Watch £20 per ton (1955) Official Trailer

Wintry snowfall in a factory yard contrasts with the furnaces burning within. This film follows the eye of the firm's accountant as he traces waste and excess about the works. The concerns for fuel efficiency and reducing pollution are all about economy, even when the narration talks of coal heating up the atmosphere. Among the wastrels are the workers, who are shooed away from a warming stove.
