Olmsted County's Kalmar Landfill is located between Rochester and Byron at 7401 19th Street NW, Rochester, Minnesota. The natural geology below the Kalmar site provides an ideal location for a landfill. 

Three types of cells have been constructed to contain waste primarily from licensed or registered haulers:

  1. Mixed Municipal Solid Waste (MMSW) Cell - consists of four feet of compacted clay, topped with a 60 mil. high density polyethylene plastic liner, and a leachate collection system. This cell was constructed to contain commercial and residential garbage transferred or "by-passed" to the landfill when the Olmsted Waste-to-Energy Facility (OWEF) is performing scheduled maintenance, experiencing garbage overruns, or receives MMSW that cannot be processed at the OWEF. MMSW from residences must be taken to the Olmsted County Recycling Center Plus located at 305 Silver Creek Road NE in Rochester. 

  2. Ash - Consists of a 3 foot compacted clay barrier layer, a 60 mil. high density polyethylene (HDPE) plastic liner, an additional 2.5 foot compacted clay barrier layer, another 60 mil. HDPE liner and a leachate collection system on top of the existing natural clay. Only ash from the combustion resulting from the OWEF operations, ash from the Mayo medical waste incinerator, and coal ash from the local utility are accepted.

  3. Construction and Demolition Debris Cell - Constructed utilizing the existing clay on the site as a natural barrier. Only construction and demolition materials from buildings, roads, and other man-made structures including concrete, brick, bituminous, untreated wood, masonry, glass, rock, and plastic building parts are accepted. Asbestos cannot be disposed with demolition materials, please see information on Asbestos (470 KB) wastes.


*Please Note - All loads being delivered to the landfill must be covered and contained.  Any person determined to be responsible for debris or liquids on the road rights-of-way shall be liable for the costs of removal thereof.

Tires - Special Handling Fee

Large quantities of tires are subject to a special handling fee of $50.00 per 1,000 lbs. of tires, to offset extra processing (shredding and hauling). This is in addition to applicable disposal fees. 

Household quantities of tires (8 or fewer per load) can be taken to the Olmsted County Recycling Center Plus for a fee (160 KB).


Cover and Secure Loads

A fee of $20 will be charged to unsecured/uncovered loads. For more information, see  the Covered Loads Brochure. (161 KB)
