Ground Loop: A Circular Revolution for Coffee Waste
Year 1 (2025-26)
by Genesis Erhabor
Transforming spent coffee grounds into high-value sustainable products. From nutrient-rich fertilizers and exfoliating skincare to vibrant natural dyes, we unlock the hidden potential of every brew.
About This Idea
We are developing a smart, dual-purpose extraction and conversion system designed to transform organic waste (specifically spent coffee grounds) into high-quality raw materials. This versatile device is engineered in two scales: a compact, sleek version for household use and a high-capacity industrial model for cafes and corporations. It automates the process of drying, refining, and mixing grounds to create nutrient-dense fertilizer and premium skincare bases at the touch of a button.
Where Did This Idea Spark at WMU?
At my core, I am a builder. Whether I am writing a book, producing a beat, or designing for my clothing brand, Understanding Simple, my goal has always been to create something of value where nothing existed before.
The idea for this venture sparked at Western Michigan University, specifically within the Bronco Challenge for Sustainable Impact. After seeing the sheer volume of waste generated at the Valley Dining Center and campus Starbucks, my friends and I realized that 'waste' is simply a resource waiting for the right system.
Drawing on my background in Engineering Management, I am moving beyond just an idea to build a tangible solution: a dual-purpose conversion device. We are creating a bridge between the industrial and the personal, allowing businesses and individuals to transform coffee grounds into high-value fertilizer and skincare. For me, this isn't just a project, it’s the next evolution of my entrepreneurial journey, turning a 'just for fun' concept into an investment.
Impact in Kalamazoo
When this project takes off in The Zoo, the impact isn't just "green" it’s economic and community-driven. Because Kalamazoo has a specific culture of local gardening and a city government currently pushing a "Green Circular Economy" as part of its 2025-2035 Strategic Vision, our device solves problems for very specific groups.
WMU Dining (Valley Center) and the campus Starbucks win by drastically lowering their waste disposal costs.
Kalamazoo has a massive urban farming movement. Organizations like Tay’s Farm in the Edison neighborhood and Project Grow need high-quality, low-cost compost and fertilizer to feed the community.
The city is currently struggling with the rising costs of landfill disposal and methane emissions (which is 86x more potent than CO2).
The Zoo wins because we’re keeping the value (and the nutrients) right here at home.
How Investment Helps
Investment is the catalyst that transforms our engineering prototype into a certified, scalable Kalamazoo infrastructure. Funding allows us to bridge the gap from a student-led 'concept' to a legally compliant operation by securing UL certifications for our hardware and MDARD safety testing for our fertilizers, essential steps for any business to move from the dorm room to the Kalamazoo Farmers Market. Beyond the technology, this capital empowers us to hit our first local milestone: a 'Full-Circle Campus Pilot.' We will deploy our industrial units to capture and process 500 pounds of waste from WMU’s Valley Dining Center, delivering the first batches of 'Bronco-Gold' fertilizer to urban farms in the Edison and Northside neighborhoods. With this investment, we aren't just buying machinery; we are buying the speed and legitimacy required to become a cornerstone of Kalamazoo’s 2026 circular economy.
What I'll Do With the Money
To secure a foothold in Kalamazoo’s emerging circular economy, we have strategically allocated 100% of the seed budget across four critical pillars of growth.
First, (about 40%) is dedicated to R&D and Prototyping to transition our design into a UL-compliant, automated v2 unit.
We are allocating (about 25%) for Certification and Testing, ensuring our fertilizer and skincare bases meet MDARD and lab-safety standards for retail at the Kalamazoo Farmers Market.
To prove the model, (20%) will fund Pilot Operations, covering the logistics of our "Campus-to-Neighborhood" loop between WMU Dining and local urban farms.
Finally, (15%) will be used for Legal and Branding to establish our B-Corp status and protect our intellectual property. This targeted investment ensures that within six months, we move from a student concept to a legitimate, market-ready hardware solution for the city.
About the Founder
I am a builder at the intersection of engineering and storytelling. As an Engineering Management major at Western Michigan University, I specialize in optimizing complex systems.
Why me? Because I don't just "have ideas", I execute them.
Why now? Because I have just closed the chapter on that two-year book project, and I am funneling that same relentless focus into this venture. With the Bronco Challenge highlighting a massive waste problem at the Valley Dining Center, the timing is perfect.
