- Check blade condition: Severely damaged or non-ferrous blades (e.g., some diamond blades) may need specialized disposal.
How to Recycle Saw Blades: Your Complete DIY Homeowners Guide
That dull circular saw blade gathering dust in your garage? The broken reciprocating blade from your last demo project? Don’t just toss them in the trash! Saw blades are almost entirely made of valuable metal – steel, carbide, or even diamond – that can be recycled and transformed into new products. Recycling them keeps heavy metals out of landfills, conserves resources, and often puts a little cash back in your pocket. This guide walks you through the simple, safe process of recycling your old saw blades, whether you’re a weekend warrior or a seasoned DIY pro. You’ll learn how to prepare blades, find the right recycling location, and even get creative with repurposing before you recycle.
Why Bother Recycling Saw Blades? It’s Not Just About the Trash!
You might think, “It’s just one blade.” But multiply that by millions of DIYers and professionals, and the waste adds up fast. Saw blades are primarily steel (ferrous metal), a material that’s infinitely recyclable without losing quality. Here’s why recycling matters:

- Environmental Protection: Manufacturing new steel from raw ore is incredibly energy-intensive and polluting. Recycling steel uses up to 75% less energy and significantly reduces greenhouse gas emissions and mining waste.
- Resource Conservation: Recycling blades preserves iron ore, coal, and other finite resources needed to make new metal.
- Landfill Reduction: Metal takes centuries to decompose in landfills. Recycling keeps these durable materials out of the waste stream.
- Potential Cash Back: Many scrap yards pay for clean ferrous metal like steel blades, especially if you bring in a decent quantity. While it won’t fund your next tool purchase, it’s better than nothing!
- Responsible DIY: As homeowners who care about our projects and our planet, recycling tools is the right thing to do. It completes the lifecycle of the materials we use.
Before you start, remember: safety is non-negotiable. Saw blades are razor-sharp, even when dull, and can be heavy. Rusty blades pose additional risks. Always prioritize protection.
Step 1: Gather Your Tools & Prioritize Safety (The Non-Negotiable First Step)
Never skip this step. Handling used saw blades carelessly leads to serious injuries. Here’s what you need:

Essential Safety Gear
- Cut-Resistant Gloves: Heavy-duty mechanics gloves or dedicated cut-resistant gloves (ANSI Level 4 or higher) are mandatory. Leather alone isn’t sufficient against sharp edges.
- Safety Glasses: Protect your eyes from flying debris, rust flakes, or metal shards during cleaning.
- Sturdy Work Boots: Protect your feet if a heavy blade drops.
Preparation Supplies
- Stiff Wire Brush or Steel Wool: For removing built-up pitch, sap, and rust.
- Degreaser or Rubbing Alcohol: Helps break down sticky residues.
- Old Rags or Paper Towels: For cleaning and drying.
- Sturdy Container: A metal bucket, old coffee can, or heavy-duty plastic bin with a lid to store cleaned blades safely until recycling. Label it clearly!
- Marker: For labeling your container.
Safety Checklist Before Touching Any Blade
- Inspect for Damage: Look for cracks, deep rust pits, or missing teeth. Severely damaged blades might be harder to handle safely.
- Secure the Blade: If possible, clamp a small blade in a vise (with padding to protect teeth) for cleaning. Never hold a large circular blade freehand.
- Work in a Clear Area: Ensure good lighting and no tripping hazards. Keep children and pets far away.
- Mind the Edges: Always assume every edge is sharp. Handle blades by the center hub or arbor hole, not the cutting edge.
- Circular Saw Blades: The most common DIY blade. Typically steel with carbide-tipped teeth. Highly recyclable as ferrous metal. Tip: If you’re unsure how to remove it safely, check our guide on how to change a blade on a circular saw for removal basics before recycling.
- Band Saw Blades: Long, continuous loops of steel. Very recyclable. Often have welded seams. Related: Learn proper maintenance like how to sharpen band saw blades to extend life before recycling becomes necessary.
- Reciprocating Saw Blades: Shorter, thicker blades for demolition. Usually high-carbon steel. Highly recyclable. See our reciprocating saw blades guide for type details.
- Hole Saws: Cylindrical blades with a pilot drill. The metal body is recyclable, but the pilot drill bit (often HSS) and any plastic arbors must be separated.
- Jigsaw Blades: Small, thin blades. Recyclable, but their small size means you’ll need a collection of them to make scrap yard trips worthwhile. Bundle them securely.
