“…FW is a feedstock mostly treated in AD, and it has a lipid‐rich resource with a lipid concentration of 5.0 g/L . During lipid degradation process, long‐chain fatty acids (LCFA) are mainly composed of oleic acid (C18:1), linoleic acid (C18:2), and palmitoleic acid (C16:0) as the main intermediate by‐products of lipid degradation process . LCFA can also be further converted to hydrogen and acetate by AD acetogenic bacteria through a β‐oxidation process, and finally to methane via methanogenic archaea .…”

VFA accumulation can exist from a high organic load, which can, therefore, influence pH in an AD; hence, their concentrations could be used as an indicator of reactor performance.…”

Food waste (FW) is a severe environmental problem all over the world, and the recalcitrant organic residues (ROR) from FW treatment plant operations are also a critical environmental issue due to unsustainable treatment and disposal techniques.Requirements for FW and ROR complete exploitation with the establishment of recycling-renewable technologies are very crucial. This paper review AD and pyrolysis as two promising technologies to degrade FW and its residues, creating numerous renewable bioenergy yields with value-added. Existing oil/tar application methods in the AD suffered from various problems such as microorganism toxicity and limited productivity. Future upgrading techniques considering the second-stage pyrolysis process to decompose oil/tars for syngas with high hydrogen content and enhanced bio-methanation in the AD were addressed. Simultaneous pyrolysis by-product recycle in the AD during the valorization of FW are aimed to have the features of sustainability toward increased bioenergy production, reactor efficiency, and agricultural application.

“…Hence, recent research focus is on the co-digestion of OFMSW with other substrates in biodigesters e.g. sewage sludge (Sosnowski et al, 2003;Silvestre et al, 2015;Abudi et al (2016); Grosser et al, 2017); manure (Hartmann and Ahring, 2005;Capela et al, 2008;Macias-Corral et al, 2008;Matheri et al (2017)), fruit and vegetable waste (Pavi et al (2017) and agricultural residue (Negi et al, 2018). The co-digestion of OFMSW with a co-substrate may stabilize AD process conditions such as C/N ratio, macro and micronutrients, pH, total solids, inhibitors/toxic compounds and so increase biogas production (Matheri et al, 2017;Guven et al, 2017;Pavi et al, 2017;Matheri et al, 2017;Negi et al, 2018).…”

Anaerobic Conversion of Biodegradable Municipal Solid Waste to Biogas: A Review

Huge quantity of Municipal Solid Waste (MSW) is generated daily. This waste comprises a biodegradable portion which can be converted into biogas (bioenergy) by anaerobic digestion (AD). This study reviews MSW and its management, AD feedstock and their characteristics, factors affecting biogas production in a biodigester and anaerobic co-digestion of Organic Fraction of MSW (OFMSW) with other substrates. Municipal solid waste is managed through waste diversion (reduction, reuse, recycling and recovery) and waste disposal (controlled incineration, landfilling and controlled dumping). AD feedstock includes agricultural waste/residues, animal wastes, energy crops, food waste, forestry crops and residues, organic industrial waste and wastewater, weeds, aquatic algae, sewage and OFMSW. The essential factors that influence the production of biogas are temperature, pH, mixing rate, carbon/nitrogen ratio, organic loading rate, micro and macro-nutrient availability, retention time, nature of the feedstock and digester type. Anaerobic co-digestion of OFMSW with other substrates results in improved AD process stability, enhanced biogas productivity, maximization of the capacity of available feedstock for anaerobic digestion. It is also a cost-effective and improved technique to optimize anaerobic digestion process via the increase in nutrients and bacterial variety in substrates. The generation rate and composition of MSW, as well as the characteristics of OFMSW feedstock for anaerobic digestion, are required for the design of a full-scale biodigester for municipal use. The information provided in this review is invaluable to researchers, governments, industries and other stakeholders interested in anaerobic conversion of biodegradable solids to bioenergy.

“…Moreover, there exist few publications in which a three-substrate co-digestion is studied, especially applying AB as the third co-substrate. For instance, Grosser et al [16] obtained an improved methane yield up to 82% for co-digestion of sewage sludge, organic fraction of municipal solid waste and grease trap sludge. In turn, Ahmed et al [17] recorded a 179% increase in biogas production for a mixture containing sewage sludge, microalgae and sawdust, while Solé-Bundó et al [18] observed a significant increase in methane yield during the co-digestion process.…”

Sewage sludge (SS) generation and its management still pose a problem in many countries. Anaerobic co-digestion (AcD) of SS with grease trap sludge (GTS) and organic fraction of municipal sewage waste (OFMSW), which are two easily biodegradable substrates, may improve biogas production and AcD kinetics. Algae biomass (AB) of the species Undaria pinnatifida can be the third co-digestion component that may also affect the AcD performance. The aim of the study was therefore to evaluate the performance of mesophilic and thermophilic SS batch AcD with OFMSW, GTS as well as AB through biochemical methane potential (BMP) assay in relation to cumulative specific biogas (YB) and methane yields (Ym). Three kinetic models were applied within the scope of the kinetic study. Results of the study showed that the mixture containing SS, GTS and AB brought the most noticeable improvements in Ym compared to other studied mixtures and in respect to standalone SS digestion, the improvement amounted to 88.37% at mesophilic temperature (260.83 ± 15.02 N mL CH4/g-VSadd and for standalone SS 138.47 ± 4.70 N mL CH4/g-VSadd) and 71.09%, respectively, at the thermophilic one (275.66 ± 4.11 N mL-CH4/g-VSadd and for SS standalone 161.13 ± 13.11 N mL-CH4/g-VSadd).
