- Abstract
Every year, 10 million tonnes of chaff are available for recovery as residual material in Germany alone. Based on an innovative harvesting process that enables the recovery of the uncleaned grain in a mixture of chaff and chopped straw, the chaff can be put to a value-adding use in the form of the novel biomass mixture SpreuStroh (chaff-straw). In this paper, various processing options and thus possible uses of the chaff-straw mixture are presented. Based on an extensive characterisation of the SpreuStroh, possible applications for the farmer are shown. The system-related removal of weed-seeds and thus the reduction in the use of pesticides represents a particular benefit for the environment. Further processing of the chaffstraw mixture reveals higher-value potential uses, such as use in 3D printing or as an additive in fibre-plastic composites.
