TL;DR: The results showed that the higher the enzyme concentration, the more accentuated was the inhibition of methane production and the process was able to recover from the inhibition.

TL;DR: The performance of an anaerobic digestion process is much dependent on the type and the composition of the material to be digested, and when the fraction of starch-rich waste was increased, the result was a more sensitive process, with process overload occurring at a lower organic loading rate (OLR).

TL;DR: In this paper, different policies and policy instruments, as well as other factors, which influence a potential expansion of Swedish biogas systems, are identified and evaluated, and the existing incentives and barriers can be divided into those affecting the production of Biogas, and those affecting its utilisation.

TL;DR: The degradation and biogas production potential of sisal fiber waste could be significantly increased by pre-treatment for reduction of particle size as mentioned in this paper, and the results confirmed that methane yield was inversely proportional to particle size.

TL;DR: The roles of the diverse populations of micro‐organisms responsible for biodegradation of organic matter to form methane and carbon dioxide are rudimentarily understood and links between microbial communities and the rate limiting, hydrolytic stage of two‐stage biogas production from energy crops are expanded.
