Brazil's Ministry of Agriculture and Livestock has introduced the country's first official identity and quality standard for dried distillers grains (DDG), the main co-product of corn ethanol production, in a move aimed at strengthening the corn ethanol industry and expanding market opportunities.
The new regulation establishes official criteria for the identity, quality, classification and labeling of DDG. It also defines terms related to biorefineries and industrial plants that produce ethanol from corn and other grains, Datamar News reported.
According to the ministry, the standards are expected to strengthen Brazil's corn ethanol supply chain by making DDG easier to trade in domestic and international markets while creating new business opportunities for biorefinery co-products.
The ministry said the regulation will improve inspection systems, increase legal certainty and provide greater predictability for producers, processors and buyers.
DDG is widely used as a protein- and energy-rich ingredient in animal feed, particularly for beef and dairy cattle. With official standards now in place, the product is expected to gain greater credibility and traceability, both of which are important requirements for access to international markets.
The regulation is also expected to benefit corn ethanol plants by providing a clear technical framework for classifying and marketing DDG. This is likely to reduce information gaps and lower the risk of commercial disputes.
The move comes as Brazil continues to expand corn ethanol production, particularly in the country’s Centre-West region. As DDG is a high-value co-product, more efficient marketing could improve returns for ethanol producers.
The standardization is also expected to make Brazilian DDG more attractive to overseas buyers by providing clear quality and origin assurances. In the domestic market, DDG could see wider use in animal nutrition as a partial substitute for corn and soybean meal, helping livestock producers reduce feed costs.
For the livestock sector, DDG is considered a valuable feed ingredient because of its high protein and phosphorus content and its digestible energy value. The official classification is expected to give farmers greater confidence in the product by providing clear technical specifications.
The regulation also covers other biorefinery co-products, including wet distillers grains (WDG), and is expected to support the development of regional markets by improving logistics and making price discovery more transparent.
The ministry said the new standards will also strengthen Brazil’s DDG export prospects by reducing technical trade barriers, increasing confidence among international buyers and improving the competitiveness of the country’s corn ethanol industry.
