Abstract

A heat and caustic pretreatment process has been tested to determine the increase in gas yield that can be obtained from fermentation of organic municipal refuse. A treatment temperature of 130°C and a NaOH concentration of 3 g/100 g of dry solids resulted in the highest gas yield for the conditions tested. The probable increase in gas yield was 20% for the best conditions tested. The treatment procedure also substantially increased the rates of gas production. A high conversion efficiency is possible at much shorter reactor retention times with pretreatment than without pretreatment.
