Biogas is among the biofuels that can be obtained from biomass resources, including biodegradable wastes like manure, sewage sludge, the organic fraction of municipal solid wastes, slaughterhouse waste, crop residues, and more recently lignocellulosic biomass and algae. Within the framework of the circular economy, biogas production from biodegradable waste is particularly interesting, as it helps to save resources while reducing environmental pollution. Besides, lignocellulosic biomass and algae do not compete for arable land with food crops (in contrast with energy crops). Hence, they constitute a novel source of biomass for bioenergy.Biogas plants may involve both high-tech and low-tech digesters, ranging from industrial-scale plants to small-scale farms and even households. They pose an alternative for decentralized bioenergy production in rural areas. Indeed, the biogas produced can be used in heaters, engines, combined heat and power units, and even cookstoves at the household level. Notwithstanding, digesters are considered to be a sustainable technology that can improve the living conditions of farmers by covering energy needs and boosting nutrient recycling. Thanks to their technical, socio-economic, and environmental benefits, rural biogas plants have been spreading around the world since the 1970s, with a large focus on farm-based systems and households. However, several challenges still need to be overcome in order to improve the technology and financial viability. 606 $aTechnology: general issues$2bicssc 606 $aEnvironmental science, engineering & technology$2bicssc 610 $aMixing 610 $aoptimised 610 $ahousehold digester 610 $aChinese dome digester (CDD) 610 $aself-agitation 610 $ablank 610 $amixing 610 $aChinese dome digester 610 $aimpeller mixed digester 610 $aunstirred digester 610 $ahydraulically mixed 610 $atotal solids (TS) concentration 610 $aplug-flow reactor 610 $aanaerobic digestion 610 $aanimal manures 610 $abiogas 610 $aunconfined gas injection mixing 610 $amixing recirculation 610 $abiomethane potential tests 610 $aItaly 610 $amanure 610 $aenergy crops 610 $aagriculture residues 610 $adigestate 610 $abiochemical methane potential 610 $amicro-aeration 610 $airon 610 $abioenergy 610 $aH2S scrubber 610 $amethane 610 $afermentation 610 $adairy 610 $apoultry 610 $aabsorbent 610 $aammonia 610 $ainhibition 610 $aacclimatization 610 $atrace elements 610 $aanaerobic treatment 610 $aenergy assessment 610 $arural sanitation 610 $asludge 610 $awastewater 610 $aagricultural runoff 610 $abiomethane 610 $abiorefinery 610 $amicroalgae 610 $aphotobioreactor 610 $apretreatment 610 $alow cost digester 610 $apsychrophilic anaerobic digestion 610 $athermal behavior 610 $aanaerobic co-digestion 610 $aslaughterhouse wastewater 610 $asynergistic effects 610 $akinetic modeling 610 $abiodegradability 615 7$aTechnology: general issues 615 7$aEnvironmental science, engineering & technology 700 $aFerrer$b Ivet$4edt$01322269 702 $aLansing$b Stephanie$4edt 702 $aMartí-Herrero$b Jaime$4edt 702 $aFerrer$b Ivet$4oth 702 $aLansing$b Stephanie$4oth 702 $aMartí-Herrero$b Jaime$4oth 906 $aBOOK 912 $a9910557619703321 996 $aBiogas for Rural Areas$93035471 997 $aUNINA
