“…Results revealed that a mixture of lignocellulosic biomass and food waste can increase the yield of H2, with a reduction of phenolic compounds and indirectly decreasing climate change. Ortigueira et al (2020) evaluated a food waste biorefinery using an acidogenic fermentation approach mixed with carbon dioxide sequestration to convert food waste into Hydrogen (H2). In a scenario where the authors considered the reuse of fermentation sludge as a source of nitrogen within the acidogenic fermentation, global warming potential emissions were reduced by over 60 %, so upscaling this approach has the potential to reduce emissions from food waste.…”

“…In this case, a 1.65 L bench-scale double jacketed glass bioreactor with a working volume of 0.5 L, equipped with a pH sensor (405-DPAS-SC-K8S/250, Mettler Toledo, Columbia, MD, USA) and controller (MOD 7F, SGI, USA) was used. The operational settings were according to Ortigueira et al [54,55].…”

A methodology was developed to assess the allocation of different types of endogenous waste biomass to eight technologies for producing electricity, heat, biogas and advanced biofuels. It was based on the identification of key physicochemical parameters for each conversion process and the definition of limit values for each parameter, applied to two different matrices of waste biomass. This enabled the creation of one Admissibility Grid with target values per type of waste biomass and conversion technology, applicable to a decision process in the routing to energy production. The construction of the grid was based on the evaluation of 24 types of waste biomass, corresponding to 48 sets of samples tested, for which a detailed physicochemical characterization and an admissibility assessment were made. The samples were collected from Municipal Solid Waste treatment facilities, sewage sludges, agro-industrial companies, poultry farms, and pulp and paper industries. The conversion technologies and energy products considered were (trans)esterification to fatty acid methyl esters, anaerobic digestion to methane, fermentation to bioethanol, dark fermentation to biohydrogen, combustion to electricity and heat, gasification to syngas, and pyrolysis and hydrothermal liquefaction to bio-oils. The validation of the Admissibility Grid was based on the determination of conversion rates and product yields over 23 case studies that were selected according to the best combinations of waste biomass type versus technological solution and energy product.

“…Dark fermentation consists in the biological conversion of carbohydrate-rich biomass by strict or facultative anaerobic microorganisms, with the production of H 2 , CO 2 and organic acids. Given the versatility of the biocatalysts, there is a wide variety of waste biomass types that can be used as a substrate for dark fermentation: the by-products of biodiesel production containing glycerol, hydrolysates obtained by enzymatic treatment of waste from the pulp and paper industry; food waste, agricultural and agro-industrial byproducts or residues, such as brewery spent grain, corn cob and carob pulp, and spent microalgal biomass (Ortigueira et al, 2018(Ortigueira et al, , 2020.…”
