Abstract
The consumption of mineral resources has grown dramatically during the 20th century. This massive increase has caused the problems of resources exhaustion and environmental pollution during the past twenty years. As a result, the necessity of resources recycling rises year by year.
In this paper, 1) definition and signification of resources recycling, 2) history of mineral consumption and perspective of resources supply, 3) relation between social system and resources recycling, 4) examples of machines for resources recycling are outlined.
