City of Longmont Waste Diversion Center at 140 Martin St, Longmont, CO 80501
The City of Longmont Waste Diversion Center is a municipal auto salvage and scrap metal facility at 140 Martin St in Longmont. It’s a self-service yard where residents and businesses can get rid of old vehicles, pull usable auto parts, and recycle scrap metal.
The center takes end-of-life vehicles, broken car parts, and other scrap metal for proper disposal or reuse. Unlike private junkyards, this is a city-run operation focused on waste reduction and recycling. Visitors can search for parts, drop off scrap metal, or surrender old vehicles for recycling. The yard doesn’t sell parts but lets you take what you need from vehicles marked for disposal.
Services & What to Expect
The Waste Diversion Center offers several key services for vehicle owners and scrap metal recyclers.
Vehicle Disposal & Recycling
The center takes non-running vehicles for recycling. Owners can drop off old cars, trucks, or SUVs that no longer run. The city processes these vehicles for scrap metal recovery and ensures fluids and hazardous materials are disposed of properly. There’s no fee for dropping off a vehicle, but you’ll need proof of ownership, like a title or registration.
Self-Service Auto Salvage
Visitors can browse the yard for reusable auto parts from vehicles marked for disposal. Common finds include engines, transmissions, doors, bumpers, and interior components. The center doesn’t keep an inventory, so what’s available depends on recent drop-offs. Bring your own tools—none are provided—and wear safety gear like gloves and eye protection.
Scrap Metal Recycling
The facility accepts scrap metal from vehicles, appliances, and other sources. Metal is sorted, processed, and recycled. Common accepted items include:
- Car bodies and frames
- Engines and transmissions
- Metal bumpers and trim
- Appliance shells (refrigerators, washers, dryers)
- Miscellaneous scrap metal (no electronics or hazardous waste)
Tires, batteries, and fluids must be disposed of separately.
Hazardous Waste Handling
The center follows strict rules for handling automotive hazardous waste, including:
- Motor oil and transmission fluid
- Lead-acid car batteries
- Brake fluid and antifreeze
- Air conditioning refrigerants
These materials are collected separately and recycled or disposed of according to environmental rules. Don’t mix hazardous waste with scrap metal.
