CORMO has developed and patented the process for using maize straw and producing TEFA and BABS. Production-scale solutions for raw material harvesting and processing have been tested for several years.

The result is a modern, economically attractive production process with consistently high product quality. CORMO offers licensing agreements for its process and the related production know-how and experience.

The raw material maize straw

Maize straw is unsuitable as litter for animal husbandry, as feed and as fuel. It, therefore, remains worldwide as crop residue on the field and is plowed under. CORMO uses only the stems for the production of TEFA and BABS, all other straw components remain on the field. The CORMO utilization regime does not affect grain production and harvest, and grain maize remains a humus-positive crop.

The use of the raw material maize straw requires cooperation between the farmer, the contractor and the processor. This cooperation offers income opportunities for agricultural production partners.

The processing method

The process engineering solutions and machines were tested and optimized by CORMO over several years of development work. In addition, a control system was designed and implemented, which ensures the optimal adjustment of the process parameters to the required product quality and enables online monitoring of process data. CORMO has set up its own production facility in Alsace (France) and has appropriate operating experience. The production is largely modular and can be expanded accordingly.

The commercial replication of the process requires a raw material potential of 1’000 to 5’000 ha per site.


Peat is a fossil resource similar to coal. Its exploitation and use generate the emission of 250 m3 of CO2-equivalents per m3 of peat. The replacement of peat with TEFA reduces these CO2 emissions by 85%. This advantage of TEFA has been proven in a life cycle analysis conducted by the Zurich University of Applied Sciences.

The removal of peat is also associated with the destruction of moorland. Moorlands cover only 3% of the global land area, but they bind twice as much CO2 as the total forest area. In addition, moorlands are habitats of many endangered plants, insects and migratory birds. 

The Raw Material Maize Straw

The raw material corn straw is available worldwide in enormous volumes – its utilisation enables farmers and machine contractors to earn additional income.

Processing Method

The processing method involves the storage of stable intermediary production and thus an optimal utilisation of the required machines throughout the year. Through the state of the art data generation and process control, the principle “intelligence inside” is applied.

Environmental benefits

By replacing peat, large amounts of CO2 emissions are avoided, ecologically valuable moorland can be conserved, and transportation routes to the end consumer are shortened.
