APES Chapter 30 Waste Management

e-waste
electronic waste
dilute and disperse
easy disposal of waste (usually from factories) into rivers
concentrate and contain
to concentrate waste and place it into containers for further disposal. caused health hazards due to leaks
10 years
length of time until Los Angeles landfill spaces become full
NIMBY
Not In My Back Yard ; attitude used when no one wants to live near a waste disposal site
zero waste movement
environmentally correct concept to consider wastes as resources out of place
industrial ecology
the study of relationships among industrial systems
integrated waste management (IWM)
basically reduce, reuse, recycle ;
includes reusing, source reduction, recycling, composting, landfill, and incinteration.
waste stream
the waste produced
ways to reduce
• better packaging design
• composting programs
• recycling programs
materials management
sustainable use of materials combined with resource conservation
composting
a biochemical process in which organic materials decompose to rich soil material
incineration
when combustible waste is burned at extremely high temperatures
incineration temperature ranges
900°-1000°C
or
1650°-1830°F
sanitary landfill
designed to concentrate and contian refuse without causing hazard to public health or safety
municipal solid waste landfill
aka sanitary landfill
leachate
garbage juice
site selection of a sanitary landfill
a favorable combination of climatic, hydrologic, and geologic conditions which helps ensure safety
environmental justice
study of social issues in waste facilities, and also the right that everyone gets to have a comfortable place in environment
monitoring
accomplished by periodically taking samples of water and gas from specially designed monitoring wells
how pollutants can enter the environment through sanitary landfills
1. atmosphere

2. retention in soil

3. groundwater

4. surface runoff

5. crops

6. plant residue

7. stream flow

8. wind

qualities of a sanitary landfill :
• have leachate
• site selection
• may have incineration plants
• monitoring
• integrated waste management
hazardous waste
dangerous chemical waste
RCRA
resource conservation and recovery act
“cradle to grave” management
to issue guidelines and responsibilities to those who manufactured, transported, and disposed of hazardous waste
CERCLA
comprehensive environmental response, compensation, and liability act ; established a revolving fund, aka superfund
land application
intentional application of waste materials to the surface soil
surface impoundment
human made depressions and excavations used to hold hazardous liquid waste
deep-well disposal
the injection of waste into deep wells
alternatives to land disposal of hazardous wastes
• source reduction
• recycling
• resource recovery
• treatment
• incineration
north pacific gyre
“garbage island” in between Asia and North America
pollution prevention
• purchasing the proper amount of raw material
• better control of materials in manufacturing
• using nontoxics instead of hazardous materials
• improving design
brownfields
abandoned commercial facilities
Majora Carter
South Bronx
Van Jones
green collar economy
Anne Anderson
A Civil Action
environmental audit
process of determining the past history of a particular site, with special reference to the existence of toxic materials or waste
secure landfill
a type of landfill designed specifically for hazardous waste. Similar to a modern sanitary landfill in that it includes multiple barriers and collection systems to ensure that leachate does not contaminate soil and other resources
