Bricks Obtained from Industrial and Agricultural Waste

Waste management raises many environmental problems, and for this reason, researchers are looking for solutions for the subsequent recovery of waste in order to achieve the concept of circular economy. The purpose of the research carried out by the authors is represented by the use of waste, such as that from agriculture and from some industrial activities in order to obtain construction materials (bricks). Agricultural waste has become increasingly used in construction due to the improved characteristics of the material obtained, mainly in terms of thermal and acoustic insulation, lower costs, and environmental protection by reducing the use of conventional raw materials. The use in the composition of construction materials of plant waste, such as cereal straws, sunflower stems, represents a solution to reduce pollution similar as industrial wastes were used the industrial wastewater treatment sludge and fiber glass. The authors, as part of a research project, designed and tested new recipes for making bricks, starting from a series of existing waste materials in significant quantities.
