This paper presents the results of Portuguese case studies on developing an industrial network around a construction site and three zero-waste demolition projects. The case studies analysed to what extent it is possible to achieve a significant reduction of the solid waste produced and an overall decrease in energy and water consumption. The results show that the reduction targets could be achieved by implementation of good practices in waste management and the development of networks to allow an increase in the reuse and recycling rates of wasted materials and residual water. At the construction site, overall achievement of reduction rates was additionally enforced by the substitution of inputs with strong potential impacts on the decrease of fresh water consumption and greenhouse gas emissions along the supply chain.
