Co-digestion of municipal solid waste with lignocellulosic waste in mesophilic Environment.

The present study deals with the dual problem of municipal solid waste and lignocellulosic waste in which authors tried to use these two waste materials as clean and renewable energy source. In the present study, anaerobic digestion of organic fraction of municipal solid waste and lignocellulosic waste in varying combinations was carried out. Five-set of experiments (S1, S2, S3, S4, and S5) under mesophilic conditions were conducted in batch reactors.

Effect of bulking agents and cow dung as inoculant on vegetable waste compost quality.

The source segregated vegetable waste (VW) was used as main feedstock and locally available organic wastes, such as water hyacinth (WH), garden prune (GP) and sawdust (SD) were used as bulking agents (BAs) to make the compost stable and mature in combination with cow dung (CD) as a source of inoculant. Three trials (T, T & T) were performed with a compost ratio of 6:3:1 (VW:BA:CD) using different BAs. The initial C/N ratio of all the trials was maintained lesser than 23 and composted for 30 days (7 days in rotary drum reactor + 23 days windrowing).
