The built environment is considered as a key sector in which circular economy can be implemented. Within the H2020 project “Building as Material Banks” (BAMB), two innovative solutions are being forward to support this transition: i.e. Materials Passports and Reversible Building Design Protocols. Based on desk research and interviews with...

Whilst there is an increasing recognition of the circular economy concept within the building sector, opportunities for its implementation at project level remain largely underexploited. Research has shown that challenges to its uptake include limited knowledge and awareness among stakeholders; a fragmented supply chain; an unclear business...

The waste management is a pregnant problematic in the European continent and in France too. The new paradigm called circular economy aims to be driver for the waste valorization. This objective is particularly applied in the civil engineering, the first generator of CDW (Construction and Demolition Waste) in France. In this context, except the...

In France the building industry accounts for the largest share of greenhouse gas emissions. It represents about one quarter of France’s national emissions. To deal with this challenge, the French energy transition for Green Growth law was adopted in July 2015. Buildings renovation, clean transport, renewable energy and the circular economy are...

To reach ambitious goals of Europe 2020 Strategy, circular economy concepts need to be widely adopted. In terms of construction sector, which generates almost 10% of European GDP but on the other hand consumes enormous quantities of raw materials, other materials and energy, the idea of circular economy can be achieved by strategic,...

The main goal of this paper is to identify barriers and opportunities for creating the circular business models in the EU C&DW sector. Having in mind this fact, author of the paper describes market, social, governance and regulatory failures which may limit opportunities for achieving market success in the EU C&DW sector. The presentation will...

Automated optic inspection of concrete aggregates for pollutants (e.g. wood, plastics, gypsum and brick) is required to establish the suitability for reuse in new concrete products. Inspection is more efficient when directly sampling the materials on the conveyor belt instead of feeding them in a sampled stream to the sensor system. However,...

Global demands on natural sand and gravel are growing beyond 50bn tonnes per year and there is a very real need to find alternative sources for construction. The basic processing of C&DW involves the introduction of dry processing equipment such as crushers and screens. This approach limits the use for the recycled sand and aggregates to low...

Abstract only - The existing construction waste recycling technologies and standards have been long applied in construction and demolition (C&D) waste recycling, mainly focused on the production and use of coarse recycled aggregates. Very few papers and process focus on the production of recycled sand although some previous results show that...

Production of waste materials, via industrial and human activities, creates big environmental and economic problems but also opportunities to recover valuable resources. EU28 currently generates 461 million tons per year of ever more complex Construction and Demolition Waste (CDW) with average recycling rates of around 46%. There is still a...

The framework of the research presented in the paper is a project oriented to promote the use of construction and demolition waste (CDW) as a new resource for constructing sustainable and very low-energy buildings. Intensive research activities have been carried out in application of recycled concrete and recycled brick as a replacement of...

BRE have been working with the reclamation sector in the UK for around 20 years to promote the reuse of end-of-life building products and materials in preference to recycling and recovery. Much of this has been dedicated to the promotion of pre-demolition and prerefurbishment audits to facilitate targets being set and markets for reusable...

The recycled concrete aggregates (RCA) produced by the demolition of old buildings seem to be an option in order to construct new buildings and to preserve the environment by the reusing of inert materials, reducing the resort to the natural materials and the disposal in landfills. Numerous countries are multiplying studies concerning this...

Sustainability concerns are in all sectors’ agendas, and building industry is not an exception. Sustainable design should both, reduce the environmental impact caused by buildings throughout their life cycle and positively contribute to people’s well-being by addressing and being adaptable to their needs. There is the need for an early design...

Construction and demolition waste stream has generated news materials that may be reintroduced into new concrete, e.g. as recycled aggregates. The specific feature of recycled concrete aggregates (RCA) is the presence of hardened mortars influencing their behaviour. This study aims to distinguish processes that allow the complete separation and...

The health sector has a strong influence on the economy of nations and their policies and is based in a group of buildings where the quality of the indoor and outdoor environment is quite important. The impacts of these buildings are relevant compared to other buildings because they are directly related to human health. The healthcare providers...

Nowadays, buildings consist in an assembly of several components and systems allowing them to fit the users’ technical, functional and comfort needs. In general, buildings’ systems and components are rather integrated into each-other and therefore, rather difficult to maintain, repair, update or dismantle separately, leading to precocious...

The presented BIM-SD tool is a software tool supporting the user in the pre-demolition audit and C&DW assessment. Its main objective is to support the collection and management of information on the existing elements and materials in a building to be demolished, the decision making around the optimal demolition sequence and the management of the...

Since the Industrial Revolution, humanity’s use of natural resources has been basically the same: TAKE, MAKE and THROW AWAY; which consequently led to the indispensable problems of waste materials. Around 461 million tons of Construction & Demolition Waste (C&DW), excluding excavation materials, are yearly generated in EU28. This undoubtedly...
