The project is based on the application of sewage sludge technology making it possible to include heat-dried sludge from wastewater treatment plants in cement mixtures used to manufacture prefabricated concrete. This technology was the result of a research project developed by the UPC with the support of the Catalan Water Agency and the companies ACYCSA and Taller de Ingenierías, S.A. The project focused on the development of a line of concrete slabs incorporating dried sludge as an additive to the cement used.
The project is an example of how a continuously generated waste that is difficult to manage can be recovered and transformed into a quality product with value (upcycling).
