Quality assessment of compost prepared from spent mushroom substrate

The human demand for protein-rich food is everincreasing which contributes to the expansion of mushroom industry in the world. Statistically, the word production of mushroom industry has reached a level greater than 25 million tons (Yang et al., 2015). In spite of many advantages, the production of mushrooms generates large volumes of solid waste products (called spent mushroom substrate) which constitute one of the most significant environmental issues for the mushroom industry (Topas et al., 2014) as about 5 kg of waste substrates are generated from the production of 1 kg of mushrooms (Medina et al., 2012).
