2. Segregation

Segregation is another method that can be used to prevent and reduce construction waste. Segregation is a process implemented at source whereby waste is segregated into specific types of materials. The aim of segregation is to increase the potential of construction waste material for re-use and recycling, and indirectly, to reduce the disposal of waste to landfill.

Preparing for re-use
The construction materials generated should be re-used on site or salvaged for re-use to the greatest extent possible. Disposal should only be considered as the ultimate alternative. Some examples under this initiative are shown in

Preparing for re-use
The construction materials generated should be re-used on site or salvaged for re-use to the greatest extent possible. Disposal should only be considered as the ultimate alternative.
Re-use of construction waste generated from renovation and demolition activities using the deconstruction method is highly recommended. Deconstruction is a process whereby building components are dismantled carefully to salvage components for re-use and recycling.
This technique also can be included in the method statement by determining the specific components to be used. Indirectly, this technique will increase the re-use and recycling rate of the project.
There are several benefits derived from the deconstruction method as follows:
• Encourages the re-use of construction materials - re-use costs less than disposal
• Reduces the negative impact on the environment from the extraction of natural resources
• Reduction in the cost of transporting, and energy used in converting, raw materials to be used in new buildings and …show more content…

Incineration, which has been in the hierarchy in the first stage of the evolution, has been criticized due to the cost (Rasmussen et al., 2005) and impact to the environment (Connett &Sheehan, 2001).
Therefore, in the recent hierarchy, incineration has been pulled out from the hierarchy and replaced by treatment (Gertsakis & Lewis, 2003); or thermal treatment (Sarifah Yaacob,2009).
Waste minimization, reuse and recycling practices are limited in the construction sector and natural resources required as building materials are available at relatively low cost (Begun et al 2009). In addition there is no mandatory requirement for construction companies to practice sustainable resource and waste management and illegal dumping is still an issue for the authorities (Begun et al 2009).
In support to national policy, CIDB has reinforced the industry’s commitment to sustainable development and an environmentally responsible industry in the “Construction Industry Master Plan” (Construction Industry Development Board, 2007) and is continuing to educate the industry’s key players with series of training courses, workshops and awareness raising events. In addition, the introduction of the GBI (Green Building Index) is providing a framework to design and construct green sustainable buildings and raises awareness within the
