Convertus Advanced Aeration Composting Facility

The Manassas facility was designed to minimize the region’s environmental footprint, while producing top-quality renewable resources in a safe and sustainable manner. Using cutting-edge aerated static pile technology, the facility processing times range from 60 to 75 days, a process that is 4-5X faster than windrow composting. Annually, 100,000 tonnes of green bin waste is converted into compost, mulch and soil amendments.
