Abstract

A good start-up of digestion of tomato-processing waste (TP W) was achieved by the stepwise addition of feedstock over 10-12 weeks of digestion. The stepped increases of TP W in the digester resulted in a steady-state gas yield of 0.597m3/kg VS added with a 72% methane content. Volumetric production of gas and methane remained high after the eighth week of digestion throughout the investigation. The volatile fatty acids concentration in this system was similar to a cowdung-fed digester and never exceeded more than 150mg/litre throughout the period
