How to Make Bio Gas From Paddy Straw


The project proposes a simple and low-cost biotechnological process (RSTM process; see 9.2) for the conversion of waste rice straw into biogas.


It is proposed that microbial fermentation of waste rice straw could become a significant supplementary energy source in rice producing regions in Asia. Rice straw is a major agricultural waste product in Asia with an estimated production of approx 700 million tons/year. Currently most of this waste biomass resource is not utilized or recycled in a sustainable manner.
