Flame retardant biopolymer fibers for an innovative bioeconomy

Duration

01.10.2022 - 30.09.2024

The bioeconomy makes an important contribution to society through the use of non-fossil raw materials. Fossil resources interfere with the ecological cycles of our planet and thus shift established equilibria. One of the consequences of this is the climate crisis. However, there is another reason to push the move away from fossil products: they are finite. One example is phosphorus. "Peak phosphorus" is considered one of the most urgent resource problems. On the other hand, many phosphates remain unused in residual streams such as manure, sewage sludge or food industry residues.Nitrogen and phosphorus can be used to produce fertilizers and also flame retardants (FSM). FSMs are intended to inhibit and, in the best case, prevent the combustion process.The aim of the project is to develop value-added products, namely flame retardant coatings for the textile industry, for the bioeconomy from the N and P bound in biomass residues. If compostable fibers can also be coated with the flame retardant, the nutrient elements P and N will be returned to the soil after use. In this way, the nutrient cycle can be closed again.
