Recycle Evaluation using System Dynamics for Solid Waste Management in Malaysia

Abstract

Solid waste management gained the highest significant attention globally. In Malaysia, the generation of solid waste has increased 4% approximately year by year and an average from 0.8 kg/cap/day to 1.12 kg/cap/day. This trend is in line with the increasing population density in Malaysia especially in urban areas. The exponential growth of economic, urbanization, demographics and changing lifestyles are the key reasons behind the increase in the generation of solid waste. The objective of this research is to develop a system dynamic model for solid waste management in peninsular Malaysia and analyze the recycle evaluation. This method has an ability to handle a complex system and dynamic behavior over time. The result show that model imitate the real system with the validation less than +10% and -10% of acceptance range. This model can assist the decision maker in making efficient decision. The management of solid waste department may holistically measure the alternative action in cost effective and save time. As a result, the recycle rate in Malaysia relatively low and lack of participation from public. Enforcement and engagement from all parties are needed in order to achieve a sustainable environment in future.
