“…), with a pH of 7 to 9.8 which is favorable for mushroom substrate preparation (Govasmark et al 2011;Hanc et al, 2011). Digestate from AD was successfully used in previous studies on Agaricus bisporus and Agaricus subrufescens by Stoknes et al (2013; and Jasińska et al (2016a and2016b).…”

Digestate is remaining material after anaerobic digestion (AD) of a biodegradable feedstock. The AD process produces two main products: digestate and biogas; digestate is considered as a waste; however, it found application in agriculture i.e. as a soil conditioner or cultivation substrate component. Digestate is rich in nitrogen and phosphorus and can be used as a substrate component for mycelial growth of mushrooms. Aim of the study was examination of agar media supplementation with digestate from AD of foodwaste material on mycelial growth of cultivated and medicinal mushrooms. Mycelial growth of four mushroom species was investigated: Coprinus comatus, Ganoderma lucidum, Agaricus subrufescens and Laetiporus sulphureus. First experiment investigated four mushroom species and 3 digestate-only based agar media with growing amount of digestate extract. Later fastest growing mushrooms from exp. 1, C. comatus and G. lucidum, was chosen, mycelial growth was performed on 2 digestate-only based agar media and 2 what/digestate extract based agar media. Wheat-based and manure-based agar media was used as control medium. Study confirmed positive effect of digestate from AD as an addition or main component of agar media culture for mushroom mycelium growth. The amount of digestate extract affected mycelial growth of investigated species. The best agar media was digestate-based only with 25 g of extract and wheat/digestate based (150/50 g extract). The fastest and the best growth were obtained for C. comatus. The residue from AD biogas production could have found additional application as media product for mushroom mycelia production and further as a component for mushroom cultivation substrate.

“…For example, Hanc et al (2011) studied the composition of household bio-waste and reported that the yearly percentage of grass amounted to 27.6±30.8% in single-family areas. The mean was 27.6% and its standard deviation 30.8%.…”

Statistical analysis of solid waste composition data: Arithmetic mean, standard deviation and correlation coefficients

Data for fractional solid waste composition provide relative magnitudes of individual waste fractions, the percentages of which always sum to 100, thereby connecting them intrinsically. Due to this sum constraint, waste composition data represent closed data, and their interpretation and analysis require statistical methods, other than classical statistics that are suitable only for non-constrained data such as absolute values. However, the closed characteristics of waste composition data are often ignored when analysed. The results of this study showed, for example, that unavoidable animal-derived food waste amounted to 2.21±3.12% with a confidence interval of (-4.03; 8.45), which highlights the problem of the biased negative proportions. A Pearson's correlation test, applied to waste fraction generation (kg mass), indicated a positive correlation between avoidable vegetable food waste and plastic packaging. However, correlation tests applied to waste fraction compositions (percentage values) showed a negative association in this regard, thus demonstrating that statistical analyses applied to compositional waste fraction data, without addressing the closed characteristics of these data, have the potential to generate spurious or misleading results. Therefore, ¨compositional data should be transformed adequately prior to any statistical analysis, such as computing mean, standard deviation and correlation coefficients.

“…Table 1. Municipal solid waste management practices in some countries Knowledge on the composition of waste is essential for implementing the most appropriate waste reduction policies and for choosing the adequate waste treatment and disposal processes because MSW composition varies substantially with location, season, socio-economic conditions, waste collection and disposal methods, sampling and sorting procedures and many other factors (Hanc et al 2011). However, the absence of reliable data on waste composition makes a regional and national evaluation of MSW management difficult.…”
