Bioeconomy

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.

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.

SteamBio – biomass residuals from rural areas as flexible raw materials for producing chemicals and energy

Biomass is the main resource of the bioeconomy. However, biomass has a low energy density and also needs to be used decentrally where it grows. A project group involving researchers from the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart and other institutions in Europe is addressing these challenges and demonstrating how biomass from rural areas can be made suitable for industrial processes.

Over the next four years the European UNRAVEL project will demonstrate a sustainable and economically feasible biorefinery for the conversion of second generation biomass into fuels, chemicals and building materials. In their efforts the partnership from six European countries are supported by the Bio Based Industries Joint Undertaking (BBI JU) which funds the UNRAVEL project with 3.6 million Euros.

Using ultrapure lignin from the lignocellulosic biorefinery at the Fraunhofer Center for Chemical-Biotechnological Processes CBP in Leuna, researchers at the Technical University of Hamburg-Harburg (TU HH) have produced lignin-containing aerogels and processed high-porosity insulating boards with excellent insulation properties. The lignin was recovered from beech residual wood at the Fraunhofer CBP using the Organosolv process.

Overview

Materials and chemicals

Biomass can be used to produce chemicals, fibres, pigments and plastics. These products are either identical to their petroleum-based counterparts or have completely new properties. Biorefineries will play a key role in the transition to a bioeconomy. There is great expectation placed on the potential ability to convert the countless carbon compounds in biomass into chemicals and material components.

Overview

Biobased resources

A major goal of the bioeconomy is to use larger quantities of biobased raw materials to produce energy, transport fuels and feedstock for industrial processes. This requires detailed analyses, simulations, concepts and processes. Major focus needs to be placed on issues relating to crop production, biomass potentials, land surface requirements, conversion technologies, biobased value creation networks and food security.
