“…The prototype was installed on a farm located in Herculândia City, São Paulo State. To speed up the biodigestion process, the prototype was buried so that the temperature was kept between 25 and 35°C, since the temperature influences the decomposition of organic matter and the amount of methane (CH 4 ) present in the biogas (Mota et al, 2019).…”

The increase in agricultural production generates a large volume of waste, which may lead to concerns about its proper destination. The main economic activity in Herculândia City, Western region of São Paulo State, Brazil, is the production and processing of peanuts. In this process, a large volume of peanut shells is generated. Following the current movement of using waste for energy purposes, in compliance with what was established by the Sustainable Development Goals (SDGs), this work aimed to carry out a study on the biogas potential generated from peanut shells. To this end, a low-cost biodigester prototype was built, which, over a period of 108 days, produced biogas and biofertilizer. The results showed that there was production of biogas from peanut waste; however, the volume produced did not provide savings in electricity costs when compared to the production of biogas from animal waste. Nevertheless, the work demonstrated the importance of providing solutions to the disposal of peanut shells, effectively mitigating future environmental problems, and serving as an alternative for generating sustainable and low-cost energy, especially for small producers.

This study aims to present the time behavior of wastewater flow parameters, organic matter, biogas flow, biogas composition, and its relations, measured through online sensors, in a municipal wastewater treatment plant (WWTP) operating full-scale upflow anaerobic sludge blanket (UASB) reactors, installed in the south of Brazil. WWTP has online measurement devices to evaluate some physicochemical variables of the sewage and the biogas. The COD analyzer (UV– Vis probe), ultrasonic flow meter, biogas flow meter, and biogas composition analyzer were the equipment used. The monitoring occurred for two time periods each of 72 h and one time period for 48 h in the year 2018. Data were checked with descriptive statistics, data independence was checked through the autocorrelation Box– Ljung test, normality behavior was checked with several tests (Shapiro– Wilk, Kolmogorov–Smirnov, Lilliefors, Anderson–Darling, D’Agostino K2, and Chen–Shapiro), and Spearman’s correlation coefficient was used to evaluate the correlations among the parameters. The mean sewage flow was 345 ± 120 L.s-1; removed organic load was, in average, 48%; biogas quality values were 82.32% ± 3.62% v/v (CH4), 2.66% ± 1.19% v/v (CO2), and 3453 ± 1268 ppm (H2S); and the production per capita obtained was 4.51 ± 1.65 NL.hab-1.d-1. It was estimated an electric power generation of 3118.6 kWh.d-1, which is equivalent to an installed power of 130 KW. The behavior of removed organic load and biogas flow (Nm3.h-1), produced in the treatment plant, showed variable, periodic, and nonstationary time behavior.

O aterro sanitário é uma técnica de disposição de resíduos sólidos ainda muito utilizada em países em desenvolvimento, como o Brasil. Entretanto, sua operação pode ocasionar vários impactos ambientais negativos como a contaminação das águas subterrâneas, sendo assim, é necessária a realização de monitoramento ambiental. Diante disso, este trabalho teve como objetivo avaliar a qualidade da água subterrânea em área de aterro sanitário localizado na região metropolitana de Fortaleza/CE no decorrer do tempo. Para obtenção dos dados foi realizada uma consulta a Superintendência Estadual do Meio Ambiente para análise dos laudos de licenciamento ambiental. Foram identificados 3 poços a montante e 3 à jusante do aterro. Os parâmetros foram selecionados conforme a maior periodicidade de dados, sendo escolhidos 30 parâmetros. Foram captados os dados de 12 coletas realizadas entre novembro de 2018 à março de 2023. Os parâmetros foram analisados em dois grupos, montante e jusante, utilizando o teste de Normalidade Shapiro-Wilk, ANOVA e Kruskal-Wallis com intervalo de confiança de 95%. Os parâmetros com diferença estatística significativa foram comparados com os valores de referência de consumo humano da Resolução CONAMA n° 396 (2008). Dentre os parâmetros analisados, apenas a condutividade, os cloretos, pH e molibdênio apresentaram maiores valores a jusante com diferença estatística significativa. Pelo período e parâmetros considerados neste estudo, o Aterro Sanitário Metropolitano Oeste de Caucaia (ASMOC) não interferiu na qualidade da água subterrânea, com exceção do parâmetro cloreto. É importante a caracterização da água subterrânea antes da implantação do empreendimento para que se obtenha valores de referência da qualidade natural da água.
