Sugarcane reinvents itself, going far beyond sugar and ethanol. It becomes an essential platform for Brazil’s energy transition and bioeconomy, generating multiple renewable products.
Since its origins, sugarcane has demonstrated the potential of an agricultural crop to transcend the mere production of food or basic raw materials. Today, this versatility reaches new heights, positioning the sugarcane energy sector as a fundamental pillar for the future of clean energy and sustainability in Brazil and worldwide.
What was once a plant that generated sugar and fuel is now transforming into a true agricultural biorefinery. Its byproducts, once waste, are now valued as sources of electricity, biogas, biomethane, and, in the near future, even precursors for sustainable aviation fuels, boosting the country’s renewable energy matrix.
The Strength of Brazilian Production
Projections from Conab indicate a robust sugarcane harvest for 2026/2027, with an estimated 705.2 million tons, an increase of 4.7% compared to the previous cycle. With a harvest area of 9.1 million hectares and an average productivity of 77.9 tons per hectare, Brazil, especially the Southeast region led by São Paulo, reaffirms its position as a global giant in production.
However, the focus is not just on expanding cultivation. In a country with over 8.5 million km², where sugarcane occupies about 9 million hectares, the real challenge lies in optimizing the extraction of energy and value from each ton of biomass already cultivated, intelligently maximizing the use of existing resources.
Ethanol: An Essential Pillar
Sugarcane ethanol production is on the rise, with projections of 29.98 billion liters for the 2026/2027 harvest, a 9.7% jump from the previous season. When combined with corn-based ethanol, Brazil’s total production could reach an impressive 41.88 billion liters. This growth highlights the biofuel’s consolidation as one of the main drivers of Brazil’s energy transition in the transport sector.
Ethanol’s role in Brazil has changed drastically. From a complementary product to sugar, it has evolved into a leading renewable fuel. This transformation is driven by strategic policies, such as the increase in the mandatory blend of anhydrous ethanol in gasoline, which rose from 27% to 30% in August 2025 and, more recently, to 32% (E32) in July 2026, solidifying demand for the biorefiner and reducing dependence on fossil fuels.
Consumers also play a crucial role. In 2025, hydrated ethanol sales exceeded 19 billion liters in the first 11 months of the year. Millions of Brazilian flex-fuel vehicles use ethanol daily, replacing gasoline with a plant-based alternative, which reinforces the country’s commitment to transport decarbonization.
Undeniable Environmental Advantages
The substitution of gasoline with sugarcane ethanol has a significant environmental impact. This biorefiner has one of the smallest carbon footprints among liquid fuels used on a large scale. Brazilian government studies indicate reductions of 70% or more in greenhouse gas emissions compared to gasoline, depending on the methodologies applied.
A simulation from the RenovaBio program, for example, demonstrated that sugarcane ethanol emits 26 grams of CO₂ equivalent per megajoule, while gasoline emits 85 grams – a 69% reduction. The key difference lies in the origin of the carbon: ethanol releases carbon that sugarcane itself absorbed from the atmosphere, while gasoline introduces fossil carbon, trapped for millions of years. Although ethanol production is not entirely carbon-neutral, the final energy balance is highly favorable, with sugarcane producing significantly more energy than the fossil energy consumed in its production process.
The Biorefinery of the Future
The true revolution of sugarcane lies in its ability to generate more energy and value per ton of biomass. The plant has ceased to be merely a sugar and alcohol factory to become a complex biorefinery. Bagasse, once a residue, now generates electricity and powers the mills. The straw, left in the field, is now seen as a valuable energy reserve.
Vinasse, once an environmental challenge, is now utilized for biogas and biomethane production, in addition to enriching the soil with nutrients. Filter cake also integrates into this circular economy, providing nutrients and organic matter. This complete biomass optimization allows a single ton of sugarcane to produce sugar, first and second-generation ethanol, electricity, biogas, and biomethane, with the potential for future molecules for sustainable aviation fuels (SAF).
Brazil has a strategic advantage: a vast fleet of flex-fuel vehicles and an already consolidated fuel distribution infrastructure for ethanol. This eliminates the need to build new supply networks, accelerating the adoption of renewable fuels. Furthermore, RenovaBio, with its CBIOs (Decarbonization Credits), transforms the environmental benefit into economic value, further incentivizing emission reductions in the sector.
Sugarcane’s Legacy for Agribusiness
The biggest transformation may still be to come: the production of 2nd-generation ethanol from sugarcane fibers, bagasse, and straw. This will allow for an increased fuel supply without the need to expand cultivated area. The key question shifts from “how many hectares of sugarcane can we plant?” to “how much energy can we generate from each hectare already cultivated?”.
This paradigm shift elevates the economic and energetic value of the crop. EPE scenarios already foresee the expansion of biomethane from agro-industrial waste and the use of biorefiners in new applications, such as aviation. Thus, the sugarcane energy sector expands its impact beyond automobiles, reaching trucks, buses, industries, electricity generation, and renewable gas.
Sugarcane has become a model of the circular bioeconomy, demonstrating that the value of a crop lies not only in its primary product but in the ability to fully utilize all the biomass it generates. The agriculture of the future, inspired by sugarcane, will be one that maximizes the production of food, energy, and low-carbon molecules in the same area, paving the way for a more sustainable future.
