Ranjiv Gupta and Jeremy Morris Present Geothermal RET Results in Kyoto

Ranjiv Gupta, PhD, and Jeremy Morris, PhD and PE — both of Geosyntec's Maryland office — presented an overview of issues related to geothermal heat and municipal waste landfills during a workshop held Oct. 7 in Kyoto, Japan.

The Second U.S.-Japan Geoenvironmental Engineering Workshop featured leading researchers in geoenvironmental engineering discussing challenges both countries face in the sustainable management of waste. The recurring workshop fosters an exchange of knowledge and ideas with the goal of developing collaborative projects among international attendees.

During the workshop, Ranjiv and Jeremy co-presented a paper based on their work at the Lorton Energy Park in Lorton, Virginia. The two examined the installation of four renewable energy technologies (RETs) at a municipal landfill in Lorton and produced a feasibility study evaluating the technical and financial feasibility, aesthetic qualities, and regulatory and public acceptability of each.

Their study determined that, once the landfill is closed and capped, it has the potential to support four RETs — solar, wind, biogas and geothermal technologies — with a total energy output in excess of 10 megawatts. Lorton Energy Park is notable in that it represents the first landfill to utilize the heat capacity of waste for geothermal energy. Once the energy park is operational, it will be the first closed landfill to feature four individual RETs running concurrently.

The results of this study were presented in Kyoto as part of a paper, "Issues in the Use of Municipal Waste Landfills as Geothermal Heat Sources."
