“…Considering a commercial mushroom cultivation, i.e., Agaricus bisporus that can attain a yield of 40% of substrate weight (ratio of fresh mushroom weight harvested divided by the fresh weight of the substrate, multiplied by 100), every 1 kg of fresh mushroom generates 2.5 kg of fresh SMS. Emphasizing that in the cultivation of A. bisporus a casing layer is positioned over the compost, every 1 kg of fresh mushrooms generates 3.24 kg of fresh SMS, including the spent peat + limestone casing [17]. Mushrooms that have a lower conversion efficiency than A. bisporus can result in 5 kg of fresh SMS for every 1 kg of fresh mushrooms produced [18].…”

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.

“…SMS is often discarded as waste after mushroom harvest in many countries (Chiu et al, 1998;Hanafi et al, 2018). For every 1 kg of mushrooms produced about 5 kg of SMS remains (Zisopoulos et al, 2016). Therefore, SMS management has become a growing challenge for the mushroom production industry.…”

Potential utilization of spent Agaricus bisporus mushroom substrate for seedling production and organic fertilizer in tomato cultivation

et al. 2019

The production of Agaricus bisporus results in significant residual material after cultivation. Due to its physical properties and nutrient content Spent Mushroom Substrate (SMS) has great potential for use in agriculture. Our study evaluated the feasibility of using SMS as an alternative substrate for the production of Paronset® hybrid tomato seedlings and as an organic fertilizer in its production. To conduct the fruit production experiment, the plots consisted of three types of fertilizers (SMS of A. bisporus, NPK and bovine manure) with four replications. The seedlings produced in the SMS presented higher rates of germination time and speeds, and stood out from the other substrates in the evaluation of seedling quality. In the tomato fruit production phase, the average production of the plants originating from the SMS was 20% higher than the seedlings from the commercial substrate. The plants cultivated with the SMS presented higher production than the plants cultivated with bovine manure incorporated the soil. According to our results, The SMS was as good as the commercial substrates tested. Therefore, the SMS can be recommended for the growth and nutrition of seedling production and denotes potential viability for use in the tomato production cycle in its different phases.

“…The approximation bias is likely to be small due to stable input-output relations. In general, when choosing underlying assumptions and data, it should be kept in mind that moderate variations can significantly change final estimates quantitatively and qualitatively (Zisopoulos et al 2016).…”

The Nationally Determined Contributions pledged by numerous countries under the Paris Climate Agreement refer to efficiency gains as a key instrument for achieving carbon emission reductions. Indicators for estimating emission savings from resource efficiency projects can play a key role in identifying and prioritising projects. Building on existing emission factor-based approaches, this paper introduces a methodology which allows consistent ex-ante estimation of lifetime carbon savings from corporate resource efficiency investments. This methodology accounts for the intertemporal dimension of resource savings and project lifetimes and allows consistent aggregation across resource and project types. Moreover, it shows how social benefit (or cost) can be monetised. The methodology is tested using a resource efficiency investment project under the UN Clean Development Mechanism. We demonstrate that this indicator can be a robust, coherent and practical tool for firms, governments and investors to estimate carbon emission reductions from resource efficiency investments.
