Where Does Chattanooga's Trash Go? Landfill Explained

You fill a roll-off, the hauler picks it up, and it disappears down the road. Most people never think about what happens next. But where your debris actually ends up — and how it's weighed and priced when it gets there — has a direct effect on what you pay. Here's the real answer for Chattanooga.

Birchwood Landfill: the region's main destination

Most construction and demolition debris, household junk, and general waste collected by Chattanooga-area roll-off haulers ends up at the Birchwood Landfill in northern Hamilton County, off Highway 60 near the Tennessee River. It's one of the primary Class I disposal facilities serving Chattanooga, Hixson, Red Bank, Soddy-Daisy, and the surrounding Tennessee Valley communities. Some haulers route specific material — clean concrete, scrap metal, cardboard — to separate recycling or transfer facilities instead, but for a typical mixed-debris roll-off, Birchwood is where the truck is headed.

Why the landfill matters for your dumpster price

Every load that crosses the scale at a facility like Birchwood gets weighed coming in — full truck weight minus empty truck weight equals your debris tonnage. That number, not the volume of your container, is what haulers bill against.

This is why your rental agreement lists a tonnage allowance (typically 2–4 tons depending on container size) rather than just "one dumpster, one price." If your load weighs in under the allowance, you're done. If it's over, Chattanooga haulers typically charge an overage of about $0.04–$0.05 per pound, or roughly $75 per ton — because that's close to what the landfill charges the hauler for the extra weight in the first place. The fee isn't arbitrary; it's a pass-through of the actual tipping cost.

That's also why dense material catches people off guard. A 20-yard box packed with roofing shingles or wet plaster can hit its weight limit while still looking half-empty. Volume and weight are two different limits, and the scale at the landfill is the one that decides your final bill.

What can and can't go to a Class I landfill

Birchwood and facilities like it are permitted for general construction, demolition, and household waste — but not everything. Standard exclusions across Chattanooga haulers include:

• Paint, solvents, and other liquids
• Motor oil and fuel
• Propane tanks and pressurized cylinders
• Tires
• Batteries
• Asbestos-containing material
• Refrigerant-bearing appliances (fridges, window AC units)
• TVs and electronics
• Fluorescent bulbs
• Medical waste

These items need separate disposal through household hazardous waste collection, an appliance recycler, or an e-waste program — mixing them into a roll-off can get a load rejected at the scale, which delays your project and can trigger extra fees. If you're not sure whether something belongs in the box, ask before it goes in; see our FAQ for the full list of what's typically excluded.

Recycling and diversion: not everything gets buried

A lot of debris never reaches the landfill floor at all. Clean loads of concrete, brick, and asphalt are often routed to a separate recycling operation instead of general disposal — and because processed aggregate has resale value, haulers frequently pass along a lower rate for a clean, single-material load. The catch is the word "clean": mix drywall, wood, or trash into a concrete load and it typically gets reclassified (and repriced) as mixed C&D debris. If you know a job is producing straight concrete, brick, or dirt, say so when you request a quote — a dedicated heavy-debris container keeps that material sorted and can save real money.

Scrap metal is the other common diversion. Appliances, ductwork, rebar, and wiring often have separate scrap value, and some haulers will pull it before the load ever reaches Birchwood.

What this means for your rental

A few practical takeaways from how the disposal side actually works:

• Sort what you can. Even a rough separation — clean concrete in one pile, everything else in another — can change which container and rate you need.
• Ask about tonnage, not just size. A 10, 15, or 20-yard dumpster each carries a different weight allowance; match the size to your debris density, not just how much space it takes up.
• Storm and yard debris may price differently. Green waste sometimes qualifies for a lower disposal rate than mixed household junk, since it can be processed separately rather than landfilled whole.
• Location affects logistics. Jobs in Hixson, Soddy-Daisy, and the north side of Hamilton County are closer to Birchwood than jobs in East Ridge or Lookout Mountain, which can factor into hauler scheduling on tight-turnaround projects. Check our service areas for coverage near you.

None of this is stuff you need to figure out alone. When you request a quote, tell us what you're disposing of and roughly how much — our vetted local haulers already know how Birchwood and the other regional facilities price each material, and they'll size and quote your job accordingly instead of leaving you to guess.
