By Ella Shih, Founder of Green 4 Better
Looking back, the vision I had when I first started Green 4 Better felt almost like a sci-fi movie. I wanted everything, a massive community system, renewable energy, and a perfect world.
It all truly started on Earth Day 2025. I happened to meet Mr. John Craig, and he invited me to bring my team from the Suzanne Middle School Chinese American Student Alliance (CASA), where I serve as President, to help with a composting project. There, I was personally captivated by the "mysterious heat" coming off the compost piles. I kept asking myself: If nature is already making this energy for free, why aren't we doing anything with it?
Our team initially designed an ambitious blueprint. We envisioned collecting food waste and cardboard from the community, using the heat from a large-scale compost reactor to power a Stirling Engine. We even dreamed of using leftover drinking water from school to irrigate fresh vegetables, which we would then return to the residents.
However, as we tried to make this "large-scale system" a reality, we hit some major roadblocks. We realized that finding a suitable site for massive compost piles was nearly impossible. More importantly, we discovered a serious safety risk: the extreme internal temperatures of large-scale compost can lead to spontaneous combustion. This poses a fire hazard that is simply unacceptable in a school or a dense residential neighborhood.
To find a way forward, we visited a local resident in Walnut. While his success was inspiring, it also gave us a reality check, that most families don't have the space for a massive setup, and they definitely don't want the smell or the fruit flies.
That was my turning point. I realized that if I wanted my community to actually participate, the system had to be safer, smaller, and much simpler. That is why I founded Green 4 Better. I wanted to take those big, high-risk industrial ideas and miniaturize them into something that truly fits into everyday family life.
Through countless failed sketches, safety tests, and long days of hard work with my team, we finally created the MCS-1. We moved away from trying to build a massive, risky machine. Instead, we are focused on letting every bit of energy complete its own cycle of life, safely and gently, in the corner of every home.
To empower the next generation of environmental leaders by transforming complex sustainability concepts into safe, practical, and accessible solutions for every household and community.
The students at Green 4 Better are not only working on their own research but are also actively engaging with local organizations to promote sustainable practices. By collaborating with community partners and public agencies, we gain real-world experience while sharing ideas that encourage responsible resource use.
Our recent initiatives include:
