# Corn ethanol expands, but sustainability remains a challenge

> Brazil’s corn ethanol industry is expanding, with production largely using second-crop corn grown after soybeans and generating dried distillers grains (DDG) for livestock feed. The article describes concerns over land use, deforestation-linked boiler fuel, and the possibility that export markets will demand tighter supply-chain controls.
