Material Flow Analysis of Plastic Waste for Circular Economy Potential: A Case Study of Wijaya Kusuma and Sidomakmur Waste Banks in Metro City

The volume of plastic waste in Metro City's landfill continues to rise, and by 2022, it is expected to reach capacity within two years. Waste banks are a crucial solution to reducing waste. This research aims to identify existing conditions, analyze the effectiveness of plastic waste reduction, assess the flow of waste materials, and measure the circular economy potential at the Wijaya Kusuma and Sidomakmur Waste Banks. Data were collected through interviews and observations and then analyzed using Material Flow Analysis (MFA), gap analysis, and descriptive analysis. The results show that the effectiveness of plastic waste reduction at the Wijaya Kusuma Waste Bank is 0.006%, and at the Sidomakmur Waste Bank is 0.007%. The STAN application facilitated MFA by integrating customer data through distribution. Based on circular economy potential, Wijaya Kusuma Waste Bank excels in value addition from plastic processing into plastic pellets. In contrast, Sidomakmur Waste Bank excels in managing waste volume and supporting processing facilities.
