Udvikling af klimaforbedret højstyrkebeton til vindmøllefundamenter baseret på biokul fra pyrolyse

Pyrolysis technology is currently being developed and scaled in order to contribute to a significant part of the energy supply of the future. This is based on residues from different branches of society — primarily fractions that today are categorized as more or less useful waste. Be it agricultural residues, just as it can be sludge from households. While the pyrolysis technology itself is not expected to be significantly different from species to species, the yield fraction biochar will have to be handled separately. If pyrolysis is to achieve the goal of also being used for more problematic substances — such as sludge or industrial waste that may contain harmful substances — such as PFAS — biochar from this cannot be used unhindered for soil improvement on agricultural land. Here, there is a need to develop alternative applications that ensure that harmful substances are bound.

At Y-MatTec, we specialize in developing concrete mixtures for wind turbine foundations. The ambition of the project is to develop a concrete product that utilizes the carbon from the reinforcing effect of pyrolysis, in order to create even stronger foundations for the wind farms of the future. In this way, the project will support both the value chain around pyrolysis technology and a very specific area within the wind turbine sector.
