Document Summary
Geology and the environment lecture march 21, 2016. Three different areas of activity related to waste disposal. Fluid industrial wastes: putting them deep in pore holes. Picture: open dump where all kinds of waste have just been deposited. Chemical wastes from industry and agriculture: soluble organics, toxic materials, hydrocarbons. Lots of waste from making these: manure, fertilizers, herbicides, pesticides. Wide range of inorganic and toxic materials. Heat: waste energy as heat released into environment, for example, when we dispose of used cooling water. Radioactive wastes: radioactive wastes related to medicine, various lab research, there are radioactive wastes in waste-rock from uranium mining operations. City dump: residential/commercial/industrial wastes, takes in residential, commercial, and industrial waste, very bad for us. Recycling of wastes: done on a local scale, recycling as a city. Biogas gas for heating and lighting purposes. Usually in rural setting, extracted from human and animal excrement. Municipal wastes are being increasingly subjected to this type of approach.
