This book offers a valuable tool for understanding current efforts to promote the reuse and enhancement of pre-consumer waste in the development of new products for the construction sector, as well as the financial and regulatory tools being used to support this trend. It explores the vast and complex topic of the circular economy from the perspective of strategies for the reuse/recycling of waste, and develops a number of key premises: waste reuse/recycling must be considered using a logic of cross-sectoriality, recognizing the need to enhance the "dialogue" between different sectors; pre-consumer waste is particularly interesting for the recycling market because the construction sector can reduce its environmental impacts by enhancing its capacity to use secondary raw materials and by-products from other sectors; and lastly, the manufacturing sector is currently experimenting with promising forms of reducing/recycling pre-consumer waste and is at the same time providing by-products that can be used in other production chains. As such, the book offers a valuable asset for professionals who are interested in sustainability in construction, and in the study of construction products; however, it will be equally useful for local decision-makers tasked with implementing development policies and innovations in the industrial sector.
