Forced by environmental implications and by legislation requirements, the cement sector is moving towards more circular economy practices, with the primary aim to enhance the sector sustainability. This commitment translates into product technology innovation, but also into innovative development perspectives for the industries involved in the supply chain. Moreover, dealing with recycled materials can modify the interaction among stakeholders from a conventional supply chain to an industrial symbiosis approach, where companies mutually exchange products and by-products into circular interactions. The purpose of this article is to investigate the circularity performances deriving from the production of a cement mortar reinforced with recycled synthetic fibers coming from artificial turf carpets. From the collection of artificial turf carpets at the end-of-life stage it is possible to recover several materials: plastic fibers used in the cement mortar, and in addition, silica sand, rubber, and bituminous membrane. The production of the innovative reinforced cement mortar leads to the connection between industries belonging to different sectors and consequently to uneven economic and environmental implications. Starting from the available literature, this study aims at evaluating the circularity potential of the unusual interactions among companies to support the development of an effective strategy, reducing environmental and economic pressures. |
