Environmental Science, Donald Winslow 4 December 2009 Solid & hazardous materials
Mining • Minerals & rock • Economic geology • 1872 Mining law • Metals • Non-metal mineral resources • Fuel • Environmental effects of mining • Reducing consumption
Al, Fe, Cu, Pb, Ni, Zn, Hg, Sn, Cr, Mn, Pt, Au, Ag Metals refined from mined ore
Non-metal mineral resources • Gravel • Clay • Glass • Salts
Fuel • Uranium • Petroleum • Coal • Mountaintop Removal • www.ilovemountains.org • Natural gas • Coal-bed methane • Powder River, Wyoming • Arkoma Basin, Oklahoma
Environmental effects of mining • Acid drainage • Processing • Smelting • Heap-leach extraction
Reducing consumption • Metals • Plastics • Fuels • Electricity • etc Eliminating unnecessary consumption reduces waste.
What is waste? Solid and hazardous waste
Solid “waste” • “Waste” production • American waste stream • Fate of American solid materials • Landfills closing • Reduce, reuse, recycle • Hazardous waste
American waste stream • Paper & paperboard • Yard trimmings • Plastic • Food • Metals
Fate of American solid materials • Landfills • Open dumps • Sanitary landfills • Ocean dumping • Exporting waste & environmental justice • Recycling • Incineration • Composting
Recycling • Sorting, cleaning, reformulating • Demanufacturing • Biodegradable plastics
Incineration • Pollution • Cogeneration
Hazardous waste • Chemical & petroleum pollution • Federal legislation & regulation • Cradle-to-grave • Superfund • Electrical transformers & PCBs • Brownfields • Bioremediation • Retrievable storage & secure landfills
