At our facilities, we work to minimize our environmental impact by focusing on energy conservation, GHG emission reduction, water conservation and waste reduction. We have set energy-efficiency targets in our operations since 1998 and have set GHG emission-reduction targets since 2003. We currently have operational targets for an increased reliance on alternative and renewable energy and a reduction in energy intensity and GHG emissions intensity.
As a manufacturer of heavy equipment, some of Caterpillar’s operations are energy-intensive. But even in our most energy-dense environments, Caterpillar employees have found ways to implement innovative energy solutions that reduce our energy costs as well as our environmental impacts.
With respect to water, we recognize the far-reaching economic, social and environmental implications that water scarcity may have in the future, and have taken steps to reduce our consumption.
Finally, we are minimizing waste in our processes not only to reduce costs, but also to reduce our use of materials, energy, water and land. We ultimately aim to reduce all waste generated by our production processes.
By taking a critical look at every phase of our operations, teams have been able to uncover unexpected methods to reduce our footprint while maintaining or improving performance and customer satisfaction.
Improving Our Manufacturing Footprint
Caterpillar continued to make progress in reducing environmental impacts from our own operations.
Making Better Use
of Process Water
Our Seguin Engine Center in Texas manufactures, tests and paints diesel engines for Caterpillar customers, a process that requires large volumes of water. A micro-filtration system allows us to reuse water, reducing wastewater from the engine testing process by 90 percent.
Yellow Paint With
Painting processes typically require a significant amount of highly treated process water. In our Xuzhou, China, facility, we were obtaining water from the city and treating it for use in the paint line. Now, we are collecting condensate water for reuse, reducing the fresh water needed for the paint line. Implemented in November 2016, this process is saving about 40,000 gallons of water per year.
A Space-Age Solution
for Acid Etching
Our Advanced Materials Technology team borrowed a technique from the aerospace industry to perform acid etch checks without methanol, improving the safety of the process while reducing hazardous waste and hazardous air pollutants. A new facility in Cienega de Flores, Mexico, was able to replicate the technique and was designed to use this process from the start.
Bright Ideas for
The Material Handling & Underground Division at our Thiruvallur, India, facility leveraged its location’s average of 2,700 hours of sun per year by installing a 285 kW Cat® microgrid – helping reduce GHG emissions 32 percent in two years.
