Analysis and Processing of Kitchen waste using portable Bio-Methanation Digester

ABSTRACT Biogas technology can be sustainable and cost effective in the long run. It is beneficial to the households for safe and smoke-free combustion for cooking in households. This project is concerned with designing a domestic facility that will treat kitchen waste to produce biogas. This biogas produced will be devoid, to very large extent of harmful bi products of anaerobic digestion. This system will use starchy or sugary feedstock waste grain flour, spoilt grain, over ripe or misshapen fruit, non-edible seeds, fruits and rhizomes, leftover food, etc. Two kilograms of such feedstock produces about 500g of methane and the reaction is completed within 24 hours. The process can be more efficient by adding 10kg of cattle dung and approximately 300 Kgs of methane gas can be produced. This is far more efficient than the conventional biogas system.
