Note: Ireland produces about 38 g TEQ/yr compared to other European countries ranging from 50 – 1123 g-TEQ/yr.

Matters to ponder! Most of current technology is focused on treating waste that has already been generated What about reducing the need to manufacture less for less consumption? Ensuring manufacturing processes are 110% efficient and do not produce waste at all. How to contain the huge appetite for modern lifestyle? Ensuring zero waste production by the general population?
