Tackling food waste is considered as a critical aspect under Singapore’s Zero Waste Masterplan. This is because food waste contributes to a high generation tonnage but has a low recycling rate. In 2020, 665 million kg of food waste was generated in Singapore yet only 19 per cent of the food waste was recycled. The other 80% was disposed alongside general waste at Waste-to-Energy plants for energy recovery. It is thus important to explore how waste can be better managed. Additionally, Singapore relies heavily on food imports (90%) and imported feed. This is where it is key to explore ways Singapore can fulfil nutritional needs locally. Brainstorming and implementing ways to extract value from food waste in a circular manner is useful to boosting food security.

Residents are encouraged to contribute their food waste such as vegetable cuttings, fruit peels, carbohydrates and meats to feed the black soldier fly larvae. Any unsuitable food scraps such as durian husks will be separated out by volunteers who manage and sort out the food waste. The black soldier fly larvae serve as decomposers in which frass, a by-product, is excreted from the larvae and are good fertilisers for the vegetables growing in the vertical farm. Simultaneously, the nutrient-rich larvae are a good feed for the tilapia in the fish farm. The fish and vegetable products harvested will eventually be sold to residents using their 'green currency' which they have earned through their food waste contributions. As such, this completes the circular ecosystem. This pilot project is a collaboration between commercial partners such as Otolith Enrichment Group and government agencies such as Singapore Food Agency in Singapore.

This initiative aims to strengthen Singapore’s local food resilience, particularly to produce more food (30% by 2030) and reduce food waste. In September 2021, it has been reported that more than five tonnes of food waste has been used in their ecosystem as compared to being incinerated. The project has also been useful to raise awareness on food security and food waste, while encouraging residents to inculcate good habits. Feedback from local residents have been positive so far and the Tampines Town Council is planning to replicate this project to other parts of the neighbourhood, in hope of becoming a model Eco Town in Singapore by 2050. 

Singapore's Zero Waste Masterplan lays out the roadmap for the Singapore society to collectively work together towards a resource-efficient and climate-resilient nation. The Masterplan has a goal of reducing the amount of waste (per capita) sent to the national landfill by 30% by 2030. This is in addition to an existing target of an overall recycling rate of 70% by 2030.
