Term
Law of Conservation of matter:
Definition
states that matter is never created or destroyed
Term
Biodegradable:
Definition
waste that can be broken down by microbes
Term
Open Dumps:
Definition
places where trash-both hazardous and nonhazardous-is simply piled up
Term
Leachate:
Definition
water that carries dissolved sustances (often contaminated) that can percolate through soil
Term
Incinerators:
Definition
Facilities that burn trash at high temperatures
Term
E-waste:
Definition
Unwanted computers and other electronic devices such as televisions and cell phones that are discarded
Term
Composting:
Definition
Providing good conditions for the decomposition of biodegradable waste providing a soil-like mulch
Term
Refuse:
Definition
Choose NOT to use or buy a product if you can do without it
Term
Reduce:
Definition
Make choices that allow you to use less of a resource by, for instance, purchasing durable goods that will last or can be repaired
Term
Reuse:
Definition
Use a product more than once for its original purpose or another purpose
Term
Law of conservation of matter
Definition
Matter can neither be created nor destroyed; it only changes form.
Term
Waste
Definition
Any material that humans deem to be unwanted.
Term
Biodegradable
Definition
capable of being broken down by living organims.
Term
Nondegradable
Definition
incapable of being broken down undernormal conditions.
Term
Municipal soild waste(MSW)
Definition
everyday garbage or trash(soild waste) produced by individuals or small businesses.
Term
Open dumps
Definition
places where trash, bothhazardous and nonhazardous, is simply piled up.
Term
Hazardous Waste
Definition
waste that is toxic, flammable, corrosive, explosive, or radioactive.
Term
Leachate
Definition
wtaer that carries dissolved substances(often contaminated) that can percolate through soil.
Term
Incinerators
Definition
Facilities that burn trash at high temperatures.
Term
Composting
Definition
providing good conditions for the decomposition of biodegradable waste, producing a soil-like mulch.
Term
Eco-industrial parks
Definition
industrial parks in which industries are physically positioned near each other for "waste-to-feed" exchanges(the waste of one becomes the raw materials for another).
Term
Refuse
Definition
The first of the waste-reduction "4 R's": Choose NOT to use or buy a product if you can do without it.
Term
Reduce
Definition
The second of the waste-reduction "4 R's": Make choices that allow you to use less of a resource by, for intance, purchasing durable goods that will last or can be repaired
Term
Reuse
Definition
The third of the waste-reduction "4 R's": Use a product more than once for its original purpose or another purpose
Term
Recycle
Definition
The fourth of the waste-reduction "4 R's": reprocessing items to make new products.
Term
Composting
Definition
Allowing waste to biologically decompose in the presence of oxygen and water (can turn some trash into soil)
Term
Biodegradeable
Definition
Waste that can be broken down by microbes and that can be broken down by chemical and phsyical reactions
Term
Nondegradeable
Definition
Molecules that are chemically stable and don't degrade in normal atmospheric conditions
Term
Municipal Solid Waste
Definition
Act of living in houses, apts, dorms, and small businesses-produces its own stream of trash
Term
Open Dumps
Definition
Are places where both hazardous and non-hazardous trash is simply piled up (common in undeveloped countires)
Term
Leachate
Definition
Rain water that washes pollutants away from the dump into surrounding areas or soaks it into the ground (contaminated water)
Term
Sanitary Landfills
Definition
Seal in trash at the top and botton in an attempt to prevent its release into the environment ( more common in developed countries)
Term
Incinerators
Definition
Trash is burned in a combustion chamber, which reduces its volume by 80-90%, but pollutes air and water (extremely expensive)
Term
E-waste
Definition
Refers to old electronic devices, such as, phones, computers, and televisions
Term
Eco-Industrial Parks
Definition
Where industries are positioned so that they can use each other's waste in the same industrial area
Term
Law of Conservation of Matter
Definition
When matter expelled by one organism is taken up by another organism and used again. States that matter is never created nor destroyed; it only changes form. Humans disrupt this by taking matter out of reach of organisms that can use it.
Term
MSW Stream
Definition
In the U.S., we produce about 243 million tons of household trash per year - twice the per capita amount produced by the European Union and 10 times the amount produced by developing countries. Majority of trash comes from paper, wood, glass, rubber, plastic,etc
Term
Growing Atlantic Garbage Patch
Definition
First garbage patch was discovered in 1997 by Capt. Charles Moore. It was hard to determine the size of the patch and whether it was growing or not. Plastic being ingested by sea birds doubled from 1975-1985. Plastic is being mixed into the water column, not surface.
Term
Improper Municipal Waste Disposal
Definition
When disposed improperly, chemical waste is deterimental to plant and animal life. Aquatic life is very vulnerable. Sea mammals get tangled in sex-pack rings, swallow plastic, and die from toxins. BPA (in plastic) carcinogen. Plastic also absorbs pollutants (PCBs & DDT) which accumulate in tissures of mariane organisms and move up food chain.interferes with reproductive systems and is a suspected
Term
Reducing Waste - Best Solutions
Definition
Use composting on a large scale for organic wastes. Convert garbage into usable energy (ex. Heat produced during incineration-convert into steam energy/electricity). Use of eco-industrial parks. Refuse, reduce, reuse, and recycle. All are ways to reduce waste in the U.S.
