Waste Diversion

Mālama ʻĀina Compostables is redefining what youth-led waste diversion looks like — one cafeteria tray at a time. Through hands-on programs, innovative technology, and real employment, these students are transforming how Hawaiʻi Island thinks about food waste.

About this project

What began as a simple cafeteria sorting program has grown into one of the most impactful youth-led waste diversion initiatives on Hawaiʻi Island. At the launch of the REO grant, students from Mālama ʻĀina Compostables established a cafeteria waste diversion program at their school, stationing themselves at the lunch bins each day to educate and assist their fellow K–12 students in properly separating compostable materials from plastic and landfill waste. From day one, these students weren’t just learning about sustainability — they were doing the work.

In the early days of the program, all diverted food scraps were donated to a local pig farmer, keeping organic material out of the landfill and supporting the local agricultural community. Then, late in Year One, a grant awarded by the Stupski Foundation made it possible to take the program to the next level. The students acquired an in-vessel composting machine — which they named Ho’ohuli, meaning “to turn or to change” — a fitting name for a machine that transforms waste into something valuable. Ho’ohuli now processes food scraps alongside compostable serviceware generated in the cafeteria, including trays, cutlery, napkins, and cups, producing high-quality compost in the process. Students continue to divert some food to the local pig farmer while channeling the remainder into Ho’ohuli, maximizing diversion across every material stream.

Since its inception, the program has diverted over 30,000 pounds of food waste from the cafeteria alone — a milestone that speaks to the consistency, dedication, and skill of these young leaders. The compost produced by Ho’ohuli closes the loop, returning nutrients to the land rather than sending them to the landfill.

The impact of this program has extended well beyond the school campus. Mālama ʻĀina Compostables has become a recognized leader in waste diversion on Hawaiʻi Island, influencing the County of Hawaiʻi to explore expanding its composting infrastructure using this same state-of-the-art technology. Other schools across the island have taken notice and are now looking to replicate this model in their own cafeterias. The students have also deployed their diversion systems at community events around the islands, bringing their expertise beyond the school gates and demonstrating what youth-led Zero Waste operations can look like in real-world settings.

Key Highlights

  • Launched a cafeteria waste diversion program educating K–12 students on separating compostable, recyclable, and landfill materials daily
  • Diverted 30,000+ lbs of food waste from the cafeteria landfill stream since the program’s inception
  • Acquired Ho’ohuli, an in-vessel composting unit funded by the Stupski Foundation, now processing food scraps and compostable serviceware into high-quality compost
  • Partnered with a local pig farmer to divert additional food scraps and support the local agricultural community
  • Influenced county-level composting infrastructure expansion through demonstrated success of in-vessel composting technology
  • Replicated and exported the model to other schools across Hawaiʻi Island seeking cafeteria diversion solutions
  • Deployed diversion systems at community events across the islands as a hired youth-led operation
  • Employed as part-time Recycle Hawaiʻi staff, giving students meaningful paid work tied directly to their diversion efforts

From the Cafeteria to the Community

What makes this program extraordinary is not just the pounds diverted — it’s what the work has done for the students behind it. These young people have built real skills, earned real wages, and earned real recognition locally and beyond. Their cafeteria program has become a proving ground for what is possible when youth are trusted with responsibility and given the tools to lead. As Ho’ohuli continues to turn waste into compost, Mālama ʻĀina Compostables continues to turn students into sustainability leaders — changing the system from the inside out.

Everyone can help!

Support Mālama ʻĀina Compostables and help us expand youth-led waste diversion across Hawaiʻi.
