Silkworm waste management in biogas production

In time of waste utilization problems, sericulture focuses not only on the cocoon production, but also on other ways that can
benefit the farm’s economy and help with environmental protection. It is necessary to find new sources of income for farmers
not only through cocoon selling, but also by the multiple uses of by-products. Insect farming technology provides a cheap
source of biomass, which may be a good material in biogas production. Studies showed that the substrates, both silkworm
breeding waste and caterpillar excreta, generate a biogas yield similar to other substrates of agricultural origin, such as animal
manure. Fermentation of silkworm excreta under mesophilic conditions produces 167.32 m3/Mg TS of methane and 331.97
m3/Mg TS of biogas, while fermentation of silkworm breeding waste yields 256.59 m3/Mg TS of methane and 489.24 m3/Mg
TS of biogas. Presentation shows a part of an extensive research project concerning management of products and by-products
obtained from sericulture. The presented study allows investors and farmers to easily estimate the amount of electricity and
heat offered by the available substrate.
