Abstract
The function of minimization of construction solid waste is to reduce or eliminates the adverse impacts on the environment and to human health. Due to the increase of population that leads to rapid development, there are possibilities of construction solid waste to be increased shortly from the construction works, demolition or renovation works. Materials such as wood, concrete, paint, brick, roofing, tiles, plastic and any other materials would contribute problem involving construction solid waste. Therefore, the proper waste minimization is needed to control the quantity of construction solid waste produced. This paper identifies the type of construction solid waste produced and discusses the waste minimization practice by the contractors at construction sites in Selangor, Kuala Lumpur and Putrajaya, Malaysia.
Highlights
The solid waste problem is one of the most debatable as well as other environmental issues such as problems of haze and air emissions from anthropogenic sources, and water problem both in terms of quantity and quality and indiscriminate dumping toxic and hazardous wastes [1]
The purpose of this paper is to identify the type of construction solid waste at construction sites and determine the waste minimization practiced by the contractors at Selangor, Kuala Lumpur and Putrajaya, Malaysia
Most of the respondents were professionals i.e. quantity surveyor (24%), engineer (20%) and architect (16%) while others are site supervisor (16%), project manager (14%) and site clerk (10%) who involve directly at a construction site. 64% of the respondents have than 5 years working experience in the construction industry
Summary
The solid waste problem is one of the most debatable as well as other environmental issues such as problems of haze and air emissions from anthropogenic sources, and water problem both in terms of quantity and quality and indiscriminate dumping toxic and hazardous wastes [1]. According to GEC [2] solid waste is one of the three major environmental problems in Malaysia. Over 23,000 tonnes of waste is produced each day in Malaysia. In Malaysia, there are almost 1800 rivers, but more than half of the river have been polluted and destroyed because of the improper solid waste management [2]. Amount per capita generation of solid waste varies from 0.45 to 1.44 kilograms per capita per day [1]. According to Formoso, Soibelman, Cesar and Isatto[3], the waste quantity produced are more due to insufficient in managing a waste material as compared to faulty in construction methods. The practice of reuse, reduce and recycle are suggested to minimize waste production by the contractors at construction sites as it could reduce the needs of new resource and cost savings in terms of transportation and disposal of waste materials to landfill [4]
