摘要

The author, developer of the only water or wastewater technology to win the coveted President's Citation of Excellence in Environmental and Conservation Technology, identifies the major national and international problems asociated with the management of over 10,000,000,000 (ten billion) wt of organic wastes annually generated in the USA alone. Pulp and paper, food process, and animal manures are the primary sources of these huge organic waste stremas. The problems discussed in detail include significant, if not critical, public concern over pathogens in animal manures (over 2,000,000,000 wet tons), non-point source water pollution, and unregualted methane, CO_2, nitrous oxides, and hydrocarbon emissions exceeding 20 trillion cubic feet per year from organic landifills, lagoons, and surface impoundments. These gases exceed the emissions from the entire transportation industry of the United States.
