The main goal of DECOAT is to enable circular use of textiles and plastic parts with (multilayer) ‘coatings’, which are typically not recyclable yet. These ‘coatings’ comprise functional and performance coatings and paints as well as adhesion layers. Therefore, novel triggerable smart polymer material systems and the corresponding recycling processes will be developed. The triggerable solutions will be based on smart additives (like microcapsules or microwave triggered additives) for the ‘coating’ formulations that will be activated by a specific trigger (heat,humidity, microwave, chemical).
A continuous recycling pilot plant will demonstrate the novel DECOAT principle that allows upgrading existing
mechanical recycling by adding tools for sorting by and activation of the trigger. The optimal use of the Creasolv®
process for recycling of coated parts will be assessed. The focus is on recycling of the bulk material, but re-use of the
coatings materials themselves will also be tackled. Using these recycling processes, circular use of demo cases for
outdoor gear, household electronics and automotive parts will be validated.
To reach this ambitious goal and to maximise the impact of DECOAT project on the textile and plastics sector, eight concrete key objectives have been defined:
1. Development of a toolbox of triggerable materials for debonding on demand suitable for use on textiles and plastics.
2. Development and design of triggerable debonding coating solutions for ‘disassembly’ of parts or objects and for ‘removal’ of the coating from the multilayer structure. Focus is on acrylates, polyurethanes and PVC materials.
3. Automation of sorting according to the required trigger.
4. Integration of debonding systems in a continuous pilot plant recycling line for coated parts.
5. Demonstration via use cases (outdoor gear, household electronics and automotive parts) using the pilot recycling
plant and the adapted coating processes during manufacturing.
6. Assessment of environmental impact and implementation of safety-by-design (safe product, safe production and safe use and recycling).
7. Exploitation and business plans for the DECOAT results, including for the use cases manufacturing guidelines to
ensure implementation at industrial scale. Further, for the more generic results (design-material concepts) a thorough analysis will be done for wide scope exploitation within the textile and plastics sectors.
8. Dissemination and communication among relevant European communities. The main target is the European materials and recycling community, supplemented by the wider stakeholders group, both for getting extra feedback during project implementation and for promoting our results.
