In 1996, an in-vessel pilot facility for composting food residuals opened on the island. Utilizing an IPS agitated bay technology with positive flow aeration controlled by a timer, the facility was designed to handle 10 tons/day of food residuals from on-site kitchens. The operation, under ORI's management as well, currently processes approximately 25 tons/day of food residuals collected from prison kitchens by Department of Sanitation trucks. Wood chips from recycled wood and tree parts are used for bulking agent, combined with food residuals at an approximate ratio of 2:1, depending on the mass balance.

City Government installed a 43.7 kW PV system in November 1996.
