INTRODUCTION

General

This research is focused on waste minimization in construction building sites that influences the economic. Besides that this study is also intended to identify the methods to reduce the waste in the construction site. In this chapter the basic elements of study are presented. Basically this chapter covers the problem statement, objectives, scope of the study, and significance of the study.

Construction waste can be one of the major impacts to the environment if proper disposal practice is not adhered. As such, a greater concern should be given to the construction waste to reduce its burden to the environment. The product of construction industry that all of variety of waste which occur at every stage of construction activities and practices on site this amount of construction produced have to be taken seriously due to many reasons such as the affecting and danger problem to the environment. It is very important for the person in charge of disposal the construction waste to profit development and sustainable future.

The waste generated by construction operations must to be taken seriously because construction industry contributes a significant waste to the overall waste volume in a country. Today, its importance has a definite impact and becomes essential in the pursuit of productivity goals. In addition to the need to be a well-informed society on waste, it is necessary to effectively communicate and develop adequate understanding on waste minimization. Now waste management is necessary, recycling is one of the best options to convert the waste material into recycled contents and this is one of the important activity in the waste management field.

1.2 PROBLEM STATEMENT

The construction waste has many major impacts to the environment. There is classification methods required in execution of mega projects in Malaysia, commercial building and housing development programmed, construction field produce large amount of construction waste by the construction sector. (Poon, 2007). Construction waste must be balance justifiably with waste disposal because the big amount and different compositions have the possibility to post serious problem and leads to other surrounding impacts. The process involves awareness, cleanliness conservation, and efficient waste management process. To sustain better monitoring of construction waste, the sustainable development must demonstrate benefits rather than sacrifice to the public.

(Teoh Su Ping 2009)

The amount and type of waste products depends on factors, such as the stage of construction, type of construction work and disposal practices on site. Extra construction materials are usually planned due to the lack of consideration given to waste reduction during the planning and design stage to minimize the generation of waste.

The excessive wastage of raw materials, improper waste management and low awareness of the need for waste reduction are common in the local construction sites. Thus, waste minimization is an important area of concern in the implementation of waste management.

Growth in the construction activities generates construction wastage which becomes a serious environmental problem with badly consequences; Most of the construction waste are not recycled but send to the landfills.

(Mohd Nizam, 2010)

The construction waste affect not only on environment it’s also affect to the project cost to the contractors. There are many countries especially the developed countries started to use methods to recycle the construction materials due to its benefits. In this country there is a huge possibility in recycling the construction waste and 'if implemented correctly; will only bring about construction resurgence (Wong W. 2010).

OBJECTIVES OF STUDY

The main objectives of this study are as follow:

To identify type of construction waste material that can be recycled.

To recognize various construction site wastes recycling methods and defining an approach to reduces the waste material in construction site.

To analyze the efficiency of recycling method, in order to reduce disposal effect.

1.4 SCOPE OF THE STUDY

The scope of this research covers the application of construction waste minimization as in practice and study the effect of recycle method of construction waste in Malaysian construction industry building. The area that covered in this study is belonging to Selangor in Malaysia country.

1.5 SIGNIFICANCE OF THE STUDY

This study done due to many reasons, the construction industrial waste grows and need efficient methods to reduce the material wastage that will decrease the impact in the environment. It’s the first reason and the importance one which considered as one of three major environmental problems as construction industrial waste grows. Introducing an efficient method that deals with construction waste and resulted in positive impact to the environmental; therefore we can reduce waste by construction management and get benefit of waste minimization on construction site.

Also in this research we looking how to reduce the construction burden to the landfill and give more life to the landfill. Other reason of this study is how to prevent construction waste by which way and which method to minimized construction waste to give notification by the responsible or supervisor or contractor to the workers in site to work properly and how to prevent the sources of waste.

In addition; this study hopes to convince the responsible that who control or anyone who involved to construction industry like engineers, developer, construction site manager or supervisor and contractor that the best dispose of waste materials is recycling.

With recycling the materials will not give burden to landfill but will give more life to the landfill and will not sent to incinerators just the contractor can sent the materials to recycling center or any recycling companies.

Doing recycling to the materials on site or sent to recycling center will give profit to the contractor or at least will recoup his losses in same time that going to protect the landfill and give it more life.

This is the way Malaysian construction industry can minimized and cut down on landfill site and protect the natural and environment.
