The public lecture on biogas as a practical and sustainable alternative energy source for domestic applications was held via Zoom on 25th August 2022 by Eng Kalpa Welivitigoda


Energy is a critical factor in the uninterrupted continuation of human life on a global scale. With the rapid depletion of fossil fuels, the world continues to try to move away from petroleum-based fuels. In the Sri Lankan context, in the domestic sector, liquid petroleum gas (LPG) is heavily used, in particular for cooking.

With the recent shortage of LPG in the country, Sri Lankans have looked for alternative energy sources, and biogas is one of them. There has been a boom of interest in the subject in terms of awareness, knowledge sharing, construction of units, etc. While sharing general knowledge on biogas as a fuel, this talk discusses more on the practical aspects of a do-it-yourself domestic biogas unit.
