A study of biogas generation from coconut pith

Abstract

Biogas production from cowdung is well studied. Coconut pith is an agricultural waste available in large quantities in Kerala: the possibility of using coconut pith for biogas production was studied. It was found that coconut pith in combination with cowdung gives considerable amount of biogas, while alone it did not produce any gas. The optimum combination was found to be 60% pith and 40% cowdung.Study of dilution effect on the slurry showed that the optimum solid-liquid ratio is 1 : 20. Partial removal of lignin from pith increased the rate of biogas production. Gas produced from a mixture of cowdung and pith was found to have a higher methane content than that produced from cowdung only.

A Novel Method for Accelerated Composting of Coir Pith

“…It is essentially a ligno-cellulosic material that decomposes very slowly in soil, because its pentosan/lignin ratio is 1:0.30; the minimum required for moderately fast decomposition in the soil is 1:0.50 . It has been reported that coir pith in combination with cow dung gives a considerable amount of biogas . About 7.5 × 10 5 tons of coir pith is produced annually in India .…”

Efficient utilization of xylanase and lipase producing thermophilic marine actinomycetes (Streptomyces albus and Streptomyces hygroscopicus) in the production of ecofriendly alternative energy from waste

“…The energy from biomass holds a promising scope under Indian conditions because this sector encourages the efficient management of agricultural waste in an eco-friendly way (Stalin et al, 2012). Biogas production was observed from codigestion of cow dung with rice husk, coconut pith and rice chaff (Elijah et al, 2009;Radhika et al, 1983;Vivekanandan and Kamaraj, 2011).…”
