“…The results were promising when compared to the study conducted by Leite et al (2014) that when using typically vegetable waste, in addition to sewage sludge, a removal of 51% of COD was obtained. In contrast, Gueri et al (2018) obtained a reduction of 80.98 -81.63%, using food waste and anaerobic sludge in bench reactors. Talha et al (2016) working with sugarcane bagasse, obtained a COD removal of 69.64%.…”

The grape industrialization process produces large volumes of solid organic waste, with the grape bagasse being the main waste generated in the winemaking process. Anaerobic digestion can be used to treat and dispose of agro-industrial biomass waste. The objective of this study was to evaluate the effect of the inoculum/substrate ratio on the Biochemical Methane Potential (BMP) of grape marc. The experiment was performed in laboratory scale through a system of reactor bottles in batches, removing a set of triplicate flasks for sampling and analysis every 48 hours, with the test lasting 12 days. The reactors contained residue, inoculum and 20% of nutritive solution, maintaining 20% of headspace. The reactors were incubated in an incubator at a mesophilic temperature (35 ± 2°C) and shaken manually every 24 hours. Three different inoculum/substrate (I/S) ratios of 0.75, 1.5 and 3 were used to evaluate the methane yield, organic removals and at the end of degradation the morphology of the bacterial community was evaluated by means of scanning electron microscopy. The I/S 3 ratio provided the best results for loading anaerobic systems, indicating that grape marc presents potential for biological treatment through anaerobic digestion.

“…Consistent with Gueri et al (2018), food residues have a good potential to produce biogas since they present values above the average of most substrates when evaluating specific methane production. The estimation of this generation can be done through experimental studies carried out in bench reactors such as the biochemical methane potential (BMP) test.…”

Due to the increase in human damage caused to the environment, there is a need for remediation measures and techniques to be applied in favor of a sustainable future for upcoming generations. One of the sectors that have potential in the use of low carbon economy stocks is agribusiness. In fact, part of agribusiness is fruit growing which is one of the sectors of greatest Brazilian economic prominence, with a wide variety of crops produced throughout the country and in different climates. In the food production chain, there are several post-harvest losses and the consequent generation of large amounts of waste. Anaerobic digestion presents itself as an excellent and promising option for the treatment of food waste, contributing to the fight against the increase of polluting emissions and generating biogas for use as thermal or electric energy or even as a fuel to replace fossil fuels. The anaerobic digestion of organic waste is a biological process characterized by the absence of oxygen which through the metabolic activities of microorganisms causes the complex organic material to be converted mainly into methane and carbon dioxide. In a scenario where the production of waste around the world is growing more and more, efficient waste treatment techniques are essential to ensure lower greenhouse gas emissions in the environment. In this study, the biodegradation capacity of the substrate formed with “ponkan” and “montenegrin” tangerine peels was investigated through BMP (Biochemical Methane Potential) tests with the determination of water content, total solids, and volatile solids in samples of laboratory under ideal conditions of pH, temperature, and humidity. The tests were carried out over a period of twenty-one days, having been found, in general, a greater production of gas until the twelfth day of testing, with a gradual reduction until stabilization around the twentieth day. The results obtained in laboratory show that there is a positive potential in the generation of biogas using tangerine peels in relation to the peels of other fruits researched in the literature (orange, banana, among others), with a biogas generation potential of 615.38 NmL/gSV for “ponkan” tangerine peel and 565.84 NmL/gSV for “montenegrin” tangerine peel. Brazil, due to its vast territorial extension and favorable climatic conditions, stands out in the international agricultural market and, therefore, holds great potential in the scenario of energy change. Despite the high potential of waste generated in the country, technologies for recovering organic matter are still incipient and even unknown. The results of this research are yet another contribution to reaffirm and publicize the benefits of treating organic matter via anaerobic digestion, with significant economic, social, and environmental advantages.

“…The internal pressure of the flasks was converted into volume of the generated biogas by Equations 1 and 2, for the different sweet potato genotypes evaluated and transformed to the normal conditions of temperature and pressure (CNTP) (Harries et al, 2001). This procedure was performed by Alves (2008), Gueri (2018), recommended by Angelidaki et al (2009) and reported by Alzate et al (2012).

Biogas is a technology that enables the generation of energy through the process of anaerobic biodigestion, and sweet potato is an option as an energy production source. This research evaluated biogas production in anaerobic biodigesters and characterized the physico-chemical composition of two commercial sweet potato cultivars, BRS Cuia and BRS Rubissol, and two genotypes, Bela Vista and Laranjeiras. Variance analysis, the Tukey test and the physical-chemical characterization were completed, and the results were correlated using principal component analysis (PCA). In the analyses of tuberous root composition, significant differences between the genotypes were observed because of the influence of the absorption of moisture, decomposition, and variations in the yield and quality of roots. For the biochemical methane potential (BMP) test, the estimate of biogas production was 2,906.5 liters ha-1 for the cultivar BRS Cuia, 2,712.4 liters ha-1 for Laranjeiras, 2,906.5 liters ha-1 for BRS Rubissol, and 398,2 liters ha-1 for Bela Vista. The PCA analysis of sweet potato genotypes, physical-chemical and agronomic parameters showed all genotypes have a direct correlation with the amount of reducing sugars and humidity, with 97.77% of the data variability explained. The Laranjeiras genotype has the most significant potential to produce biogas, followed by the BRS Cuia cultivar. The results emphasize that the sweet potato crop is a good source of biomass for energy generation.
