| Abstract | Sri Lanka's economy has mostly had strong growth rates in recent years resulting progres- sion in the construction industry after the civil war has ended in 2009. Physical waste gen- eration is an inevitable consequence of construction activities. In many developed countries, including some of the countries in Asian region has effective construction waste manage- ment systems. However in Sri Lankan construction industry, a proper construction waste management system is non-existent. Considering the residential and commercial construc- tion projects in Western and Sabaragamuwa provinces in Sri Lanka, this research study has pointed out the problems occur due to construction waste and the benefits of construction waste management. Moreover, what are the mostly wasted materials, existing systems to manage them are found out with analysing the causative factors effecting construction waste. The causes of construction waste are categorized into seven parts. Surveys and interviews carried out in this study have revealed that, formwork timber, timber, plywood, cement and bricks are the mostly wasted materials. Mostly minimized materials are timber and glass, mostly reused materials are coarse aggregate and rubber, mostly recycled materials are pa- per and plywood and mostly disposed materials are cement blocks and cement mortar. In addition, financial problems are the most frequent problem occurred due to construction waste. Cost saving and profit minimization is the greatest benefit due to construction waste management. Insignificant budget for handling waste is the most frequent factor hindering the practice of construction waste management. Moreover, correlations between company grades, stories of building and project costs with causes of construction waste, problems due to construction waste, benefits due to construction waste management and factors hinder- ing the construction waste management were found. Finally recommendations are given to government, contractors and clients to make waste management a profitable venture. |
