Circular Economy

Our knowledge of transformation processes at the service of a more sustainable future

Maire Tecnimont’s approach to the Circular Economy has a precise goal. We apply our know-how in chemical engineering, of the hydrocarbon transformation processes, and of the production of polymers from fossil sources to a new paradigm for a more environmentally sustainable plastics consumption. We do this by developing bio-based materials and increasing post-consumer plastics recycling quality, and by the chemical conversion of waste plastic fractions that cannot be recycled.

The fundamental challenge regarding the sustainability of plastics is to adopt a more balanced use of them, and improve waste management. The fundamental answer to this problem lies in consumer education, on the one hand, and in the development of forms of recycling and recovery of waste on the other, which can be enhanced both by increasing the share of recycled polymers on the market and in the raw material mix of the supply chain. New technological solutions for recovery, including through chemical conversion, are crucial.

We are deeply committed to finding solutions to make plastics more sustainable throughout their entire life cycle, in order to contribute to a new circular and low-carbon economy. NextChem is also investing heavily in pyrolysis, a technology that allows plastic waste to be transformed into low-carbon fuels, which can then be further improved by making them into Sustainable Aviation Fuel.

NextChem is also involved in depolymerization and has assumed the role of coordinator of the DEMETO project, funded by the European Union. The project aims to provide a response to the ageold problem of recycling plastic materials and, more specifically, of polyethylene terephthalate (PET), a polymer belonging to the polyesters class of plastics. The goal of the DEMETO project is to develop the chemical recycling technologies for PET and polyester-based textile fibres; these solutions are based on the alkaline hydrolysis reaction and are assisted by the use of microwaves to significantly reduce reaction times.
