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 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 it expanded its operation. Selecting a compost system with the best available process control quickly became a very important factor in the expansion.
