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 …

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. A survey study was conducted and analysed with multiple correspondence analysis. It was seen that waiting, overprocessing and overproduction …

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 waste is a global problem, including in New Zealand where it makes up 40–50% of landfill waste. ... the study identifies the design features that have the greatest influence on ...

Proper management and disposal of wastes will reduce pollution in stormwater discharge from any construction site. Good waste management practices include properly locating refuse piles, covering materials that stormwater discharges might displace, and preventing spills and leaks from hazardous materials.

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 ...

For example, over 600 million tones construction waste has produced in the USA [1], [2]. Concrete is one of the most widely used building materials, the main feature of which is cheapness in making raw materials. The use of concrete can be seen in all civil works of the building family, roofs, power plants, roads, etc. [3]. Due to the limited ...

The sixth cluster named "construction project" (silhouette score = 0.902), mainly focused on the critical design factors and management practices that can influence the minimization of waste in construction projects (Ajayi and Oyedele, 2018).

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.

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.

influence construction waste generation are workers' m istakes/errors leading to rework, poor attitudes of workers, shortage of skilled workers/use of unskilled, poor workmanship, and lack of ...

Journal Article: Influence of construction and demolition waste management on the environmental impact of buildings ... (End of Life) life cycle stages are adjusted to several waste/material management options. Unlike most LCAs, the approach is 'top-down' rather than 'bottom-up', which usually involves large amounts of …

Construction and demolition wastes (CDWs) are not normally a concern of citizens who directly generate and deal with …

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.

Natural disasters, new urbanization, and urban renewal activities generated a large amount of construction and demolition waste (C&DW), and managing C&DW has become an urgent problem to be solved in the construction of "Zero-waste cities." Based on the calculation of C&DW generation in China from 2005 to 2019, this study explored …

1. Introduction. The construction industry is one of the largest and most active sectors in Europe. It consumes more raw materials and energy than any other economic activity and generates construction and demolition waste (CDW) accounting for 25–30% of all waste generated in the EU (Di Maria et al., 2018; European …

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.

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 …

These operations produce an enormous quantity of waste products that are detrimental to the environment, requiring an efficient method of waste management. Construction and Demolition Waste ...

Despite this, there is still a long way to overcome the worldwide problem regarding the excessive waste generated from construction, renovation, and demolition activities, defined as construction and demolition waste (CDW). In the European Union, for instance, approximately 30 to 40 % of urban solid waste comes from the construction …

Based on the analysis and it can be concluded all of influence variable of construction waste management performance is valid and reliable with the rank order of variable following these. x Asset is an important factor to support the construction waste management activities with availability operational of construction waste 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 …

A waste disposal lens was used to explore the factors that influence the environment and human health impacts (pH, gypsum and organic content, size fraction, atmospheric exposure and liquid ...

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."

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.

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 …

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.
