Fuel Pelletization with a Binder: Part I — Identification of a Suitable Binder for Spent Mushroom Compost−Coal Tailing Pellets
Energy & Fuels, 2009Co-Authors: Karen N. Finney, Vida N. Sharifi, Jim SwithenbankAbstract:Spent Mushroom Compost and coal tailings are wastes that could be used as energy sources, through combustion in a fluidized-bed. Our previous pelletization studies produced a denser, yet friable fuel, which produced dust on transport, handling, and feeding. Thus, a suitable binder for these materials was required to enhance pellet properties. Inorganic (caustic soda) and organic (starch) binders were selected for a range of tests. Pelletization at elevated temperatures was also assessed to evaluate the softening of any lignin present in the straw component of the Mushroom Compost. Small amounts (up to 1 wt %) of both binders increased pellet tensile strength, where starch had more pronounced impacts, doubling the tensile strength to 411 kPa. Pelletization at elevated temperatures (45−75 °C), however, improved overall pellet quality more significantly, increasing the tensile strength to over 600 kPa, although additional temperature increases (up to 125 °C) did not result in further improvements.

Growth Characteristics of the Thermophilic Fungus Scytalidium thermophilum in Relation to Production of Mushroom Compost
Applied and environmental microbiology, 1992Co-Authors: W. M. WiegantAbstract:Scytalidium thermophilum is an important thermophilic fungus in the production of Mushroom Compost. I investigated the characteristics of this organism and present a simple model with which fungal growth in Compost can be described. The model is used to predict better circumstances for rapid indoor production of Mushroom Compost. I conclude that inoculation of the starting material with prepared Compost either before or after the pasteurization phase has only a minor effect on the shortening of the Composting process. This is because the initial growth rate of the fungus is much higher than its growth rate later. A lower temperature (53.5°C instead of the usual 56 to 58°C) during the pasteurization phase may be most profitable for rapid Compost production; such a temperature may reduce the time that is needed for the last phase of the production process by at least 1 day.

removal of emerging contaminants using spent Mushroom Compost
Science of The Total Environment, 2018Co-Authors: Bea-ven Chang, Shaoning Fan, Yaochou Tsai, Yilin Chung, Chu-wen YangAbstract:Acetaminophen and sulfonamides are emerging contaminants. Conventional wastewater treatment systems fail to degrade these compounds properly. Mycoremediation, is a form of novel bioremediation that uses extracellular enzymes of white-rot fungi to degrade pollutants in the environment. In this study, spent Mushroom Compost (SMC), which contains fungal extracellular enzymes, was tested for acetaminophen and sulfonamides removal. Among the SMCs of nine Mushrooms tested in batch experiments, the SMC of Pleurotus eryngii exhibited the highest removal rate for acetaminophen and sulfonamides. Several fungal extracellular enzymes that might be involved in removal of acetaminophen and sulfonamides were identified by metaproteomic analysis. The bacterial classes, Betaproteobacteria and Alphaproteobacteria, were revealed by metagenomic analysis and may be assisting with acetaminophen and sulfonamide removal, respectively, in the SMC of Pleurotus eryngii. Bioreactor experiments were used to simulate the capability of Pleurotus eryngii SMC for the removal of acetaminophen and sulfonamides from wastewater. The results of this study provide a feasible solution for acetaminophen and sulfonamide removal from wastewater using the SMC of Pleurotus eryngii.

Biodegradation of tetrabromobisphenol-A in sludge with spent Mushroom Compost.
International Biodeterioration & Biodegradation, 2017Co-Authors: Chu-wen Yang, Wei-zhi Chen, Bea-ven ChangAbstract:Abstract The objective of this study was to evaluate the degradation of tetrabromobisphenol-A (TBBPA) in sludge with spent Mushroom Compost (SMC). The TBBPA degradation rates were enhanced by addition of either SMC, SMC extract or extract-containing microcapsule, with SMC showing the highest TBBPA degradation rate in sludge. Bioreactor experiments revealed that the TBBPA removal rates in sludge with SMC were higher than in sludge alone. The TBBPA removal rates were enhanced with SMC when TBBPA was added in two portions. The bacterial composition differed in sludge with and without SMC. Geobacter and Mycobacterium were the major bacteria responsible for TBBPA degradation in sludge. This research offers feasible methods for the removal of TBBPA from sludge.
