Full Breakdown

Under R.I. Gen. Laws Section 23-18.9-17, the food-waste ban, a covered entity must separate and divert organic waste to an authorized composting or anaerobic-digestion facility if it generates at least 104 tons per year of organic waste and is located within 15 miles of such a facility with capacity. The threshold is lower for educational institutions (52 tons per year, and 30 tons per year from 2023). The law targets supermarkets, hospitals, and other large generators; residential generators are exempt. DEM enforces compliance, and backyard household composting remains unregulated.