- Diamond Blades (Concrete/Masonry): The steel core is recyclable, but the diamond segments (metal bond + diamonds) are tricky. Most scrap yards accept the core but may not pay for the diamond portion. Call ahead. Severely worn diamond blades might need special disposal – check locally.
- Specialty Blades (Dovetail, Back Saws): Usually high-quality steel. Highly recyclable, but their value as antiques or for restoration might be higher than scrap. Consider selling first!
- Good Condition (Dull but Intact): Can often be resharpened! This is the best option before recycling. Resharpening services exist for many blade types.
- Damaged (Broken Teeth, Cracks, Warped): Generally not suitable for sharpening. Proceed to recycling or creative repurposing.
- Severely Rusted or Corroded: Still recyclable as metal, but cleaning is crucial for safety and value. Heavy rust might indicate structural weakness – handle with extreme care.
- Non-Ferrous Components: Some blades have aluminum hubs or plastic parts. Remove these non-metal pieces before taking to a scrap yard, as they contaminate the ferrous metal stream.
- Initial Wipe Down: Use a dry rag to remove loose sawdust, wood chips, and large debris. Tap the blade gently against a solid surface (like a concrete floor – carefully!) to dislodge chunks.
- Tackle Pitch & Sap: This is the toughest part. Apply degreaser or rubbing alcohol to a rag or directly to the blade. Let it sit for 5-10 minutes to soften the gunk. Scrub vigorously with the wire brush or steel wool, focusing on the teeth and gullets (spaces between teeth). Work in the direction of the teeth to avoid damaging them. For stubborn spots, reapply solvent and repeat. Patience pays off here – clean blades are safer and more valuable.
- Rust Removal (If Applicable): For surface rust, use steel wool or a wire brush. For heavier rust, a rust dissolver product can help, but ensure it’s safe for metal and rinse thoroughly afterward. Avoid harsh acids unless you’re experienced.
- Final Rinse & Dry: Wipe down with a clean, damp rag to remove any solvent or rust residue. Immediately dry the blade COMPLETELY with a clean, dry rag. Moisture leads to flash rust. You can also let it air dry in a warm, low-humidity area for several hours.
- Inspect Again: Once clean and dry, do a final safety check for hidden damage or remaining sharp edges.
- Remove plastic or rubber guards, arbor washers, or pilot drill bits from hole saws.
- Take off any non-metal shims or spacers.
- These non-ferrous parts usually belong in regular trash (check local rules) or specific plastic recycling – they have no value in the metal scrap stream.
- Place cleaned, dry blades in your sturdy, labeled container.
- For circular blades, you can stack them carefully with cardboard between them to prevent teeth from damaging each other (and you!).
- For reciprocating or jigsaw blades, bundle them together with strong tape (avoiding the cutting edge) or place them in a small box.
- Store the container in a secure, dry place out of reach of children.
- Why they’re ideal: They specialize in ferrous (iron/steel) and non-ferrous metals. Saw blades are prime ferrous scrap.
- How to find them: Search online for “scrap metal yard near me” or “ferrous scrap recycling [Your City]”. Check directories like iScrap App.
- Call Ahead – Crucial! Policies vary significantly:
- Do they accept small quantities from the public?
- What are their hours for public drop-off?
- Do they pay per pound? (Current ferrous scrap prices fluctuate; check sites like ScrapMonster for estimates).
- Do they require blades to be clean and separated from non-metal parts? (Most do).
- Do they have any size or quantity restrictions?
- What to expect: You’ll likely drive to a scale, get weighed (tare weight), drop off your blades, and get weighed again. Payment is usually cash or check on the spot based on the net weight and current market rate. A single circular blade might yield $0.50-$2.00; a bucket full is more worthwhile.
- When to use: If you have a large quantity, non-ferrous blades (like some specialty blades), or if local scrap yards are inconvenient. Also good for blades with hazardous coatings (rare).
- How to find: Check your city/county waste management website for HHW collection schedules and accepted items. Search for “specialty metal recycling event [Your Area]”.
- Note: These events are often free for residents but may have specific drop-off times and limits. They might not pay you, but they ensure proper recycling.
- Check with major stores: Some home improvement centers (like Home Depot or Lowe’s) occasionally run tool recycling events, sometimes partnering with manufacturers. Call your local store’s customer service to ask.
- Manufacturer Programs: A few blade manufacturers (like Diablo or Irwin) have explored take-back schemes, but these are not widespread. Check the manufacturer’s website under “sustainability” or “recycling”.
- Reality Check: Don’t count on this as your primary method – scrap yards are far more reliable for regular recycling.
- Curbside Recycling Bin: As mentioned, this is dangerous and will contaminate the entire load.
