That's an interesting question that doesn't have a single straightforward answer, as urban trash bins come in many different sizes and materials!
For the standard wheelie bins you see in residential areas (typically 60-120 gallon capacity), an empty bin usually weighs between 10-20 pounds (4.5-9 kg). These are commonly made of durable plastic like HDPE, which keeps them relatively lightweight yet sturdy.
Commercial trash containers are another story entirely. Those large metal dumpsters you see behind restaurants and businesses can weigh anywhere from 100-200 pounds (45-90 kg) when empty due to their heavy-duty steel construction. Their weight varies significantly based on size - from 2-yard mini dumpsters to 8-yard containers.
Public space bins - the ones you find on sidewalks and parks - are typically lighter, weighing 15-30 pounds (7-14 kg) empty. Municipalities choose materials that balance durability with practical handling for sanitation workers.
Several factors affect the final weight: material composition (plastic vs. metal), wall thickness, reinforcement features, and additional components like wheels and lids. So while there's no universal weight, this should give you a good sense of what to expect when handling empty urban trash bins!
