“…Some of these possibilities are not feasible (e.g. animal feed) (Adamovi c et al, 1998), others are demanding or difficult to implement (Finney et al, 2009), and the rest are still subject of research at present. None of them have been applied in the industry yet.…”

“…Pyrolytic conversion to fuel and chemicals is, therefore, an attractive alternative for recycling the spent mushroom beds. Spent mushroom substrates have been shown to be a good feedstock for gasification because they have high-energy content similar to that of fuel wood [29][30][31]. Williams et al also reported that spent mushroom beds have potential as an energy feedstock with a high caloric value [32].…”

To evaluate spent mushroom beds (log and sawdust beds) as a two-step gasification resource, carbonization of spent mushroom beds for the production of char and gasification of the chars were performed using a small laboratory system. Carbonization of the mushroom beds at 600 °C produced suitable chars as the source for steam gasification. In addition, the wood gas produced during the carbonization process had a sufficient higher heating value and thus could be used as the fuel for the gasification step. The gasification of the spent bed chars produced clean hydrogen-rich gases without generation of any by-products. On the other hand, direct gasification of a waste log bed generated hydrocarbon and tar-like materials. Furthermore, the water-gas reaction (C + H2O → CO + H2) was proposed as the mechanism for the gasification process.

“…Most of the SMS in China is burnt for energy, which is neither environmentally-friendly nor economically optimal (Zhu et al 2013). It is estimated that the combustion of SMS produces ash of more than 10% of its original volume (Finney et al 2009). …”

“…Spent mushroom substrate can be used as an organic agricultural fertilizer, but the high content of mineral salts limits its use for the fertilization of salt-sensitive plants. Further, leaching of SMS can seriously endanger local water supplies (Finney et al 2009). …”

a Chars were obtained from spent mushroom substrate (SMS) via pyrolysis. It was found that as the pyrolysis temperature increased from 400 to 700 °C, the char yield decreased from 45.10 to 33.79 wt.% and the higher heating value increased from 17.32 to 22.72 MJ/kg. The largest BET surface area (13 m 2 /g) was created at 500 °C. Hydrogen atoms were continuously lost during pyrolysis, whereas oxygen atoms were difficult to eliminate. Whewellite, calcite, lime, and quartz were the minerals in the chars, and their forms and crystallinity changed with changing pyrolysis temperature. Activated carbon with a BET surface area of 1023 m 2 /g and a total pore volume of 0.595 cm 3 /g was obtained from the char prepared at 500 °C. Its characteristics were studied by N2-adsorption, Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The pyrolysis and KOH-activation processes were investigated by thermogravimetric analysis (TGA). The results showed that the pyrolysis of SMS occurred primarily between 217 and 375 °C and that the energies needed for the pyrolysis reactions were relatively low due to the prior mushroom cultivation. Furthermore, lignin was incompletely decomposed in the char prepared at 500 °C, and KOH suppressed tar evolution and reduced the energy needed to decompose the residual lignin during activation.
