That's a great question! A community garden definitely needs a sturdy, high-volume waste solution. For a very large capacity urban trash bin, I'd recommend checking out a few key places.
First, look into commercial janitorial supply companies. They specialize in heavy-duty bins meant for public spaces and businesses. Brands like Rubbermaid Commercial or Toter offer wheeled carts with capacities from 65 to 100 gallons that can handle garden waste like weeds, branches, and non-compostables.
Another excellent option is municipal or city government surplus sales. Many cities sell their used but robust street bins or park bins at a discount. These are built to withstand public use and weather.
Don't overlook online industrial retailers like Grainger, Uline, or WebstaurantStore. Filter your search for "outdoor commercial trash cans" or "wheeled utility carts." You'll find galvanized steel or durable plastic models designed for high traffic.
Finally, connect with local landscaping companies. They often know the best suppliers for large-scale outdoor equipment and might even offer bins as part of a service.
A quick tip: consider getting two bins—one for general waste and one for recyclables. Make sure the bin has a secure lid to deter pests and is easy for your local waste service to empty. Happy gardening, and thanks for keeping your green space tidy
