Solid and Hazardous Waste

1. Managing wastes to limit their environmental harm without trying to reduce the amount of waste produced.
3. Waste disposal site on which waste is spread in thin layers, compacted, and covered with a fresh layer of clay or plastic foam each day.
4. Process in which waste materials are converted into different products.
10. Any discarded material or substance that threatens human health or environment.
14. Solid waste produced by mines, farms, and industries that supply people with goods and services.
16. Variety of coordinated strategies for both waste reduction and waste management designed to deal with the solid wastes human produce.

2. Combined solid wastes produced by households and workplaces other than factories.
5. Form of recycling that mimics nature by using bacteria to decompose yard trimmings, vegetable food scraps, and other biodegradable organic wastes into humus, which is an organic component of soil that improves soil fertility.
6. Using materials again for the same purpose.
7. Storage for liquid hazardous wastes in ponds, pits, or lagoons.
8. Use of natural or genetically engineered plants as "pollution sponges" to absorb, filter, and remove contaminants from polluted soil and water.
9. Reducing the amount of waste produced; wastes that are produced are viewed as potential resources that can be reused, recycled, or composted.
11. Making industrial manufacturing processes cleaner and more sustainable by redesigning them to mimic the way nature deals with wastes.
12. Use of bacteria and enzymes to help destroy toxic or hazardous substances or convert them to harmless compounds.
13. Any unwanted or discarded material people produce that is not a liquid or gas.
15. Pumping of liquid hazardous wastes under high pressure through a pipe into dry, porous rock formations far beneath aquifers that are tapped for drinking and irrigation water.
