The Current Prototype
Green 4 Better is currently exploring a small-scale household compost concept designed to encourage sustainable living at the everyday level.
The project focuses on how everyday organic materials, such as food scraps, leaves, and cardboard packaging, can be transformed into nutrient-rich compost that supports plant growth while reducing environmental waste.
As part of this exploration, students are studying how environmental factors influence the composting process and the development of young plants. The team collects observational data including temperature, moisture levels, and plant growth progress in order to better understand how small-scale compost environments function.
The project also includes comparing different composting conditions to observe how variations may affect decomposition efficiency and plant development. These observations help students learn how natural processes can be better understood and potentially applied in everyday household settings.
The goal of this research is to explore how simple resource cycles, such as composting organic waste and supporting small-scale plant growth, can contribute to more sustainable living practices within communities.
In addition to studying composting and plant growth, the project also explores how natural resources such as sunlight, compost-generated heat, and water reuse may support small-scale sustainable systems. The team is interested in understanding how these elements could be thoughtfully integrated into everyday household environments.
The project is currently in the early development stage, and the team continues to study and experiment with different approaches.
In the future, the team hopes the lessons learned from this exploration may help inspire simple sustainability ideas that families and communities can adopt in everyday life.

Early Concept Exploration (2025)
Early Concept Exploration (2025)
Before developing the current household-scale concept, the Green 4 Better team explored an earlier idea focused on the heat generated during composting. The concept investigated whether natural heat produced through composting could potentially be used as a small renewable energy source.
Although the idea remained in the exploration stage, the experience helped students learn about renewable energy, compost science, and engineering problem solving.
Although the idea remained in the exploration stage, the experience helped students learn about renewable energy, compost science, and engineering problem solving.
This early exploration eventually led the team to shift toward a simpler household-scale sustainability concept that may be more accessible for everyday communities.
How the Green 4 Better System Works
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.
