It is well known that the construction sector has harmful consequences for the environment, contributing to climate change, air and water pollution, and waste dumping. To change this trend, it is necessary to find new alternatives that replace conventional building materials in innovative and more sustainable ways.
Eutopia – the AI platform to access information about thousands of green startups in Europe – is once again excited to share with the readers of talenteco a selection of some of the most promising green startups developing construction materials.
