Cultivation and environmental protection
As a result, cattail is predestined as a raw material for industrial use. Typha crops are robust, natural monocultures that produce 15 to 20 tons of dry matter per hectare every year (about 150 - 250 m³ of building material). This corresponds to four to five times the amount native coniferous forests provide. If typha is cultivated as a raw material on Germany's lowland moor soils and valley floors (as nutrient traps, carbon sinks and erosion barriers, for water retention and biotope formation), this would be enough to cover the total demand for insulation and wall building materials. The feasibility of cultivating typha was demonstrated in the project “Cultivation of cattail in fens”, funded by the German Federal Environmental Foundation (DBU) and headed by the Chair of Landscape Ecology at the Technical University of Munich (1998-2001).
