Samenvatting

There is an increasing interest in paper-based packaging materials for (food) packaging because of the established paper recycling infrastructure and the negative public opinion about the environmental effects of plastic. Still, paper by itself cannot compete with plastics concerning (barrier) properties and the protection of packed foods. At present, commonly used barrier materials in paper laminates are PE (waterproofing) and aluminium (gas- and UV-barrier). However, their main drawback is that they negatively influence the paper recyclability. Moreover, whereas paper will degrade in nature, the polymer (e.g. PE) coating will persist resulting in micro-plastics.
In this project, alternative biodegradable or water-soluble barrier materials will be combined with paper surface modifications and thin coatings in order to obtain a material that can provide excellent water vapor and gas barrier properties. Furthermore, the provided solution would fit within the current paper recycling systems and be suitable for food contact applications. This project is a collaboration of Wageningen Food & Biobased Research, Unilever Research and Development, Jacobs Douwe Egberts and Royal Vaassen Flexible Packaging, part of Clondalkin Group. This development will help the participating companies to fulfill their circularity goals and help to prevent plastic pollution.

Doel van het project

The project’s deliverables – if successful – will open the food packaging market to recycled paper products, will provide packaging solutions that fit with circularity goals, will help to prevent littering and plastic pollution and will improve the quality of current recycled products. This would allow the consortium partners to extend their portfolio with a new packaging concept (Clondalkin Group), and contribute to achieving sustainability / recyclability targets (Unilever and JDE). As such, the project will strengthen the position of Dutch packaging producers, food industry and paper industry.

Relatie met missie (Motivatie)

The project aims to contribute to the following missions (M), priorities (P) and key technologies (KT) defined by the TKI: (1) Development of new biomass based processes and application for carbon storage in long-lived applications (M: climate neutral agriculture and food production, P: subtheme 5) and (2) Bio-based materials for packaging and sustainable food packaging (KT: advanced materials for mission driven innovation). Finally, this project strongly contributes to multiple societal challenges listed in the “Kennis- en Innovatieagenda 2018-2021”. CO2 reduction, circular economy, and bio-based materials are at the heart of the intended innovation.

Geplande acties

• Circular packaging concept including at least one up-scalable (industrially viable) coating/laminating material and technology (Q2-2021)
• Pilot trial at Royal Vaassen with enough material for pilot trials at UL and JDE (Q3/Q4-2021)
• Proof of recyclability (in the paper stream) of the developed material (Q2-2021)
