Abstract

This paper describes the future of waste management in the 21st century using the physical concept 'entropy'.

The present social system (defined as the 'high entropy society') will soon be at a dead lock due to earth-scale environmental contamination. Unfortunately, the present disposal methods for solid waste such as incineration and landfilling can solve only limited environmental problems and increase entropy of the earth. Recycling is expected to be an effective method to reduce solid waste. However, in the 'high entropy society' where private sectors take priority in economic activities, recycling can never be a final solution. Therefore, a new social system defined as the 'low entropy society' should be established. In this society human beings live in harmony with the ecological system of the earth. Activities of private sectors in pursuing economic profits will be strictly limited and producers will have a responsibility to either use or provide as raw materials the waste they generate.

Key words: entropy, recycling, waste, earth-scale environmental contamination
