Abstract
The increasing population has been generating an increase in the demand for construction to meet the needs of shelter, work, and recreation, this situation has increased the consumption of construction materials. Global warming makes it necessary for the process of manufacturing traditional materials to be more efficient and environmentally sustainable. ??Nowadays concrete is the most produced and used construction material in the world and one of its components is cement. In recent years, cement production has reached more than 4 billion tons, however, it is a process that requires large quantities of non-renewable raw material, with a high energy consumption and potentially contaminating, being responsible for the production and the placement of 6% of CO₂ emitted into the atmosphere each year, which translates into serious environmental consequences.
??On the other hand, the generation of organic waste (biomass) has become a problem for the states, since the dumping of these wastes, due to their low recycling rate is causing serious concerns due to the associated contamination of the soil and the water, the large tracts of land necessary for its disposal, the emission of methane and other greenhouse gases during the degradation process, in addition to the management costs
