An intelligent additive that helps to recycle spray-on parts

- May 11, 2019-

In order to meet the 50 per cent recycling targets set by the European plastics industry, consideration must be given to intelligent solutions for recycling textiles and plastic components containing multiple layers of coating.Devan Chemicals, which supplies finishing Chemicals to the textile industry, has joined Decoat, a coalition that plans to tackle recycling of coated and painted textile and plastic materials led by Centexbel, a Belgian research and development centre.

The objective of Decoat is to get rid of paint and coatings on plastic parts and textiles and make them recyclable

The alliance plans to study smart polymer material systems that can be triggered and appropriate recycling processes.These solutions will be based on smart additives, such as microcapsules and microwave trigger additives, which allow the coating and other finishes to be effectively removed by specific triggers, such as heat, humidity, microwaves or chemicals, allowing for recycling.

Devan's particular role is to develop microcapsules that release their active cores at the end of the product life cycle using specific triggers such as heat.For example, this active core material may facilitate the separation of different coatings (by differentiating them), opening up the possibility of the underlying material being recycled/reused.Different active core components will be evaluated and Devan will develop the process.

The four-year project aims to reduce the amount of currently hard-to-recycle coated products, such as clothing, electronics and auto parts, by 75 percent.And reduce their carbon footprint by at least 30 percent.By recycling these materials, Decoat is on track to create a new market in Europe worth more than 150m ($170m) in the medium term.

The eu-funded project was launched on 20 February 2019 at the solstice 21 meeting of the European commission in Brussels, Belgium.The project alliance from the value chain of each link of the 17 European partners, members involved in the design, manufacture, non-governmental organisations (ngos), research and innovation unit, including plastic technology research Institute (Aimplas) in Spain, Germany's Fraunhofer Institute (Fraunhofer Institute), Spanish Maier (a decoration auto parts supplier), and panasonic Turkey branch.
