PULP2VALUE

Processing Underutilised Low value sugar beet Pulp into VALUE added products

Summary

Europe produces around 13 million tonnes of sugar beet pulp each year. Currently, most of this pulp finds its way into low value feed, bio-fertilizer or it is used for creating green fuel gas.

By using multiple extraction techniques, PULP2VALUE will extend the high value products extracted from sugar beet sidestreams, isolating microcellulose fibres (MCF), arabinose (Ara) and galacturonic acid (GalA).

The project will demonstrate an integrated and cost-effective cascading bio-refinery system to refine sugar beet pulp and identify applications for approximately 65% of its mass in high value markets, increasing its current value by as much as 20-50 times.

Description

Objectives: 
  • Demonstrate an integrated and cost-effective cascading biorefinery system to refine sugar beet pulp (SBP) that allows the conversion of 65% of its dry mass into high value products: microcellulose fibers (MCF), arabinose and galacturonic acid.
  • For each of these products, value chains will be developed, such as detergents, personal care, oil & gas, paints & coatings (from MCF), flavour and food products (from arabinose) or cosmetics (from galacturonic acid).
  • Create local cross-sectoral value chains involving the sugar, chemical and food industries.
Expected impacts: 
  • Demonstration of 9 new value chains for the processing sugar beet pulp into bioproducts with a market potential of 350.000 tons and 200 million Euro
  • Improved valorisation of side streams from production of sugar beet: current valorisation route of beet pulp is mainly towards animal feed and biogas, whereas PULP2VALUE will use 65% of the dry mass of SBP to high-value advanced applications.
  • Reduction of carbon footprint through the use of MCF and chemical building blocks instead fossil-based products such as glass or kevlar.
