| solid waste | any discarded material that is not a liquid of a gas |
| hazardous waste | wastes that are toxic or highly corrosive or that explode easily |
| synthetic fertilizer | fertilizer produced in factories and used in place of manure and plant wastes |
| incinerator | plant used for burning solid waste material |
| methane | colorless, odorless, flammable gas present in natural gas and formed by the decompostion of plant matter |
| leachate | water that contains toxic chemicals dissolved from wastes in a landfill |
| surface impoundment | a pond with a sealed bottom that serves a disposal facility in which wastes settle to the bottom |
| Name three things that are biodegradable | paper bags, leather, cotton fiber, newspaper |

| Superfund act | it gives epa the right to sue owners of hazardous waste sites to make them pay for the cleanup and creates a fund for cleaning abandoned haz. wast. sites |
| degradable plastics | photo degradable plastic breaks down really small but does not disappear, trying to create real biodegra. plastics |
| how much energy is used to make new aluminum cans from old aluminums cans | 95% less energy then making one from ORE |
| 3 prob. associated w/ modern landfills | not enough space, does not degrade, leachate, methane |
| how can the gov. help reduce hazardous waste production | produceless ,reuse, convert into non hazardous, insenerate (most $$$) land desposal |
| name one way not to manage hazardous waste | put it down the drain |
| name one disadvantage of building a landfill near a city | pollution from landfill, makes people sick |
