Cormo AG was founded by inventor Stefan Grass in Switzerland in 2015. A pilot production plant based in Alsace, France, went into operation in 2016. This pilot plant turns cornfield waste into a 100% sustainable peat moss substitute (TEFA) and foam products (BABS). With a significantly larger corn production volume in the United States (as well as significantly larger demand for sustainable products), Cormo AG has incorporated Cormo USA Inc. in a joint venture partnership with Sustainable Projects Group Inc. Sustainable Projects Group Inc. holds 35% of the outstanding capital of Cormo USA Inc.

Radio Interview on WBAA 

Cormo USA’s President of the Board, Stefan Muehlbauer, interviewed on WBAA radio as Cormo announces the selection of Indiana for the first production site. “We currently import all of the products that we use in the peat moss industry, and those can be replaced easily by the available corn in the United States,” says Muehlbauer. “Using just 19 percent of the corn harvest waste in the United States, we can go from a 100 percent importer to a 100 percent exporter.”  Click here to listen to the interview
