When energy data becomes a performance driver at Doulux

Doulux is a leading player in the paper and hygiene industry in Réunion, specializing in the production of sanitary and household paper products. Based in Le Port, the company combines strong local roots with industrial innovation. Its ambition: to deliver high-quality, accessible solutions that showcase the unique identity of Réunion.

Rapid identification of energy overconsumption, particularly on compressors

Reduction of energy losses through optimized equipment operation

Improved operational responsiveness with daily monitoring of consumption deviations

The start

At first, Doulux aimed to implement a monitoring system for its production lines. The main objective was to better manage operations and maintain an accurate record of equipment speed and energy consumption.

The idea was to take a closer look at electricity usage to detect inefficiencies, identify waste, and uncover new opportunities for energy savings.

“Until then, data collection was carried out manually through production sheets filled in by operators,” explains Loïc Mayeresse, Production Manager at Doulux. “This method lacked the responsiveness and precision needed to detect deviations in real time.”

The solution

Following these findings, Doulux made the strategic decision to focus exclusively on energy monitoring.

The solution was deployed using electrical consumption sensors installed on key equipment, providing real-time visibility into energy usage. Building on these initial results, Doulux recently decided to expand the scope by adding compressed air sensors, after identifying several air leaks that represented potential additional savings.

“The idea was simple,” says Mayeresse. “Not to waste time developing an internal solution, but to rely on an efficient system capable of automatically collecting data and giving us a clear view of our actual consumption.”

The results

In just three and a half months, the benefits became clear. The company was able to detect significant overconsumption — particularly in compressors — and adjust their operations to reduce these losses.
