I have disassembled an old vinyl shed and removed all the metal, etc. Now I need to know how and where to dispose of the vinyl walls?
If you have municipal trash collection, you'll want to contact the company in charge of pickup. It's quite common for them to have a website, which typically has information about how to handle various types of waste.
If you're not sure who handles the collection. That information is usually available on the town/city website, or by calling the town/city.
If you take your waste to the dump (not sure if folks still have to do this), you could simply ask someone on your next trip.
Just the trash, if you can cut it up. Or, you'll have to setup for a Bulk Trash Pickup with your Township, likely $10 for that stuff. But no recycling program will accept that & only Blinds To Go takes working vinyl blinds.
