“…The thermochemical processes use heat and chemical reactions to transform biomass into energy or energy carriers while microorganisms and enzymes are used in the biological processes [9][10][11]. Several studies have reported the thermochemical and biological conversion of biomass to energy or energy carriers [12][13][14][15]. Fig.…”

Waste biomass has the potential to produce renewable fuels and fine chemicals. Biofuels derived from agricultural, forestry, and energy crop systems are promising resources to address climate change and minimize greenhouse gas emissions. The recent advances in various thermochemical technologies for the conversion of waste biomass to value-added biofuel products are discussed. A summarized outline of thermochemical technologies such as torrefaction, liquefaction, pyrolysis, and gasification is provided. An overview of different types and sources of biomass as well as their physicochemical properties is presented. The thermochemical conversion products and their environmental benefits are considered as well.

Hydrogen is the lightest element and is an excellent energy carrier due to high energy intensity. Hydrogen can be produced in a number of ways like physical, chemical and biological methods. Since the physical and chemical method of hydrogen production is energy intensive, research is currently concentrated on the biological methods. Among the biological method dark fermentation has gained greater attention because of its independence to light and the ability to use various substrates for fermentation. In this review, there is detailed information about biohydrogen production by dark fermentation using microorganisms including, the hydrogen producing anaerobic and facultative anaerobic bacteria, the enzymes involved, the factors affecting the process such as temperature, pH, substrates, hydraulic retention time and hydrogen partial pressure. Also a brief discussion about the metabolic engineering aspects in biohydrogen production and a note on microbial electrolysis cell has been discussed.

“…It is worth highlighting why waste diapers (WD) are attractive for biohydrogen production. Among the merits and benefits of this use of WD we can cite the following: (i) the WD have a high content of cellulose (40% db); earlier research has demonstrated that substrates and wastes rich in cellulose and hemicellulose or carbohydrates can produce an attractive amount of biological hydrogen (Rodríguez-Valderrama et al, 2020;Alvarez et al, 2020;Sarangi and Nanda, 2020;Solowski et al, 2020;Weide et al, 2019;Catalán and Sánchez, 2019;Yeshanew et al, 2018;Roy 2017;Robledo-Narváez et al, 2013). Thus, in principle, the potential of biohydrogen production of WD, could be very high.…”

“…If successful, DF of the OFWD would hold promise for integration to biorefineries from wastes that could co-ferment this waste with a variety of agricultural and agroindustrial wastes of similar characteristics (cellulosic and lignocellulosic wastes, i.e., food and textile wastes) (Rodríguez-Valderrama et al, 2020;Sarangi and Nanda, 2020;Solowski et al, 2020;Weide et al, 2019;Catalán and Sánchez, 2019;Yeshanew et al, 2018;Roy 2017;Robledo-Narváez et al, 2013). As it was hinted above, biological hydrogen production can be easily incorporated to several biorefinery platforms as a first stage of biofuel generation, followed by a network of processes devoted to obtaining value-added products and possibly more energy (Poggi-Varaldo et al, 2014).…”

Waste diapers (WD) handling and disposal in Mexico are typically based on their burial in dumping sites and landfills. Practically reclaiming and recycling of WD are non-existent. The clean diapers are composed of cellulose fibres (37–43% db), hemicellulose (5–9%), lignin (4–7%), protein (<1), plastics (polypropylene and polyethylene) (12–16%), absorbent sodium polyacrylate (14–18%), and elastic and adhesives tapes (9–12%). The latter can be valuable resources. WD composition is similar to clean diaper, although humidity is very high, and the ranges of faeces and urine are 1.5–2.5 and 6–9% dry weight, respectively. International literature searches indicate that there is some research on composting, fungal biodegradation, and methanogenic co-digestion of waste activated sludge with the organic fraction of waste diapers (OFWD.) However, research on dark fermentation of OFWD is limited. In this work, the generation of biohydrogen from dark fermentation of OFWD was optimised. We used the response surface methodology (RSM). Independent variables were the temperature of operation (37–55°C), ratio C/N of the feed (30, 40 gC/gN), and initial total solids of the feed (TSi) (15, 25%). The dependent (response) variables examined were Y’H2 (H2 produced per initial g of dry matter), contents of low molecular weight organic solvents and acids, lactic acid, the ratio A/B (acetic-to-butyric acid), and the quotient organic acids C2 to C4-to-solvents. The predicted maximum Y’H2 occurred at the combination of factors of 43 gC/gN, 12% and 31°C; its value was 2.79 mmolH2/gTS; its experimental validation gave 2.48 mmolH2/gTS, which shows a good agreement between values (11% lower than the predicted value). The maximum of Y’H2 with OFWD compared very favourably with bioH2 values obtained from a wide variety of wastes (organic municipal residues, agricultural wastes, etc.) using the same batch type fermentation with intermittent venting. Interestingly, the predicted temperature optimum fell in the lower side of the mesophilic range. Process heating savings would be in the order of 60.0 and 27.2% for thermophilic and mesophilic operation, respectively. In this way, it would be a contribution to the sustainability of the dark fermentation of OFWD. This result was somewhat counterintuitive and strongly indicates the usefulness of the response surface methodolog for analyzing the experimental results and uncovering favourable, although unexpected conditions.
