Summary

Although bioplastics offer numerous environmental benefits, they currently represent just 1.5% of global plastic production. Achieving a much larger bioplastics production requires significant investment and innovation throughout the plastics value chain. In particular, in the sector needs to work on recycling, biodegradability and performance aspects of bioplastics.

The POLYMEER project seeks to revolutionise bioplastics by developing new bio-based polymers, copolymers, and polymer blends based on brewers' spent grain (BSG), a major brewing by-product that poses disposal challenges due to its abundance and perishability. It constitutes 85% of brewery waste, with every 100 litres of beer yielding almost 20 kilograms of wet BSG. About 40 million tonnes of BSG are produced annually worldwide, with Europe accounting for approximately 8 million tonnes.

Recognising this untapped resource, POLYMEER envisions a transformative journey: harnessing BSG's potential to create bespoke bioplastics tailored for applications where existing bioplastics falter or conventional plastics still hold sway, namely in the agriculture sector (mulch films), packaging, and textile for the automotive industry. POLYMEER's innovative formulations promise to revolutionise industries while championing sustainability, prioritising eco-friendly processes, minimising environmental impact, and ensuring intrinsic recyclability or biodegradability. 

The POLYMEER project aims to minimise waste through innovative processes, thereby expanding the range of materials that can replace traditional plastics, by:

  • Optimising a safe-and-sustainable-by-design and reliable sequential process to fractionate wet BSG into fractions that serve as precursors for the synthesis of bio-based building blocks.
  • Developing an initial portfolio of at least 20 circular-by-design bio-based building blocks that are suitable for the synthesis of polymers, copolymers, and the formulation of polymer blends.  
  • Developing bio-based polymers and co-polymers with improved and unique properties, such as new thermoplastic polyesters and copolymers from bio-based lactone monomers, which can prioritise features like fertiliser ability, biodegradation, recyclability, or flame-retardancy.  
  • Formulating, producing, and testing at least four bio-based material candidates to meet the requirements in terms of thermal, mechanical, and functional properties at lab scale of the selected applications: plastic films for agricultural use; tertiary packaging for brewery; and textiles for automotive applications.
  • Considering in the recycling process the biodegradability potential from the initial step of the design phase and integrating it towards the full process.
  • Piloting the upscaling of the whole production process for the three different applications, from the BSG isolation stage to final product prototypes.
  • Optimising and demonstrating the life cycle sustainability and circularity of the new bio-based polymers, co-polymers, and blends developed in the project.
  • Assessing the cost-effectiveness, social acceptance, and techno-economic feasibility of the project.
  • Engaging with essential audiences and stakeholders as well as seeking input from policymakers and market participants in the relevant value chains to conduct a comprehensive market analysis. 

  • Furthering innovation and advancement to develop new bio-based polymers with tailored properties and functionalities, contributing to the availability of a broader range of bio-based products that meet market requirements.
  • Unlocking new applications not currently covered by bio-based polymers, within different sectors, including agriculture as well as the beer and automotive industries.
  • Improving sustainability, safety, and circularity when compared to fossil-based (or bio-based) state-of-the-art benchmarks.
  • Enhancing economic sustainability by reducing reliance on finite fossil resources, lowering production costs, and creating new markets.
  • Demonstrating evidence of promising product and process performance for reference applications in view of subsequent upscaling.
  • Significantly improving environmental performance across the value chain, against specified fossil and/or bio-based benchmarks (carbon footprint reduced by ≥30% compared to fossil-based counterparts).
  • Improving circularity and resource efficiency via practical application of the circular (bio)economy concept.
  • Enhancing competitiveness, attracting investments, and contributing to job creation in industries that adopt bio-based technologies.
  • Raising public awareness and eco-conscious consumer choices.
