AbstractIn today's consumer society little attention is paid to extending the life of a product, even though this would reduce the depletion of resources, the waste volume and environmental degradation.The self-replenishing system creates spiral-loops that minimizes matter and energy flow, and environmental deterioration without restricting economic growth or social and technical progress.The hidden resources of goods and raw materials need to be seen and their potential recognized: then the new notions of value accompanying them can be accepted.
