What is it about?
Crop residues have the potential to enter the feeds stock stream for biogas production. However, they have limited utility because they are hard to digest. Pre-treatment is an alternative method to enhance digestibility a and biogas production from crop residues. We provided a systematic aggregated comparison of different pre-treatment methods to improve biogas yield. We found that biological pre-treatment is the best option though there is need to improve on its efficacy. Physical and chemical methods are expensive due to high energy and operational costs, and also produce inhibitory compounds.

Why is it important?
It gives an insight on selection of the best pre-treatment to use.
Perspectives
Writing this article was a great pleasure as it has a co-author with whom I have had long standing collaborations. I also dedicate it to one of the co-authors who passed on during the preparatory stages of the article. This article lead to biofuel research, and in particular biogas research groups. Biogas has the potential to improve the livelihoods of rural pro-poor people in developing countries.
