Track: Energy and Resource Efficiency
Abstract
Landfills are increasingly becoming an attractive source for gas generation, a renewable source of energy that can be used for heating and cooking purposes at both household and industrial level. In this study, a variety of landfill waste with a capacity to generate biogas with 60% bio methane composition was studied for potential bio methane (CH4) enrichment. Physical and chemical absorption, membrane separation and cryogenic separation were studied as the bio methane enrichment methane. The methods were ranked in terms of product purity, ease of use and adaptability and the adsorption and membrane separation methods were superior. However, chemical absorbed was then chosen as the bio methane enrichment method due to its low energy requirements of 0.6-1.9 CH4 percentage of total amount of CH4 required for heating.
