The construction industry is one of the most polluting due to its high contribution to CO2 emissions. In addition to its significant environmental cost, its materials are made from nonrenewable resources such as sand and gravel, making the search for sustainable alternatives an urgent challenge in a context where growing production demand must be balanced with environmentally responsible practices. The sector is therefore investigating the development of low-carbon-footprint materials within a circular economy and decarbonization strategy, replacing traditional materials with the waste and surplus of other industries that, in turn, struggle to dispose of their by-products.
