BMP testing — substrate methane potential — page 13
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.

Chinese research on rice straw: chemical pretreatment raises biogas yield by 36–45%
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.
