BEET2BIOREF

The object of Beet2Bioref will focus on the development of green processes for the production of biodegradable packaging as well as added value products (e.g. proteins, pectins) from sugar beet pulp, agricultural residues (beet leaves) and sugar / molasses surpluses resulting from the production of sugar beet.
The cultivation of sugar beet (land, farmers) and the EBZ’s facilities constitute a significant capital potentially exploitable under the concept of circular economy. Through the project, EBZ will be upgraded to a sustainable biorefinery through the valorization of by-products generated from sugar production opening new profitable business prospects.
The implementation of Beet2Bioref’s objectives includes the development of integrated process for the production of biodegradable packaging. Beet2Bioref will focus on optimizing the biotechnological production of poly (3-hydroxybutyrate) (PHB), the copolymer of 3-hydroxybutyric acid and 3-hydroxy valeric acid (PHBV), bacterial cellulose as well as pectins and proteins.
The aim is to find optimal sustainability indicators and to produce innovative biocompatible packaging materials that meet the optimum design requirements for fresh vegetable / bakery packaging and also the recycling requirement according to the European Strategy for plastic packaging. New materials that have inherent high permebilities to water vapours will allow the development of equilibrium modified atmosphere packaging (EMAP) solutions for specific vegetables and fruits offering a competitive edge over traditional oil-based plastic sheets. At the same time, biobased PHB / PHBV plastic sheets will allow better removal of water vapours in the packaging of hot bakery products. The use of by-products as raw materials, the improved processing and ingenious formulation of the bioplastic mixture will reduce the cost. This reduced cost combined with the improved functionality of the packaging will result in a successful commercial product. The alternative bio-based packaging materials will have improved moulding properties and functional properties and will be recyclable according to the design requirements for plastic packaging materials.
