プロジェクト概要
The Dalton-Whitfield Landfill Project captures methane-rich landfill gas from the Old Dixie landfill in Dalton, Whitfield County, Georgia. The Dalton-Whitfield Regional Solid Waste Management Authority developed and operates this project to improve environmental and financial performance, rather than to meet a regulatory requirement. The system cleans the landfill gas and sends it to a nearby industrial boiler to replace natural gas. Any remaining gas is burned in an onsite candlestick flare to destroy methane.
The project reduces emissions by collecting landfill gas from a network of wells and combusting it. Combustion converts methane into carbon dioxide, which has a lower warming impact, and sending gas to an industrial boiler displaces fossil fuel use. The landfill has a permitted capacity of about 6.3 million tonnes, and the collection system currently pulls gas from dozens of wells across the site. The project began operating in 2008, with the flare and pipeline components commissioned that year.
The Authority owns the landfill and its gas collection and control system while managing day-to-day operations. Anew Environmental serves as the carbon credit manager and consultant. The project is not implemented due to a legal mandate; testing and regulatory review indicate the site is below thresholds that would otherwise require a gas collection and combustion system.
