Sawdust and wood shavings often end up in the trash after a woodworking project, but they can come in handy for several jobs around the house and yard. Before throwing them away, check out these simple ways to reuse leftover wood scraps and make the most of what you already have.
1. Fire Starter
Dry sawdust from clean, untreated wood can be mixed with melted wax to make small fire starters for fireplaces, wood stoves, or outdoor fire pits. Avoid scattering loose sawdust over open flames, since fine wood particles can ignite quickly.

2. Spill Absorber
Sawdust can soak up small spills of oil, grease, and other liquids on garage or workshop floors. Spread it over the spill, let it absorb the liquid, then sweep it up and follow local disposal rules for the material involved.
3. Compost Material
Untreated sawdust adds carbon to a compost pile and can help balance wet materials like fruit scraps and fresh grass clippings. Add it in small amounts and mix it well with other compost ingredients to keep the pile from becoming too dense.
4. Pet Bedding
Some wood shavings are suitable for bedding for small animals, but the wood type and dust level matter. Use only bedding approved for your pet’s species, and avoid sawdust from treated, painted, or chemically finished wood.
5. Homemade Wood Filler
Mixing fine sawdust with wood glue creates a thick paste that can fill small nail holes, gaps, and cracks in woodworking projects. Let it dry completely before sanding, and test the mixture on a hidden area first because the color may differ from the surrounding wood.

6. Traction Aid for Slippery Surfaces
A light layer of coarse wood shavings can add grip to slippery outdoor surfaces in cold or wet weather. Use them sparingly, keep them away from drains, and clear them away once conditions improve so they don’t create another slipping hazard.
7. Garden Path Covering
Wood shavings can give garden paths a natural look while making bare soil more comfortable to walk on. Use untreated wood, keep the layer manageable, and add more as the material breaks down or gets scattered.
8. Weed Barrier
A layer of untreated sawdust can block some light from reaching weeds between garden rows or around established plants. Keep it away from plant stems, avoid mixing large amounts into the soil, and add more as needed because it breaks down over time.
9. Pet Waste Absorbent
Clean, untreated wood shavings may help absorb moisture in some outdoor pet areas or animal enclosures when the material is safe for the species. Don’t use ordinary sawdust automatically in litter boxes, and dispose of contaminated material according to local waste guidance rather than assuming it can be composted.

10. Drying Out Old Paint
For small amounts of leftover latex paint, sawdust may help absorb liquid and make disposal easier if local waste guidelines allow it. Check the paint label and your local disposal rules first, and don’t use this method for oil-based or hazardous paint unless the relevant guidance permits it.
