Microbiology of the biogas process

Last changed: 16 April 2021

Biogas is produced through degradation of organic material in complex microbial processes. We aim to find solutions for optimised gas production with higher yields and improved process stability.

This occurs both in natural systems and during controlled degradation in bioreactors. Methane is a strong geenhouse gas and thus the production is unwanted in natural environments. However, the biogas technology offers a unique possibility to deal with several environmental issues, i.e. waste treatment, energy production and nutrient recycling. Yet, to obtain an efficient use in practice several issues still remains to be solved.

An optimised biogas production with higher yields

Our goal is to understand correlations between microbiology and methane production. We aim to find solutions for optimised gas production with higher yields and improved process stability in biogas reactors and strategies for reduced methane formation in natural environments. We combine research in both the research laboratory and in industrial biogas processes as well as stydy methane formation processes in natural environments, such as the cow rumen, soil and sediments.

Research in close collaboration with industry

The research is performed in cooperation with national and international universities, as well as with industry and branch oriented organisations

Contact us if you are interested in discussing biogas issues or would like to be a partner in a biogas project. We are also engaged in seminars and courses and can assist in process evaluations and analyses.

Read more about our biogas projects here: (link to webpage).

More information about our collaboration partners is available here (link to webpage).

You can also find information about our activities on the Biogas blogg (in Swedish).

Facts:

At SLU we work with the whole biogas chain. An unique feature for our research is that we answer questions about both energy generation and waste treatment. We have our own biogas plant as well as top modern laboratories.
