County Rules

Your Load Does Not Go to a Landfill. It Goes to a Furnace.

The question here is not whether a hole in the ground will take it. It is whether it burns, and whether it fits through the door.

A different question entirely

In most of the country, the question about a dumpster load is whether a landfill will accept it. Around here that is the wrong question.

That one difference changes a surprising amount. Material that is perfectly acceptable in a landfill two states away is a problem here, and the reasons are mechanical rather than regulatory.

It also means something else, covered properly in our article on where waste is allowed to go: your load cannot simply be driven somewhere cheaper. Waste that starts in Olmsted County stays in Olmsted County's system.

⭐ The size rule nobody tells you

This is the single most useful fact on this page, and almost nobody mentions it.

Think about what that actually rules out of an ordinary clear-out:

• A full-size sofa. Comfortably over five feet.
• A dining table, assembled.
• Long dimensional timber — studs, joists, deck boards, fence rails.
• Rolled carpet, unless it is cut down.
• Mattresses, which are both long and awkward.
• Doors, sheets of plywood, countertops, full lengths of trim.
• Bed frames, wardrobes, large shelving units left whole.

None of that is banned in principle. It simply has to be broken down so it meets the sizing requirement, or routed somewhere else.

The practical consequence is one most people never hear: cutting things down is not just about fitting more in the container. It is about the load being accepted at the other end. A sofa cut into three pieces is a different proposition from a sofa.

Tell us what the big items are when you book, and we will tell you which need breaking down and which we will route separately.

What burns well

The ordinary mixed waste of a household or a renovation, once the problem streams are out of it:

• General household contents — the broken, the worn out, the unsellable
• Packaging and non-recyclable paper and card
• Textiles and soft furnishings, broken down to size
• Treated and painted timber, cut to length
• Carpet and underlay, cut down rather than rolled whole
• Most plastics that are not recyclable
• Insulation and similar light construction waste

It is a forgiving list. The constraints are size and the specific exclusions below, not some long schedule of prohibited materials.

⚠️ What the furnace will not take

Beyond the size rule, four categories are excluded outright:

Recyclables

Not because they would not burn, but because Minnesota requires it. If material has been separated for recycling, it must be recycled — a hauler may not dispose of it and a disposal facility may not accept it. That is state law, not local preference.

Appliances

Major appliances are banned from landfill in Minnesota and are not accepted at the waste-to-energy facility either. They are largely metal, they do not burn, and they damage equipment. Washers, dryers, refrigerators, freezers, stoves, water heaters, air conditioners — all of them have their own route.

Electronics

Televisions and other video display devices are banned from Minnesota landfills by statute, and electronics are excluded from the furnace as well. Computers, monitors, TVs: separate route.

Un-vented tanks and pressure vessels

Anything sealed that could contain pressure or residual fuel. This is a genuine safety exclusion — propane cylinders, compressed gas bottles, un-purged fuel tanks. A sealed vessel in a furnace is a serious incident, not an inconvenience.

⚠️ And the obvious one, which applies everywhere: asbestos never goes in a container, in any quantity, under any circumstances.

Where the rest of it goes

The county runs a complete chain, and each part has a job:

• The waste-to-energy facility — mixed waste that meets the size rule.
• Kalmar Landfill — construction and demolition material from buildings, roads and other structures: concrete, brick, bituminous, untreated wood, masonry, glass, rock, plastic building parts. It also holds a lined cell for mixed waste when the furnace is down for maintenance, and an ash monofill.
• Recycling Center Plus, 305 Energy Parkway NE — Tuesday to Saturday, 8:00 a.m. to 4:30 p.m. Free if pre-sorted: aluminum cans, glass bottles and jars, clean cardboard, paper, plastics #1, #2 and #5, tin and steel cans, and clean scrap iron, aluminum, copper, brass and stainless. For a fee in household quantities: appliances, bikes, carpeting, computers, construction and demolition material, drywall, furniture, garbage, grills, lawnmowers emptied of fluids, mattresses, TVs and automotive tires.
• The Hazardous Waste Facility, same address — free to residents. Paint, solvents, cleaners, pesticides, automotive and rechargeable batteries, sharps.

⚠️ Two specific limits worth knowing: mattresses and automotive tires are accepted eight or fewer per day at the Recycling Center, and the Hazardous Waste Facility will not take lithium-based batteries above 300 watt-hours.

⚠️ Why a banned item costs you money

Unauthorized material arriving at a county facility is subject to special handling fees. It has to be pulled out, routed correctly and dealt with separately, and that work gets charged.

There is also a rule people find surprising: haulers are not permitted to scavenge. Once material is tipped on the floor or out of a container it belongs to the facility. So nobody is going to quietly retrieve the appliance you buried under the drywall — it will simply be found, handled and billed.

⚠️ And one genuine safety point rather than a cost one: lithium-ion batteries have caused a fire at a county recycling facility. The batteries in phones, laptops, power tools, e-bikes and cordless everything are a real ignition risk in a loaded container, in a truck and on a tipping floor. They go to the Hazardous Waste Facility, free, and it takes five minutes.

What this means for sorting

Practically, a Rochester load sorts into five piles rather than two:

1. Burns and fits — into the container.
2. Burns but is too big — break it down, then into the container.
3. Construction and demolition material — concrete, masonry, untreated timber. Keep it separate; it has its own route and it is the heaviest thing you have.
4. Metal, appliances and electronics — out. Metal has real value, and all three are excluded anyway.
5. Hazardous and batteries — the Hazardous Waste Facility, free.

That sounds like more work than it is. For most jobs it is twenty minutes with a reciprocating saw and a couple of extra piles.

A short checklist before you load

• Measure the big things. Over 3x3x3 or over five feet long means breaking down
• Cut timber, carpet and furniture down to size
• Pull every appliance — banned from landfill and excluded from the furnace
• Pull every television, monitor and computer
• Pull the metal — excluded, and worth money
• Separate clean masonry and concrete — a different facility entirely
• ⚠️ Every battery out, lithium especially
• No sealed tanks or cylinders, ever
• Yard waste separately — banned from landfill statewide
• Tell us the awkward items at the quote, not at collection