- Regular Trash: The absolute last resort. Landfilling recyclable metal is wasteful and environmentally harmful.
- Donation (Unless Truly Usable): Only donate blades that are sharp, undamaged, and in working condition to tool libraries or community workshops. Don’t dump your broken blades on them.
- Plant Markers: Clean a small jigsaw or reciprocating blade. Paint the top with weather-resistant paint and write plant names on it. Bury the blunt end in the soil.
- Edging or Borders: Use a section of a broken band saw blade (carefully filed smooth on edges!) as a unique, durable border for a garden bed or path. Secure it with stakes.
- Bird Feeder Hanger: Bend a sturdy reciprocating blade section into a hook shape (use a vise and careful hammering – wear heavy gloves!). Hang it from a tree to hold a bird feeder.
- Wind Chime Element: Drill a hole near the top of a small blade section. Suspend it with wire from a larger piece to create a unique, metallic wind chime.
- Heavy-Duty Hooks: Bend the end of a reciprocating blade into a hook. Mount it securely on a wall stud to hang heavy tools, cords, or bikes.
- Tool Rest or Stop: A small section of circular blade (teeth filed smooth) can make an excellent, durable stop block for your panel saw or workbench.
- Drawer Organizer: Cut a small rectangle from a thin blade (use an angle grinder with extreme caution!). File all edges smooth. It makes a tough divider for screws or small parts.
- Wall Art: Clean and polish a visually interesting blade (like an old dovetail saw). Mount it securely on a wooden plaque for rustic workshop decor.
- File ALL Edges Smooth: This cannot be overstated. Use a metal file or angle grinder with a grinding wheel to remove every trace of sharpness from any part that might be touched. Test with your gloved hand.
- Wear Full Protection: Gloves, eye protection, and hearing protection are essential when modifying metal.
- Secure Workpiece: Always clamp the blade section firmly before cutting or bending.
- Consider Weight: Metal is heavy! Ensure your mounting solution (hooks, screws) is rated for the weight.
- Possible Reasons: They only buy large quantities from businesses; your blades aren’t clean enough; they have a temporary glut of ferrous metal; non-metal parts weren’t removed.
- Solutions: Call another yard. Double-check your cleaning and separation. Ask if they have a minimum weight requirement (collect more blades). Inquire about HHW events.
- Solution: Be patient. Use heat (carefully!): Hold the blade near (not in!) a heat gun or hair dryer on high to soften the pitch, then immediately scrub with solvent and wire brush. Repeat as needed. Soaking in acetone *might* help for some pitches, but test on a small area first and ensure good ventilation.
- Solution: Call scrap yards first. Explain it’s a diamond blade. Most will take the steel core but may not pay extra for the diamond segments. Some specialized industrial recyclers handle diamond tools – search online. If unusable, HHW events are often the best bet.
- Solution: Wear extra-thick gloves. Place the rusty blade inside a heavy-duty plastic bag before handling to contain flakes. Clean outdoors. If rust has caused deep pitting or holes, the structural integrity is compromised – handle with extreme care or consider it hazardous waste (check local rules).
- Solution: Ask a friend or neighbor for a ride. Check if your city offers bulk metal pickup as part of waste services (rare, but possible). Save blades until you have a ride or enough to make it worthwhile.

Separate Non-Metal Parts
Safe Storage Until Recycling
Clean blades are safer to handle, easier to transport, and more likely to get you the best price at the scrap yard.
Step 4: Find the Right Place to Recycle Your Saw Blades
This is where many people get stuck. Never put saw blades in your curbside recycling bin. They are too dense, can damage sorting machinery, and pose a severe hazard to workers. Here are your best options:
1. Local Scrap Metal Yards (The Best Option for Most Blades)
2. Municipal Household Hazardous Waste (HHW) or Specialty Recycling Events
3. Tool Retailer Take-Back Programs (Limited Availability)
What NOT to Do
Calling ahead saves you a wasted trip and ensures your blades are accepted.
Step 5: Creative Repurposing – Give Your Blade a Second Life!
Before you head to the scrap yard, ask: “Could this blade be useful again?” Repurposing is the most sustainable option, saving the energy needed for melting and reprocessing. Here are DIY ideas for homeowners:

Even with the best prep, you might hit a snag. Here’s how to handle common issues:
“The Scrap Yard Won’t Take My Blades!”
“My Blades Are Covered in Thick Pitch – Help!”
“I Have a Diamond Blade – What Now?”
“The Blades Are Too Rusty to Handle Safely”
“I Don’t Have a Car to Get to the Scrap Yard”
Persistence and a little research usually overcome these hurdles.
