Wherever possible, demolition activities should be avoided and in case of strength in-deficiency, strengthening techniques like the use of fibre-reinforced polymer composites may be opted for and when unavoidable, the produced construction and demolition waste should be carefully managed by recycling it.
Construction and demolition wastes (CDWs) are not normally a concern of citizens who directly generate and deal with municipal solid waste (MSW) every day. However, waste from buildings and infrastructure poses both huge management challenges and opportunities to advance a society's sustainable waste and resource management.
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...
Construction and demolition waste (C&DW) arises mainly as by-products of rapid urbanisation activities. C&DW materials have high potential for recycling and reusing.
Builders, construction teams and design practitioners can divert construction and demolition (C&D) materials from disposal by buying used and recycled products, practicing source reduction, preserving existing structures, as well as salvaging and reusing existing materials.
Reducing waste will reduce energy use, minimise degradation of the environment and reduce embodied carbon emissions. This chapter reviews the nature, characteristic and magnitude of construction, maintenance and demolition waste of buildings and their associated embodied carbon emissions.
Learn how to manage stormwater and dust at demolition sites, including developing a stormwater solution prevention plan, best practices for erosion, runoff and sediment control to reduce environmental impacts and …
Sustainable reuse of brownfield properties includes efforts to reduce the environmental impact by reusing and recycling materials generated during building construction, …
As a result, the construction sector is increasingly concentrating on improving waste recycling processes in order to reduce its environmental imprint.
The objective was: To study and evaluate the impacts of current practices of construction and demolition waste management. To determine the parameters that determine the sustainability of C&D waste management strategies. To develop a framework for the evaluation of sustainability of C&D waste management strategies.
The main contribution of this paper is a theoretical framework for the Circular Economy in the construction and demolition sector. The framework is comprised of 14 strategies within the five lifecycle stages of construction and demolition activities.
The overarching aim is to reduce the staggering amount of construction and demolition waste ending up in landfills each year, while simultaneously recovering high-quality …
Construction, demolition, and renovation activities generate a large amount of waste which harms the environment and can have a significant impact on global warming if it is not managed properly [21].
As the demand for materials continues to increase and building lifespans shorten, the construction industry faces mounting pressure to reduce its material and environmental impacts.
A defining feature of a sustainable building is that it reduces environmental impacts significantly. This can include measures to reduce energy consumption and carbon dioxide emissions; minimise the use of resources such as water; reduce the release of pollutants; maximise the use of reclaimed and recycled materials; and promote sustainable travel …
This review looks over the current construction and demolition waste management (C&DWM) situations by scrutinizing the definition, classification, components, …
(1) Background: Globally, numerous development projects are being undertaken to expand and improve urban infrastructure facilities, which result in around 30% to 40% of construction and demolition (C&D) waste in the total waste generation. Due to its detrimental impacts on the environment and human health, several researchers have …
For more information on specific organizations that buy and/or sell reusable or recyclable C&D materials, view our list of organizations working to reduce the disposal of construction and demolition materials.
An assessment of the impacts of demolition, earthworks, construction and trackout. In this Guidance, specifically the air quality impacts. Demolition Any activity involved with the removal of an existing structure (or structures). This may also be referred to as de-construction, specifically when a building is to be removed a small part at a time.
Construction and demolition waste (C&DW) as a direct consequence of rapid urbanization is increasing around the world. C&DW generation has been identified as one of the major issues in the construction industry due to its direct impacts on the environment as well as the efficiency of construction industry.
Here at GoContractor, our focus is on helping companies move their construction safety training and onboarding online. With that said, we're always looking at ways to make construction better, and in this article, we explore the environmental impact of construction, and what the industry can do to improve their environmental footprint.
CDW is generated along the whole life cycle of construction and demolition activities. It should be noted that the FU corresponds to the reference flow of one tonne including non-targeted material that may end up with the selected fraction due to demolition and collection activities.
As the demand for materials continues to increase and building lifespans shorten, the construction industry faces mounting pressure to reduce its material and environmental …
ficantly support implementing more market incentives to reduce waste disposal. They also indicate that investment in technology and infrastructure, sustainable procurement and landfill levies are three ajor influential factors that have a significant impact on market development. The research findings can inform decisions and policies develo
This Guidance is intended to assist with the control of nuisance dust and fine particle (PM10) emissions from construction and demolition activities. It gives a background on the effects of these emissions on health and the environment and also legislation related to regulating dust and fine particle emissions into the atmosphere, exposure of the general …
Activities such as joint work between designers and builders to reduce the amount of materials used in construction, the reuse of CDW according to its physical and mechanical properties, and an increase in the recycling rate of these materials are essential to reduce their negative impact on the environment, especially in emerging ...
In this regard, the implementation of CE (Circular Economy) has emerged as a potential model to minimize the negative impact of C&D wastes on the environment. However, there are some challenges hindering a full transition to CE in the construction and demolition sectors.
The overarching aim of the practice is to promote a more efficient use of resources, reduce the environmental impact throughout an almost full life cycle, increase confidence in the construction and demolition waste management process and the trust in the quality of recycled materials.
