A large-scale organics management company entered into a contract to own and operate a new processing facility serving the local community. The new facility will be in northern Virginia and is expected to recycle more than 80,000 tons per year of yard waste, 7,500 tons per year of wood waste, and up to 100,000 tons per year of food and other organic wastes. The facility will create high-value compost, soil products, and non-synthetic fertilizers; up to 125,000,000 cubic feet of biogas per year; and sustainable locally-grown fruits and vegetables for sale back into the community. Current compost operations at the facility entail piling yard waste of leaves and grass into high, long rows and manually turning with the use of heavy equipment. The new facility is designed with an advanced aerobic composting technology where the leaves and grass are mixed and placed in large aerated bunkers.
Loureiro provided survey, civil, mechanical, and electrical engineering, with local and environmental permitting services as necessary, to integrate the various technologies, expand the required utilities, and design a phasing plan to facilitate continued operations during the construction of the new operations. Our services involved collaboration of the various technology partners to integrate the equipment and assess the management of storm and wastewaters and to ascertain the final disposition of the biogas generated by the Anaerobic Digester. Loureiro initiated the project programming, conceptual design, design development and construction document phases, and designed the leachate and stormwater management and reuse/treatment facilities. Loureiro also prepared all of the state and local permitting for the facility, including permits by rule, individual permits, and land-use permits for the new operations through the Virginia Department of Environmental Quality, and the county.
These state-of-the-art waste processing approaches will double the throughput capacity of waste materials at the facility; provide new technologies for advanced composting of yard waste and anaerobic digestion of food waste; generate biogas as an alternative energy source; and support fruit and vegetable cultivation with year-round greenhouse operations. The advanced composting process will dramatically reduce the time required to generate valuable compost, from the current timeframe of six to nine months, to just within 40 to 45 days. The added benefits of biogas generation provide a long-term sustainable energy source that the community can be proud to source.
