Summary: During the 2000s, the Brazilian sugar-ethanol sector experienced growth due to the development of flex-fuel vehicles and rising international commodity prices. However, this growth also increased pressure on land -use change and management. This study examines the efficiency and productivity of the sugar-ethanol industry and suggests that small SE mills could benefit from merging with larger mills to improve their productivity and contribute to environmental policies in Brazil.

Summary: Sugarcane has become an important renewable raw material that can potentially reduce greenhouse gas emissions and decrease the dependence on fossil fuels. Brazilian government policies have created favorable conditions for the establishment of the first sugarcane biorefinery, which aims to produce biofuels, sugar, and bioelectricity in a sustainable and cost-effective manner. The development of 2G and 3G technologies further expands the potential of sugarcane for producing value-added biochemicals and reducing emissions through integrated systems with a non-waste vision and circular bioeconomy.

Summary: The study assesses the impacts of ethanol-driven sugarcane expansion on agricultural and hydrological drought in Brazil, revealing higher risks of drought in the Central West and Southeast regions, which could lead to significant agricultural losses and water scarcity issues. Policy makers can use this information to take precautionary measures to mitigate the negative hydrological impacts of increased ethanol demand.

Summary: This study conducted a failure analysis of hammers from a sugar-alcohol industry shredder in Brazil, revealing that the ferrous coating exhibited superior resistance against wear while 410 stainless steel performed better against corrosion. However, the coating was susceptible to corrosion, leading to detachment and subsequent severe abrasion and corrosion.

Summary: The mapping and changes of sugarcane plantations are important for the economy and environment, especially in the biofuel industry. This study evaluates two approaches to address the challenge of mapping sugarcane abandonment in a region dominated by smallholders in Brazil. Using Landsat imagery and temporal analysis, the study reveals the spatial and temporal patterns of sugarcane abandonment and provides a necessary database for further research on the underlying causes.

Summary: The study found that the impact of straw removal on soil health can be effectively detected through SMAF scoring curves, with sandy soils being more susceptible to soil degradation. Low and moderate levels of straw removal have minimal adverse effects on soil health, while total and high levels of straw removal lead to significant soil degradation. Soil health is closely related to sugarcane yield.

Summary: Bioenergy, specifically sugarcane electricity, is highlighted as a key player in reducing greenhouse gas emissions in Brazil. Utilizing sugarcane bagasse and straw for electricity production holds great potential for mitigating climate change. By improving cogeneration systems and recovering straw based on suitability maps, it is estimated that up to 13% of GHG emissions from the electricity sector in Brazil could be avoided.

Summary: The use of Geostatistics in agricultural sciences, particularly in sugarcane cultivation in Brazil, has proven to be beneficial in optimizing production processes and reducing negative environmental impacts. However, there is a heterogeneity in the distribution of Geostatistics research in sugarcane plantations in Brazil, which could be attributed to legal restrictions or inadequate research dissemination.

Summary: The failure mechanisms of superheater tubes in a sugarcane industry were investigated, and different failure mechanisms were identified on the steam and fire sides. Sodium chloride and iron oxide compounds deposits were found inside the tubes, which could be attributed to carryover or primming. A spherical iron particle was formed by local melting of the tube's internal surface, and the external surface of the tube bulged due to excessive deposits accumulation caused by improper maintenance of Estamine.

Summary: The study evaluated the recent upgrade of APSIM-Sugar for the most cultivated Brazilian variety under water-limited conditions and projected the potential impacts of future climate changes on sugarcane crop performance. Results indicated that cane yields would decline in rainfed areas due to increased water stress and slightly decline in fully irrigated sites. The future projections showed variability between climate models, with large uncertainty towards the End-of-Century period.

Summary: This article presents a comprehensive model for the industrial production of methanol through the direct hydrogenation of biogenic CO2 from a biorefinery. The carbon capture and transformation process is simulated, ensuring the use of renewable H2 and electrical power. An environmental assessment is conducted through a life cycle assessment study, applied to a typical sugar-ethanol complex in Argentina. The results demonstrate that producing green methanol is a viable option for decarbonizing the industry and the methanol market. However, the sustainability of the overall process heavily relies on the sustainability of the agricultural tasks in the biorefinery, which is often neglected in environmental studies on CO2-based product production.
