Ilsa start biomass characterizations Life biopol project is entirely focused on the re-use of agro-industial and leather by-products. Ilsa has selected the following raw materials for biopolymer syntheses: Plant derived matrices: leguminous crop, cereals, sugar crane and sugar beet Animal derived matrices: hides and skins from tannery (wet blue) Vegetable biomasses are suitable sources of compounds of the carbohydrated family. While animal derived biomasses are known to have a high content in essential amino acids. For the first analytical screening and characterization, the selected raw materials we five: four raw materals from soybean one raw material from corn The biomass characterization will be performed using the official anatytical fertilizers methods according to the Itilian regulation (D.Lgs.75/2010) or other specific methods.
