dilemma• Our profits depend on increasing production which
leads us to …
Increase our material use
Increase our energy use
Increase our waste generation
Increase stress on natural resources
Increase our environmental impact

Increasing productivity
Efficiency = input + materials + energy + value added + waste
product
Strategy reduce… Energy – green building, LEED, energy conservation
Materials – reduce scrap, 6 sigma
Waste – recycling, 6 sigma
