What was the primary driver for the development of the wheeled container known as a wheelie bin in the 1960s?

Answer

Facilitating logistical efficiency with mechanized collection trucks

The introduction of wheeled bins in the 1960s was driven primarily by the need for logistical efficiency in municipal waste management. As collection systems became mechanized, there was a need for a container that could interface effectively with new collection vehicles. These durable, plastic, wheeled bins were designed so that they could be easily moved to the truck and then mechanically lifted and emptied by a single worker. This system eliminated the need for manual lifting and carrying of heavy sacks or containers, greatly increasing the speed and ergonomics of the waste collection process.
