Until further notice, no-cost residential food scrap drop-off  (limit 30 gallons) has been moved to CSWD’s Williston Drop-off center a half-mile down Redmond Road: Open Monday through Saturday 8am -3:30pm. 
Leaf/yard debris and commercial food scraps (>30 gallons) are still being accepted at the Green Mountain Compost facility and must be free of trash, plastic, dirt, rocks, metal, branches, lumber, or contamination of any kind.  

At Green Mountain Compost, we make compost on a large scale. Unlike most backyard compost piles, our compost is carefully formulated using a wide variety of inputs and even our smallest piles are huge weighing in at hundreds of tons of mixed ingredients per pile! We actively aerate our piles and frequently monitor them to maintain the ideal amounts of oxygen and moisture for the microbial web that drives the composting process. By achieving ideal conditions, our pile temperatures get really hot really quickly – sometimes within hours.

The high temperatures of our compost process allow us to accept many items that simply don’t work in a backyard compost pile. While you might want to think twice before adding meat, bones, or other potentially tasty treats for four legged critters to your backyard compost pile, these ingredients work great for our composting process. Other materials such as dirt, sod, and metal don’t work so well and are not acceptable in our compost.

Please Contact Us if you are unsure whether your item is compostable or if you have more than 30 gallons of compost to drop-off.
