Promoting sustainable construction with our low-carbon solution
All the Group’s divisions are able to produce effective commercial solutions that avoid a significant amount of CO2 emissions compared with standard levels required by regulations, reduce residual emissions and develop alternatives that do not use fossil fuels.
We took a major step forward in 2018 by adopting a new indicator that measures the carbon emissions avoided through use of our greener solutions. Eiffage is the first group in the sector in France to have introduced this type of indicator and will thus encourage all its entities to push for the adoption of lowcarbon solutions.
Expanding use of biosourced materials
We are making greater use of biosourced materials, including recycled cotton, wood wool, natural linoleum, hemp concrete and clay. Similarly, Eiffage has already used timber, a 100% natural and recyclable material, in some 30 projects, including several residential complexes. In Bordeaux, we are building Hypérion, France’s tallest timber-framed structure.
Integrated engineering offices from the recently set up specialised subsidiary Eiffage Construction Bois are brought in from the design stage. In 2018, we also acquired a business that specialises in industrial roof frames. Likewise, we established a Company label to track timber “from the forest to the worksite” – the first of its kind in France.
Reducing or replacing raw materials that generate emissions
Optimising the energy efficiency of building materials and structures is another way for us to develop low-carbon construction. For example, we are trialling clinker-free concrete. The carbon footprint of our clay-based cement is just a quarter of that of traditional cement. We are also participating in research programmes that aim to recarbonate and recycle used concrete. The FastCarb project, for example, aims to facilitate the recycling of used concrete by injecting it with CO2.
Lastly, Eiffage Route has developed an insitu road resurfacing process reusing existing materials and employing alternative solutions based on warm, recycled or biosourced aggregates as part of its drive for more sustainable roads. Recytal-ARM®, a bioregeneration solution for aggregates using plantbased binders, can cut the carbon footprint of our aggregates by a factor of 10
of old bitumen road surfaces can be recycled using Recytal-ARM®
