L’Oréal USA temporarily swapped energy management teams with General Motors earlier this month as part of the Department of Energy’s Better Buildings Challenge SWAP program, which looks at ways in which companies can save energy.

The swaps, which aim to find ways to improve productivity, were filmed and replayed as webisodes on the Department of Energy’s YouTube channel. The two management teams were documented in a fly-on-the-wall style film as they sought ways to increase energy efficiency in the manufacturing processes.

A L’Oréal team explored the General Motors factory in Detroit-Hamtramck while a management from General Motors visited the L’Oréal USA factory in Little Rock, Arkansas.

General Motors was said to have pointed out the high level of employee commitment to energy efficiency at L’Oréal’s USA’s plant, and how personally involved they were with the green mission.

Eric Fox, Manager of L’Oréal’s Little Rock plant, is said to have been instrumental in boosting energy-efficient measures, with Fox’s team installing one of the first solar arrays in the state of Arkansas in 2010, a milestone for the state.

Fox’s team is also said to have since paved the way for a 1.2MW solar array installation, rainwater collection and reuse on site, alongside a biocomposting project in the cafeteria.
