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.

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.

Sawdust in Leftover Paint

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.
