“…In a field study, biogas yield of 0.41 and 0.47 L g -1 VS loaded is conducted by co-digesting CM, chicken manure without or with maize silage around 50 % VS reduction in mesophilic condition (Yangin-Gomec and Ozturk 2013). The higher than 60 % VS-COD reduction is often reported by co-digestion organic household waste and industrial organic waste (Bah et al 2014;Bertin et al 2013;Comino et al 2012;Comino et al 2009;Corro et al 2013;Solli et al 2014).…”

This literature review surveys the previous and current researches on the co-digestion of anaerobic processes and examines the synergies effect of co-digestion with cattle manure. Furthermore, this review also pays attention to different operational conditions like operating temperature, organic loading rate (OLR), hydraulic retention time (HRT), chemical oxygen demand (COD) and volatile solid (VS) removal efficiency and biogas or methane production. This review shows that anaerobic mono-digestion of cattle manure usually causing poor performance and stability. Anaerobic studies were generally performed under mesophilic conditions maintained between 35 and 37°C. Organic waste loading rate generally ranges from 1 to 6 g VS-COD L -1 day -1 stable condition in anaerobic digester. Generally, studies show that HRT for co-digestion of fruit-vegetables waste and industrial organic waste appears to exceed 20 days. However, the anaerobic co-digestion process is generally operated at HRT of between 10 and 20 days. VS and COD removal efficiency usually reaches up to 90 % due to codigestion with different type organic waste. Methane-biogas production is generally obtained between 0.1 and 0.65 L CH 4 -biogas g -1 VS.

“…Weed leaf foliage has been shown to be a viable feedstock for community-sized digesters, even when used exclusively as the sole feedstock input [51]. Furthermore, because the cheese production process generates large volumes of whey, which have low economic value but high organic matter content, this material could be readily used to supplement dung resources and improve biogas yields [52]. Dung collection also offers an opportunity to re-use the labour force currently linked to fuelwood harvesting, thus averting imminent redundancy should fuelwood harvesting be banned.…”

This study looks at how potential for resilient low-carbon solutions can be understood and enhanced in the diverse environmental, economic and socio-political contexts in which actual scenarios of energy needs and diverse development pathways take shape. It discusses socio-technical transition approaches to assist implementation of a biogas digester system. This will replace fuelwood use in the high forests of Central Nepal, where yak cheese production provides livelihood income but is under threat from the Langtang National Park, which is concerned to protect biodiversity. Alternatives for digester design are discussed, and the consultative issues for deliberative processes among stakeholders' varied agendas raised.

“…Co-digestion is a well-known concept for improving the biogas yield from different wastewater streams and biosolids due to positive synergisms in the microbiota, the supply of nutrients, the dilution of inhibitive compounds and the improved moisture content of the feed [2]. Several studies have investigated the co-digestion of different substrates, such as sewage sludge and grease trap sludge [3,4], cattle slurry and cheese whey [5], potato processing water and glycerol [6] and a number of different animal manures and energy crops, also mentioned in the white paper of renewable energy sources (RES) of the EU-Commission from 1997 [7].…”

This study presents the potential of combining anaerobic grey water sludge treatment with black water in an up-flow anaerobic sludge blanket (UASB) reactor to improve energy recovery within source-separated sanitation concepts. Black water and the mixture of black water and grey water sludge were compared in terms of biochemical methane potential (BMP), UASB reactor performance, chemical oxygen demand (COD) mass balance and methanization. Grey water sludge treatment with black water increased the energy recovery by 23% in the UASB reactor compared to black water treatment. The increase in the energy recovery can cover the increased heat demand of the UASB reactor and the electricity demand of the grey water bioflocculation system with a surplus of 0.7 kWh/cap/y electricity and 14 MJ/cap/y heat. However, grey water sludge introduced more heavy metals in the excess sludge of the UASB reactor and might therefore hinder its soil application.
