Ricoh installed an eco billboard in the suburbs of London in June 2011.The billboard is located in an area between Heathrow Airport and Central London. The eco billboard is 100% powered by efficient wind and solar power generation systems and is equipped with an indicator showing how much electricity is remaining in the battery. The lighting method is changed depending upon the amount of the electricity remaining in the battery.The eco-billboard will communicate the Company’s stance to promote “sustainable environmental management” that simultaneously conserves the environment and creates profit.
