“…Similar to S1, a surplus electricity of 96% could still be sold in order to generate additional revenue in the current scenario. Compared with other agroindustrial sectors, Ferraz Junior et al [64] reported average values for electricity generated from biogas in a sugarcane plant, reaching 0.015 MWh per sugarcane ton, being lower than the value obtained in this study with 0.6 MWh per green coffee ton.…”

“…This suggests that biomethane is not as energy efficient, but it generates a lower environmental impact by compensating for this energy difference. Moraes et al [67] indicated the potential to replace 40% of the diesel used in agricultural machinery in the sugarcane agroindustry and, according to Ferraz Junior et al [64], the potential for biogas production by sugarcane plants and landfills in the State of São Paulo can replace up to half of the diesel consumed in the state. These data corroborate the importance of replacing fossil fuels such as diesel in Brazil with biomethane.…”

Coffee processing generates a large amount of organic waste, which has the potential for energy use through biogas production. Although Brazil dominates world coffee production, treating its residue with biogas technology is not a practice, especially due to this product’s seasonality, which hampers continuous digester operation. The implementation of biogas production from coffee residues in a concept of industrial symbiosis could overcome this. This work evaluates the biogas energy potential from the main liquid residues of coffee processing (i.e., mucilage and wash water) and their integration with glycerin and cattle manure. Around 2773 m3 biogas day−1 would be produced (75% CH4), used as biomethane (734 thousand m3 year−1), or thermal energy (23,000,000 MJ year−1), or electricity (2718 MWh year−1), which could supply, respectively, all the liquefied petroleum gas (LPG) and diesel demands of the farm, all the thermal energy demands of the grain drying process, as well as electricity for 30 residences. Considering the short coffee season, the results have a broader context for the application of biogas production on coffee processing farms, envisaging that the Agroindustrial Eco-Park concept has the potential to integrate various agroindustrial sectors for energy production, residue exchange, and water recirculation.

Climate change has taken center stage in international debate in recent years. In this circumstance, several agreements and frameworks were established to reduce pollution and environmental degradation. For instance, the 2016 Paris Agreement was established to set goals to reduce greenhouse gas emissions at international and national levels, respectively. In the climate change context, the bioenergy sector has gained significant importance as a sustainable alternative to fossil fuels. In Brazil, sugarcane presents an opportunity to replace fossil fuel with sugarcane byproducts and wastes, increasing renewable energy generation. In recent years, ethanol production waste, known as vinasse, has gained popularity due to its potential to generate biogas. This residue has a high energy content and is an excellent substitute for fossil fuels. In addition, vinasse biogas presents two possible applications in the sugarcane sector: electricity generation and diesel replacement. Given this, the sugarcane industry can potentially increase its participation in the energy sector beyond bagasse and straw, byproducts already used as renewable energy sources. Thus, it is necessary to evaluate the impacts of biogas insertion in the sugar and ethanol sector. This research aims at studying the alternative of switching fossil fuel use to vinasse biogas in sugarcane truck fleets. The primary tool used in this study was the portfolio theory. The optimization model was built, including investment costs from biogas production and diesel replacement and revenue generated from Brazilian carbon credits (CBIO), seeking to minimize the risk, measured through Conditional Value at Risk (CVaR), for a given return. In this model, the role of biogas is analyzed considering a hypothetical plant, and results show a positive economic impact of biogas production. Results show that the CBIOS market incentivizes a higher rate of diesel-to-biogas substitution, leading to positive environmental implications. Portfolios with CBIOS achieve nearly 100% diesel substitution, compared to around 80% in scenarios without CBIOS. However, the investment strategy of the model varies depending on the profit range. In the profit range of R$131 to R$152 million, the model focuses on biogas generation and converting diesel engines to biogas. Within higher profit ranges, the model shifts the allocation of vinasse biogas for electricity production as the need for profit increases and prioritizes an increase in sugar production.

“…Os principais custos estão relacionados aos transportes das biomassas e do próprio BM, bem como nos custos de investimento. Assim, a otimização logística é uma forma eficaz de minimizar o custo de modelos de negócio de BM (WU et al, 2015;FERRAZ JR et al, 2022). Dentro deste contexto, este trabalho explora a literatura para compreender os modelos que estão sendo utilizados que facilitem a transição do setor de GN.…”
