Calculations actually show an increase (generally less than 5%) in most impact categories for the Materials and End of Life stages because of extra transportation needs. However, core material separation in demolition operations and its recycling and/or reuse does bring environmental benefits. A reduction of around 77% has been estimated in the ...

Construction waste (CW) is damaged materials generated during the construction process and considered the most significant contributor to landfills worldwide (Ibrahim et al., 2010). Specifically, CW continually contributes approximately 16%–60% …

Construction and demolition (C&D) waste is a novel, widespread environmental stress that negatively affects environment, organisms and ecosystem. Yet effects of cumulative consequences of C&D waste on the fitness and community structure of most underground insects remain unclear. With relatively sessile life underground …

The investigation shows that the recycled concrete with building waste composite powder has poor frost resistance, and the anti permeability performance is lower than that of ordinary concrete. Based on this, this study analyzes the influence of construction waste composite powder material on frost resistance of concrete. 2.

The research seeks to experimentally evaluate the utilisation of construction and demolition waste (CDW) in cement-treated sub-base, incorporating a blend of fly ash and lime. This involved mixing CDW-based recycled concrete aggregates (RCA) with natural aggregates in varying proportions (25%, 50%, 75%, and ) with a …

As an example, the climate change impact factor of 271 kg CO 2 eq/m 2 for the generalized building Materials stage was obtained as the result of a 7.3% share of the 3700 kg CO 2 eq/m 2 global average climate change impact presented in Table 1.All other Table 2 figures were obtained in the same way.. The average life-cycle shares are …

The influence of CW-RM on pervious concrete performance are reviewed. ... Using construction waste recycled materials (CW-RM) to prepare pervious concrete can not only effectively sell the urban solid waste of construction waste, reduce environmental pollution, but also provide a key material for the construction of 'sponge …

Influence of Construction and Demolition Waste Incorporation in Concrete Antônio Macedo, Euzebio Zanelato, André Manhães, Afonso Azevedo, Markssuel Marvila, Jonas Alexandre, Sergio Monteiro and Lucio Petrucci Abstract The construction industry is the human activity that consumes the most natural resources.

1. Introduction. In recent years, the concept of circular economy has gained increasing attention from both academia and industry, including in the construction sector [1], [2], [3].Despite this, there is still a long way to overcome the worldwide problem regarding the excessive waste generated from construction, renovation, and demolition …

The most common method of handling construction and demolition waste (CDW) is recycling; this produces recycled aggregates that can replace natural aggregates in various applications while ...

Therefore, innovative approaches to channel plastic wastes away from landfills are. imperative. In this mini-review, recycling of plastic wastes to materials useful in the building and con ...

Although the area of a building is the key factor determining 74.8% of the variation of construction waste generation, the employment of labour-intensive techniques in the study area means that human factors such as the contractor's attitude and behaviour towards waste management, exert a key influence on waste generation.

Description. Construction staff manage and dispose of building materials and other construction site wastes to reduce the risk of pollution to stormwater. Practices such as trash disposal, recycling, proper material handling, and spill prevention and cleanup measures can reduce the potential for stormwater flow to mobilize construction site ...

The results indicate that the most significant factors affecting the generation of construction wastes are "quantity take-off error by contractor," "unforeseen incidents damaging site and/or completed works," "design errors," and "extreme weather conditions damaging completed works."

Moreover, enhancing the industry-wise administration system and practitioners' dedication to the issue can be an option to avoid illegal construction waste dumping. The results of this study serve to elucidate the influential factors and offer practical implications for addressing the issue of illegal dumping of construction and demolition …

Abstract. Rapid growth in construction activities increases construction waste problems around the world. Construction waste gives a negative impact to the environment, costs, time, productivity and social of country. To reduce these negative impacts, it needs a comprehensive understanding of the construction waste generation and management.

In recent decades, because of the massive destruction of old structures, a large amount of construction and demolition (C&D) waste has been produced. These waste materials have the greatest volume and weight among solid waste with many environmental problems. Reusing them in concrete as substitute to aggregates is …

Life cycle assessment (LCA) modelling of construction and demolition waste (C&DW) management was carried out. The functional unit was management of 1 Mg mineral, source separated C&DW, which is either utilised in road construction as a substitute for natural aggregates, or landfilled.

This approach is generally adequate when information on building quantities (bill of quantities), final drawings and appropriate construction products environmental impact databases is available, bearing in mind the location of the buildings in relation to building materials suppliers and waste management operators.

A study conducted on 30 construction sites revealed that concrete (12.32%), metal (9.62%), brick (6.54%), plastic (0.43%), wood (69.10%) and others (2%) are some of the significant categories of …

The reverse logistics (RL) performance of construction and demolition waste (C&DW) differs significantly between countries. Although some countries are successfully circular, other countries are still far behind; with C&DW being largely directed to landfills or being illegally dumped.

Critically considered waste materials generated at different stages of building. • Influence of waste materials on building environmental impacts was comprehensively evaluated. • About 20% GHGs emission was underestimated for avoiding these in building assessment. • Adopting resource recovery principle can lead to 37% …

This study purposes to determine which types of waste are influenced and reduced by the Lean principles and BIM functions that occur during the construction phase.

This study aims to determine which types of waste that occur during the construction phase are influenced and reduced by lean principles and building information modelling (BIM) functions.
