BATTLE CO2 project replaces 95% of fossil fuels in asphalt by biomass

20 march 2018

The researchers of this project have designed a new asphalt plant, in which more than 95% of the fuels used in manufacturing process have been replaced by biomass from sustainable forest management.

Road surfacing with asphalt mixes requires the use of a heat source that reduces the viscosity of bitumen so that the assembly formed by aggregates and bituminous binder has adequate workability.

Traditionally manufacturing plants use heat sources coming from non-renewable energy sources (fuel and gas) which significantly increases the environmental impact of paving process.

The Battle CO2 project seeks to integrate the manufacturing process by making use of biomass as a heat source and integrating the manufacturing process and job sites with the proximity to the points of supply of renewable energy, such as biomass.

The prototype plant developed by the members of the consortium is ready to start with the first set-up test. This first phase will allow the validation of the process through the realization of a test section that will incorporate asphalt mixture manufactured with this new operation model and that will serve to verify the environmental benefits of the new process, without prejudice to the mechanical properties of the products generated.

The results of the project will reduce the carbon footprint of asphalt mixtures (from the stage of extraction of raw materials until the asphalt mixture is located on the road) around 50%.  

The consortium, coordinated by CARTIF in Valladolid, counts on the participation of construction company COLLOSA, in whose facilities of Cubillas de Santa Marta (Valladolid), is where the implementation of the prototypes has been carried out in order to validate this new model of operation, and the support of the PTC (Plataforma Tecnológica de la Carretera)

With the follow-up visit by representatives of the LIFE unit of the European Commission and the external monitoring team of NEEMO-IDOM, scheduled for this month of March, the project faces the final stage of its actions aimed at improving the sustainability of the asphalt mix manufacturing process.
