The current overconsumption of natural raw materials is untenable. Raw materials already extracted should be valued by recovery to the highest possible level. The construction sector is the sector consuming the most natural raw materials and a paradigm shift is absolutely necessary. However, the production of construction materials is highly experience-based, which cannot be the foundation for such a shift. The sector must be transformed from founded on experience to founded on evidence-based research. In my research team, Waste2Materials, we build the foundation in science for the paradigm shift and develop new solutions based on this foundation. We focus our efforts on the huge masses of different particulate waste produced and acknowledge the necessity for separation to transform it into raw materials. The characteristics of the new raw materials and the well-known natural raw materials differ significantly. Simultaneously, we build the chemical and physical foundation for their use in construction materials and utilize this base to optimize the properties of the construction materials.
