10 Things You Didn’t Know Sawdust Can Do

If you’re an avid woodworker, you know that cutting, screwing, sanding, drilling, and similar activities produce a lot of sawdust. All that wood waste can be a headache. It seeps into cracks and crevices along the floor, finds its way inside your gloves and clothes, and coats your workshop with a fine patina of pulverized wood. Sure, you can get rid of it with a thorough vacuuming and a once-over with a damp mop, but the next time you're confronted with piles of sawdust, think twice before you dump this DIY by-product. Instead, consider these 10 smart alternative uses for sawdust derived from natural, untreated wood.

  1. Make Your Own Mulch

    Use Sawdust as Mulch

    Why spend your hard-earned money on pricey bags of wood chips when you can achieve the same result with a pile of sawdust? Spreading sawdust around the base of your garden plants can prevent weeds, help retain moisture, and keep roots cooler—all the benefits of mulch without the high price tag! Just be sure to add a nitrogen component to your garden as well, in order to prevent nitrogen deficiency in the soil.

  2. Hack Your Pet Supplies

    Use Sawdust for Pets

    Sawdust soaks up moisture and absorbs odors, which makes it an ideal substitute for commercial kitty litter.

Plus, little pocket pets like gerbils and guinea pigs will enjoy having a layer of fresh, clean sawdust spread on the floor of their cage as bedding every day.

  3. Sop Up Spills

    Use Sawdust for Concrete Spills

    Sawdust is highly absorbent, which makes it great at soaking up oil, grease, and gasoline spills in the garage or on the driveway. Simply sprinkle sawdust on the spill, wait for it to absorb the liquid, then sweep it away. Repeat as needed until the mess is gone.

    Most municipalities will not let you throw away leftover paint with the garbage, and you should never pour the toxic material down the drain. Instead of hauling unused paint or stain to your local hazardous waste facility, you can dump sawdust into the can and let it sit, uncovered, until the paint solidifies and hardens. You can then safely throw the paint can in the trash without worrying about contamination.
