REPLACEMENT FOR PEAT AND REDUCTION IN CO2 EMISSIONS

In corn cultivation, the stalks are generally unused. Sorba’s new process does not just use the spongy tissue from the stalks as an ammonia filter – the company goes one step further: Sorba has developed an application for the outer layer of the corn stalk that encases the spongy tissue inside. This outer layer is mechanically shredded and, under the name of TEFA, used as a substitute for peat, whose depletion leads to the destruction of moorlands and – since these are important CO2 sinks – the release of large quantities of CO2. With TEFA, the company is contributing to the replacement of a fossil raw material whose

mining is illegal in Switzerland, but which is still imported in significant quantities. For the past two years, TEFA has been marketed in Switzerland by a wholesaler as a component of peat-free compost. The innovative recycling of corn stalks is of interest for all corngrowing regions. In addition to the domestic market for this Swiss cleantech innovation, Stefan Grass is particularly looking to Germany, the Netherlands and France as export countries. With his company, he shows how marketable products can contribute to air pollution control and resource conservation.
