World’s first eco-friendly compressed gas siphon for whipping cream

Whipped cream and foamed milk add value and customer satisfaction to coffee bought on the high street, but they come with a burden on the environment.

Currently, whipping cream and foaming milk require nitrous oxide (N₂O) as a propellant and foaming agent, which is delivered in single-use aerosol cans and siphons that are refillable with N₂O charger bulbs.

N₂0, however, has a global warming potential nearly 300 times that of carbon dioxide (CO₂).

In its 2018 Baseline Environmental Report, Starbucks said the N₂O used in its whipped cream accounted for half its global Scope 1 emissions that year. The report declared an N₂O emissions value for the company equivalent to nearly 160 million kilotons of CO_2, representing the use of 67 million steel N₂O charger bulbs in a year.

Now, Cambridge start-up Triple Line Technology has created TLT-Foamer, the world’s first eco-friendly compressed gas siphon for whipping cream and foaming milk using compressed air or nitrogen.
