Biorefinery
Demo Plant

World-leading research and development project

Advanced research and development work

In 2004, what was then called the Ethanol Pilot in the Domsjö factory area in Örnsköldsvik was inaugurated.

Here, Sekab E-Technology has carried out advanced research and development work to verify all the process steps required to commercialise the biorefinery technology that utilises the value of residual products from forestry and agriculture. The goal: chemicals and propellants that neither require fossil resources nor arable land, and which live up to the demands of the future with respect to environmental benefit and sustainability.

Around a hundred different research and development projects on cellulosic ethanol are being conducted globally, and Sekabs CelluAPP technology is considered to be among the foremost in the world, especially when it comes to wood as the raw material. The demo plant has been financed with money from the Swedish Energy Agency, the EU and Sekab and is owned by holding companies at the universities of Umeå and Luleå together with Sekab. Today the Demo Plant is operated in campaigns focusing on customer- and research projects.

The operations are financed through a combination of private and public funding.

What is unique in comparison with other development facilities is that it has been running continuously through shift work since 2004. The operational disturbances in the form of coatings, blockages, material wear and such like that arise in the process of prolonged operation are, together with the integration of a bioenergy combination, of crucial importance to the operating economy of a full-scale production plant. Sekab/SP has experience from about 50,000 hours of operation in the demo facility, which has created unique know-how and knowledge that as yet cannot be found anywhere else in the industry.

This is how we make sugar and ethanol from cellulose

The process developed by Sekab E-Technology consists mainly of four steps: pre-treatment, enzymatic hydrolysis, fermentation and reprocessing.
