Krysiński, Dawid (author)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...conference paper 2017

Alexanian, S. (author), Hubert, F. (author), Buyle-Bodin, F. (author), Blanpain, O. (author)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...conference paper 2017

Bougrain, Frédéric (author), Laurenceau, Sylvain (author)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...conference paper 2017

Tebbatt Adams, Katherine (author), Osmani, Mohamed (author), Thorpe, Tony (author), Hobbs, Gilli (author)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...conference paper 2017

Castro, Maria F. (author), Mateus, Ricardo (author), Bragança, Luís (author)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...conference paper 2017

Drewniok, Michał P. (author), Dunant, Cyrille F. (author), Allwood, Julian M. (author), Cullen, Jonathan M. (author)With growing pressure on the construction industry to be more resource efficient, to reduce waste and to lower embodied carbon, material reuse strategies are critical to meet targets, especially for steel. Indeed, steel recycling is an energy and carbon intensive process, offering only approximately 50% energy savings [1] and 75% [2, 3] over new...conference paper 2017

Hobbs, Gilli (author), Adams, Katherine (author)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...conference paper 2017

Augiseau, V. (author), Barles, S. (author)Flows of construction materials through urban areas are significant not only in terms of consumption but also of processed output. They raise environmental issues together with land-use conflicts. In Paris region in 2013, domestic material consumption reaches 2.5 t/inhab. while local and exported processed output amounts for 0.7 t/inhab. and...conference paper 2017

Braymand, Sandrine (author), Roux, Sébastien (author), Fares, Hanaa (author), Feugeas, Françoise (author)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...conference paper 2017

Wang, K. (author), Vanassche, S. (author), Ribeiro, A. (author), Peters, M. (author), Oseyran, J. (author)One of the expected key outcomes of the Horizon 2020 BAMB (Buildings As Material Banks) project is new business models for material circularity. The team has interviewed four “frontrunner” cases which have pioneered in incorporating elements of building circularity. The study included well-known cases such as the new Venlo city hall (the...conference paper 2017
