Creating “green” composites with innovative resins
Composites are two or more materials with different physical or chemical properties combined in a way that they add more strength, efficiency or durability to the final material.
Composites are used everywhere – from aviation to energy infrastructure because they are lightweight, resistant, durable and do not require high maintenance. However, they are also difficult to recycle because the thermoset resins, a key component in composites can’t be melted down or transformed.
To solve this problem Arkema developed a thermoplastic liquid resin, which makes it easier to recycle composites. The recycling of composites made with this resin allows to easily recover the original raw material (monomer) that can immediately be used to produce new composites.
This innovation provides manufacturers with a sustainable recyclable alternative to conventional composites.

Circular Economy 2.0
In 2015, the European Commission published its Circular Economy package to promote the transition from a linear economy into a circular economy, where resource efficiency is increased and the value of products and materials is maintained for as long as possible. When a product reaches the end of its life, options such re-use, remanufacturing and recycling can be explored to create additional value. Circular Economy can bring forth economic benefits, by contributing to growth and job creation and stimulating innovation, and in parallel provide environmental benefits.
