Construction waste generation in Malaysia construction industry: illegal dumping activities

This nowadays an increasing number of construction projects in Malaysia have contributed to the production of construction waste which has had a negative impact on the environment, especially through illegal dumping. The increasing number of illegal dumping activities is a sign that construction waste management needs to be examined. To date, a comprehensive criterion for construction waste management, in developing countries is still not clearly defined. Therefore, the objectives of this paper are to investigate current illegal dumping activities, and identify the challenges towards reducing illegal dumping activities in the Malaysian construction industry. Hence, this research conducted interviews with 20 expert stakeholders related to construction waste management in order to scrutinise illegal dumping activities in Malaysia. The data from these semi-structured interviews were analysed by content analysis. The findings are used to determine the current challenges for reducing illegal dumping activities in the Malaysian construction industry. The elements in the current findings are potentially to improve construction waste management in order to archive the proper construction waste management. Finally, this findings will help to identify strategies to reduce illegal dumping activities and to enhance challenges towards reducing illegal dumping activities in the Malaysian construction industry.

Structured Questionnaire

Construction waste generation has been perceived as a crucial issue that has critical consequences on the project effectiveness and ecological effect of the construction industry. The key objective of the current research is to identify the root causes of material construction waste generation in Malaysia. A well-structured questionnaire was designed based on the 52 identified root causes of material waste generation. The developed questionnaire was distributed to 35 highly experienced in Malaysian construction industry experts. The collected data was analyzed by the use of mean score analysis. The top identified root causes are poor supervision during the construction stage, lack of efficient site management, last minute changes, cutting uneconomical sizes of materials, and constant design changes during the construction period. The initial findings will aid construction practitioners to focus on these root causes in order to reduce the material construction waste generation at construction sites.

Frame Work

Construction waste generation and handling issues have been in focus to achieve sustainable goals. Considering the growth of construction in India, it is appropriate to link generation of construction waste with the growth. It measures to minimize and handle the construction waste are not developed and efficiently adopted, then it may threat for environment. In this research study, Residential construction case studies have been referred to identify the quantum of waste and source of wastage on the projects. Based on the identification of major waste generation on site, how the mitigative steps has been taken that also included in the form of frame work for minimization of waste on the site.

Construction Procedure

The construction sector is among the fastest growing sectors in Malaysia; it consumes a vast amount of natural resources and produces a massive volume of construction and demolition waste. The waste is collected in a decentralised manner by sub-contracted companies. It is challenging to obtain reliable information on the amount of construction waste generated, because it is hard to determine its exact quantity and composition. Therefore, this study proposes a quantitative construction waste estimation model for residential buildings according to available data collected from the Construction Industry Development Board, Malaysia. In the development of this model, a theoretical investigation of the construction procedure and the construction waste generation process was conducted. The waste generated rate was determined as 25.79 kg m−2 for new residential constructions, which translates into about 553,406 t of anticipated waste annually.

Construction waste is a material of waste or excess building materials that are not used either in the original or debris from construction, structural repair, and improvement work, house demolishing, buildings and other structures. Wastes are from excess building materials from dredged material and stumps of structural repairs, improvements and work to destroy sidewalks, homes, commercial buildings and other structures. Construction waste also refers to soil, rock and vegetation removed during land levelling works or civil engineering works and works related to road maintenance. Illegal dumping site is places other than permitted facilities to dump waste such as transfer stations and landfills. The objectives of this study are; (1) identify illegal dumping of construction waste distribution in Parit Raja; (2) quantifying the illegal dumping of construction waste generated in Parit Raja and; (3) develop Geographic Information System (GIS) map for illegal dumping construction waste distribution in Parit Raja. In this study the location of the construction waste identified using Global Positioning System (GPS) in smartphone. Then the picture and material of construction waste was taken and identified. After that the volume of construction waste were determined using the pyramidal or rectangular shape measure. For the scattered waste, the weight were taken and converted to volume. Lastly the data was plotted and mapped in the GIS system. This study successfully create a database of construction waste generation in Parit Raja. The benefit of this study is it will help the management of waste in Parit Raja.Keywords:constructionwasteillegaldumping,database,GISsystem

This article examines the complexity of construction waste management in Shenzhen, Mainland China. In-depth analysis of waste generation, transportation, recycling, landfill and illegal dumping of various inherent management phases is explored. A system dynamics modeling using Stella model is developed. Effects of landfill charges and also penalties from illegal dumping are also simulated. The results show that the implementation of comprehensive policy on both landfill charges and illegal dumping can effectively control the illegal dumping behavior, and achieve comprehensive construction waste minimization. This article provides important recommendations for effective policy implementation and explores new perspectives for Shenzhen policy makers.

Construction industry creates a massive amount of waste, which typically ends up in landfills. Canadian construction industry represents 30% of the total municipal solid waste deposited in landfills. Construction and demolition (C&D) waste has created negative socioeconomic and environmental impacts including contaminating ground water, emitting greenhouse gases, and adding more waste to scarce landfills. Literature is cited rework/waste generation due to ambiguity/errors in construction contract documents. Exculpatory clauses in contract documents are included in contractual agreements to prevent contractor claims, which often cause rework. After an extensive contract documents review, these clauses were categorized in to eight major areas. This paper (1) analyses expert opinions on pre-identified contractual clauses; and (2) introduces recommendations to minimize rework and waste in construction projects. It was found that the clauses related to quality, workmanship, and field quality control/inspection have the most potential to generate construction waste.
