The present paper reports biogas production from biologically pretreated paddy straw in a solid state digester made of HDPE plastic (124 litre capacity). The trial was conducted with a mixture of 10 kg pretreated paddy straw, 20 kg cattle dung slurry, 20 kg cattle dung and 20 litre water. The chemical and proximate analysis of the feed was done and biogas production profile was studied over a period of one month. Parallel trial was also conducted with untreated paddy straw. The result indicated that 253.89 litre biogas/kg pretreated paddy straw was produced, which is 39.3% higher than the untreated paddy straw.
Fabricated digester worked well for biogas generation from untreatedas well as pretreated paddy straw.
39.3% enhancement in biogas production was observed in case of pretreated straw.
