Objective: AGGREGACO2 project targets the aggregates industry for a revolution through the successful commercial deployment of a sustainable aggregate as a solid alternative of conventional aggregates not fully environment-friendly. The AGGREGACO2 proposes a FOAK innovation through the introduction of CO2 captured of refinery processes in an Accelerated Carbonation Technology (ACT), that revalorise Air Pollution Control residues (APCr), which are hazardous residue nowadays stored after treatment, for the fabrication of carbon negative aggregates. The AGGREGACO2 project will demonstrate the industrial feasibility and cost-effectiveness of the first carbon negative aggregate that can compete face-to-face in the market while reduce drastically the GHG emissions emitted by refineries, the carbon footprint of the fuels and APCr in landfills. PETRONOR and OCO together with the Repsol Group, will become the first companies in the world in introducing industrial ACT processes perfectly connected with refinery plants, paving the way towards the transformation of the traditional oil & gas plants in places where fabricate derivative sustainable products with high added- value. This joint research produced attractive and promising results at high TRL-levels that make the AGGREGACO2 industrial concept profitable at mass fabrication level. A ?perfect symbiosis? scenario is achievable because the ACT process can be 100% fuelled using the CO2 captured in a refinery as resource. Therefore, the main objective of the project is to design, implement and validate the first commercial production plant of carbon negative aggregates (in EU) with a capacity of 56,000 Tn/years, with adequate stability (>7,000 h) and capable to revalorise 22,000 Tn APCr/year and use 2,200 Tn CO2 captured. This project will avoid 2,836.44 TonCO2eq/year (i.e. 28,364 TonCO2eq considering 10 years of project operation) and, besides that, REPSOL will produce around 400 Ton/year of low carbon hydrogen.
