Located in the city centre of Beijing, the CNPC headquarter is a twenty-five-stories high-end office building. It is the first office building in China to install an Envac automated waste collection system.
Envac has designed and installed 2 separate vacuum systems to handle the complicated waste generated everyday, one Stationary Vacuum System to collect the general waste and a Kitchen Waste System to take care of the food waste from the staff canteen that has a capacity of over 2000 eating guests per day.
Being one of the top office buildings in China, CNPC Office Building has been nominated to the "Annual Selected Building" of Discovery Channel.
