Waste minimisation can be considered as one of the most effective sustainable strategies for managing CW. This suggests that waste must be reduced before it is produced. While waste can be minimised throughout the construction processes, it is often significant at the planning phase where a lot of decisions are made.

Despite the relatively benign characteristics of construction and demolition waste, its mismanagement can result in considerable harm to human health for 200 million workers and those who live and work in proximity to construction and demolition activities. The high number of workers classified as informal, results in a large unregulated and vulnerable …
Our existing wastewater treatment systems allow us to "flush it and forget it," avoiding the complex reality of wastewater pollution. Ignoring this critical issue leads to dangerous consequences, some of which we are already seeing like closed beaches, collapsed fisheries and algal blooms that suffocate aquatic life.
The construction sector is the second-largest consumer of plastics with a volume of some 2.6 million tonnes used in 2017. However, proper guidelines for the recycling of plastic building products are still lacking, and recycling volumes are not recorded adequately. These are the findings of a recent study by the German …

Hazardous waste, by definition, has the potential to negatively affect human health and the environment, which is why it is so strictly regulated. Hazardous wastes are either specifically listed as hazardous by EPA or a state, or exhibit one or more of the following characteristics: ignitability, corrosivity, reactivity, or toxicity.
The current production and consumption models of building materials are causing severe environmental and social problems worldwide. In this sense, construction and demolition waste (CDW) are part of the problem and can be part of the solution, particularly in developing countries where the construction industry is growing very rapidly. Although …

The construction industry generates many environmental pollutants, such as noise, air pollution, solid and liquid waste, water pollution, harmful gases, and dust (Adnan et al. 2014).It is classified as the world's largest consumer of raw materials, the highest energy-consuming sector, reaching up to 36% of the total energy consumption, and one …
Construction and demolition (C&D) activities generate a large amount of waste and have significant impacts on the environment. Thus, it is necessary to implement C&D waste management (WM), which ...
The improper management and disposal of construction waste can have severe environmental and health consequences. Construction waste includes a wide range of materials such as concrete, wood, metals, plastics, and packaging materials. These materials can end up in landfills, taking up valuable space and contributing to …
An optimized construction site waste management plan. As a global reference for waste recycling and management, we provide our customers with the guarantee that all their site waste will undergo compliant treatment. This procedure involves several steps: Site waste removal in special containers; Waste identification and weighing
The result showed that construction waste becomes a major challenge for almost 95.71% of ongoing construction projects. However, only 57.14% of the construction companies have recorded and ...
Construction waste recycling has a wide range of environmental consequences that go beyond trash reduction. The protection of natural resources is one of the key environmental benefits of
This construction waste is generated by a few factors, including the design, management workers, site condition, procurement, and external factors (Nagapan et al., 2012). Despite several ...
Recycle. Recycling is crucial in the effort to prevent valuable materials from ending up in the landfill, with the potential to turn 100 percent of non-hazardous waste back into new construction products. The key to successful recycling is to segregate waste as you go, using different skips or containers for different materials.
Construction waste, such as concrete washout, is under scrutiny from environment agencies around the world, largely due to its heavy-metal content, notably chrome. With the rate of construction unlikely to slow down, there will be no let up in the quantity of concrete washout produced. This is why Watson Marlow Fluid Technology …
It is imperative that construction waste be controlled and managed effectively to reduce the negative impacts on the environment. There are various factors that cause waste, so this study aimed to …
Tips on putting a waste-management and recycling program together to minimize the consequences of construction and demolition debris on the environment On a national scale, total building-related construction and demolition (C&D) waste is estimated to be 135.5 million tons — a figure that represents, at 30 percent, the largest …
Construction and demolition (C&D) wastes are considered the major wastes that are produced by the construction and demolition industries. Construction and demolition waste may include packaging material and land-clearing debris. As a result of disposing of such wastes, there is a minute impact to the environment.
2.1 Life cycle assessment. The environmental consequences of a CDW management strategy must be thoroughly evaluated prior to making a decision (Rosado et al., 2019).In many countries, the use of LCA to evaluate the environmental impacts of waste management systems for construction and demolition is increasing (Bovea & Powell, …

1. Reducing and reusing leftover materials. Accurately calculating the amount of materials needed for each project is a proactive way of reducing waste and eliminating waste treatment costs as well as unnecessary overheads. Having a well organised and up to date inventory of materials in stock can also help avoid over ordering.
