“…Our findings show that for a greater VS reduction using crude glycerin in co-digestion with swine manure, the best dose is about 5 g/100 g TS with a HRT of 20 days, as reported by Castrillón et al (2013), who obtained the greatest VS and COD reductions at 20 days by testing co-digestion of cattle waste with inclusion of 6 g/100 g TS in the solid influent.…”

-The objective of this research was to evaluate the performance of anaerobic co-digestion of swine excreta associated with increasing doses of crude glycerin and different hydraulic retention times (HRT). A completely randomized design was adopted in a 3 × 4 factorial arrangement composed of three HRT (10, 17, and 24 days) and four crude glycerin doses (0, 5, 10, and 15 g/100 g of total solids [TS]), with four replications per treatment. The assessed parameters were: biogas production potential, reductions of volatile solids (VS), chemical oxygen demand (COD), and most probable number of total and thermotolerant coliforms. The biogas production per added VS presented quadratic effect at 17 and 24 days of HRT, with ideal doses of 5.5 and 5.9 g of crude glycerin/100 g TS, respectively. There was no difference among glycerin doses at 10-day HRT for VS reductions; however, at HRT of 17 and 24 days, there were differences, with greater reduction of 61.1% for 5 g of crude glycerin/100 g TS at 24-day HRT. The COD reduction values showed an effect among retention times, in which the 24-day HRT provided the best results. Reductions in coliforms were greater than 99%, with no difference among treatments. Addition of 5 to 6 g of crude glycerin/100 g TS with a 24-day HRT is more effective in biogas production and reduction of VS, COD, and coliforms from co-digestion of swine excreta.

“…According to Castrillón et al (2013), crude glycerin is readily degradable, possibly due to high carbon, which is favorable to the anaerobic co-digestion. Therefore, the product might improve biogas yield up to 380% in swine waste substrates (Astals et al, 2012).…”

“…Some authors, however, have applied ultrasonication to other substrates, such as dairy cattle slurry (Luste and Luostarinen, 2011) or dairy cattle slurry plus industrial meat processing by-products (Luste et al, 2012). Our research group applied ultrasound to dairy cattle slurry supplemented with raw glycerin (Castrillón et al, 2011;Castrillón et al, 2013a), achieving very good results. When adding 6% glycerin to cattle slurry and applying an specific energy of around 1,100 kJ/kg TS, a methane yield of 590 L/kg VS and a volumetric biogas production of 56.5 minduced bed reactor at 55ºC and at OLR of 6.4 kg COD/m 3 .day (18 days HRT).…”

This paper present a study of the effect of applying ultrasound pre-treatment in the production of methane when co-digesting mixtures of cattle manure with food waste and sludge. A series of experiments were carried out under mesophilic and thermophilic conditions in continuously stirred-tank reactors containing 70% cattle manure, 20% food waste and 10% sewage sludge. Ultrasound pre-treatment allows operating at lower HRT, achieving higher volumetric methane yields: 0.85 L CH 4 /L.day at 36ºC and 0.82 CH 4 /L.day at 55ºC, when cattle manure and sewage sludge were sonicated. With respect to the non sonicated waste, these values represent increases of up to 31% and 67% for mesophilic and thermophilic digestion, respectively.

In this study, was studied the biogas generation from swine manure, using residual glycerine supplementation. The biogas production by digestion occurred in the anaerobic batch system under mesophilic conditions (35°C), with a hydraulic retention time of 48 days. The experiment was performed with 48 samples divided into four groups, from these, one was kept as a control (without glycerin) and the other three groups were respectively supplemented with residual glycerine in the percentage of 3%, 6% and 9% of the total volume of the samples. The volume of biogas was controlled by an automated system for reading in laboratory scale and the quality of the biogas (CH 4 ) measured from a specific sensor. The results showed that the residual glycerine has high potential for biogas production, with increases of 124.95%, 156.98% and 197.83% in the groups 3%, 6% and 9%, respectively, relative to the sample control. However, very high organic loads can compromise the process of digestion affecting the quality of the biogas generated in relation to methane.KEYWORDS: biogas, residual glycerin, swine manure, renewable energy. POTENCIAL DE PRODUÇÃO DE BIOGÁS ATRAVÉS DE DEJETOS SUÍNOS SUPLEMENTADOS COM GLICERINA RESIDUALRESUMO: Neste trabalho, estudou-se a geração de biogás a partir de dejetos suínos utilizando suplementação de glicerina residual. A produção de biogás ocorreu por meio de digestão anaeróbia no sistema em batelada sob condições mesofílicas (35°C), com tempo de retenção hidráulica de 48 dias. O experimento foi realizado com 48 amostras divididas em quatro grupos; destes, um se manteve como controle (sem adição de glicerina), e os outros três grupos foram suplementados, respectivamente, com glicerina residual nos percentuais de 3%, 6% e 9% do volume total das amostras. O volume de biogás gerado foi controlado por um sistema automatizado para leitura em escala laboratorial, e a qualidade do biogás (CH 4 ), medida a partir de um sensor específico. Os resultados obtidos demonstraram que a glicerina residual tem potencial para suplementar a produção de biogás, com incrementos de 124,95%, 156,98% e 197,83% nos grupos 3%, 6% e 9%, respectivamente, em relação à amostra-controle. Porém, cargas orgânicas muito elevadas podem comprometer o processo de biodigestão, afetando a qualidade do biogás gerado em relação ao metano.
