Thermoplastic composites manufacturing could be a potential end-of-life option for separated construction and demolition waste. This study aims to find out how well the established ecodesign methodologies support the choice of recycled composite materials in new product design, and what challenges these materials offer to the designer. A product design case study was conducted by applying the ecodesign methodologies Environmental Quality Function Deployment and Technique for Order of Preference by Similarity to Ideal Solution, to identify the main promoting and demoting factors from the designer’s point of view. The rate of recycled material is the main promoting factor, but biodegradability, recyclability, and the mixing of materials are usually demoting the composite use. The use of multiple criteria analysis techniques can work in favor of the composite, as the mechanical and physical properties are taken into consideration. The paper discusses the potential challenges the designer faces when evaluating the feasibility of using recycled material composites. The design suggests that new uses for waste that previously went to landfill, such as mineral wool, can be found with composite solutions.

Abstract The construction sector plays a crucial role in the transition to a circular economy and a more sustainable society. With this objective in mind, Flanders – the Dutch speaking part of Belgium – makes use of a traceability procedure for construction and demolition waste in order to guarantee that value can be derived from downstream waste processing activities. This article takes this traceability procedure as a legal case study and examines if the use of blockchain technology could lead to even stronger supply chains, better data management, and, more generally, a smoother transition to circular practices in the construction sector.

Construction and Demolition Waste come from debris generated during construction, renovation and demolition of buildings, roads, and bridges. Recycling and reuse are essential in terms of sustainability, mainly from an environmental point of view. Although the recommendation of the use of these recycled aggregates is currently included in some technical specifications, its use is still not widespread due mainly to the lack of knowledge on their technical application. This work is a compilation of the recommendations proposed in the “Catalogue of road pavements with recycled aggregates”, supported by the construction of experimental stretches. It proposes different structural sections for road pavements by using recycled aggregates.

Demolition Waste

The demolition of buildings, apart from being energy intensive and disruptive, inevitably produces construction and demolition waste (C&Dw). Unfortunately, even today, the majority of this waste ends up underexploited and not considered as valuable resources to be re-circulated into a closed/open loop process under the umbrella of circular economy (CE). Considering the amount of virgin aggregates needed in civil engineering applications, C&Dw can act as sustainable catalyst towards the preservation of natural resources and the shift towards a CE. This study completes current research by presenting a life cycle inventory compilation and life cycle assessment case study of two buildings in France. The quantification of the end-of-life environmental impacts of the two buildings and subsequently the environmental impacts of recycled aggregates production from C&Dw was realized using the framework of life cycle assessment (LCA). The results indicate that the transport of waste, its treatment, and especially asbestos’ treatment are the most impactful phases. For example, in the case study of the first building, transport and treatment of waste reached 35% of the total impact for global warming. Careful, proactive, and strategic treatment, geolocation, and transport planning is recommended for the involved stakeholders and decision makers in order to ensure minimal sustainability implications during the implementation of CE approaches for C&Dw.
