A peat substitute for use as casing soil in the mushroom industry

Thanks to its two innovative products made from corn straw, CORMO AG aims at replacing the consumption of peat, a fossil resource similar to coal, generating up to 250 m³ CO2 equivalents per m³ of peat.

The company has developed a patented process that can produce the products TEFA and BABS from corn straw residues. TEFA is a full-fledged peat substitute and is ideal as a structural material in plant substrates as well as cover soil for mushroom cultivation. By replacing peat with TEFA , the CO2 emissions associated with peat consumption are reduced by 85%, ecologically valuable peatlands are spared and the transport routes to end-customers are shortened. BABS has similar characteristics as charcoal, polystyrene or superabsorber polymers. The unique properties of the material enable new applications in the areas of plant substrates (extension of casting intervals), buildings insulation and exhaust air purification (removal of ammonia from animal husbandry).
