“…Over the last years, several authors investigated the effect on the performance of the AD process by simultaneously treating cattle manure as well as wastes containing high levels of organic matter or energy crops (Alvarez and Liden 2008;Comino et al 2009;Lehtomaki et al 2007;Nasir et al 2012;Yangin-Gomec and Ozturk 2013). This co-digestion method, if co-substrate is used at the appropriate rate, can give interesting results because the synergistic impact indicated by different organic substrates when processed simultaneously (Angelidaki and Ellegaard 2003;Chen et al 2010;Dias et al 2014;El-Mashad et al 2004;Hills and Roberts 1981;Lehtomaki et al 2007;Li et al 2009Li et al , 2011Macias-Corral et al 2008;Mata-Alvarez et al 2000;Rao and Baral 2011;Umetsu et al 2006). For optimal carbon-to-nitrogen ratio and pH diverse substrates are mixed for best biogas production (Khan and Martin 2016).…”

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.

“…Fruits and vegetables have low nitrogen and phosphorous content, thus they suffer from a nutrient deficiency and are difficult to treat alone. Moreover, co-digestion of dairy manure with fibrous material presents a rare opportunity of adding value to the digestate, which is applied as organic fertilizer [40,44].…”

Dairy manure is an abundant waste in dairy farming and poses handling, storage and disposal challenges. With poor management, dairy manure produces odour, ammonia and releases greenhouse gases that contribute to global warming. Anaerobic digestion (AD) is a means to produce renewable energy and to reduce environmental impacts resulting from improper management of dairy manure. Dairy manure AD suffers from low biogas production per unit mass, hence it is costly per unit volume. To improve biogas production per unit volume, anaerobic co-digestion of dairy manure is one of the methods used to enhance biogas production. This article reviews various approaches and challenges of co-digestion to enhance biogas production and methane yield that have been used in the last decade. Substrate selection and prediction of biogas production based on chemical oxygen demand are the main areas of focus. Process inhibition by co-substrates is also examined.

“…Although biodegradable organic matter could be used as sole feedstock in anaerobic digestion, the digestion process tends to fail without the addition of external nutrients and buffering agents [1]. Co-digestion with animal manure or sewage sludge as base feedstock is an effective way to improve buffer capacity and achieve stable performance [2][3][4][5]. On the other hand, the addition of readily biodegradable organic matter into animal manure digester could significantly increase biogas production due to the changes of feedstock characteristics.…”

The study was conducted to investigate the production of biogas from kitchen waste (KW) with co-digestion of cow manure (CM) by using anaerobic digestion process. The experimental protocol was defined to examine the effect of organic loading rate (OLR), temperature, and NaOH-treatment on the efficiency of the production of biogas. A portable biogas reactor was fabricated for efficient biogas production which included an agitation and a heating system. The KW and CM were co-digested at ratios of 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 7:1 and 8:1 respectively at loading rates of 50, 100,150, 200, 250, 300, 350, and 400 g/L. The highest degradation rate of 7.96 ml/g was obtained from the loading rate of 200 g/L. Furthermore, KW was co-digested at different temperatures 25, 35, 40, 45, and 50 0 C, maintaining the same loading rate of 200 g/L and the highest degradation rate of 7.98 ml/g was inspected at temperature 35 0 C. The alkali (NaOH) was used to treat KW to improve biogas production and four NaOH doses 0.5%, 1.0%, 1.5%, and 2.0% on wet matter basis of KW were applied. The highest degradation rate 13.21ml/g was obtained from 1.5% NaOH which was almost double compared to untreated KW. In addition, 39.74 % more biogas could be produced from 1.5% NaOHtreated KW than untreated KW. The results were further verified by scaling up to a semi-continuously-operating pilotplant reactor co-digesting KW with CM as bacterial seed and confirmed that no negative impact was imposed at optimized conditions.
