CIRTEC - Círculo Tecnológico

Cirtec, Círculo Tecnológico, is born from the union of two large firms, Valoriza Medioambiente and Composan Industrial y Tecnología. The purpose of this partnership is to create a company that is capable of bringing about a real circular economy in road work projects, with a commitment to project sustainability and environmental protection.

The main objective of CIRTEC is to offer public administrations, construction companies, producers of mixtures, engineering firms, planners, etc. technological products and solutions for the road in order to be able to make a reality of the concept of circular economy, providing technical solutions for asphalt mixes based on the use of products (rubber powder) obtained from the reuse of end-of-life tyres (ELT) and other waste-derived by-products.

At CIRTEC we have the best human, technical and material resources, allowing us to carry out – with our customers – not only the manufacture and supply of any type of bitumen rubber and the revolutionary RARx additives, but also to give technical advice within the confines of the highest standards with regard to the performance of tests, working arrangements, dosages, commissioning, quality control, etc.,  in order to ensure the correct execution and design of this type of asphalt mixes with rubber.

CIRTEC is a company that has joined the “Circular Economy Pact”

Cirtec is one of the companies joining the “Circular Economy Pact” led by the Spanish government within the framework of the “Europe 2020 Strategy for Growth” of the European Commission, whose objective is to turn Europe into a more efficient society when it comes to the use of resources.

This involves replacing a linear economy, based on extraction, production, consumption and waste, for a circular economy in which the materials contained in waste are reintroduced into the production process in order for them to be used for the production of new products or raw materials. At Cirtec, we make use of rubber powder from end-of-life tyres in order to produce extremely high performance asphalt mixes which are economically sustainable, thus helping to reduce the waste generated in our society (tyres), and creating new high-quality products through our activity and RDI projects.
