Title: Chapter 23 Solid and Hazardous Waste
1Chapter 23Solid and Hazardous Waste
2Question of the day
- From when you woke up till APES class, make a
list of all the things you have thrown away? - Do you think about the packaging of a product
before you buy it? (How about those
Starbucks/Wawa cups?) - How often do you reuse objects, recycle objects?
3Question of the day
- List the top five materials that you think get
thrown away into landfills. - At your house, what would be your top five
materials thrown away.
4Overview of Chapter 23

5Activity
- In small groups, you are going to research an
assigned recycling topic. - Write down some facts and information on easel
paper. Present to class your topic. - Read selected article.
- Summarize article in one paragraph. Be able to
teach someone else about your article. Include
some facts and figures.
6Solid Waste
- US generates more solid waste per capita than any
other country - 1.98 kg per person per day
- Types of Solid Waste
- Municipal solid waste
- Solid material discarded by homes, office
buildings, retail stores, schools, hospitals,
prisons, etc - Relatively small portion of solid waste produced
- Non-municipal solid waste
- Solid waste generated by industry, agriculture,
and mining

8Composition of Municipal Solid Waste
9Disposal of Solid Waste
- Three methods
- Sanitary Landfills
- Incineration
- Recycling
10Sanitary Landfill
- Compacting and burying waste under a shallow
layer of soil - Most common method of disposal
11Chester County Solid Waste Authority

12Sanitary Landfill
- Problems
- Methane gas production by microorganisms
- Contamination of surface water ground water by
leachate - Not a long-term remedy
- Few new facilities being opened
- Closing a full landfill is very expensive
13Sanitary Landfill
- Special Problem of Plastic
- Much of plastic is from packaging
- Chemically stable and do not readily break down
and decompose
- Special Problem of Tires
- Cannot be melted and reused for tires
- Made from materials that cannot be recycled
- Can be incinerated or shredded

15The Plastic problem
- Pacific Ocean Garbage Issue
- DVD-Clip from Wired Science
16Question of the day
- Why is plastic debris a problem in our oceans?
- What is the name of the garbage patch in the
Pacific Ocean? - How could you help reduce this plastic burden?
17Incineration
- Volume of solid waste reduced by 90
- Produces heat that can make steam to generate
electricity - Produce less carbon emissions than fossil fuel
power plants (right)
18Incineration
- Types of Incinerators
- Mass burn (below)
- Modular
- Refuse-derived
19Incinerator
- Problems Associated with Incineration
- Yields air pollution
- Produce large amounts of ash
- Site selection often controversial

21Composting
- Includes
- Food scraps
- Sewage sludge
- Agricultural manure
- Yard waste
- Reduces yard waste in landfills
- Can be sold or distributed to community

24Waste Prevention
- Three Goals
- (1) Reduce the amount of waste
- (2) Reuse products
- (3) Recycle materials
25Reducing Waste
- Purchase products with less packaging
26Reducing Waste
- Source reduction
- Products are designed and manufactured in ways
that decrease the volume of solid waste in the
waste stream - Pollution Prevention Act (1990)
- Dematerialization
- Progressive decrease in the size and weight of a
product as a result of technological improvements
27Reusing Products
- Refilling glass beverage bottles
- Heavier glass that costs more
- Japan recycles almost all bottles
- Reused 20 times
28Recycling Materials
- Every ton of recycled paper saves
- 17 trees
- 7000 gallons of water
- 4100 kwatt-hrs of energy
- 3 cubic yards of landfill space
- Recycle
- Glass bottles, newspapers, steel cans, plastic
bottles, cardboard, office paper
29Recycling
- Recycling Paper
- US recycles 50
- Many developed countries are higher
- Recycling Glass
- US recycles 25
- Costs less than new glass
- Can be used to make glassphalt (right)
30Recycling
- Recycling Aluminum
- Making new can from recycled one costs far less
than making a brand new one
31Recycling
- Recycling Metals other than Aluminum
- Lead, gold, iron, steel, silver and zinc
- Metallic composition is often unknown
- Makes recycling difficult
- Recycling Plastic
- Less than 20 is recycled
- Less expensive to make from raw materials
32Recycling
- Recycling Tires
- Few products are made from old tires
- Playground equipment
- Trashcans
- Garden hose
- Carpet
- Roofing materials
- 36 of tires are currently recycled to make other
products
33Upcycle- Todays Project-. Create! Creativity!

