Cemex USA and Ford receive EPA Energy Star recognition

Initiatives aimed at energy management and greenhouse gas emissions reduction garner Cemex and Ford EPA 2010 Energy Star awards.


The U.S. Environmental Protection Agency (EPA) has named Cemex USA a 2010 Energy Star Partner of the Year for outstanding energy management and reductions in greenhouse gas emissions. In related news, Ford Motor Companyearned its fifth straight Energy Star Award for Sustained Excellence.

Cemex USA, an Energy Star partner since 2004, is receiving the Energy Star Partner of the Year award for strategic energy management and a commitment to save energy across its entire operation that has resulted in significant energy and financial savings. This isthe second year that Cemex USA has been named Partner of the Year. In 2009,Cemex reduced its overall energy intensity by 2.2% as a result of its energy management program using Energy Star guidelines. More than 1.1million MMBTUs were saved through such measures as commissioning two new cementlines using state-of-the-art vertical roller mills for finish grinding,replacing and repairing compressed air systems, and upgrading plant lighting.This energy savings resulted in cutting 107,500 metric tons of CO2 emissionsand is equal to providing electricity to 14,900 American homes for one year, oravoiding emissions from about 19,700 passenger vehicles.

The energymanagement program at Cemexemploys a corporate energy management team and a site energy teamat each plant to deliver on the company's energy conservation and sustainable manufacturing practices. Cemex cement plants in Clinchfield, GA,Davenport, CA, Knoxville, TN, Louisville, KY, and Wampum, PA, have all receivedEnergy Star certifications for their work to protect the environment throughenergy efficiency.

Ford's recognitionresults from the company's 2009 energy efficiency improvement of 4.6%,resulting in savings of approximately $15 million. Actions that have enabledFord's energy efficiency gains include updated heating and lighting systems andadvanced computer controls. The 2010 award marks the fifth consecutive year thatFord has been recognized with the EPA's Energy Star Award for its actions toreduce the amount of energy used to manufacture vehicles.

Since 2000, Ford's U.S. facilities have improvedenergy efficiency by more than 30%. That's equivalent to the annual energyconsumed by more than 110,000 homes. Actions taken by Ford since 2000 that havecontributed to its overall energy efficiency improvement include:

  • using flexible tooling to assemble multiple vehicles on the sameproduction line, which requires less manufacturing floor space andoptimizes plant utilization;
  • facility lighting system updates by replacing inefficienthigh-intensity discharge fixtures with up-to-date fluorescent lights andcontrol systems;
  • upgrading paint process systems, including booth air handling andimproved emission controls;
  • continued development of Ford's "Paint Shop of theFuture" processes, including fumes-to-fuel that turns paint fumesinto electricity, the 3-Wet painting process that significantly reducesthe footprint and energy use of paint booths, and zirconium oxidepretreatment that uses less energy to inhibit surface corrosion;
  • installation of advanced computer controls on all North Americanplant air compressors for paint shop applications and pneumatic tools;
  • use of a PC power management program to improve global energyefficiency with an estimated reduction in the company's carbon footprintof between 16,000 and 25,000 metric tons annually;
  • a "Go Green" dealership sustainability program to improvethe energy efficiency of Ford and Lincoln Mercury dealerships;
  • aggressively curtailing energy use during extended productionshutdown periods;
  • leveraging the Energy Star program through employee energyawareness communications and events, development of energy modeling andanalysis tools, and replication of industry best practices; and
  • updating heating systems at manufacturing facilities by replacingoutmoded steam powerhouses with digitally controlled direct-fired naturalgas air handler.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
