Any home cook knows you should never pour used cooking oil down the drain, because it can cause plumbing problems. But the alternative can mean tossing tons of soaked paper towels in the trash, where they surely will end up in a landfill. So, what to do? Take the cooled, used cooking oil out to the yard and use it to kill pesky weeds. Not only will cooled oil kill tough weeds, but the oily mixture will prevent them from coming back. And since it's vegetable oil, it also will biodegrade slowly in the ground.
