Historically, the predominant energy matrix has been based on burning firewood logs with manual feeding, a process that presents thermodynamic limitations, high ergonomic risks, and a severe dependence on seasonal labor. In this context, the present study aimed to analyze the technical and economic feasibility of replacing firewood with an automated wood chip system in a storage facility. The methodology was based on a comparative case study between the February 2025 and February 2026 harvests, which used firewood and wood chips, respectively. Data dispersion analysis was used to evaluate the thermal stability of the process, in addition to assessing the Technical Index per Dropped Moisture Point (ITpb - Índice Técnico por Ponto Baixado) for input consumption and the variation in operational costs (OPEX), consolidated through the Power BI tool. The results demonstrated that thermal automation stabilized the system, eliminating atypical operational failures caused by delays in manual feeding, which enabled a significant increase of 93.8% in the volume of processed soybeans. The thermodynamic performance, attested by the ITpb, proved an optimization in specific energy consumption, an advantage strategically leveraged by the complete elimination of the need to hire temporary workers (safristas) for furnace management. The operational scale gain, coupled with a substantial reduction in the payroll, resulted in a 46.8% decrease in the effective drying cost per grain unit (dropping from R$ 4.01 to R$ 2.13 per ton). It is concluded that the transition to wood chips transcends strict energy efficiency, configuring itself as a logistical modernization that ensures greater occupational safety and sustainable economic optimization for the agro-industry.

Low-quality fuels can cause engine failures, increase consumption, lead to higher pollutant emissions, and raise maintenance costs. Adulteration and the presence of contaminants such as water and heavy metals worsen these risks. Among the main fuels, gasoline is efficient for light vehicles but highly polluting; ethanol, a renewable fuel derived from plants, reduces greenhouse gas emissions; diesel, widely used in heavy vehicles and machinery, may be produced with low sulfur content to decrease pollutants; and biodiesel, obtained by transesterification of oils or fats, offers a cleaner alternative to fossil diesel. Ensuring fuel quality is therefore strategic for efficiency, sustainability, safety, and economic performance, contributing to the development of the energy and logistics sectors in Brazil and globally. The internship at the Q-Laboratórios fuel laboratory in Rio Verde, Goiás, enabled the monitoring of all stages of quality control for ethanol, gasoline, diesel, and biodiesel, from sample collection to issuance of conformity reports and analyses. Physicochemical tests were carried out according to ANP specifications, using specialized equipment to evaluate parameters such as color, appearance, density, alcohol content, flash point, water content, electrical conductivity, and biodiesel content. The 1 year and 6 months of experience highlighted the importance of laboratory rigor to ensure the quality and safety of fuels distributed in the region.

Stabilization ponds, widely adopted in Brazil due to their low cost and operational simplicity, present limitations in meeting stricter quality standards, particularly regarding turbidity and the final appearance of the effluent. In this context, the present study aimed to evaluate the efficiency of chemical polishing applied after secondary treatment in a Wastewater Treatment Plant (WWTP) located in Rio Verde, Goiás. Two coagulants commonly used in clarification processes were tested: polyaluminum chloride (PAC) and ferric chloride, seeking to determine which one offered the best technical performance. The analyses included physicochemical parameters such as pH and turbidity, as well as the visual assessment of the treated effluent, enabling objective comparisons between treatments. The findings not only contribute to improving the overall efficiency of the city’s wastewater system but also provide technical insights applicable to other regions with similar treatment structures, promoting more sustainable and effective practices in wastewater management.

The adopted methodology is based on the application of the DMAIC cycle (Define, Measure, Analyze, Improve, and Control), integrated with chemical production engineering, emphasizing automation, real-time monitoring, and standardization of operational routines. The results indicate high control over critical process variables, effective use of performance indicators, statistical control, and energy recovery, which contribute to maximizing meal yield and minimizing waste. Furthermore, the fundamental role of operator engagement and leadership in maintaining a culture of continuous improvement is highlighted. It is concluded that the systematic implementation of Lean Six Sigma constitutes a viable and effective solution for operational optimization, cost reduction, and compliance with environmental requirements, with potential for replication in other units within the agro-food sector.
