No worries on the delay - it was only by happenstance that I saw your reply.
We gathered the data through city websites, calling city recycling hotlines, and asking the recycling MRFs (material recovery facilities) personally when we couldn't get answers. It took a lot of elbow grease, which is why I'd be happy to share the info.
Hi Jes, Congratulations on your win, and for fighting the good fight! I'm attacking the same issue but from another angle. I've got tons of data on US local recycling programs I'd be happy to share with you. Let me know how I can help!
Aaryaman, I see you're from Austin! Austin is on our site. We cover everything from batteries to bubble -wrap to chopsticks. http://recyclebycity.com Please let me know if you find what you're looking for - or what you think we could improve. I'd love to hear from you both. Cheers!
