As VolkerWessels, we want to reduce our environmental impact by using raw materials. We do this by gradually increasing the share of renewable and reused materials and by reducing the share of primary raw materials.
Our strategy for asphalt is aimed at increasing the share of recycled raw materials in asphalt mixtures. Our ambition is to have at least one variant in every mixture category that does not contain primary raw materials, is produced in an energy-neutral manner and is reusable to a high degree. An important challenge in this respect is that the quality of the asphalt must not be compromised. A great deal of research and experimentation is required to achieve this.
VolkerWessels uses concrete in the construction of buildings, bridges and tunnels, among other things. The production of cement puts pressure on the environment. We have the ambition to make building with concrete more sustainable. At the same time, clients, regulators and the cement industry play a major role in this. We are in discussion with the entire chain to make concrete more sustainable. In 2021, the BetonAkkoord is expected to set out the detailed plans, to which we are actively contributing.
Zero-energy bill homes
For the homes we develop ourselves, our target for 2025 is that 70% will be energy-less. That means residential units without a gas connection and with an energy bill of €0. This goes further than the current legislation for energy-neutral construction. We are aiming for this because a large proportion of all CO2 emissions occur during the usage phase of homes. Our MorgenWonen residential concept, of which we have built the 2000th home in 2020, is energy-neutral, for example. In 2020, more than 50% of all homes developed by VolkerWessels will be energy-free.
