Dem-Con, a Minnesota-based waste operator, plans to convert part of its permitted construction and demolition (C&D) landfill space to hold municipal solid waste (MSW), according to regulatory filings reviewed by Waste Dive.

The conversion would reclassify permitted airspace at an existing Dem-Con facility, letting the operator accept putrescible waste streams rather than only inert debris. Permit reclassifications of this kind typically require a major amendment from the Minnesota Pollution Control Agency, the state regulator that issues landfill construction and operating permits.

Dem-Con already runs C&D processing and disposal capacity in Minnesota and has used its sites to handle demolition debris from projects across the Twin Cities metro area. Re-rating that airspace for MSW expands the customer base the operator can serve but pulls the site into a stricter monitoring, liner and landfill-gas regime.

Why are Rumpke's Kentucky odor complaints escalating?

Residents near Rumpke's Kentucky landfill continue to log odor complaints, according to the regional roundup published by Waste Dive. Documented complaints near landfills typically trigger consent orders from the Kentucky Department for Environmental Protection, odor-control retrofits or revised waste-delivery scheduling at the gate.

Rumpke, one of the largest privately held haulers in the Midwest, has not yet announced a corrective timeline in the current reporting window. Persistent residential complaints also weigh against an operator at permit-renewal and vertical-expansion hearings.

Which other states moved on landfill capacity?

The broader regulatory roundup flagged landfill activity in three additional jurisdictions:

• Hawaii – landfill updates pending disclosure of permit action
• Mississippi – landfill updates pending disclosure of permit action
• Michigan – landfill updates pending disclosure of permit action

What changes if Minnesota approves the Dem-Con amendment?

A major amendment would authorize the site to receive household and commercial putrescible waste under MSW handling conditions, including daily cover, leachate management and landfill-gas capture obligations that currently do not apply to its inert C&D cells. The decision sets the boundary on what volumes and waste types Dem-Con may accept going forward.

What milestones decide what happens next?

The next events to track:

• Minnesota Pollution Control Agency decision on the Dem-Con major amendment
• Any formal Kentucky DEP response on the Rumpke odor-complaint record
• New landfill permit actions posted by Hawaii, Mississippi and Michigan regulators

Each filing shifts available in-state disposal capacity and resets the gate-rate competition that local transfer stations, haulers and materials-recovery facilities face.
