Feasibility Study for Waste-to-Energy Technologies
« All Projects

Robins Air Force Base, located in central Georgia, has goals of reducing the quantity of waste that is sent from the base to landfills, generating renewable energy on the base, and reducing environmental impacts of the base.

Geosyntec was retained by the base to conduct a Feasibility Study (FS) to evaluate currently available waste-to-energy (WTE) technologies that could potentially be utilized and to recommend technology based on the types and quantities of wastes generated on the base and potential to achieve the goals of the base.

Geosyntec's Scope of Services

Geosyntec conducted a feasibility study which consisted of identification of WTE technologies, a preliminary screening of identified WTE technologies, and a detailed evaluation of a selected WTE technology. Geosyntec evaluated the base waste streams and volumes as well as energy consumption and costs. Geosyntec also reviewed technical literature related to WTE technologies and conducted surveys of a few technology vendors. A preliminary screening of both thermal and bio-chemical WTE technologies was performed to identify the technologies that have the highest potential of meeting the base's goals, which resulted in selecting plasma gasification for a more detailed evaluation. The detailed evaluation included assessing the technical, regulatory, and economic feasibility of implementing plasma gasification at the base, as well as the development of a conceptual layout of a plasma gasification facility. For the economic feasibility analyses, Geosyntec considered several options that included different facility capacities in tons per day, importing of off-base waste, and private developer participation. The financial analyses considered capital costs, operation and maintenance costs, feedstock cost, waste disposal cost savings, value of net electricity, renewable energy credits, carbon emission reduction credits, value of recovered metal and slag, and tax credits.

Geosyntec concluded that the application of plasma gasification at the base is technically and economically feasible and should meet the base's goals. Geosyntec recommended a path forward for implementing this technology at the base including reviewing conceptual design details with technology vendors, discussing specific permitting requirements with the regulatory agencies, and soliciting detailed proposals from qualified vendors.

Notable Accomplishments

The WTE FS performed by Geosyntec provided the base with the technical, economic, and regulatory rationales for selecting plasma gasification as the most feasible technology for the base to reduce waste landfilling, generate renewable energy, and reduce environmental impacts. The FS also provided the base with specific recommendations for implementing plasma gasification at the base.
