Pepsi Tests Green Vending Machines
LittleWolf on April-2-09
PepsiCo Inc is testing greener vending machines to reduce its environmental footprint and give businesses some relief on their electric bills. The test involves 30 machines in the Washington, D.C. area. Pepsi hopes to begin rolling them out worldwide over the next several years.
The new machines use 5.08 kilowatt-hours of energy per day, down about 15 percent from a nationwide average of 6 kilowatt-hours used by current machines, which already use 44 percent less energy on average than similar machines used six years ago.
The new machines also emit about 12 percent less greenhouse gas, in part by keeping the drinks cool with carbon dioxide instead of the usual hydrofluorocarbons (HFCs), which scientists say contribute to global warming.
