LOWELL, MASS. – April 14, 2015 – TRC Companies, Inc. along with its client Waupaca Foundry, Inc. (WFI), announced today that they have won an American Council of Engineering Companies (ACEC) Engineering Excellence Award in the State of Wisconsin as well as a National ACEC Engineering Excellence Recognition Award for their project which promotes the re-use of by-products to enhance the sustainability of WFI’s landfill.
“TRC is proud to be recognized for our work with Waupaca Foundry,” said Doug Genthe, Managing Principal of TRC’s Solid Waste Management and Geotechnical Engineering Practice. “This innovative approach to landfill construction is a great example of engineering and environmental consultants working together with industry to apply new technical approaches that deliver sustainable solutions.”
WFI owns and operates a non-hazardous waste disposal facility near Waupaca, Wisconsin, that receives sand and slag by-products from three nearby WFI foundries. WFI teamed with TRC to determine if it could re-use the foundries’ by-products in the construction of final cover and liner barrier layers for its landfill.
In 2011, TRC and WFI constructed test pads with underlying collection systems to assess the long-term performance of beneficially re-using sand and slag by-product as a landfill liner barrier layer material. The test pads were monitored for over two years and exposed to two full cycles of Wisconsin weather.
Following the successful performance of the test pads, in May 2014, the Wisconsin Department of Natural Resources approved a plan modification to WFI’s landfill permit to allow the use of the sand and slag by-product material as a liner barrier layer in the landfill. As a result WFI will reduce landfill construction costs, extend the life of their landfill, reduce the landfill’s environmental impact and improve the sustainability of its operations.
According to Waupaca Foundry environmental coordinator Bryant Esch, Waupaca Foundry has successfully pursued beneficial reuse of its sand byproduct for over two decades. "A continuous improvement goal has been to identify and facilitate increasingly value added uses for these materials,” Esch said. “Waupaca recognized the potential of spent foundry sands as a native clay replacement for low permeability barrier construction projects, and with our TRC project partners, we collectively achieved the completion of an exciting project that represents real and substantial environmental improvement,” he said.
Through the re-use of the sand and slag by-product, 80,000 cubic yards of waste material for the liner barrier layer and 112,000 cubic yards for the final cover barrier layer that would have been destined for disposal in the landfill has been eliminated. WFI anticipates construction of the new liner barrier layer system during the summer/fall of 2016.
