How could the digital signage industry be greener than it already is?
The one-two punch of quality systems and end of life recycling of components has already become common practice but can always be improved. Displays and media players are most eco-friendly when they operate efficiently. For example, control systems that regulate brightness based on ambient light and trigger message displays based on the proximity of viewers can reduce energy consumption. Greater efficiency could be found in minimizing the need to dispatch repair/replacement before the end of the normal product life of three to five years. As the health of components is monitored, end of life action can be better planned as a service route.
Display and player technologies are 98 percent recyclable as glass, plastic and metal chips are used to make other materials. Improved efficiencies on the part of those who collect and process for recycling will further reduce the impact of the technology industry at large.
Increased replacement of static signage can have the greatest impact. The production, distribution and waste removal/disposal of vinyl and ink signage consumes way more energy than digital signage. In addition, the digital signage can present several messages most relevant to the daypart and target audience.
As digital media technologies continue to advance toward solid-state media players and OLED displays, eco-friendly efficiencies will continue to be realized.
