Mushroom is a good source of protein, vitamins and minerals and is known to have a
broad range of uses as food and medicine. However, the production of mushroom in
Malaysia is still below the demand required. Spent mushroom substrate (SMS) is one
of the major waste produced which caused disposal problem. This study was
performed to produce biochar from SMS using microwave pyrolysis technique under
different repetition time of carbonisation process and then the biochar was used as
bio-char based fertilizer for mushroom cultivation. BioC 3 was the best quality biochar
produced with high carbon content which is 66 wt% and zero sulphur content.
Cultivating the mushroom with BioC 3 achieved faster mycelium growth rate by
increasing 30%. Therefore, BioC 3 can be a promising fertilizer to boost up the
mushroom cultivation.
