Abstract: Numerous investigations were carried out incorporating various agro-industrial wastes into clay mixtures, in order to produce lightweight ceramic materials. In this work, some of these studies have been analyzed, taking as a starting point those that were developed under the same experimental conditions, in such a way that the variables to be analyzed are the densities of the biomasses, and the percentage of added waste. The selected biomass waste is peanut shells, pistachio shells, olive pits, corn cobs, among others. The characterization of these materials was carried out with various techniques. The XRD diagrams present in all cases the characteristic peaks of the crystalline portion of cellulose. The thermal behavior studies show exothermic peaks corresponding to the combustion-decomposition processes of the biopolymers present. The properties and characteristics of the ceramic products obtained have been studied, and it can be observed that, in all cases, for contents of up to 10% of residual material, the market requirements for this type of bricks are met. Furthermore, a detailed analysis of the shape and size of the pores produced in the samples has led to establishing an important relationship with the characteristics of the aggregated biomass particles.
