A final resting place for construction and industrial debris is about to get bigger in Scott County.

Dem-Con Cos., a Shakopee-based provider of construction and demolition recycling and other waste management services, has paid $11.26 million in cash for a 100-acre landfill expansion site in Scott County, according to a certificate of real estate value made public Friday. The sale price breaks down to $112,640 per acre.

Located just west of Louisville Road and south of Dem-Con’s existing operation at 3601 130^th St. W. in Shakopee, the property is part of Dem-Con’s planned 241-acre landfill expansion in Louisville Township, a Scott County municipality near Shakopee.

Dem-Con Landfill LLC purchased the property from Bryan Rock Products. Scott County records show that Bryan Rock Products paid $4.7 million for the property in September 2010. Bryan Rock Products describes itself as a provider of limestone products for “contractors, government agencies, asphalt production and ready-mix concrete operations.”

The expansion area is an “active limestone quarry that is nearing completion and preparing for final reclamation activities and end use development,” according to the Minnesota Pollution Control Agency.

Finance & Commerce reached out to Dem-Con for comment.

In an environmental assessment worksheet published last year, Dem-Con said the expansion will allow the company to “continue to meet the recycling, C&D [construction and demolition] and industrial waste disposal needs of the community.”

“Despite continued improvement and investment in waste recycling and processing, local landfilling continues to be a necessary component of the overall integrated waste management system needed to serve Scott County and the Twin Cities metro area,” the company said in the EAW.

Kate Sedlacek, Scott County’s environmental services manager, said the expansion is strictly for demolition and industrial materials, not municipal household waste. A similar facility is located in Dakota County, but there’s “not a lot of demolition landfills in the metro,” she added.

“Although we keep striving to reach our recycling goals, we still have demand for landfills,” Sedlacek said.

The expansion, which has been in the works for years, cleared a number of regulatory hurdles in 2023.

In February, the Minnesota Pollution Control Agency ruled that the project “does not have the potential for significant environmental effects.”

Last spring, the Scott County Board approved an interim use permit for the project. Dem-Con is working with the county’s Environmental Services Department to amend its solid waste permit to add acreage to the south, Sedlacek said.

The MPCA permitted the existing landfill in November 1985 and Dem-Con began operating there in January 1986, the November 2022 EAW notes.

According to the EAW:

• Construction and demolition waste accounts for about 70% to 85% of material accepted at the site. The rest is industrial waste.
• The current landfill has an “ultimate design capacity” of 19 million cubic yards, with less than seven million cubic yards remaining. The expansion will add 36.25 million cubic yards of capacity.
• At present, the landfill accepts construction and demolition debris from the seven-county metropolitan area and beyond. Debris accepted at the site includes concrete, brick, untreated wood, masonry, plastic building parts and other materials generated from demolition, renovation, construction and road-building projects.
• Dem-Con hopes to begin the first phase of expansion in 2023. The expanded landfill will have an estimated remaining life of 55 to 60 years. Without the expansion, the estimated life is “less than 10 years.”
