TEFA & BABS - A process for the production of the sustainable industrial products TEFA (peat substitute) and BABS (natural foam) from corn straw.

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).

Key features

  • Substitution of peat by TEFA results in savings of 85% or 220 kg CO2 per m³
  • Production of TEFA will facilitate the conservation of valuable wetlands
  • The removal of corn stems from the fields has positive agronomic and environmental impacts


  • One TEFA & BABS production line can be amortized within 2 years
  • Mushroom growers can produce casing soil with a cost reduction of 30%
