Support the Worm Project
Help us build The Worm Project
Every week, local cafes send hundreds of kilos of coffee grounds and food scraps to landfill, where they release potent greenhouse gases. In partnership with the Johnson Ohana Foundation, we are establishing a commercial-scale worm farming system at Green Thumb Farm to turn that waste into rich soil that grows food for the community.
Farm Friends
We invite you to support our mission and be a part of a change for good.
How Will the Worm Project Work:
1. Food waste from our community is collected at Green Thumb Farm.
2. It is transformed into nutrient-rich castings through the high-capacity worm farming system that we will install at the farm.
3. These are returned to the soil to grow fresh, healthy food again.
Why it is Important:
Each year, we will divert around 7 tonnes of café food scraps and coffee grounds from landfill. The Impact:
- We will stop 13.87 tonnes of CO2 and 548kg of methane from entering the sky. That is the same impact as taking 3 passenger cars off road for a full year!
- We will turn "scraps" into 2,000 litres of microbe-rich castings to fertilize our community crops.
- The system becomes a hands-on learning site where local schools and families see the circular economy in action.
We Need Your Help
To bring The Worm Project to life, we need to install a commercial worm farm at Green Thumb Farm.
The total set up cost is $6,839. Right now, we have an incredible opportunity to double our impact. The Johnson Ohana Foundation has generously pledged to match the first USD 2,500 we raise by 31st of December 2026.
Donate today and your gift works twice as hard to fund the system and divert 7.3 tonnes of local cafe waste from landfill every year.
Green Thumb Farm is a registered DGR charity, so donations are tax-deductible.

To show how organic waste becomes nutrient-rich compost — improving soil health, reducing landfill waste, and demonstrating how circular, sustainable systems work in practice.
Worms break down organic materials into rich, living compost that improves soil health — a natural process that reduces waste and supports productive, sustainable growing.
Yes — worm composting is woven into our school programs, farm tours, and community workshops, with practical techniques you can take home and apply in your own garden.
Fruit and vegetable scraps, coffee grounds, paper, and garden waste. We show exactly what works and how to manage a healthy, productive worm farm at home.
Worm castings improve soil structure, increase nutrient availability, and support beneficial microorganisms — a simple, powerful tool for anyone wanting to grow food sustainably.
It gives students and visitors a tangible example of circular resource use — turning food waste into something valuable and making sustainability feel real and achievable.
