Mr. Trash Wheel Dumpster Dive 2025! Results are in! Dozens of volunteers hand sorted and counted common litter found in streams and outfalls around Baltimore Harbor. We found nearly 2,000 beverage containers that would be covered by a bottle bill if the Maryland General Assembly passes the Recycling Refund and Litter Reduction Legislation (a “bottle bill”).

The latest data from the 2024 Dumpster Dive reaffirms the effectiveness of policy in our mission to tackle litter. We're seeing a steady decline in the presence of plastic bags and polystyrene pieces in Professor Trash Wheel's dumpster after bans went into effect!

We all love the Trash Wheels here in Maryland but did you know that Toronto, Canada might be getting their very own Trash Wheel soon?

Over 200 Volunteers showed up to the Volunteering Untapped Baltimore and Baltimore Waterfront Partnership Annual Dumpster Dive! The focus, trash data!
