Context

The last decade has experienced a strong increase in technological developments for improved material functionality. One of these involves surface treatments, which employ complex (multilayer) structures designed to provide multifunctionality in a single solution. This definition includes functional and performance coatings on textiles, paints on plastics, foil lamination and adhesion layers for plastics parts (polymer-polymer and polymer-metal connections). These ‘coatings’ have a wide range of advantages and benefits but currently cannot be recycled because of their hybrid nature.

Aims

The main goal of DECOAT is to enable the circular use of coated parts by developing novel smart polymer material systems, and their corresponding recycling processes.

We will demonstrate the project results by means of concrete use-cases for outdoor gear, household electronics and automotive parts.

DECOAT will implement a solution for a specific class of hard to recycle items: textiles and plastics parts with (multilayer) ‘coatings’. For plastics, these can be found in automotive, construction and electronics consumer goods. For textiles, typical uses are for technical textiles (outdoor gear, protective clothing, automotive applications and construction) and interior textiles (e.g. upholstery, mattress covers or curtains).

The coating can be added for performance or aesthetics reasons. Coating, paints or adhesives have to possess excellent adhesion because of the durability of the coated product, and as such cannot easily be removed. Consequently, full objects are discarded, even though the coating often only comprises some % of the total weight.

With DECOAT we will reduce the amount of waste material to the specific adhesive. This holds for end-of-life products but it is also one of the types of production scraps that are not efficiently recycled yet. Within this larger topic of debonding an emerging specific challenge is how to deal with scrap and end-of-life parts containing integrated electronics (from smart textiles, smart plastics and wearables).
