Turning everyday waste into real-world solutions. 

How the Green 4 Better System Works

1. Collect from the Community
We collect brown materials such as clean cardboard (like shipping boxes) and green materials such as unused, unopened expired food that would otherwise go to waste. These materials become the foundation of our compost system.

2. Compost & Create Energy
The collected materials are turned into compost. As the compost breaks down, it produces natural heat. This heat powers a low-temperature Stirling engine, which helps generate energy to run a small water pump for our garden.

3. Reuse Water & Grow Plants
We also collect leftover clean drinking water from students’ reusable bottles and store it for irrigation. Using compost-created organic soil and recycled water, we grow vegetables, herbs, fruits, and flowers.

4. Reuse & Give Back to the Community
We reuse biodegradable egg cartons as seed starters to grow young plants. Once the plants are ready, we give them to families, seniors, and community members in Walnut and Diamond Bar.
This helps reduce waste, supports sustainability, and makes it easy for everyone to be part of the solution.

5. A Full Community Cycle
This creates a continuous cycle:
Community Waste → Compost → Energy → Water → Plants → Giving Back

This model teaches sustainability, science, teamwork, and social responsibility all at once.
