Proposed close-loop food waste management in urban wet market

Through analysis of food waste samples collected from Pasar Chow Kit, the organic wastes are identified as primarily comprised of undesired parts trimmed off and discarded produce to fulfil the demand for freshness. The thesis introduces a second life for food waste by recycling it into biodegradable packaging and cutlery, which can be utilized within the market itself. To achieve this goal, the thesis devises integrating markets and food waste processing within the market, allowing the process to be conducted on-site. This approach creates a closed-loop food waste management within the market ecosystem. Three essential principles have been identified to motivate public’s recycling intention. The first principle highlights accessibility, ensuring convenient food waste separation and collection through user-friendly facilities. The second principle emphasizes system efficiency, by implementing of visible processing lines, commodity systems and enforcement application design to instill confidence and encourage long-term recycling behaviour. Third principle leverages education and social influence, through providing accessible information and habit-formation settings to promote a positive attitude towards recycling.

Vertical extension of market’s streets

In the redesign of Pasar Chow Kit, the project maintains the market’s street-like characteristic to respect its existing functionality. The new Pasar Chow Kit is envisioned as a vertical extension of streets, allowing waste processing to occur on different layers. This creates a continuous walkway where market stalls can be conveniently browsed alongside while providing a vantage point to observe the processing activities. Overall, the program integrates revaluing, recycling and learning activities to encourage food waste recycling awareness in Pasar Chow Kit. The proposed system encompasses various components, including waste collection, sorting and distribution, wastewater treatment, production lines, waste-to-energy plants, and vertical gardening. Furthermore, the thesis aspires to preserve the traditional identity of wet markets as vital components of the nation’s food retail sector. By effectively transforming waste materials into valuable resources, this initiative fosters a more sustainable market ecosystem, creates economic opportunities, and upholds the cherished attribute of produce freshness that wet markets are renowned for.
