Food, Fuel, and Fertilizer from Organic Wastes

摘要

This report examines some of the opportunities for the utilization of organic wastes and residues commonly found in the poorer rural areas of the world. It is based on discussions and presentations at a panel meeting of the Advisory Committee on Technology Innovation held on 6-8 August, 1979, in Airlie, Virginia, USA. The purpose is to set forth in array of alternatives for possible application where existing waste usage (or nonusage) is no longer appropriate. The processes described range from simple and inexpensive techniques to those more complex and costly. Many are already in use in rural areas, but some are still being developed at universities and research institutes. Although there are some generalizations on economic factors, projections of operating and capital costs in vastly different environments are impossible. Most of the processes described are both labor intensive and site sensitive.
