The BioBoard EU-funded project campaigns for the valorisation of discarded food and protein-rich waste in a bid to replace plastic coating for paper and board.
The BioBoard project, which promotes the material recyclability or compostability of coated paper and cardboard and derived laminates, will develop a new sustainable BioBoard barrier coating system.
The coating will be easily biodegradable and, where it is applied with enzymatic detergents, it will be easily washed off from the substrate.
Owing to increasing political, legislative and consumer pressure to minimise fossil fuel-based plastics dependency, and to produce recyclable solutions, the project is developing the coating system based on the renewable raw material derived from agrofood waste.
For the coating the base material will be new formulations based on proteins such as whey and residues from potato.
BioBoard, which will provide a solution to raise recycling rates of paperboard and cartonboard, will substitute the currently used PE by the new bio-based coating.
BioBoard project coordinator Dr Elodie Bugnicourt said the project is a response to demand from producers of coated paper, paperboard and cardboard manufacturers for a bioplastic that will enable them to substitute currently used synthetic coatings.
"BioBoard is based on a holistic integrated environmental approach to increase the sustainability of materials and processes throughout their lifecycle," Bugnicourt said.
The three-year project promotes recyclable materials for use in the food sector, closing the loop by applying their waste in novel packaging solutions.
The project, which received funding from the European Community’s Seventh Framework Programme managed by REA Research Executive Agency, consists of 14 partners from ten European countries.
