The high volume of construction and demolition waste CDW generated today constitutes a serious problem CDW in the United States is estimated at around 140 million metric tons Yuan et al 2012 Eurostat estimates the total for Europe to be 970 million tons/year representing an average value of almost ton/per capita Sonigo et al 2010 It should be
Construction and demolition waste is generated in large amounts in medium and large sized cities in Brazil According to Schneider [1] in the year 2003 about 16 000 tons of solid wastes from civil construction were produced daily in São Paulo the largest Brazilian city representing 50% of the overall solid waste Furthermore only about one third of this material
1 Introduction Construction and Demolition Wastes CDWs typically comprise inert mineral materials concrete bricks tiles and ceramics etc with smaller amounts of other components wood glass plasterboard bituminous mixtures and tar [1] CDWs are one of the main sources of waste in Europe according to official data released by the European
The overwhelming amount of construction and demolition waste CDW brought by the ever accelerating rate of infrastructure construction renovation and maintenance has become a prominent issue from environmental standpoints Over the process of urbanization a dual dilemma has been revealed namely the short supply of non renewable resources
Construction and demolition C&D waste comes from engineering activities In Brazil thousands of tonnes of C&D waste are generated daily and they are often clandestinely disposed of in vacant lots riverbanks and outskirts of cities Most of the C&D waste generated in Brazilian cities could be fully recycled
Wood waste is by far the largest portion of the waste stream generated from construction and demolition activities Treated Wood Waste Wood treated with chemicals for preservation against insects microbes etc may need to be managed using alternative methods CalRecycle has an LEA guidance on treated wood waste handling Processing

Construction and demolition waste CDW end of life disposal methods such as landfill and incineration have contributed less than % to global GHG atmospheric emissions since 2010 on Climate Change IPCC However this is expected to grow significantly because of continuing industrialization and urbanization; for example CDW accounts for around 46% of
C&D waste refers to the waste generated during construction decoration and demolition activities This severe waste flow generates millions of tons annually and accounts for more than 30% of urban solid waste generation Lu et al 2017a The overwhelming amount of C&D waste takes up significant land resources Marzouk and Azab 2014 The leachate of
Proper management of Construction and Demolition waste and recycled materials including the correct handling of hazardous waste can have major benefits in terms of sustainability and the quality of life But it also can provide major benefits for the EU construction and recycling industry as it boosts demand for C&D recycled materials
Population growth continuous industrial development construction of infrastructure and house building activities create huge amounts of construction and demolition C&D waste C&D debris generally consists of asphalt concrete brick dirt wood metal wallboard roofing and insulation materials plastics cardboard glass and
The construction and demolition waste generated is about 530 million tonnes annually The Ministry of Environment Forest and Climate Change notified the Construction & Demolition Waste Management Rules 2016 on 29 March 2016 The rules are an initiative to effectively tackle the issues of pollution and waste management
Solid waste production must peak this century without drastic action population growth and urbanization will outpace waste reduction warned by Hoornweg et al 2013 A stark example of this prediction occurred in Shenzhen China on 20 December 2015 where an unstable deposit of construction and demolition C&D and other wastes catastrophically
The recycling of construction and demolition waste C&DW is significant for both environmental protection and sustainable development However the dynamically evolving market environment poses new challenges to C&DW recycling As C&DW recycling is increasing in scale and the market for recycled products is developing the effectiveness of
Therefore the use of recycled aggregate from construction and demolition waste instead of conventional aggregates has a double environmental advantage it decreases the consumption of natural resources and reduces the land needed for waste disposal Thus in the last decades many researches have been conducted to analyse the feasibility of
Along with the acceleration of urbanization a large amount of construction and demolition waste CDW has been generated from construction related activities [11] [26] Direct landfill without any treatment was the most common way to dispose of the CDW in the past often wasting enormous valuable resources causing severe environmental problems [23] [37]
Construction and demolition waste is potentially significant in the production of construction materials Geopolymers on the other hand provide a unique opportunity for these waste materials to undergo a chemical reaction which may create polymeric chains of aluminosilicate when in touch with alkaline metals In addition considering the
Construction and demolition waste constitutes a large fraction of all the waste generated in Europe Its specific impact can be considered rather low but the large generated volume and embodied resource makes this waste stream an important focus of current European policies The European Commission has proposed new targets and goals for this
The relevant credits aim to encourage and reward management practices that minimise the amount of construction and demolition waste from base building and/or interior fitout works that is disposed to landfill To address this the credit requires the use of waste contractors and waste processing facilities that have been independently verified
Population growth continuous industrial development construction of infrastructure and house building activities create huge amounts of construction and demolition C&D waste C&D debris generally consists of asphalt concrete brick dirt wood metal wallboard roofing and insulation materials plastics cardboard glass and
Construction and demolition waste CDW is one of the largest contributors to global waste streams simultaneously posing significant environmental and resource management challenges The management of CDW particularly its potential for energy recovery and industrial symbiosis has garnered increasing attention as part of a circular economy approach This
