The improper disposal of plastic waste, especially high-density polyethylene (HDPE), is a significant environmental challenge worldwide. To tackle this issue, we propose a Neighbourhood Adopted Model (NAM) that utilizes sustainable HDPE recycling and upcycling programs to rejuvenate our neighbourhoods. The NAM model requires voluntary participation from community members to maintain their surroundings while reducing plastic waste in landfills, waterways, and other natural habitats. Implementing the NAM model requires cooperation from various stakeholders, including residents, local businesses, government agencies, and non-profit organizations. Effective communication and outreach activities can encourage participation and raise awareness of the harmful effects of plastic waste and the benefits of recycling and upcycling programs. This study evaluates the future challenges of the adopted model and provides recommendations for reducing plastic waste in our neighbourhoods. The findings of this study can inform policymakers and practitioners in developing and implementing sustainable HDPE recycling and upcycling programs to combat plastic waste.
