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

Strategy reduce… Energy – green building, LEED, energy conservation

Materials – reduce scrap, 6 sigma

Waste – recycling, 6 sigma
