Abstract. Ensuring material availability and reducing material waste are two crucial aspects of material management to improve construction project performance …
As construction activities become more intensive in developing countries, increasing improperly managed construction and demolition waste (CDW) brings serious environmental impacts. Recycling is a beneficial way to dispose of CDW that reduces environmental impact and brings economic benefits, especially for concrete. China is the …
Abstract. Poor materials management can have a negative impact on cost as a result of excessive waste, quality and time of work, which will affect project delivery and profitability. A relatively ...
Construction waste causes significant damage since it accounts for about one-third of all refuse nationwide. Recycling construction materials can significantly reduce the environmental impact of the industry. The construction sector takes 50% of raw materials from nature and creates 50% of the total waste.
The impact of construction transport is non-negligible and, according to Guerlain et al. ... BREEAM requires only data collection on the transport of construction materials and waste, under responsible construction practices (BRE, 2016), while LEED requires a reduction in transport, ...
Reduce toxic chemicals and environmental impacts throughout the material life cycle. ... U.S. food loss and waste alone "wastes" 140 million acres of agricultural land, 5.9 trillion gallons of blue water, 778 million pounds of pesticides, 14 billion pounds of fertilizer, 664 billion kWh of energy, and releases 170 million MTCO2e GHG. ...
This paper outlines a methodology for structuring a generic database of environmental impacts on the end-of-life phase of buildings, which can be used at the national level, in accordance with European standards. A number of different options are also considered for managing construction and demolition waste (CDW), as well as for …
The mining industry manages large volumes of tailings, sludge, and residues that represent a huge environmental issue. This fact has prompted research into valorization of these wastes as alternative aggregates for concrete production, embankments, pavement material, etc. The use of mining wastes as a resource for construction presents two …
The study also indicates that project cost overrun, pollution of the environment, reduction in profit and failure of construction firms, excessive …
Our specific objectives are to 1) identify the frequency of plastic waste used in construction reported in the literature, including the source material (i.e., product and polymer types) and end application (i.e., types of building materials and infrastructure), 2) evaluate what is known about the effects, 3) identify whether the practice is ...
12.7.5 Impact of Construction and Demolition Waste on the Soil During Disposal. Table 12.3 summarizes some of the construction-related effects on soil. Waste during the construction phase arises due to misuse or mishandling of materials or due to the procurement of excessive raw materials which are not utilized ultimately.
By using construction waste separability quality evaluation indexes, the identification accuracy of construction waste in the two study areas was determined to be 96.6% and 96.2%, the separability ...
Sourcing materials with low embodied energy can reduce your home's environmental impact. Waste minimisation. Building waste makes up approximately 44% of Australia's waste. The 'three Rs' of waste …
Therefore, an extensive amount of waste materials with harmful impact on the environment is generated which causes a disposal problem (Ulubeyli et al., 2016). Construction Environmental Management can effectively minimize any potential adverse environmental to avoid, minimize and mitigate construction effects on the environment …
Analysis showed that C&D waste recycling could be an effective mitigation option to reduce the risk of landslides; reduce the energy consumption; offset the …
Major factors that have an impact on the system were carefully considered when simulating the long-term effects of reducing construction waste in the construction life cycle of industrial projects during the design phase for two techniques (Design Strategies, Designing Out Waste) in eight main aspects of cost waste, time waste, …
