Cub Foods tests eco-friendly bags made from crustaceans

Following a model that has worked well for Lund's, Byerly's, Target, and Rainbow Foods, Supervalu Inc.-owned Cub Foods is now focusing on expanding its reusable bag program. Cub says the goals for the program, over the next few years, are to use more recycled material in its bags, make sure the bags are safe through more stringent toxin testing, and reducing the cost of the bags.

To meet those goals and produce more eco-friendly bags, Cub is working with Go Clean, a Santa Monica-based company that manufactures antibacterial, antimicrobial, lead-free reusable products, including bags, reports the Minneapolis-St.Paul Business Journal. The company's secret ingredient?

The bags are coated in chitosan, which is made by processing chitin, the main structural element in the shells of crustaceans such as shrimp and crabs. Chitosan has many commercial uses, mainly due to the chemical's ability to protect against the growth of fungi and bacteria.

If all goes well with testing, the bags will be sold in Cub Foods stores nationwide for $2.49 a pop.