38Integrated Waste Management
39Question of the day
- 1. What qualifies as hazardous waste?
- 2. Why do you think it needs separate disposal?
- What is Superfund? (just guess)
40Hazardous Waste
- Any discarded chemical that threatens human
health or the environment - Reactive, corrosive, explosive or toxic chemicals
- Types of Hazardous Waste
- Dioxins
- PCBs
- Radioactive waste
41Management of Hazardous Waste
- Chemical accidents
- National Response Center notified
- Typically involves oil, gasoline or other
petroleum spill - Current Management Policies
- Resource Conservation and Recovery Act (1976,
1984) - Comprehensive Environmental Response,
Compensation, and Liability Act (1980)
42Resource Conservation and Recovery Act (1976,
1984)
- The Resource Conservation and Recovery Act (RCRA)
gives EPA the authority to control hazardous
waste from the "cradle-to-grave." This includes
the generation, transportation, treatment,
storage, and disposal of hazardous waste. RCRA
also set forth a framework for the management of
non-hazardous solid wastes. The 1986 amendments
to RCRA enabled EPA to address environmental
problems that could result from underground tanks
storing petroleum and other hazardous substances. - HSWA - the Federal Hazardous and Solid Waste
Amendments - are the 1984 amendments to RCRA that
focused on waste minimization and phasing out
land disposal of hazardous waste as well as
corrective action for releases. Some of the other
mandates of this law include increased
enforcement authority for EPA, more stringent
hazardous waste management standards, and a
comprehensive underground storage tank program.
43Management of Hazardous Waste
- Cleaning up existing hazardous waste superfund
program - 400,000 waste sites
- Leaking chemical storage tanks and drums (right)
- Pesticides dumps
- Piles of mining wastes
- Must be cleaned up
44Love Canal
- First site of its kind. Sparked CERCLA.
- (aka Superfund)

46Management of Hazardous Waste
- Superfund National Priorities List
- 2006 1558 sites on the list
- States with the greatest number of sites
- New Jersey (115)
- California (93)
- Pennsylvania (93)
- New York (86)
- Michigan (65)
47Superfund What is it?
- Superfund is the name given to the environmental
program established to address abandoned
hazardous waste sites. It is also the name of the
fund established by the Comprehensive
Environmental Response, Compensation and
Liability Act of 1980, as amended (CERCLA
statute, CERCLA overview). This law was enacted
in the wake of the discovery of toxic waste dumps
such as Love Canal and Times Beach in the 1970s.
It allows the EPA to clean up such sites and to
compel responsible parties to perform cleanups or
reimburse the government for EPA-lead cleanups.
48Management of Hazardous Waste
- Biological Treatment of Hazardous Chemicals
- Bioremediation
- Phytoremediation
- Management the Waste we are Producing Now
- (1) source reduction
- (2) conversion to less hazardous materials
- (3) long-term storage
49Management of Hazardous Waste
50Environmental Justice
- Environmental Justice and Ethical Issues
- Right of every citizen, regardless of age, race,
gender, social class, to adequate protection from
environmental hazards - Fundamental human right
- Grassroots campaign
- Mandating environmental Justice- Federal
Level-Clinton 1994, 1997 case in LA, nuke
facility(Ur processing plant)
51Environmental Justice
- International Waste Management
- Developed countries sometimes send their waste to
developing countries - Less expensive than following laws within the
country - Controversial aspect of waste management
- Basel Convention (1989)
- Restricts international transport of hazardous
waste
