Plastic waste has emerged as a pressing global environmental concern, with Malaysia being no exception. Environmental problems linked to plastic waste has served as a catalyst for transitioning towards a circular economy (CE). Presently, CE is a widely embraced concept for future sustainable development, advocated not only by the European Union (EU) but also other countries including China, Japan, Germany, France, Canada, the Netherlands, Finland, and others. In fact, CE offers a viable alternative to the current linear system by focusing on increasing the reuse or recycling of plastic materials within the system. However, in Malaysia, the absence of comprehensive legislation tailored to the CE principles suggests a gap in the regulatory policy framework for supporting the transition towards a CE for plastic waste. Through the CE concept, a systematic literature review (SLR) was conducted. A final set of 21 papers were selected for examining potential regulatory policies to plastic waste CE by identifying existing policies and laws in various countries and their prospects for implementation in Malaysia. The findings may provide an overview of the laws and policies that support CE implementation, and they could also serve as a guide for Malaysia in determining which policies should be implemented.
