Koolhydraat gebaseerde schuimen als duurzame Vervanger voor Expanded Polystyreen
Worldwide governments and the general public have become aware of the need to replace plastic packaging by more sustainable products. For tableware this has already resulted in legal bans. For light weight packaging products a real shift to paper based materials is taking place. In the market of heavier electronic devices, housekeeping appliances or packaging of e.g. garden furniture, there is the need for a light thick bio-based material with an acceptable price that can replace commonly used oil based plastic foams and that could be recycled with paper.
In this project, PaperFoam bv, Paxpring bv en Bewi Synbra Group collaborate with Wageningen Food & Biobased Research to develop (a new technology for the production of) thick-walled starch based packaging materials. This new packaging material will be a green alternative for current oil based materials used for heavy products.
The project aims to contribute to the following missions (M) and key technologies (KT) defined by the TKI: Bio-based materials for packaging (KT: advanced materials for mission driven innovation). 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.
For heavier products there is not yet an alternative packaging solution, which has lower CO2 emissions, consumes less oil based products and has the potential to fit within the circular economy (recyclable with paper). The thick walled packaging material from this project can help in this transition.
In this project, the partners aim to develop (a new technology for the production of) thick-walled starch based packaging materials suitable for heavy products. This new material will be a green alternative for current oil based materials. The deliverables include:
1) Confidential report comparing different technologies (Q1-2021)
2) Three pilot tests of the chosen route (extrusion), first in March 2020 and the two following in June and October 2020, this last one delivering a product prototype. For the two last ones a project extension was asked.
3) (When possible) a scientific publication on rheological properties of starch based materials (data generated for preparation to the pilot test) – End of the project
