by humans – us as individuals.Technically we might better define garbage as Solid

Waste - the totality of all materials thrown away from homes and commercial establishments and usually collected by some process for "disposal"

Where is Away?

Where is away?

• Prior to 1975 = open dumps• 1975-1981 SLF's and ocean dumping• 1980-1990 Incineration• 1990 - the dawn of recycling• 1991 EPA ruling 1/2 of all 6000 US SLFs

closed by 1995– no wetland slfs– must monitor surface and ground water

effluents– must install liners and leachate collection

systems– must monitor for 30 years after closing

Where is away?• Resource

Recovery– RDF– Minnesota's

waste-to-energy plants produce enough energy to heat over 90,000 homes each day.

Minnesota's resource recovery plants have conserved over 39 million cubic yards of landfill space.http://www.moea.state.mn.us/policy/policy1999_Q&A.cfm

Where is away?• Resource

Recovery– Curbside

Recycling

• Recycling in Minnesota has created new industries and economic development, creating more than 8,000 direct jobs in recycled products manufacturing alone.• Meeting the goal of landfilling no unprocessed waste by 2008 will reduce sulfur dioxide emissions by 340,000 tons, save 1,000 acres from being developed as landfill, and substantially reduce Minnesota's greenhouse gas emissions.http://www.moea.state.mn.us/policy/policy1999_Q&A.cfm

Amounts of Chemicals Entering the Environment For 2001:

1,679 million pounds of toxic chemicals released to the air

221 million pounds of toxic chemicals released to the water

4,258 million pounds of toxic chemicals released at land disposal sites

Total environmental release = 6,158 million pounds

Fate of Chemicals Entering the Environment

Many are broken down by natural processes Two types persist in the environment

Heavy metals– Lead, mercury, arsenic, cadmium, tin, chromium, zinc, copper– Used in metalworking, paint, and pesticides, among other products– Soluble in water and readily absorbed by body– Interfere with enzyme function– Example: mental retardation from mercury poisoning - Minamata Disease– Fish in MN - mercury and PCBs - http://www.health.state.mn.us/divs/eh/fish/ Synthetic organics– Chemical basis for plastics, synthetic fibers and rubber, solvents, and pesticides– Halogenated hydrocarbons

• At least one of the hydrogen atoms is replaced with a halogen atom– Chlorine (most common)– Bromine– Fluorine– IodineResistant to biodegradation

– Major health effects: carcinogenic and mutagenic

Preventing Chemicals from Entering the Environment

Disposal Shallow - Times Beach, MO - waste oil to control road dust [EPA press release - February 22, 1983] In a joint federal-state action, the Environmental Protection Agency (EPA), the

Federal Emergency Management Agency (FEMA), and the State of Missouri announced today that resources have been allocated for the permanent relocation of residents of Times Beach, Missouri. The action was necessary after the Centers for Disease Control (CDC) completed analysis of extensive soil sampling in the area and advised that the hazard posed by dioxin contamination is a continuing threat to the health of citizens in the community.
