Repurposing dryer lint
1. Line planters with it.
To keep soil and water inside a planter, line it with dryer lint before adding the soil and plant.
If your lint comes entirely from natural fibers, you can add it to your compost or use it as mulch around plants to help keep moisture in.
3. Make clay out of it for the kids.
You’ll need three cups of the stuff, torn into small piece. Put it into a saucepan with two cups of water. Stir in a cup of flour – gradually! Continue stirring slowly over low heat as you add 3-5 drops of vegetable oil. Once it’s smooth and sticking together nicely, you can pour it onto wax paper to cool.
4. Make paper mache.
Take the same mix of water and dryer lint as in the clay recipe, but add two-thirds of a cup of flour this time. Cook over medium heat, continuously stirring. You know it’s done when you can form peaks with the spoon. Pour on wax paper to cool.
5. Add it to homemade paper.
If you’re into making paper at home out of your recycled shredding and other papers, you can add dryer lint to give it a nice linen-like feel.
6. Make fire starters
Because dryer lint is so flammable, it makes a great fire starter for campers. Pack it into toilet paper rolls for a starter that can burn completely, or just add it to your kindling box.
Things not to do with dryer lint
Don’t give it to birds. Birds have incredibly sensitive respiratory systems, very different from those of other animals. Bits of fabric and lint can get into their nares (nostrils) and cause trouble. Some websites recommend giving it to birds, but this is a bad idea.
Don’t put it in something you don’t want to be flammable. Dryer lint is incredibly flammable on its own, so don’t stuff toys, pillows or bedding with it.
Don’t stuff packages with it – there are better alternatives. I’ve seen this recommended online, but dryer lint will seriously compress while in transit, so don’t expect it to provide any real padding in shipping.
