Abstract: 
Environmental protection is an essential human problem and that is why most countries in the world are taking measures to limit it. As we know, pollution is contamination with materials that damage health, quality of life, or the natural functioning of ecosystems. Although some environmental pollution is a result of the action of nature, most are caused by human activity. The disposal of waste from various industrial processes affects the quality of the environment. A particular current problem with environmental pollution is waste as a whole, including construction and demolition waste. Another current problem is noise pollution with negative effects on humans. In this paper, these two problems are addressed through the valorization of these types of waste and the production of composite materials with sound-absorbing properties. Six types of construction and demolition wastes are used and subjected to physical-chemical analysis to determine their moisture content, particle size, and chemical composition. Through an optimized technological process, composite materials were obtained and their sound absorption capacity was determined.
