Construction waste poses a significant threat to the environment. Debris, such as concrete, wood, metals and glass, that is left over can be sizeable and needs to be disposed of. Much of this waste is not reused or recycled and is subsequently redirected to landfills. The environmental impact of construction waste (CW) generation and the shortage of land resources for the creation of new landfills have reinforced the need to find suitable methods to manage construction and demolition materials that generate waste during construction activities.
Waste tends to be generated as a result of improper design, changes in building design, inefficient material handling as well as poor procurement and planning.
Architects need to be mindful of the need to create a building in accordance with its design but also to comply with environmental requirements in a respectful way and this means intelligent design practices.
Ideally, the best management approach to waste is to manage the process so there is no waste to manage. Of course it is impossible to produce no waste at all but it can certainly be minimised. If waste can be eliminated before the project goes to site the need for waste disposal is decreased.
This is where Building Information Modelling (BIM) technology is useful. While BIM is not new, its role in waste management and energy conservation could be used more effectively.
