The Renewable Fuels Association (RFA) has updated its guidelines for quality control for ethanol plants. The group says the guidelines are an educational tool and information resource to help refiners make sure they turn out denatured fuel ethanol, distillers dried grains, carbon dioxide and corn distiller’s oil that meet customers’ expectations.

“This document underscores the commitment of the Renewable Fuels Association to help ethanol producers provide the highest product quality with the highest product integrity,” said Kristy Moore, RFA’s vice president of technical services.

The document details the basic principles for quality assurance and quality control including testing frequency, sampling, and record keeping. It also includes an expanded discussion on all of the major products being produced at an ethanol manufacturing site: denatured fuel ethanol, distillers dried grains, corn distillers oil, and carbon dioxide.
