That's a great question! A community garden definitely needs a robust waste management solution. For a high-capacity urban trash bin, I'd primarily suggest looking at a heavy-duty, wheeled bin with a capacity of 65 to 95 gallons. These are often used commercially and can handle garden waste like weeds, dried plants, and non-compostable packaging.
Look for bins made from durable, UV-resistant polyethylene or galvanized steel to withstand sun and rain. Features like a secure, locking lid are crucial to deter pests and prevent litter from blowing away. Consider getting two bins: one for general waste and another clearly marked for recycling to encourage sustainability.
For areas with lots of green waste, pairing a large trash bin with a dedicated compost tumbler or bin is ideal. This diverts organic material from the landfill and creates valuable compost for the garden. Place the bins on a solid, level surface like concrete or pavers for easy access and stability, ensuring they're convenient for all gardeners but not obstructing pathways.
Finally, check with your local municipality. Some cities offer or subsidize large bins for community projects, and they will have specific rules for waste collection. Investing in a proper bin keeps your garden tidy, supports communal responsibility, and makes maintenance days much smoother for everyone involved.
