Recover the grounds. Regenerate the earth.

At Hidden Leaf Foundation, we’re doing more than collecting spent coffee grounds — we’re growing our community and giving back to the earth in the process.

Founded on the belief that communities should restore rather than deplete, Hidden Leaf began as a vision to reimagine the role of agriculture in sustainability. We created Hidden Leaf Farm as a living, breathing example of what regenerative agriculture can look like when it’s powered by intention, community, and innovation.

The farm serves as our hands-on laboratory — a space where we test sustainable growing methods, pilot soil-health initiatives, and demonstrate circular systems in action. From composting with spent coffee grounds to producing biochar and harnessing renewable energy, Hidden Leaf Farm shows what’s possible when we work with nature, not against it.

The foundation extends that mission beyond our fields. It’s the outreach arm that connects with local partners, businesses, universities, and volunteers to transform regenerative practices into scalable, community-wide impact. Through the foundation, we recover and repurpose organic materials, facilitate research collaborations, and educate the next generation of growers and environmental stewards.

We’re not a massive operation with endless rows of monocrops — we’re small, strategic, and sustainable by design. Every decision, from how we amend our soil to how we partner with others, is rooted in a single purpose: to give back more than we take.

Grew on the farm. Built on the foundation.
Hidden Leaf is proof that sustainability doesn’t have to be theoretical — it can be tangible, local, and life-giving. What begins on the farm ripples outward through the foundation, creating a regenerative model others can learn from, replicate, and grow within their own communities.

Our Mission: A New Standard for Organic Waste Recovery

Hidden Leaf Foundation is a 501(c)(3) nonprofit coalition dedicated to recovering spent coffee grounds (SCG) from Starbucks. Transforming waste into regenerative soil inputs, bio-energy, and community resilience. We partner with businesses, universities, and local farms to build a closed-loop ecosystem that diverts organic waste from landfills and returns nutrients to the land.

How it Works:

Step 1: Collection
Our process begins with connection. We partner with local cafés, roasteries, and businesses to collect spent coffee grounds (SCG), cardboard, and other organic byproducts — materials that would otherwise end up in the landfill. Each pickup is timed to your needs, ensuring a smooth process that’s simple and sustainable for everyone involved.

Step 2: Processing
Once collected, the materials are carefully stored and stabilized at our processing sites. From there, they are distributed to composting facilities, regenerative farms, research labs, and businesses that integrate SCG into their production cycles. This step closes the gap between waste generation and circular reuse — creating a reliable supply chain for sustainable inputs.

Step 3: Regeneration
Through innovative composting and bioenergy practices, these materials are transformed into nutrient-rich soil amendments, biochar, and research-grade biomass. Each batch contributes to restoring soil health, reducing emissions, and building community resilience — proving that what we throw away can, in fact, help everything grow.
