Background: Korshinsk peashrub branches are agroforestry byproducts that accumulate in millions of tons per year and need to be rationally and efficiently utilized. To maximate the utilization value of Korshinsk peashrub branches, an integrated process was proposed and conducted by using Korshinsk peashrub branches as the main substrate ingredient for Pleurotus tuoliensis cultivation and performing anaerobic digestion of spent mushroom substrate for methane production in this study.
Results: It was found that the substrate including 45% Korshinsk peashrub branches obtained higher mushroom yields than that using a commercial substrate, and anaerobic digestion of spent mushroom substrate from P. tuoliensis cultivation achieved a high cumulative methane yield. Preliminary calculation suggested that, for every kg of Korshinsk peashrub branches consumption, 1.12 kg mushroom product and 8578 L methane were produced, obtaining actual economic value of RMB 27.5 Yuan. In addition, this integrated stragety have positive ecological and social benefits.
Conclusion: The value of Korshinsk peashrub branches can be maximized by P. tuoliensis cultivation and anaerobic digestion of spent mushroom substrate, which not only promote the biological conversion of Korshinsk peashrub branches to circle economy, but also be beneficial for the sustainable development of environment, energy conservation and edible fungi industry.
