Hawaii Students Turn 20,000 Pounds of Waste Into a Zero-Waste Revolution

A student-led zero-waste project at Ka'u High School has made a big impact since its launch in 2024. The initiative, called Malama 'Aina Compostables, has already kept over 20,000 pounds of waste from ending up in the West Hawaii landfill. Now, with a $1.5 million grant, the group is expanding its efforts in recycling, composting, and waste education. The project began last year with nine students working to reduce waste through education and hands-on action. They run events to collect recyclables and food scraps, turning them into compost. Their composting unit, named Ho'ouli, cost $35,000 and is built to last two decades. Each schoolday, it processes around 100 pounds of food waste, creating nutrient-rich soil.

At the 2025 Volcano Renaissance Faire, the students proved their approach works. With 2,500 attendees, they managed to divert 90% of the event's waste from the landfill. The group also plans to sell the composted soil, using the income to fund school programmes and support local farming. Waileia Kainoa, a senior at Ka'u High, has been part of the initiative from the start. The team's work comes at a critical time—building a new landfill on Hawaii Island would cost an estimated $500 million. Instead, their focus on recycling and composting offers a sustainable alternative.

The $1.5 million grant will help the students continue their zero-waste mission over the next three years. Their efforts have already cut landfill waste significantly while providing useful compost for the community. With ongoing projects and events, the group aims to keep growing its impact across Hawaii Island.
