Roll-Off Dumpsters in Port Orchard, WA: Sizes, Permits, and What You Can Throw In

Ferrous vs. Non-Ferrous Metals: Why the Difference Matters

Most scrap yards separate metals into two categories. Ferrous metals contain iron, making them magnetic and prone to rusting. Common examples include steel beams, car parts, cast iron cookware, and old appliances. Non-ferrous metals do not contain iron, so they resist corrosion and typically bring higher payouts because they are rarer.

A quick home test: hold a magnet to the metal. If it sticks, you likely have a ferrous material. If it does not, you may be dealing with aluminum, copper, brass, or another non-ferrous metal worth more per pound.

What Scrap Metals Can You Recycle?

Ferrous Metals Commonly Accepted

• Steel in any form, including sheet metal, pipes, and structural beams.
• Cast iron such as old cookware, engine blocks, and radiators.
• Scrap iron from appliances, farm equipment, and construction debris.
• Auto bodies and car frames with fluids drained.

Non-Ferrous Metals Commonly Accepted

• Copper, including bare wire, insulated wire, plumbing pipe, and fittings.
• Aluminum, including cans, gutters, siding, rims, and radiators.
• Brass, including pipe fittings, valves, and decorative items.
• Stainless steel, including cookware, containers, and tools.
• Lead, including wheel weights and old plumbing materials.
• Zinc, tin, and other specialty metals depending on the facility.

Electric motors, computer boards, laptops, and flat-screen monitors may also be accepted at facilities equipped to handle e-scrap and mixed metal items. Visit the scrap metal recycling page to see a full list of what American Northwest Recycling accepts.

Where Does Tacoma's Scrap Metal Come From?

Household Sources

Tacoma homeowners commonly encounter recyclable metal when clearing out garages, sheds, or upgrading appliances. Typical sources include old refrigerators, washers, dryers, and stoves; aluminum window frames, gutters, and siding from renovations; copper plumbing pipes replaced during remodels; and aluminum cans collected in bags or bins.

Commercial and Industrial Sources

Tacoma's active port, manufacturing base, and ongoing construction in areas like the Tideflats and SR-509 corridor generate significant scrap volumes. Commercial sources often include rebar, ductwork, and structural steel from demolition; copper wiring from electrical and HVAC work; aluminum and steel framing from build-outs; and industrial equipment and motors from fabrication shops. For large loads, roll-off container services can simplify bulk collection so contractors avoid multiple trips, which makes scrap metal recycling for Tacoma, WA, job sites practical even on tight timelines. Contact the team to ask about container availability for your job site.

How to Prepare Your Scrap Before Drop-Off

Sorting and Cleaning Tips

• Separate ferrous from non-ferrous metals before you arrive.
• Remove non-metal attachments such as plastic handles, rubber gaskets, or wood pieces when possible.
• Drain any fluids from motors, engines, or appliances before transport.
• Keep aluminum cans bagged or binned for easier processing, and do not crush them.
•  Most facilities accept items that are at least 80% metal, so mixed materials may need prep work before they qualify.

What You Should Not Bring

Hazardous materials, radioactive metals, and items containing harmful chemicals are generally not accepted. When in doubt, call (360) 813-3535 to confirm what American Northwest Recycling will take before making the trip.

Pierce County Recycling Context for Tacoma Residents

Pierce County maintains a recycling resource guide listing metal drop-off options across the region, including Tacoma sites that accept aluminum, brass, copper, scrap iron, stainless steel, insulated wire, lead, and zinc. Scrap metal recycling in Tacoma, WA follows slightly different guidelines for Tacoma Solid Waste customers than for broader Pierce County residents, so verify current rules with your specific provider.

For large loads, a private recycling facility that serves the Tacoma area from nearby can offer faster processing, competitive payouts, and flexible drop-off or pickup options depending on load size and location.

What Is the Difference Between Ferrous and Non-Ferrous Scrap Metal?

Ferrous metals contain iron and are magnetic. Non-ferrous metals such as copper, aluminum, and brass do not contain iron, resist rust better, and often carry a higher value per pound.

Do I Need to Sort My Scrap Before Drop-Off?

Sorting by type before you arrive can speed up processing and may increase your payout. Separating copper, aluminum, and brass from steel and iron is a good starting point.

Can I Recycle Copper Wiring and Old Appliances?

Yes. Copper wiring, both bare and insulated, is widely accepted, as are old appliances. Drain any fluids from appliances containing motors or compressors before transport.

Is There a Minimum Weight Requirement to Get Paid?

Requirements vary by facility. Some recyclers pay for steel loads above a certain weight threshold and accept smaller loads free of charge. Contact your facility directly to confirm current policies.
