Project T.E.S. aims to encourage behavioural change to reduce and recycle the amount of food-waste at YPS. Primary 1 to Primary 6 pupils, staff and canteen stall holders are involved in the segregation and recycling of food-waste during the 3 recesses. Through this experiential hands-on closed-loop process to food-waste recycling, our pupils will experience and empathise with the process of food-waste recycling. The school’s on-site food-waste composter machine converts food-waste into compost, which is later used in our school gardens and Science projects.
The daily collection of food-waste is monitored by the Science Department. It is heartening to note that the amount of food-waste collected over time is on a decreasing trend; which is indicative of the pupils’ commitment to reducing food waste by ordering only what they will eat. This project also contributes to National Environment Agency’s (NEA) national waste management strategy to work towards the goal of Singapore becoming a Zero Waste Nation.

For example, our P6 pupils have a fun-filled afternoon learning about Science through an amazing outdoor lesson at the Science Center’s Eco-garden. They spend their afternoon looking for various life forms, such as microscopic algae, pond skaters and dragonfly nymphs. The pupils learn field techniques to catch and observe a variety of aquatic organisms which make up the pond community. In the process they also learn about relationships between organisms (e.g. food web) in the pond ecosystem.

As part of Yishun Primary School’s outreach efforts, the Science department conducted an outreach themed upon upcycling, recycling and waste minimization. Using posters, displays and brochures, members of the public were exposed to the purpose and ways they could affect change in their own lives to help support environmental conservation. Pupils were also able to leverage on this platform to showcase Science projects completed over the year to highlight green habits and promote green consumerism.
