    Abstract

Biogass Generation from Standard China Rubber Processing Effluent
A production test has been carried out for biogass generation from Standard China Rubber (SCR) processing effluent. The results showed that the biogas yield exceeded 1m3/m3.day in the process of fermentation at ambient temperature. It means that about 30 m3 biogas containing 60% of methane can be generated from the effluent (latex-serum) on processing one ton of SCR; heat derived being equivalent to that of about 15 kg fuel oil. This amount accounts for 44% of the heat energy needed for drying one ton of SCR now in China (i.e. heat derived from ca. 35 kg of heavy oil and diesel oil). Biogass generation from SCR processing effluent is feasible technologically and economically, a part of energy needed for drying standard rubber can be saved each year. In addition, the environmental pollution of water by the effluent could be considerably mitigated so as to set up a good foundation for the treatment of SCR processing effluent.
