I haven't collected any myself as of yet, but friends of mine that use the coroplast for making storage bins for garages and other household projects have. They told me to go to the local party headuarters (dem/rep/GREEN
) and ask I could help them take down signs after the elections. They can always use the help and don't mind giving the stuff away. Sometimes my friends just ask the home owners what they are going to do with their signs after election time and offer to take them away when they are finished with them. They said this approach works well with businesses because they seem to have the larger signs, sometimes even the full sheet size.
There are so many uses for the stuff. They make milk carton sized storage bins out of 2 layers of coroplast glued together, recycling bins for indoor use, bins for copy/shredded paper in thier office buildings, little storage crates for CD's and computer disks, and whatever else they can think of. They would rather see it used again than end up in the landfill.
