Bioeconomy

Textiles are a given in civil engineering. Until now, textiles made of resistant synthetic fibers have been used for this purpose, having a long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade when it has done its job. Natural fibers, in contrast, often decompose too quickly. The DITF are developing a bio-based protective coating that extends their service life.

A novel, both environmentally friendly and cost-saving process for the production of carbon fibers from lignin has been developed at DITF. It is characterized by high energy-saving potential. The avoidance of solvents and the use of natural raw materials make the process environmentally friendly.

The annual highlight of the industry is the International Conference on Cellulose Fibres in Cologne (www.cellulose-fibres.eu), where the latest innovations were showcased last week: new cellulose fibre technologies for various feedstocks and a wide range of hygiene and textile products as well as alternatives to plastics and carbon fibre for lightweight constructions.

Bioeconomic model project: vanillin from process industry residues

Extracting vanillin from lignin dissolved in black liquor and developing it into a process that can be scaled up for industry is a bioeconomic approach that researchers at Biberach University of Applied Sciences and Ulm University are pursuing in a five-year project.

Coffee capsules: wood instead of aluminium

In Germany alone, around three billion disposable coffee capsules made of aluminium and plastic are sold every year. This creates a gigantic waste problem, as only a small proportion of the capsules can be recycled. Fully compostable wooden coffee capsules might be a solution to this problem. The capsules have been developed by a start-up company called rezemo, which also has other biobased packaging solutions in the pipeline.

A vision: insect biorefineries as components of a sustainable bioeconomy

Eco-friendly and responsibly manufactured products are more in demand than ever before. Specific research is being carried out into materials and applications for a wide variety of uses. The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB is working with Hermetia Baruth GmbH on the vision of an insect biofactory that uses waste materials to produce a wide range of products such as biosurfactants, animal feed or foils.

Biocarbon fibres made of lignin

Carbon fibre is increasingly found in airplanes, cars and wind turbines. Carbon fibre is still made from oil and relatively expensive. However, this is soon to change. Researchers from the German Institutes of Textile and Fibre Research in Denkendorf (DITF) are working on the development of cost-effective carbon fibre made of lignin, a by-product of papermaking.

Lignin – a natural resource with huge potential

Petroleum is the raw material for basic chemicals. Growing demand and dwindling resources mean that the chemical industry is increasingly focusing on renewable resources. Lignin is a wood component that is proving to be a promising resource. It is currently almost exclusively used for generating energy, although it could also be used for other purposes. In Baden-Württemberg, a research consortium is specifically focused on exploring its…
