Kingsbury entered into the renewable energy field in 2008, specifically constructing Landfill Methane Gas to Energy (LFMGTE) plants. The level of expertise and commitment to these types of projects allowed Kingsbury to be a part of the expansion of the only two operating landfills in the state of Vermont, as well as one in Northern New Hampshire. This expertise not only encompasses LFMGTE plant construction, but also HDPE fusion welded pipe, horizontal and vertical wells, and gas extraction networks.
