'resource-saving' originates from the combination of 'resource' and 'saving', where 'resource' refers to a supply of materials or assets, and 'saving' implies the act of conserving or economizing.

'resource-saving' evolved from the need to describe products or practices that conserve resources, becoming a common term in environmental and economic discussions.

Initially, it meant 'conserving resources', and this meaning has remained consistent in modern usage.
