Nine volatile hydrocarbons, as well as methyl chloride, carbonyl sulphide and carbon disulphide, have been identified by mass spectrometry as products of Agaricus bisporus in the compost used in comerical mushroom beds. Of these, only ethylene showed a pattern of production that could be correlated with developmental phases of the crop, high levels being produced whenever fruit bodies were rapi...

Passive leaching by rainfall and snowmelt is a popular method to treat piles of spent mushroom substrate (SMS) before its reuse. During this field weathering process, leachate percolates into the underlying soils. A field study was conducted to examine the chemistry of SMS leachate and effects of infiltration. Two SMS piles were deposited (90 and 150 cm in height) over a Typic Hapludult and wea...

The quantity of biogas residues is continually increasing and causing a great threat to the environmental protection sustainable development bio-natural gas engineering. Thus, four (sewage sludge, SR; spent mushroom compost, MR; wheat straw, STR; distillers’ grains, DL) were collected prepare biochars at different temperatures (300 °C, 500 700 °C) in this study. functional groups, crystal struc...
