The COMAR project is focused on the search of new ways to recycle and reuse waste coming from composites based on thermostable and vitrimeric matrices, through different chemical recycling techniques such as pyrolysis and solvolysis. With its participation in the COMAR project, Técnicas Reunidas S.A. (TR; Madrid, Spain) aims to develop the catalytic pyrolysis technology applied to the recycling of composite materials with two fundamental objectives: to improve operating conditions to reduce processing temperatures and energy consumption; and, to obtain higher-value-added liquid pyrolysis products for applications, such as as fuel or as precursors for high-interest chemicals such as phenol, styrene, or BTX, among others.
The project’s objective is to develop new products designed for the construction, wind energy, and transportation sectors, using materials obtained through the recycling of composite wastes, while employing conditions that allow for the preservation of the mechanical properties of the obtained fibers or their restoration if necessary. The byproducts obtained, for example, in processes like solvolysis, will lead to the formation of new matrices that can be used in these sectors or others of interest.
For liquid fraction valorization, COMAR will collaborate with Repsol S.A. (Madrid, Spain), acting as an external advisor, with the aim to tailor the composition and performance of these fractions to market needs. Técnicas Reunidas is carrying out this project in consortium with Mesbook, Rover Infraestructuras, InCom Group, Sofitec, Aerox, UBE and Azvi. The project has been granted with CDTI financing, coming from the Spanish Ministry of Science, Innovation and Universities, and co-financed by the European Regional Development Fund (ERDF), through the Pluri-regional program Spain ERDF 2021-2027.
