What is it about?

In this work, an approach has been executed in converting waste into energy and utilizing the obtained energy into useful applications. we have extracted the biogas from waste food collected from various hotels in the city. using a floating type dome digester, the biogas is generated and it is used as an alternative fuel for diesel engine operated by dual-fuel mode. biogas is inducted into the engine with different mass flow rates rangine from BG20 to BG60 and mixing with air.The experimental results reveal that less power was developed after using the biogas, on the other hand, lower-emission was observed which is concluded that biogas is a best renewable fuel.

Why is it important?

Atmospheric pollution from the green house gases and disposal of various waste sources are causing tremendous effect on human beings and other creatures in the planet earth. Extracting the energy and utilizing it into some useful applications can mitigate the effect of green house gases and waste energy sources. Biogas is one such renewable energy which is obtained by the anaerobic digestion process of waste resources and can be used as an alternative fuel for operating internal combustion engines. The objective of the present work is to investigate the performance, combustion and emission characteristics of diesel engine using methane-enriched biogas operated by dual fuel mode.


This article provides detailed outcomes of the extraction of biogas from food waste and utilizing the methane enriched biogas in the diesel engine as an alternative fuel operated in dual fuel mode. This research will motivate other researchers who are working in renewable energy to find out the various aspects associated with the in and out of the biogas utilization in transportation and other sectors. From my perspective, it provides a solution for the depletion of fossil fuels, with greenhouse gas emissions, mitigation of waste disposal and to meet the power requirement for the industries across the world.
