The utilization of vegetal wastes such as stalks, straw, bran
and molasses generated during the agricultural product
harvest and industrial processing in the agricultural
production again is an environmental approach (Akyüz
and Kırbağ 2009). One of the wastes to be utilized is
spent mushroom compost released during fungi culture.
2.5-3 kilos of wastes which cannot be used in mushroom
production again remain from the production of 1 kilo of
cultivated mushroom. Although fungi culture has a short
past in Turkey, the amount of the mushrooms produced
is increasing every year. According to the data in 2008, this
amount is 26.526 ton
