For 11 years, the Sylvester Ray Construction company dumped demolition debris in its 27-acre landfill on Clay Pit Road in Marshfield. When the lot was closed in 1988, it took two years for the site to be capped with a layer of clay at least 18 inches thick, covered with topsoil. For 20 years, the site seemed destined to sit dormant in an industrial zone north of Wildcat Woodland.
Then in 2011, state officials granted the site a post-closure use permit, and at a ribbon cutting on Tuesday officials unveiled a 3.87 megawatt-capacity solar panel project, marking the Sylvester Ray site as the 16th operational renewable energy landfill project in the state.
Four other sites became operational in August and September of 2013, and Marshfield brings the grand total to 16.
