Rolling Out A Statewide Organics Ban
The largest generators of food scraps (>104 tons/year) must start separating them on July 1, 2014 if there is a permitted composting facility within 20 miles to receive them. Green Mountain Compost in Williston, Vermont, a municipally-funded operation, is permitted to take food scraps.

Vermont’s Act 148 makes state first in the nation to mandate residential food scraps recycling and pay-as-you-throw solid waste collection to incentivize diversion.
