Abstract

Gamping biogas plant was built in 2011 to solve waste problem from GemahRipah fruit market which generate 4-10 tons waste/day. The digester was design for 4 ton/day and produce biogas and electricity. The electricity is used for lighting the shops and the road. For eightyears along the installation, biogas unit has been facilitated with transportation, crusher, anaerobic digester, generator, electricity and sensor unit. All the facilities are purposedto utilize the biogas. Another side product of sludge from digestate as by product is just discharged without any application. Here, we developed zero waste concept to utilize all products of anaerobic digester i.e. biogas to produce electricity and biogas sludge as fertilizer. The liquid fertilizer potentially supports the sustainability of the biogas unit from economic value of vegetable products or liquid fertilizer itself. Biogas produced from fruit waste contains 59% methane and 37% carbon dioxide (average from one year). The cumulative production for a half year monitoring is 650 Nm3 biogas and generate electricity up to 120 kWh. Biogas slurry effluent was fermented for two weeks and directly appliedas fertilizer. The analysis showed it contains C-Organik, N Total, P, K 0.39%, 0.34%, 0.07%, 1.91% respectively. Biogas slurry could support the growth of vegetative phase, while less support for generative phase.
