Study of effective auxiliary material for promoting fermentation and suppression of odour during composting
2017
Futagawa, Y. | Akitomo, I.
In a composting test using the dung of pig, rice husk charcoal, rice bran, and sawdust were used as auxiliary materials. Waste glycerin was used for promoting the fermentation. Pig dung was tested for composting by adding these materials to investigate the effects on the fermentation conditions and reducing the odour. Rice bran did not reduce the odours and did not promote fermentation. Waste glycerin fermentation with added 5% by weight ratio did promote fermentation. The generation of ammonia was suppressed by adding rice husk charcoal. In the winter, fermentation of compost was promoted by adding waste glycerin and rice husk charcoal. Ammonia concentration of the odour was also lower.
