Highlights

Recent R&D works for biogas and anaerobic digestion process were reviewed.

Substrates, reactors, treatments, operation and system analysis were covered.

Research focuses and ways forward for AD process were discussed.

Abstract

Anaerobic digestion (AD) is a biological process that can convert organic substrates to biogas in the absence of oxygen. The AD process has been practiced for centuries; however, it is still a research focus in contemporary literature. This mini-review selected papers published in 2015 and summarized the improvement and technological advancement and revealing current research and development trends for the biogas from AD process. A discussion on the challenges and prospects for developing improved AD technologies is provided.
