What are the implications of the law of conservation of matter and energy for recycling and waste disposal?

This means that after a raw material has been used, either it must be used again (recycled) or it becomes a waste product that requires disposal. It may end up in some municipal dump; it may literally go up in smoke, contributing to atmospheric pollution; or it may be transformed into heat, warming up adjacent waterways and killing aquatic life.
