What are the compostable bags made of? Do they contain genetically modified organisms (GMOs)?
BioBags are made in San Leandro out of Mater-Bi™, a resin manufactured in Italy out of starches, glycerines, and other materials that come from corn (it may also contain some canola- and sunflower-derived products). Mater-Bi is certified GMO-free by a European third party certifier. Mater-Bi is currently not manufactured in the United States because GMO-free corn is not available here.
