PepsiCo announced it was launching a pilot program in US capital Washington DC to test most climate-friendly vending machines ever in the US. 30 such vending machines will be placed in high consumer traffic places in a bid to test the new CO2 refrigerant systems.




As a member of Refrigerants Naturally! since 2006 and in a move to reduce its carbon footprint and green its image, Pepsi proudly announced its pilot project this week. Featuring its new logo and an environmental sticker on each bottle, the 30 new R744 dispensers will be tested over a period of 18 months in the capital with the aim of rolling them out globally over the next few years.
“We’re constantly looking for ways to make our business more efficient and environmentally sustainable. This field test will help us evaluate the performance and reliability of these new machines in a real-world environment. We hope to get a sneak preview of what sustainable refrigeration could look like on a larger scale,” explained Robert Lewis, vice president of packaging and equipment development for PepsiCo.

More efficient machines

In a move that has been acclaimed by environmental NGO Greenpeace, Pepsi’s new machines will generate 12% less Green House Gas (GHG) emissions than current ones and will use 5.08 kilowatt-hours of energy per day. The CO2 vending machines will be the first of their type to be introduced in the US. The current machines already use 44 percent less energy on average than the machines used than in 2002.
"Many people don't realize that the largest part of a vending machine's GHG emissions - about 95 percent, in fact - come from the energy required to run it. The insulating foam and refrigerant gases are responsible for the rest, and we're committed to reducing all parts of the equation," added Lewis.
In a threefold strategy to reduce the overall environmental impact of the machines, Pepsi is committed to:
- Improving the energy efficiency of its machines
- Eliminating HFCs from the insulating foam in vending machines, coolers and fountain equipment
- Using green refrigerants instead of HFCs
