Research, Development, and Technological Innovation

Management of Construction and Demolition Waste (CDW): in March 2026, the Directorate of Environmental Administration of the Basque Government authorized CYCASA to carry out, on a professional basis, waste collection and treatment operations, under authorization code and registration number in the Waste Production and Management Register 16E02/001/26. These wastes, identified by their European Waste Catalogue (EWC) codes, are as follows:
 

This authorization is in addition to that granted in February 2024, when the Territorial Committee for Planning and the Environment of the Regional Government of Castile and León authorized the scaling-up of activities at the Santa M.ª del Cubillo plant for CDW management, with Environmental Identification Number 050000769 and authorization number for the installations for the management of non-hazardous waste 07G424050000769, allowing for the treatment of 21,000 Tn/year of European Waste List (EWL) Code 170503, with treatment code R0507 for the milling waste, and another 27,000 Tn/year of EWL codes 170101 (concrete), 170504 (earths and stone), and 170508 (railway ballast), with treatment codes R0506, R1203 and R1301.

Said management will allow reducing environmental impacts, increase reserves and the use of natural aggregates by means of adding CDW to the bituminous mixes and granular layers, and integrating the operation within a circular economy model of the EU’s Goals for 2030.

HAZITEK ECO2D4.0 project: “Experimental dimensioning of road infrastructures using strategic waste, and development of a monitoring and simulation ecosystem for the selection of sustainable solutions”. Currently in the data acquisition phase of the pilot test, it has been under development since 2022, it is devoted to the research and development of products for eco-friendly roads, and studies the technical and market feasibility of using different types of waste as secondary aggregates for road surfaces.
The members that make up the group are Befesa (which provides ferrosite as waste), FCC (with bottom ash from the MSW incineration), Tubos Reunidos (with black steel mill slag), Fuchosa (with green smelting sands) and CYCASA (with milling waste).

Quality, OHS and Environment: Integrated Management System certified by AENOR as per UNE-EN-ISO 9001, UNE-EN-ISO 45001 and UNE-EN-ISO-14001 standards. Civil and Railway Works, Railway and Road Service and Maintenance Contracts.
Certificate of Compliance of Factory Production Control, by CEMOSA, of the aggregates used for concrete, bituminous mixes, granular layers, and ballast.
Approved as aggregates supplier for ADIF’s AVE. ADIF’s quality label of aggregates for ballast: Type 1 (>=200Km/h).

Equality Plan: registered before Spain’s labour department on the 28th of March, 2023, with no. 012560.

Calculation of Carbon Footprint: on 17 November 2025, the certificate of registration in the Carbon Footprint, Offset and CO₂ Absorption Projects Register of MITERD was obtained, for scopes 1 + 2.
