A sustainable future with sustainable plastics

Plastic waste is one of the major threats to our ecosystems and the current end-of-life given to plastics negatively affects the environment. It must be highlighted that although packaging has been given a lot of publicity as a hook to make society aware of the problem and engage them into the Circular Economy concept, it is not the only plastic waste that ends up in the sea and on land. However, circular economy needs an optimal waste management to create an effective after-use plastic economy as a main strategy to promote recycling rates of plastics to avoid further plastic littering on land & sea and to reduce plastic waste diverted to landfill or incineration.
The use of composite materials and other hybrid structures have gained interest in recent years due to their unique properties such as high mechanical strength, good chemical resistance, long durability … which make them very attractive for a large number of applications in many high technological sectors, such as aeronautics, automotive, construction, marine, energy, sports, electronics, packaging, etc. These are formed by the combination of at least two constituent materials in which usually a polymer is used as matrix (either thermoset or thermoplastic). However, they still have many technical limitations such as their end-of-life due to their inherent complexity and the difficulty in applying an eco-design, generating plastic waste. This Session aims at shed light by showing recent solutions that tackle the problem all along the value chain, with a particular emphasis in novel technologies to dismantle (large composite parts) and separate (multi-layer/multi-materials) clean flows of high added value plastics and other materials for their reuse, remanufacture and recycling (where mechanical, thermal and chemical recycling is applied). However, other breakthrough technologies are arising that mimics nature such as the enzymatic degradation, in which experts from the session are working to provide ad-hoc enzymes for the controlled degradation of thermoset and thermoplastic plastics.
To make more sustainable (new feedstocks for biobased chemical components) and more efficient these end-of-life technologies, new chemical structure designs (such as tailored bonding/debonding interphase moieties) are also evaluated, what is opening a novel eco-design paradigm.
