Lahaina, HI - West Maui GreenCycle Compost Facility

Community Composting for Education and the Environment

West Maui GreenCycle was expanding its established composting operation to increase diversion from the landfill by working with local schools to compost their Source Separated Organics as part of their educational effort. West Maui GreenCycle, although an established facility, was concerned about being a good community neighbor and meeting environmental regulations as they expanded their operation. Selecting a compost system with the best available process control quickly became a very important factor in the expansion.
