摘要

A field study using low technology composting methods was evaluated. Numerous feedstocks including food waste containing chicken offal and sheep heads, manure, yard debris and sawdust were used. The technologies evaluated were a limited turned windrow (LTW) and a passively aerated windrow (PAW). Full scale field windrows or piles were constructed during two seasons involving wet and dry seasons. High temperatures exceeding 55°C (131°F) were achieved for both technologies during the two seasons. This resulted in pathogen destruction which met both the State of Oregon and the United States Environmental Protection Agency regulations for control of pathogens and vector attraction reduction. Both methods achieved product stability and maturity within a 14 week period. With the feedstocks used, product characteristics met regulatory requirements for heavy metals and other criteria. The results of the study indicated that the PAW method can have important implications for managing contaminated wastes in developing countries because it is economical and easily implemented.
