How did the introduction of wheeled plastic containers change the labor process of waste collection?

Answer

It allowed the container to be mechanically lifted and emptied by trucks

The shift to wheeled, durable plastic containers fundamentally changed the waste collection process from one requiring manual labor to one supported by mechanical engineering. Previously, municipal workers or residents had to manually carry or move heavy, loose, or containerized waste. The wheelie bin system, however, was designed to couple with collection vehicles, allowing the trucks to mechanically engage, lift, and empty the containers. This significantly reduced the physical burden on sanitation workers and streamlined the entire logistical operation of waste disposal.
