“…Treatment C had the lowest efficiency in COD removal values (Table 3) up to the end of the process, which is different from the report of Pazuch et al (2017), with a value of 68%, but in a anaerobic-digestion process where cattle manure and crude glycerin were used. However, these results are similar to those shown by Nuchdang and Phalakornkule (2012) with values >80% that used anaerobic digestion and co-digestion of glycerol and pig manure.…”

Anaerobic co-digestion improves the pig faeces digestion process. This work presents anaerobic digestion of pig faeces (C) as compared to 2 co-substrates: Sludge (L) from waste waters and bovine ruminal gastric content (R). Pig faeces used were generated in a local farm at the Juarez Autonomous University of Tabasco (UJAT), with a total population of 148 animals. Analytical determinations were made on the substrate and co-substrates. Each treatment was performed in triplicate (9 experimental units), for 18 weeks. C+R co-digestion had the highest removal of chemical oxygen demand (COD) with 90%. Biogas production (0.012 L day Results obtained showed that co-digestion of C+L was better with regards to the quality of biogas from low hydrogen sulfide (H 2 S) concentrations (70.33±6.36 ppm). The use of anaerobic co-digestion systems represents an alternative treatment for faeces generated in pig farms and other kinds of wastes to reduce the potential source of infection produced by these types of waste.

“…[45] Sandriaty et al [46] also reported the emergence of sCOD after the biochemical methane potential test conducted in their experiment. Pazuch et al [47] highlighted the possibility of COD increase during digestion due to the organic load of the substrates. Similarly, Barua and Kalamdhad [48] reported the fluctuations of sCOD in the digestion of untreated WH for 50 days, which led to the highest biogas yield achieved on day 32 of the digestion, during which the sCOD was the highest.…”

Leftover harvested water hyacinth biomass and duck manure can create waste management issues. As they are readily abundant and available, potential co-digestion of both waste sources for biogas production is explored as a waste-to-energy approach for a rural fishermen community. Seven 19-L do-it-yourself bioreactors are constructed with four different feedstock mixing ratios. The mixing ratios of water hyacinth to duck manure are varied at 70:30, 50:50, and 30:70, and are conducted in duplicate. One reactor utilizing 100% water hyacinth as feedstock acts as the control. Biogas production is measured daily for 50 days through the water displacement method. Variations in pH and chemical oxygen demand levels are monitored weekly. The results show that the highest biogas production is from the mixture of water hyacinth to duck manure at a 70:30 ratio (p < 0.05), with a volume of cumulative gas produced at 4.27 L that can be well simulated through the logistic function kinetic model (R 2 = 0.965). The biogas produced consists of methane, carbon monoxide, and hydrogen sulfide. The findings prove the potential of water hyacinth and duck manure as feedstocks for biogas production as one of the waste management solutions that can be practiced by the community.

“…Therefore, it has been stated that the use of renewable fuels, such as biofuels, is one of the strategic alternatives to modify the energy matrix of countries, and the use of biogas for electricity generation is likely to be increasingly fostered in Brazil (Pazuch, 2017). Given this, it can be said that the use of biogas is promising.…”

Faced with the increasing demand for renewable energy, researchers have developed several ways to generate them, such as biogas. Thus, the present study aims to demonstrate the economic viability of electricity generation from biodigesters in a pig farm to contribute to sustainable development by reducing pollution in the environment. Studies focused on biomass derived from pig waste are still scarce. Moreover, one of the motivations of the present study is the fact that Brazil is a major producer and exporter of pig meat, with most of the production taking place in the south and southeast regions. The methodology used is defined as exploratory, descriptive, explanatory, and applied. The scientific procedures were documentary and bibliographic research, case study, and cost analysis. An economic management model was developed using financial management instruments such as cash flow, internal rate of return, and simple and discounted payback, confirming the economic viability of the investment made for generating energy from animal biomass produced in a pig farm located in the interior of Rio Grande do Sul.
