Our Composting Process
From Maui Green Waste to Healthy Local Soil
At Hawaii Organics Compost, we transform locally sourced green waste into high-quality compost and mulch products that support healthier landscapes, farms, and gardens across Maui. Our windrow composting process helps divert valuable material from the landfill while creating sustainable, locally made soil solutions for the community.
We take compost quality and safety seriously. Our process follows U.S. Composting Council standards and industry best practices to help ensure our products are clean, safe, and free of biosolids and food waste.

Green waste is processed and reduced into smaller material sizes to support efficient composting and mulch production.
This step helps:
-
Increase airflow

Speed up decomposition

Prepare material for composting
Step 4 — Composting
Nature Does the Work
Material is formed into compost rows and actively managed throughout the decomposition process. During composting:
-
Microorganisms break down matter
-
Temperatures naturally rise
-
Material is monitored, turned, and watered regularly
PFRP: Our composting process follows industry standards designed to kill pathogens and weed seeds through controlled high-heat composting.
