When Siemens sees a feasible way to save resources and improve efficiency, the company takes it.

Case in point: The global industrial manufacturing and technology business recently opened one of the first all-electric powder coating paint lines for the electrical distribution industry in the U.S., in Grand Prairie, Texas, to cut down on natural gas consumption.

• Siemens wholly replaced the original paint line to an all-electric system, which has reduced natural gas consumption by more than 90%, according to the company.
• “The timing was fortuitous,” said Stacy Mahler, U.S. head of sustainability for Siemens Smart Infrastructure. “We’d done an assessment of [the facility] and saw that our Scope 1 emissions were coming mostly from the paint line, which at 30 years old was due for replacement. The team realized that there was an opportunity to make an investment that would not only modernize the process but also lower the carbon footprint and help to manage the volatility in energy cost.”
• That change—made without interruption to plant operations because the new line was built alongside the old line—is part of Siemens’ larger goal to achieve a net-zero carbon footprint across its operations by 2030. It’s 55% of the way there already.
• Next up: assessing other company facilities globally for the same all-electric upgrade. One outcome of the effort in Grand Prairie is a cross-business team of experts working to replicate success at Siemens’ other facilities, like the newly expanded facility in Pomona, California, while sharing their knowledge with the broader manufacturing community.

Waste not: At its Spartanburg, South Carolina, site, Siemens is extracting and reusing waste oil found in materials on the floor.

• “We’ve partnered with a third-party company that provides the infrastructure within our own facility to take oil from rags and other materials, absorb it and then recycle or downcycle it,” Mahler told the NAM, adding that in the latter, the oil can be made available for other downstream applications.
• The impact is big, recycling about “3,000 pounds of oil-absorbent material that otherwise would have gone to landfill.”
