“…The results showed that the mixture mentioned boosted CH 4 generation (568 Nl CH 4. g VS ‐1 ) compared to isolated substrates. The main gains achieved with pentose liquor and vinasse 1G were 12.7% and 15.4% higher than individually, respectively 18 …”

“…The main gains achieved with pentose liquor and vinasse 1G were 12.7% and 15.4% higher than individually, respectively. 18 Other survey showed that combining swine manure and sugarcane vinasse in different proportions of total solids (TS) resulted in higher yield compared to vinasse-straw. The hydrogenotrophic methanogenesis pathway is not carried out appropriately in some unknown proportions of swine manure, most likely due to the high nitrogen content in the form of ammonia, which can inhibit CH 4 conversion.…”

Brazil's agriculture and livestock annually generates enormous amounts of biomass, which varies in its biochemical composition. Many studies have pointed out the benefits of using this biomass as a substrate for biogas production through anaerobic digestion (AD), mostly via the co‐digestion (co‐AD) pathway. The agriculture and livestock of southeastern Brazil – sugarcane, orange, corn, soybean, coffee, cattle, swine, and poultry – have together demonstrated their potential for producing biomass that can be used for maximizing methane production. Filter cake, vinasse, straws, bagasse, mucilage, pulp, washing water, thin stillage, and manures also have specific organic matter and nutrient content that can be evaluated from an economic perspective as co‐products of biorefineries. Some are costless but others have acquisition costs in the agricultural market. Comparing the recent biochemical compositions cited in scientific literature (technical parameter) and to know the costs (valuation parameter) is crucial for farmers and investors make decisions in large‐scale. This study conducted a bibliographical survey of biomass generated in Brazilian agroindustry as a co‐substrate for energy production. The analysis summarized two tables: 1‐ a compilation of biochemical composition of the main co‐substrates, and 2‐ the acquisition or opportunity costs, discussing innovative aspects in the context of biogas production. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…To quote, the application of vinasse for irrigation is only considered because it contains inorganic compounds, particularly potassium (K), an important nutrient for soil fertilization (Lucas Tadeu Fuess, 2017). The high organic matter content indicates its potential AD substrate (Lima, 2020;Moraes et al, 2014). The literature cites the large volume of vinasse that is generated but does not deeply discuss the correct control of the applied organic load rate (OLR) when feeding a biodigester, since the large water volume in the composition can change the organic content fed into the reactor at each batch.…”

Recently, new solutions have arisen to promote bioenergy expansion, some of which meet the requirements of reliability, sustainability, and governance. In Brazil, the Sao Paulo state (SPS) is characterized by strong agro‐industrial and livestock activities, which generates increasing residues in the last years with the potential to produce bioenergy and offer environmental and economic benefits. The Brazilian National Biofuel Policy (Renovabio) has been enhanced to seek sustainable development, encouraging new agribusiness research. Studies have shown that the sugarcane sector, a conventional ethanol and bioelectricity producer, has the greatest potential to produce biogas/biomethane, which can be maximized with the introduction of co‐substrates regionally generated from corn, soy, orange, coffee, poultry, and swine. This overview, based on the main SPS agro‐industrial and livestock residues, shows innovative alternatives for integrating anaerobic co‐digestion (co‐AD) processes through a regional strategy, by providing long‐term revenues and greenhouse gas mitigation, which would also spread the discussion for National and International prospects. This study discusses logistical, political, and financial aspects, revealing a promising business model supported by public policies. However, its feasibility requires a real economic assessment with the inclusion of decarbonization credits, and political subsidies for biomethane as a biofuel under the Renovabio, which will facilitate its insertion into the agro‐industry in the coming years.This article is categorized under: Policy and Economics > Energy Transitions Sustainable Energy > Bioenergy Climate and Environment > Circular Economy Policy and Economics > Regional and International Strategies
