Use of Spent Mushroom Substrate in New Mushroom Crops to Promote the Transition towards A Circular Economy

et al. 2020

The use of spent mushroom substrate (SMS) in new cultivation cycles has already been reported due to its economic and environmental viability. When considering the application of the circular economy concept in the production of edible mushrooms, the re-use of the SMS within the same process is highly attractive, because it allows a better use of the biomass and the energy involved in the process and, therefore, tends to improve energy efficiency and resource conservation. However, this alternative generates important challenges, which derive from maintaining the quality standards of the mushrooms produced and, at the same time, not incurring excessive costs that are detrimental to the process itself. In our opinion, the main difficulty of the process in achieving success is regarding the biological and agronomic parameters that involve the production of the mushroom. It is useless to apply SMS in new cycles if the mushroom harvest is impaired and farms become non-viable. However, numerous examples are reported here where SMS was recycled into new substrates for either the same or different mushroom species without negatively affecting yield compared with using substrates prepared from 100% fresh raw materials. Thus, we suggest that each farm has its own specific technological study, since a small variation in the raw material of the compost, and mushroom cultivation practices and casing layer used, can influence the entire viability of the mushroom circular economy.

“…Wang et al [33] established the applicability of post-harvest asparagus residues in the cultivation of Agaricus blazei Murrill. In turn, Gern et al [34] successfully used the used substrate remaining after the cultivation of Pleurotus spp., with the addition of rice bran. The substrate is fermented during composting, with microbiological changes and changes in the C:N ratio occurring during the composting process [35].…”

The vitamin content of cultivated mushrooms differs from one species to another, depending on their stage of development, the nutrient substrate used to produce them, and the microclimate in the culture space. Agaricus blazei Murrill is one of the most popular cultivated medicinal mushrooms, with scientifically proven therapeutic properties. Considering that the Agaricus spp. mushrooms culture substrate can be produced using various raw materials, in this paper we have studied the influence of the culture substrate using four types of substrate with different protein additions on the vitamin content of mushrooms. The food qualities of the Agaricus blazei Murrill mushrooms, evaluated by the chemical composition, generally revealed the product obtained on the classic compost, improved with the addition of proteinaceous of corn flour. Mushrooms harvested on this substrate have the highest levels of B1 (1151 μg 100g−1 dm), B9 (671 μg 100g−1 dm), B12 (906 μg 100g−1 dm), PP (55.33 μg 100g−1 dm), and C vitamins (21.67 μg 100g−1 dm). The content of ergosterol, as a precursor of D2 vitamin, has higher values in the product obtained on the classic compost, with the addition of wheat bran (90.17 mg 100g−1 dm) and the addition of corn flour (94 mg 100g−1 dm).

“…SMS is often considered as a farm/agro-waste [42,43]. To reduce the problems associated with accumulating amounts of SMS, the potential utilisation of this material in subsequent mushroom production is the best and most economically viable method [21,44], which can result in sustainable use of waste resources, generating a circular economy [44][45][46][47].…”

Combined Dairy Manure-Food Waste Digestate as a Medium for Pleurotus djamor—Mineral Composition in Substrate and Bioaccumulation of Elements in Fruiting Bodies

et al. 2022

The present investigation aimed to study the utilisation of combined dairy manure-food waste digestate as a substrate (experimental mushroom substrate—EMS) for Pleurotus djamor (strain 2708, Mycelia) cultivation. Considering the lack of scientific information about the influence of elements concentration in growing substrates on the bioaccumulation of elements in cultivated mushrooms and their residual concentrations in substrates left after cultivation (spent mushroom substrate—SMS), a multi-elemental analysis of 38 elements was carried out. In the study, inductively coupled plasma optical emission spectrometry (ICP OES) was used for elemental analysis. The P. djamor cultivated on EMS resulted in a yield of 196.50 g/bag, achieving a biological efficiency (BE) of 39.90%. High variability in the elemental concentrations among substrates both before and after mushroom cultivation was evident. The studied elements accumulation in P. djamor was in an increasing trend in three subsequent flushes and was also reflected in the bioconcentration factors (BCFs). The highest BCF (2.35) was determined for Fe. Interestingly, the BCF values for all studied trace elements with detrimental health effects were lower than 1.00. The estimated daily intake (EDI) reflected that the P. djamor fruiting bodies grown on EMS can serve as an excellent dietary source of essential major and trace elements: Ca, Mg, Na, Mn, Mo, Ni, Se and Zn. On the other hand, EDI values for K, Cu, Fe, Ag, Ba, Cd, Al, Sb and Sr were greater than the referred guideline values corresponding to higher intake. Overall, the study presented an insight into elemental accumulations and demonstrated the potential utilisation of combined dairy manure-food waste digestate.
