Brazil ·
São Martinho is a Brazilian agribusiness group producing sugar, ethanol and bioenergy. It combines sugarcane cultivation and processing with ethanol production from corn, serving food, fuel and animal feed markets. Its operations include four mills: Usina São Martinho, Usina Iracema, Usina Boa Vista and Usina Santa Cruz. Alongside sugar and ethanol, it sells electricity and co-products, and it reports its sugarcane business by crop season rather than calendar year.
At the mills, harvested cane is crushed to extract juice, which is made into sugar or fermented into ethanol, while the fibrous residue is burnt to generate electricity. Corn processing produces ethanol together with DDGS, dried distillers grains with solubles, a protein-rich feed ingredient for livestock, and corn oil. These extra product streams come from the same fuel production process, which links the group to cattle and feed buyers as well as fuel and sugar markets.
Size of the business
São Martinho crushed approximately 21.7 million tonnes of sugarcane in the 2025/2026 crop season, as reported on 10 February 2026. This is the cane actually processed, not plant capacity or sugar output, and corn operations are reported separately.
Is ethanol produced only from sugarcane?
No. São Martinho also produces ethanol from corn.
Does the 2025/2026 crop season mean calendar year 2025?
No. The company reports by crop year, so the 2025/2026 season spans parts of both years.
