Starting September 2019, KNAUER is part of the EU funded IMPRESS research program, standing for “Integration of efficient downstream processes for Sugars and Sugar alcohols”. The research program, which is driven by a consortium of ten member companies and research institutions, received a total grant of 13 million Euros, with the goal to advance the sustainable production of chemistry raw materials.
Over the course of four years, the IMPRESS team aims to demonstrate a new kind of biorefinery, which allows converting plant-based non-food materials into important base chemicals. This next-generation biorefinery is designed to neither compete with world food production directly, nor for the involved resources. KNAUER’s role in the IMPRESS consortium is to contribute with its expertise and liquid chromatography purification technology, including the very efficient continuous separation technology simulated moving bed (SMB) chromatography.
KNAUER Simulated Moving Bed Systems
Simulated Moving Bed (SMB) is a method in process chromatography that enables substance mixtures to be continuously separated and extracted in two fractions.
Its efficiency is significantly higher than batch chromatography, through better utilization of the column stationary phase. This helps maximize productivity, while delivering unparalleled separation.
Earlier, KNAUER participated in the EU funded “Valor Plus” research program which also focused on technologies to create new biorefinery processes to utilize the whole plant by valorizing by-products, in contrast to today’s biorefinery which basically makes use of the crop only (European Union’s Seventh Framework Program for research, technological development and demonstration, grant agreement no FP7-KBBE-2013-7-613802).
From KNAUER’s perspective, the new IMPRESS program can thus be seen as an advancement of Valor Plus. “During the research project “Valor Plus”, KNAUER successfully developed an SMB process for the purification of Xylitol from a non-food plant-based feedstock fermentation. We are happy that we can now continue helping to implement industrial production of chemistries based on renewable resources.”, says Dr. Matthias Lübbert, Business Development Manager at KNAUER in Berlin.
There are several other processes involved in this research project, including biotechnology to break up the plant material into sugars. Using sustainable catalytic process technology, this can then be further turned into important base chemicals. Newly developed separation methods will be needed to purify intermediates and/or end products.
The IMPRESS consortium consists of ten leading European companies, science institutes and academic organisations: Avantium (NL, Coordinator), Sulzer (CH), KNAUER Wissenschaftliche Geräte (DE), IRCELYON (CNRS, Claude Bernard Lyon 1 university, FR), Lenntech (NL), Vogelbusch Biocommodities (AT), PDC Research Foundation (NL), Thinkstep (DE), Aalto University (FI) and South-Eastern Finland University of Applied Sciences (Xamk, FI).
The IMPRESS project has received funding under the SPIRE program under grant agreement No 869993. SPIRE, part of Horizon2020 which is the European subsidy program to facilitate a Sustainable Process Industry in Europe.
