Agenda
�FNGP Seal & Gasket recast from Lean Manufacturing to Green Manufacturing
10
�Transition from Batch & Queue to Single Piece Flow
Agenda
11
�Reduce my company’scarbon footprint?
�Reduce my industry’scarbon footprint?
What are the traditional ways to:
12
�Commuting�HVAC systems�Industrial processes (ovens to fork lift trucks)
Atmospheric emissions
13
�Duplicated servicesTwo airlines that fly halffull planes from O’Hareto Wichita may decide to code-share.
Atmospheric emissions
14
�Sewage�Industrial processes�Underutilized plating operations may be consolidated.
Wastewater emissions
15
�From lights and HVAC�From industrial processes
�A lean manufacturer can speed the exit of high-consuming operations.
