“…The treatments 2 -10% (m m -1 ) increased C/N ratio although, at the same time, overloaded the system by inhibiting the process of anaerobic methanogenic co-digestion, thereby decreasing biogas production (Panpong et al, 2014). Nghiem et al (2014) used in their study crude and purified glycerin, associated with sludge from a sewage treatment plant, using as inoculum the same digested sludge.…”

ABSTRACT. The addition of different concentrations of crude glycerin, associated with cattle manure, on the volumetric production of biogas is analyzed. Different concentrations of crude glycerin (2, 4 and 6% m m -1 ) were added as supplement in anaerobic co-digestion of dairy cattle waste, in laboratory batch biodigesters (3.5 L usable volume). The biodigesters were operated under mesophilic conditions (30ºC), with 30-day hydraulic retention time (HRT). Total solids (TS), volatile solids (VS) and chemical oxygen demand (COD) were analyzed to determine the efficiency of the process in the removal of organic matter and its effect on biogas production. The addition of 4% glycerin provided a larger production of biogas, approximately 9.307 mL. The efficiency in COD removal decreased in treatments with glycerin, with highest reduction (68%) in the control treatment. There was a 90 and 118% increase respectively for Gli4 and Gli6% treatments. VS reductions Gly 0, Gly 2, Gly 4 and Gly 6% treatments were 18.17, 61.60, 24.36 and 44.83%, for the respective treatments.Keywords: bio-digestion, cattle manure, biogas, crude glycerin, biodiesel.Avaliação da codigestão de glicerina associada a esterco bovino para produção de biogás no Estado do Paraná, Brasil RESUMO. O objetivo do trabalho foi avaliar o efeito da adição de diferentes concentrações de glicerina bruta associada com esterco bovino, sobre a produção volumétrica de biogás. A adição de diferentes concentrações de glicerina bruta (2, 4 e 6% m m -1 ) foi utilizada como suplemento na codigestão anaeróbia de dejetos bovinos de leite, em biodigestores laboratoriais de batelada (3,5 L de volume útil). Os biodigestores foram operados em condições mesofílicas (30ºC), com tempo de retenção hidráulica (TRH) de 30 dias. Foram analisados os sólidos totais (ST), sólidos voláteis (SV) e demanda química de oxigênio (DQO), a fim de determinar a eficiência do processo na remoção da matéria orgânica e seu efeito na produção de biogás. A adição de 4% de glicerina resultou na maior produção de biogás, cerca de 9,307 mL. A eficiência na remoção de DQO diminuiu nos tratamentos com adição de glicerina, sendo a maior redução no tratamento controle, de 68%. Nos demais tratamentos houve um aumento de 90 e 118% para os tratamentos Gli 4 e Gli 6% respectivamente. As reduções de SV para os tratamentos Gli 0, Gli 2, Gli 4 e Gli 6%, foram de 18,17, 61,60, 24,36 e de 44,83%, para os respectivos tratamentos.Palavras-chave: biodigestão, dejetos bovinos, biogás, glicerina bruta, biodiesel.

“…Feedstocks characterized by higher C/N ratios (>50), such as rice and wheat straws, corn stalks, seaweed, and algae, can be co-digested by the feedstocks of lower C/N ratios, for instance pig manure, poultry manure, and food and kitchen wastes, to achieve nutrient balance and to avoid the inhibition that leads to system instability and reduced biogas production as a result of an unsuited C/N ratio [26,[50][51][52]. Table 1 shows the possible feedstocks for co-digestion with regard to C/N ratio.…”

A Review on Anaerobic Co-Digestion with a Focus on the Microbial Populations and the Effect of Multi-Stage Digester Configuration

Recent studies have shown that anaerobic co-digestion (AnCoD) is superior to conventional anaerobic digestion (AD). The benefits of enhanced bioenergy production and solids reduction using co-substrates have attracted researchers to study the co-digestion technology and to better understand the effect of multi substrates on digester performance. This review will discuss the results of such studies with the main focus on: (1) generally the advantages of co-digestion over mono-digestion in terms of system stability, bioenergy, and solids reduction; (2) microbial consortia diversity and their synergistic impact on biogas improvement; (3) the effect of digester mode, i.e., multi-stage versus single stage digestion on AnCoD. It is essential to note that the studies reported improvement in the synergy and diverse microbial consortia when using co-digestion technologies, in addition to higher biomethane yield when using two-stage mode. A good example would be the co-digestion of biodiesel waste and glycerin with municipal waste sludge in a two-stage reactor resulting in 100% increase of biogas and 120% increase in the methane content of the produced biogas with microbial population dominated by Methanosaeta and Methanomicrobium.

“…It was 8 % more than waste water digestion alone. Continuous culture digestion in up-flow anaerobic sludge blanket (UASB) reactors resulted in 2.33 L CH4/L-reactor/day [78]. For value addition to the process of biodegradation of glycerol, the simultaneous production of acetate and methane were investigated.…”

The biodiesel industry has the potential to meet the fuel requirements in the future. A few inherent lacunae of this bioprocess are the effluent, which is 10 % of the actual product, and the fact that it is 85 % glycerol along with a few impurities. Biological treatments of wastes have been known as a dependable and economical direction of overseeing them and bring some value added products as well. A novel eco-biotechnological strategy employs metabolically diverse bacteria, which ensures higher reproducibility and economics. In this article, we have opined, which organisms and what bioproducts should be the focus, while exploiting glycerol as feed.
