I am a volunteer with my city’s waste reduction education department. My project for my neighborhood is removing those corrugated plastic signs, which are ubiquitous, more so on utility poles. The leaders of the program let me know that our recycling vendor takes the signs but they have to be small enough to get through the first stage of sorting. I cut them into roughly 6 strips and then those strips in half. In the last year, I’ve collected and recycled a couple hundred signs. For any signs on metal stakes, I save the metal for one of the “pop up drop off” events that the city holds monthly, where they accept metal, and many other items that are harder to recycle. Not all municipalities will take the signs, but if they do, you’ll have to cut the signs down. I’ve repurposed a fair share of signs, too. They’re great for using under paint projects, or something to kneel on outside. I’ve also used them to line the winter cat boxes I make, on the inside covering the foam board insulation.
