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...

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...

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...

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...

Luxembourg is witnessing a rapid development in the construction sector including renovation of the existing building stock and due to its small size, the country needs an efficient management of the resulting construction and demolition (C&D) waste. National legal obligations require contractors to carry out an inventory of building materials...

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...

In many developing countries, the rapid growth of town and cities has generated a rising levels of waste and illegal dumps have become a serious issue. The booming construction industry in Mongolia has resulted in the production of massive amounts of CDW which is one of the largest waste streams. In Ulaanbaatar (UB) and other cities in Mongolia,...

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...

According to estimates of the German Federal Ministry for the Environment, the German building stock contains around 10.5 billion tonnes of mineral building materials, around 220 million tonnes of timber products and around 100 million tonnes of metals. Due to continuous building activities, especially renovation and retrofit measures, it is...

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 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...

Abstract only. Associated with the continuing increase of construction activities such as infrastructure projects, commercial buildings, and housing programs, China has been experiencing a rapid increase of construction and demolition (C&D) waste. Till now, the generation and flows of China’s C&D waste has not been well understood. This paper...

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...

Abstract only. Today we are getting more and more confronted with the finiteness of mineral and fossil deposits of organic material. Extraction costs are rising and the availability of resources is decreasing. Together with an increased demand -as world population expands and developing nations are becoming wealthier- the situation will become...

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...

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...

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...

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...
