Daftar Isi:
- Lignocellulosic wastes such as rubber wood saw dust, bagasse, cayuput oil waste, municipal solid waste, vegetable waste were digested by solid state fermentation at Thermophillic temperature (55°C), and dry matter condition of 20-40Percent in 25 liter anaerobic fermentors.All of the lignocellulosic wastes, except for cayuput oil waste can be digested. The result revealed that the biogas productivity is about 1.66.5 V/V.r.d, methane content about 48.853.3 percent, retention time about 1334 days and efficiency of conversion about 12-61 percent.Solid state fermentation at the above mentioned conditions increases the biogas productivity of about 2-6 times more than that of the conventional method.Solid state fermentation of a mixture of rubber wood saw dust and water hyacinth (ratio 90/10) revealed that bioga» productivity was the lowest, retention time appeared to be the longest and the efficiency of conversion was relatively low (15%),, On the other hand, solid state fermentation of fresh municipal solid waste gave the highest productivity of about 6.5 V/V,r,d, relatively short retention time (16.6 days) and high efficiency of about 57%. Solid state fermentation of mixture of rice straw and water hyacinth (95/5) and also of the municipal solid waste, rubber wood saw dust, bagasse and water hya- cinth (68/ 15/ 1214) gave a high productivity and efficiency.
