Integration of efficient downstreaM PRocessEs for Sugars and Sugar alcohols


Avantium is coordinating a 4-year research programme entitled IMPRESS to accelerates its Dawn and Ray Technologies in addition to utilizing its expertise in Catalysis. The programme started in September 2019 and will last until 2023. IMPRESS is funded by the European subsidy programme to facilitate the region’s Sustainable Process Industry, SPIRE, part of Horizon2020.

Avantium’s Dawn Technology™ converts non-food plant-based feedstock into industrial sugars and lignin. The Ray Technology™ converts these industrial sugars into plant-based MEG and MPG. Together, these processes enable the production of nature derived products and supports the transition of the chemicals and materials industries to non-fossil resources. The integration of Dawn Technology™ with the production of plant-based MEG by the Ray Technology™ will be further improved by using the advanced high throughput R&D systems of Avantium Catalysis.


The objective of IMPRESS is to create a value chain starting from non-edible biomass to renewable chemicals and materials that meets both economic and sustainability criteria.

A main objective is to develop and upscale separation, purification and analytical test methods for upstream- (Dawn) and downstream (e.g. for the production of ultra-pure MEG and MPG, xylitol, fodder yeast, activated carbon and lignin nanoparticles) processes and integrate them to the IMPRESS demonstration scale process

It’s expected that the new purification and separation methods, and new high value products combined with benefits deriving from the integration will decrease OPEX and CAPEX

The environmental and techno-economic performance of the IMPRESS concept will be assessed by means of a Life Cycle Assessment (LCA) and a Conceptual Process Design (CPD), respectively.


This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 869993.
