lean manufacturing's unexpected windfall: a lower carbon footprint
DESCRIPTION
Lean manufacturing, also known as the Toyota Production System, is more than just a way to make your company more profitable, meet competitive challenges, and achieve sustainable competitive advantage. It also lowers your company's carbon footprint. Presented at ABB's Automation and Power World 2013, this presentation describes the ways that Lean Manufacturing can make your company not only more efficient, but also a better corporate citizen.TRANSCRIPT
