How do you eliminate the need for 15,000 tons of new steel plus the accompanying 18,000 tons of CO2 involved in its production? Make good use of old steel. This is the concept behind our businesses that focus on remanufacturing, rebuilding and repowering existing Cat® products. Our remanufacturing business allows us to keep thousands of tons of material from landfills, while offering our customers the needed upgrades to minimize their total cost of ownership. Learn more about how Caterpillar is leveraging remanufacturing processes in the 2012 Sustainability Report.
