texas 2 ½ times, or bury more than 990,000 football fields!

Lesson 19.1 Municipal and Industrial Waste What Is Waste? Did You Know? The average American generates more than 4.5 pounds of trash per day. Any unwanted material or substance that results from a human activity or process Municipal solid waste: From homes and businesses Industrial waste: Resulting from manufacturing, agriculture, and mining Hazardous waste: Toxic, reactive, flammable, and corrosive Wastewater: Includes used, discarded water and runoff

Lesson 19.1 Municipal and Industrial Waste What Is Waste?

Methods of Solid Waste Disposal: Sanitary Landfills Lesson 19.1 Municipal and Industrial Waste 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 Did You Know? Regulations require that landfills be at least 6 m above the water table.

Benefits and Costs of Landfills Lesson 19.1 Municipal and Industrial Waste Benefits and Costs of Landfills 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). Ohio Leak A power company in Hull, Massachusetts installed a large wind turbine on a site that had previously been a landfill.

What Is NIMBY? Not in my backyard! Lesson 19.1 Municipal and Industrial Waste What Is NIMBY? Not in my backyard! 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 Incineration

Benefits and Cost of Incineration Lesson 19.1 Municipal and Industrial Waste Benefits and Cost of Incineration 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. SWEDEN NEEDS YOUR HELP! Toxic Substances Control Act Incinerator The only U.S. facility permitted to burn certain hazardous wastes

Lesson 19.2 Minimizing Solid Waste TED: Pacific Garbage Patch In 2007, Americans recycled or composted nearly 1/3 of municipal solid waste, saving energy equivalent to 10 billion gallons of gas.

Waste Reduction Methods Lesson 19.2 Minimizing Solid Waste Waste Reduction Methods 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: Composting Lesson 19.2 Minimizing Solid Waste Waste Recovery: Composting 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: Recycling Lesson 19.2 Minimizing Solid Waste Waste Recovery: Recycling 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.

QUESTION!! True or False: The amount of waste has significantly decreased due to the advancement of computers and technology.

ANSWER!! False! Its generated a new type of waste! Computers, printers, copiers, VCRs, DVDs, fax machines, iPads, iPad mini, iPod, iPhone, PSP, xBOX, GPS, Android, Nooks, Kindles….You get the picture.

Lesson 19.3 Hazardous Waste Common sources of hazardous waste include batteries, cleaning agents, paints, and pesticides. E-Waste

What are the four criteria used to define hazardous waste? QUESTION!! What are the four criteria used to define hazardous waste?

What Is Hazardous Waste? WRITE THIS!  What Is Hazardous Waste? Ignitable: Can catch fire Corrosive: Can damage or destroy metals Reactive: Chemically unstable; can explode or produce fumes when combined with water Toxic: Harmful or fatal when inhaled, ingested, or touched

Sources of Hazardous Waste DON’T WRITE THIS!  Sources of Hazardous Waste Industry produces the most hazardous waste, but it is usually highly regulated. Household hazardous waste is unregulated. Did You Know? The average American home contains about 100 pounds of hazardous waste in different products.

Which are hazardous waste? Paint Cosmetics Laundry Bleach Styrofoam Plastic Nail Polish

Types of Hazardous Waste DON’T WRITE THIS!  Types of Hazardous Waste Organic compounds: Can act as mutagens, carcinogens, teratogens, and endocrine disruptors Heavy metals: Many cause neurological damage over time. E-waste: Contains heavy metals and toxic chemicals, but mostly treated as conventional solid waste Did You Know? U.S. households threw out about 304 million electronic devices in 2005—most were still in working order.

Hazardous Waste Disposal DON’T WRITE THIS!  Hazardous 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 Waste Waste that gives off harmful radiation Lesson 19.3 Hazardous Waste Radioactive 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.

Hazardous Waste Regulation Lesson 19.3 Hazardous Waste Hazardous Waste Regulation Resource Conservation and Recovery Act (RCRA): Sets standards for hazardous waste management by states; requires industry to track hazardous material “cradle to grave” Comprehensive Environmental Response Compensation and Liability Act (CERCLA), or “Superfund” Act: Federal program for cleaning up sites polluted by hazardous waste; culprits held liable for damage caused by their pollution Did You Know? As of 2007, 1354 of the 1569 Superfund sites have been cleaned up.

FORM AN OPINION!! 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 reducing e-waste.

QUESTION!! The Resource Conservation and Recovery Act requires large generators of hazardous waste to track hazardous materials “from cradle to grave.” Explain what this means.
