The construction industry is one of those that most change the environment because it requires a large consumption of natural resources and produces large volumes of waste. Even though most of the construction materials that are wasted are considered waste, in reality, they are residual and for many their final destination is to go to landfills, but some have great potential to be recycled and reused and in this way reincorporate them into the construction. Waste management is a culture that must be implemented with the participation of all. The results of reusing block residues to convert them into aggregates and reincorporating them into the production process in the elaboration of blocks are presented. The social, economic and environmental benefits of having recycled aggregates are presented to strengthen the local program for the sale of construction materials.
