1. Solid Waste Pollution Risk and the Population

2. Solid Waste Pollution  Solid Waste  Any unwanted or discarded material that is not a liquid or gas.

3. Solid Waste Pollution  Numbers to look for...  4.6  33  75

4. Solid Waste Pollution  Solid Waste Producers in the U.S.  11 metric tons of solid waste are produced each year in the U.S.

5. Solid Waste Pollution  Municipal Solid Waste (MSW)  MSW—more commonly known as trash or garbage—consists of everyday items  Product packaging  Grass clippings  Furniture  Clothing  Bottles  Food scraps  Newspapers  Appliances  Paint  Batteries

15. Solid Waste Pollution  Hazardous Solid Waste

16. Solid Waste Pollution  Dealing With Hazardous Solid Waste  Physical methods: allow particles to settle and be filtered out  Phytoremediation: using plants to absorb, filter, and remove contaminants. May need to genetically modify plants  Plasma Arc Torch: extremely high temps to break down toxic waste into ions/atoms  Deep-well disposal: pumping liquid hazard waste deep underground  Surface impoundment: use of ponds, pits, or lagoons. Water evaporates, toxins stay.
