A joint marketing alliance between Renew Energy LLC, Wisconsin’s newest and largest ethanol plant, and Airgas Inc. has been announced, which will enable Airgas Carbonic to market beverage-grade liquid carbon dioxide co-products from the plant.

Airgas Carbonic is the second-largest manufacturer and distributor of liquid carbon dioxide in the US, with 6 production facilities. Of these plants, 2 are the largest in North America and offer state-of-the-art production and quality control capability, while the company also sources liquid carbon dioxide from other sources to augment its production.

“Renew Energy's ethanol plant 50 miles from Milwaukee will be an ideal source of beverage-grade liquid carbon dioxide for our food and beverage bulk customers. It will add to our network of sources in the Midwest,” said Phil Filer, president of Airgas Carbonic.

Renew Energy plans to begin production the week of 5th November at its 130 million gallon-per-year ethanol plant. The plant will feature the world's largest dry corn fractionation mill, yielding a completely different set of co-products than traditional ethanol plants and will use state-of-the-art environmental technology, capturing carbon dioxide and minimizing emissions well below regulatory limits.


Scott Busch, director of co-products marketing for Renew, noted that Airgas has the ability to market liquid carbon dioxide from 2 Wisconsin liquid carbon dioxide plants and commented, “Liquid carbon dioxide customers will be pleased to learn that Airgas Carbonic will have double the normal storage capacity at Renew Energy, plus back up sources to help provide uninterrupted supply.”

Airgas, Inc, through its subsidiaries, is the largest US distributor of industrial, medical, and specialty gases, and hard-goods, such as welding equipment and supplies.
