Transforming organic waste into regenerative compost on Hawai‘i Island

Our Focus

Kona Soil Co. specializes in diversion of organic waste streams from landfills to to be transformed into nutritionally balanced, biologically diverse, and lab tested soil amendments. Our unique products are made specifically for use by gardeners, farmers, and landscapers in the Kailua-Kona area of Hawaii Island (the Big Island). Our soil amendments produce healthy plant growth and increased water/mineral utilization, resulting in balanced nutrient density in the crops/food. We hope to facilitate the development of healthy local environmental and economic systems, where nutrition begins with the state of a community’s soil. We serve mainly areas on the west side of Hawaii Island including: Kailua-Kona, Waikoloa, Keauhou, Holualoa, Captain Cook, Honaunau, Milolii, Hawaii Ocean View, Naalehu, and Kau district.

Rooted in Regeneration

Kona Soil Co. is a regenerative composting company. We specialize in turning local organic waste into living soil through methods that honor natural systems. Guided by balance, biology, and circular resource use, we work to rebuild our island’s soil health while reducing landfill impact and supporting local food security.

Our founder, Aaron Sloan, brings years of hands-on experience in compost production and soil science — and a lifelong love of working with the land. We believe that healing the soil is the first step toward healing ourselves and our ecosystems.

OUR MISSION

Compost with Purpose

At Kona Soil Co., we don’t see waste — we see potential. Every banana peel, tree trimming, and bag of kitchen scraps has a role to play in restoring the health of our ʻāina.

We believe nature already offers the blueprint for balance. Our work follows that wisdom: turning decomposition into regeneration, waste into nourishment, rubbish into richness.

When we build living soil, we support:

• Healthier crops with higher nutritional value
• Cleaner water through better infiltration and filtration
• More resilient ecosystems above and below ground
• Less waste in our landfills and ocean

We’re committed to helping Hawai‘i Island thrive — one handful of compost at a time.
