Besides efficiency, what public health dimension did the sealed pedal bin afford?

Answer

Containing odors and discouraging pests

In the era before universally convenient garbage collection services, managing household waste cleanly was a significant concern. The foot-operated, sealed nature of the pedal bin provided an immediate public health benefit by effectively containing unpleasant odors and acting as a barrier to discourage the attraction of pests to the rubbish container, thereby adding a layer of sanitation to Gilbreth's primary focus on workflow efficiency.
