Kauai's First Curbside Food Compost Pick-Up Service

our Services & pRODUCTS

We are community composters and we believe in a decentralized system...

Rather than sending our trash to be the burden on one community, such as Kekaha, we envision a system where we each take responsibility for our waste. A decentralized system with households, farms and local community composters processing food waste and organics can reduce the traffic, cost and environmental burden that typically follows a large-scale centralized waste system.

We remember to recycle our glass, plastic and aluminum, so why not our food?

As an island with finite resources, composting has an endless list of benefits for a sustainable island community. From diverting materials from the landfill to the application of finished compost to improve soil health, compost is the first and final step to connecting our food system and community.

How it works

Our Values & mission


Compost Kauai began with three friends who were really into creating something good for their community. 


A 2016 waste characterization study done by the County of Kauai shows that approximately 25% of waste entering the landfill is compostable. This includes paper, food waste and other organics. Compostable materials are an extremely valuable resource for an island with finite resources. We believe they should have an opportunity to be returned back to the soil, not lie waste in a landfill tomb.


Knowing that our only landfill is projected to reach capacity in 2026, our current food-system is heavily reliant on imported goods, and residents express difficulty in composting on their own, we wanted to provide a service to alleviate these issues.

In 2020, in the midst of a pandemic, Compost Kauai came to fruition.


Compost Kauai provides services that make it easier for the community to close the food system loop and support truly local recycling on island. We support everything from individual residents to large scale events.


Our mission is to collect food scraps and other local compostables to divert them from our island’s overwhelmed landfill and transform them into nutrient-rich compost, which can then be used to grow more food.


To achieve our mission,

  • we recognize food scraps as a resource which previously required other valuable resources in its cultivation and transportation (water, fertilizer, fuel, labor),

  • we partner with like-minded community members, who don't have enough food scraps for the pig farmers but might have more than they can handle themselves,

  • we make the effort to close the loop by diverting and converting local organic materials into a soil amendment that can further benefit our community and island.

We understand that a sustainable island food system is not only a community of those who produce, process, distribute, and consume local foods, but also involves recycling and returning valuable nutrients back to the soil. Our community's actions can enhance Kauai’s environmental, economic and social health as well as build community resilience.

Contaminated compost is our greatest challenge for healthy soils.

"Everyone who lives on Kauai should compost. Compost Kauai makes it easy to do some good for our island environment. It's a forward thinking business model that I hope spreads island-wide. The communication and customer service are great as well. I support their mission and appreciate their hard work."
"We always wanted to compost and Compost Kauai offering weekly curbside pickup made it an easy decision. We have an odor-proof small bucket we keep next to our sink and transfer it to the larger Compost Kauai bucket we keep outside. Composting has changed the way we eat and shop for food. We now eat healthier, less processed food, and eat more local food from farmers markets. Compost Kauai employees have always been very friendly when picking up buckets, making minimal noise, and the communication has been great. We continue to tell other people about Compost Kauai and hope they can expand their service island wide!"
"I love composting with Compost Kauai. My wife was worried about smell, roaches and rats with a black bin. With the compost Kaua’i system we don’t have to worry about any of those issues. Instead we keep our food waste out of the landfill and get compost for our garden."
