Singapore's urban policies is effected according to the planning zones set out in the master plan. As such, the interfaces between districts are often neglected and end up segregating the urban fabric. In addition, our transportation network is drawn in accordance to the masterplan, where urban highways and major roads often overlap with the planning boundaries. As a result, urban highways become the demarcation line between districts, disrupting the networks within our society. However, interfaces between districts, at the junction of diverse resources and communities, should be explored as prime opportunities for collaboration.

Tapping on food waste as a common resource, the thesis aims to explore how food waste can be contributed along interfaces between districts to create new collaboration opportunities for civic entrepreneurs. Faced with land scarcity, the rise in food waste is identified as a threat to Singapore’s sustainability where the current rate of disposal exceeds Singapore’s capability to receive and treat waste. Hence, there is a need to push the boundary for more sustainable food waste management. This could be in the form of upcycling food waste into new resources for collaborative food production, idea prototyping and skill-sharing to empower civic entrepreneurs.


Located in between the existing CBD and future greater southern waterfront development, the Keppel viaduct is identified as a major boundary in the existing landscape. It is at the intersection of many communities aside from the CBD - Outram, Bukit Merah and Tiong Bahru. The strategic location of the site enables access to diverse resources in its proximity such as HDB estates, institutions, hospitals and offices.


Hence, the viaduct serves as a key interface to allow for collaboration to happen across the different stakeholders. The thesis proposes to spatialize the Keppel Viaduct as a landscape of collaboration to generate new shared opportunities for local startups from food waste – i.e. carbon capture, community 3d printing, algae farming, bio-energy and building materials.

Idea Prototyping &
Food Experimentation

In addition to converting food waste to bioenergy through anaerobic digestors, carbon captured from spent coffee ground can also be converted into energy to power the shared programs along the viaduct. 3D printing filament would be generated from food waste and fed into the community 3D printers in the city centre, providing a platform for local start-ups to experiment and prototype. The congregation of ideas and knowledge allow cities centres to be hotbeds for innovation as well as  collaboration between existing and new businesses through shared kitchen and food experimentation labs. The produce from farming within the city centre can also be used by emerging F&B startups as low-cost resources. Spent coffee ground would be processed as fertilisers for algae farming, which is a feedsource for shrimp culture.
