BMP (biochemical methane potential) is the amount of methane that can be obtained from a unit of organic mass of a substrate in a batch test. We compile the results of many publications for each substrate, calculate a weighted mean and show all the curves at once.

Researchers from Jiangxi Agricultural University increased the methane yield from the co-digestion of rice straw and pig slurry by about 45% through biological pretreatment with a cellulolytic microflora.
A team from the Jiangsu Academy of Agricultural Sciences in Nanjing compared three chemical agents for pretreating rice straw. Slaked lime gave 413.5 mL of biogas/g VS — 45% more than untreated straw — after 72 hours of treatment.
