Reuse and Recycling Opportunities and Demolition US EPA

Local recycling markets may exist for non-hazardous demolition materials and land-clearing debris. For example, wood, metals, concrete, asphalt, brick and block are highly recoverable in many locations. Some non-hazardous materials can be reused on-site, in accordance with state and local requirements. A demolition recycling specification thatCurrently, construction and demolition waste (CDW) is among the largest in EU, estimated to be 25–30% of all generated wastes [1]. The EU waste directive 2008/98/EC requires member states to recycle 70% of their non-hazardous CDW as raw materials by 2020. However, the current recycling rate is only approximately 46% [[2], [3], Recycled construction and demolition waste as a possible

This chapter explains the main characteristics of construction and demolition waste (CDW). Important topics are the definition of this material as well as its composition: concrete, bricks, metals, glass, asphalt, wood, etc. Management of construction and demolition waste is discussed. Valorization plants for recycling of CDW are describedWhile earlier demolition concepts do not consider any possibilities of re-use or recycling of the debris, the modern concept with its four phases separates the debris at any stage of the demolition (Kamrath and Hechler, 2011b).Nevertheless, the recycling-rate depends on the materials used in construction (Röbenack et al., 2007).During the Demolition techniques and production of construction and demolition

Life Cycle Assessment on Construction and Demolition

Life Cycle Assessment (LCA) is considered an innovative tool to analyze environmental impacts to make decisions aimed at improving the environmental performance of building materials and construction processes throughout different life cycle stages, including design, construction, use, operation, and end-of-life (EOL). Therefore, Construction and demolition waste (CDW) accounts for at least 30% of the total solid waste produced around the world. At around 924 million tons in the European Union in 2016 and 2.36 billion tons in China in 2018, the amount is expected to increase over the next few years. Dumping these wastes in sanitary landfills has always been the Circular Economy on Construction and Demolition Waste: A

Circular Economy of Construction and Demolition Waste: A

Whilst the hierarchy of waste minimization places recycling third after reducing and reusing, a 2019 study by the Auckland City Council on the diversion of demolition waste found that recycling would still hold great benefits . The study concentrated on the cost-benefit-analysis of diverting demolition waste from landfill for a new housing The results revealed that the disposal cost of demolition waste (1.04 KWD/m 2) was lower than the disposal cost of construction waste, as presented in Table 2. The disposal costs of construction waste were 1.357 KWD/m 2 for residential projects and 1.785 KWD/m 2 for commercial projects.Recycling Free Full-Text Evaluation of Construction and Demolition

Introduction. Construction and demolition (C&D) waste is one of the largest waste flows in the world. Several research investigate that C&D waste has reached 30–40% of the total solid waste because of the large scale construction and demolition activities resulting from the accelerated urbanization and city rebuilding (Akhtar and Sarmah, The construction and demolition phases were considered for recycling potential assessment, while the operational phase was examined for assessing the advantages of energy recovery.
