Digestion and fractionation processes for holistic use in biorefineries

The main aim is to establish processes for biorefineries in Germany and throughout Europe.

The focus is on digestion and fractionation processes

  • material containing lignocellulose, such as wood or straw.
  • and alternative processing lines for oilseeds.

We develop the processes on a laboratory scale and scale them up for transfer to pilot scale. In the field of biomass fractionation, we are developing new technologies and innovative processes for processing lignocellulose, polysaccharide and oil-containing substances in order to enable the holistic use of biomass, increase added value and obtain high-priced end products.

Biorefinery pilot plants at the Fraunhofer CBP

The following links will take you directly to the corresponding pages on the website of the Fraunhofer Center for Chemical-Biotechnological Processes CBP, our branch in Leuna.

 

Lignocellulose biorefinery

A specially developed integrated pilot plant is available for the pulping of lignocellulosic raw materials and their fractionation into the basic chemical components lignin and sugar or fibers. The plant enables digestion with organic solvents under increased pressures and temperatures, known as organosolv technology.

 

Oilseed biorefinery

Here, the mild EthaNa process is used to process oilseeds, which is operated at ambient pressure and a maximum of 70 °C to prevent denaturation of the proteins and other quality-reducing reactions. It enables holistic utilization of the raw materials and higher-quality product fractions compared to conventional processing.

 

Further information at Fraunhofer CBP

The Biomass Fractionation group of the Regenerative Resources innovation field works entirely at the Fraunhofer Center for Chemical-Biotechnological Processes CBP, our branch in Leuna. You can therefore find further information on equipment, research focuses and current projects on the Fraunhofer CBP website under "Raw material processing".

November 2022 – October 2026

Like-a-Pro

Alternative proteins for everybody and everywhere

Healthy and sustainable food – is this possible? The European Like-A-Pro project deals with the production of food from sustainable resources, and simultaneously the understanding of the consumer’s affections and needs that have to be satisfied to render the European dietary more healthy and in harmony with nature.

DaerPa

Insulation material from rapeseed hulls and biobased epoxy resin

When dehulling oilseeds, the hulls accumulate as a by-product. In the DaeRpa project funded by the state of Saxony-Anhalt, an innovative approach to using rapeseed hulls as an insulating material is being investigated. To this end, the rapeseed hulls are to be covered with a biobased coating to improve their stability and their flame-retardant effect.

 

September 2017 – February 2022

Ethana

Piloting the ethanolic native extraction of peeled rapeseed

In the “EthanNa®” joint project, cell disruption of rapeseed and recovery of valuable materials are carried out with ethanol instead of the usual solvents ensuring a higher quality of the products. In addition, the mild EthaNa process makes possible to isolate novel recoverable substances. The project's objective is the establishment of a pilot plant at the CBP.
