thanks for reading!
What happens after the PSLE? At Yishun Primary School, learning continues for our Eco-stewards — outside the classroom!
In line with the SustainAble ALP helmed by the Science department, our Primary 6 Eco-stewards were given the opportunity to pilot two composting methods - black soldier fly (BSF) larvae and eco-enzymes. First, they collected leftover food and fed them to BSF larvae. In addition, they deposited food waste into a composting bin and layered it with cocopeat (derived from coconut husks).
Applying both methods at the same time enabled our students to sharpen their observation skills and make insightful comparisons - competencies they could use to thrive in the future. They even got to interact with a group of Johor educators who came specifically to observe them in action. Most importantly, they were glad to help transform food waste into fertiliser, which goes to show that no Yishunite is too young to make a difference to the environment!
Love this! P6 kids doing real systems thinking, not just textbook.
BSF larvae is genius - turns food waste into protein (chicken feed/fish feed) in like 10 days, way faster than traditional compost. And eco-enzymes from fruit peels is low-cost circular economy.
The comparison method is key - BSF = fast protein loop, cocopeat bin = slow soil amendment. Kids learn tradeoffs early.
In my village we do similar with cassava peels + black soldier fly for poultry. Zero waste.
Great to see Yishun Primary doing SustainABle ALP properly. Hope they track weight diverted from landfill - kids love seeing real numbers!
Did Johor educators adopt same for their schools after observing?
