“…Researches have been done to try to enhance methane gas production during co-digestion of food waste by combining it with other organic matter (Fang et al 2011;Jiang et al 2013;Kabouris et al 2009;Kabouris 2008;L. Martín-Gonzáleza 2010;Long et al 2012).…”

Anaerobic Digestion Model Number1 (ADM1) was modified in order to predict accurately the impact of co-digesting bakery waste (BW) with municipal sludge (MS). BW is an industrial waste (300,000 gallons per day in USA) that contains a high concentration of organic matter (carbohydrates, low lipids and non-detected proteins). BW is an easily biodegradable substrate for creating a favorable microorganism growth environment, which enhances the biogas production needed for wastewater facilities. The modified ADM1 successfully predicted changes in pH, volatile fatty acids (VFA), propionic acid and methane gas production. The ADM1 outputs were compared to experimental batch reactor results of actual BW addition percentages in order to validate the model. Stability of the digestion process was achieved until the ratio range of 37-40% BW: 60-63% MS, and the digestion processes were inhibited at higher ratios of BW. This research provides an alternative to BW management through utilizing the BW to enhance methane production.

“…As evidenced by Girault et al [26] and Martin-Gonzalez et al [27], once an anaerobic consortium had overcome initial LCFA inhibition, the rate of biogas production increases to a similar rate as the controls. While the ATA was digesting cellulose, the recovery of the rate kinetics reproduced in the ATA indicated that bile produced reversible inhibition, while a dose of 6 g bile/L induced the first signs of decline in reaction kinetics.…”

A B S T R A C TBovine bile was assessed as a novel bio-surfactant pre-treatment to enhance anaerobic digestion of lipid-rich dissolved air flotation (DAF) sludge using biochemical methane potential (BMP) tests. Bile was dosed at arbitrary concentrations from 0.2-6 g/L. At 0.6 g bile/L, methane yield increased by 7.08%. Doses above 2 g bile/L produced negative impacts on SMP, kinetics and digestion profile. At 6 g/L bile produced a 6% decrease in specific methane production and up to 79% additional inhibitory duration, delayed time of peak methane production by up to 74%, and slowed total digestion time by up to 65%. Reaction kinetics declined linearly with respect to bile addition, reaching half the control value at 6 g/L bile concentration. Subsequent anaerobic toxicity assays between 1 and 6 g bile/L revealed that bile has an inhibitory effect under BMP testing at these higher doses. The economic viability of using bile as a bio-surfactant was assessed. In comparison to the current use of bile as a sale product to pharmaceutical companies, the addition of 0.2 g bile/L to existing slaughterhouse waste streams could increase the value of bile to 220% of its current sale value. The promising results of bile dosed at 0.6 g/L under BMP testing warrant further investigation into long-term impact of bile pre-treatments of high-fat slaughterhouse wastewater in semi-continuous digestion experiments.

“…Various studies have indicated that blends of agrarian, domestic and industrial wastes can be digested totally and efficiently with one another. in conclusion, the anaerobic system (AD) of individual substrates presents some problems related to substrate features as municipal sewage Sludge (MSS), described by low organic capacities, the municipal solid waste (MSW) could have contained inappropriate substances as well as high levels of heavy metals and salts , therefore The anaerobic co-digestion (multi substrates ) is the at same time AD of multi substrates is a convenient option to overcome the inhibitions of mono-digestion [26,27] …”

Abstract. Sustainable development is the projected demand of all nations at present. Only 20 percent of world's primary energy requirement is met by renewable sources like solar and wind energy, hydropower, bio mass, municipal and agri-wastes. Bio mass, can be utilized to produce biogas due to its high biodegradability, calorific value and nutritive value to microbes, which will reduce our dependency on fossil fuels so that These organic wastes require being managed in a sustainable way to avoid depletion of natural resources, minimize risk to hu man health, reduce environmental burdens and maintain an overall balance in the ecosystem. The annal of the Nat ional Office of Statistics (NOS) indicated that municipal solid waste overtook more and more million tons in 2016, almost 3.5 times the 1992 rates. About 40-70% of civilian solid waste CSW is composed of civilian bio mass waste (CBW), such as kitchen waste (KW), fru it/vegetable remains (FVR) and waste water sewage sludge (WWSS). There was a need to find several ways to deal with such wastes. One of these methods is the anaerobic digestion process, as a waste management system, has risen due to it has the usefulness of lowering volume and getting back energy. Several physical and chemical factors influence the creation of methane, and inhibition of bio-methane efficiency by certain materials (salts, oils, ammonia and toxic substrates ) may take p lace when inhibitors levels appear in high concentrations. In addition, high salt in the organic substrates can inhibit the activity of fermentation microbes by impacting the osmotic pressure of the cell wall of bacteria in the anaerobic system. The purpose of this study was to discuss the effect the types of substrates and salt content on biogas generation in anaerobic digestion.
