Biogas production is becoming increasingly important in the environmental area because, besides treating wastewaters, it also generates energy. Co-digestion has become more and more powerful since it is possible, with the use of abundant and cheap substrates, to dilute the inhibitory effects of various other substrates, making the process of anaerobic digestion more efficient and stable. Biogas...

Anaerobic digestion is applied widely to treat the source collected organic fraction of municipal solid wastes (SC-OFMSW). Lipid-rich wastes are a valuable substrate for anaerobic digestion due to their high theoretical methane potential. Nevertheless, although fat, oil and grease waste from sewage treatment plants (STP-FOGW) are commonly disposed of in landfill, European legislation is aimed a...

plug-flow digesters with periodic loading mechanism are more enthusiastic than fully mechanized digestion plants for the majority of small or medium scale farms according to the costs and operational complexities. a dual-compartment plug-flow reactor equipped with a passive heating system was designed and experimentally operated by purpose of demonstrating a simple and low cost technology for h...

Coming out from the growth kinetics, the Gompertz model has been developed and considered as the best one for simulating the biogas production from anaerobic digestion. However, the model has failed to describe the starting point of the process, and no-sense of lag phase constant has been pointed out. Thus, the goal of this study is to develop a new kinetic model of biogas production with meani...

In recent years many researchers show a high interest in co-digestion, simultaneous anaerobic decomposition of a homogenous mixture of at least two biodegradable waste. Anaerobic codigestion is reported to offer several benefits over digestion of separate materials, such as increased cost-efficiency, increased biodegradation of the treated materials, as well as increased biogas production. Most...

Anaerobic biological treatment can comprise a viable route of CH4 production through the energy recovery organic solid waste (OSW). This work therefore presented bibliometric analysis research trends on theme "Applicability via Digestion in Organic Solid Waste", considering experimental articles published from 2018 to 2022 Web Science database™; used VoSviewer software define trends, and found ...

Plant waste (PW) and excess sludge (ES) are two main organic matters of municipal solid waste. However, there few reports on their anaerobic co-digestion. In this work, the mixed proportion PW ES co-digestion was first optimized at mesophilic temperature, then enhanced with strong oxidant calcium peroxide (CP). The results showed that optimal mixing ratio 1/1 (in terms volatile solids), C/N dig...

The goal of this paper was to assess the possibilities for one-stage reactor anaerobic digestion processing fruit and vegetable biomass within a biorefinery concept optimum products. Co-digestion simplest strategy implement increase product yield among variables tested (pH, ultrasonification, co-digestion). Methane yields from co-digestion waste (FVW) pig manure (PM) ranged 318 434 NmL /g VS, w...

Over the last years anaerobic digestion has been successfully established as technology to treat organic wastes. The perspective of turning, through a low-cost process, organic wastes into biogas, a source of renewable energy and profit, has certainly increased the interest around this technology and has required several studies aimed to develop methods that could improve the performance as wel...
