“…With the exception of biogas production via the anaerobic co-digestion route [21][22][23]77], the amount of literature available with respect to the use of mixed lignocellulosic biomass sources for bioenergy applications is limited compared to those of single feedstocks. This can be attributed to the limitations and challenges associated with this approach [72].…”

“…MLB have been investigated for the production of biohydrogen [19,20], biogas/methane [21][22][23], polyhydroxyalkanoates [24,25], microbial enzymes [25][26][27] and some power, heat, and cooling applications [13,[28][29][30][31]. Biomass has also been used in combination with coal for power generation solely [32,33], and for combined heat and power (CHP) systems [34].…”

Mixed Feedstock Approach to Lignocellulosic Ethanol Production—Prospects and Limitations

Lignocellulosic ethanol is a promising alternative to fossil-derived fuels because lignocellulosic biomass is abundant, cheap and its use is environmentally friendly. However, the high costs of feedstock supply and the expensive processing requirements of lignocellulosic biomass hinder the development of the lignocellulosic biorefinery. Lignocellulosic ethanol production so far, has been based mainly on single feedstocks while the use of mixed feedstocks has been poorly explored. Previous studies from alternative applications of mixed lignocellulosic biomass (MLB) have shown that their use can bring about significant cost savings when compared to single feedstocks. Although laboratoryscale evaluations have demonstrated that mixed feedstocks give comparable or even higher ethanol yields compared to single feedstocks, more empirical studies are needed to establish the possibility of achieving significant cost savings in terms of pre-biorefinery logistics. In this review, some potential benefits of the use of MLB for ethanol production are highlighted. Some anticipated limitations of this approach have been identified and ways to surmount them have been suggested. The outlook for ethanol production from MLB is promising provided that revolutionary measures are taken to ensure the sustainability of the industry.

Abstract. Intense development of research equipment leads directly to increasing cognitive abilities. However, along with the raising amount of data generated, the development of the techniques allowing the analysis is also essential. Currently, one of the most dynamically developing branch of computer science and mathematics are the Artificial Neural Networks (ANN). Their main advantage is very high ability to solve the regression and approximation issues. This paper presents the possibility of application of artificial intelligence methods to optimize the selection of cosubstrates intended for methane fermentation of chicken manure. 4-layer MLP network has proven to be the optimal structure modeling the obtained empirical data.

“…Other studies have evaluated continuous against semi-continuous mesophilic anaerobic digestion under varying organic loading rates. These studies concluded that biochemical methane production was slightly better in the semi-continuous systems, and also increased in both types as the organic loading rate increased up to 6 kg/m 3 /-day, after which methanogenesis inhibition was likely due to volatile fatty acid accumulation that occurred (Escudero et al, 2014;Li et al, 2014b). Wang et al (2014) presented a feeding strategy that alternated the substrate composition (i.e.…”

The goal of this research was to understand the effect of solids retention time (SRT) and feeding frequency on the performance of anaerobic digesters used to recover bioenergy from swine waste. Semi-continuous mesophilic anaerobic digesters were operated at varying SRTs and feeding frequencies. Performance metrics included biogas and methane production rates, biomass robustness and functionality and removals of volatile solids, soluble chemical oxygen demand, the fecal-indicator bacteria Escherichia coli, and the human pathogen Salmonella. Biochemical methane formation potential and specific methanogenic activity assays were used to demonstrate biomass robustness and functionality. Results indicated that anaerobic digesters fed weekly had higher average methane yields (0.20 vs. 0.18m(3)CH4/kg-VSadded), specific methanogenic activities (40 vs. 35ml/day), and fecal indicator bacteria destruction (99.9% vs. 99.4%) than those fed every-other day. Salmonella, soluble COD, and VS destruction did not change with varied feeding frequency; however, higher removals were observed with longer SRT.
