About Nestlé

4. Nestle Policy on Environmental Sustainability
…We use safe and efficient natural refrigerant
alternatives for industrial refrigeration
installations and implement new solutions to
improve their performance when we build,
construct and renovate facilities…
Nestle has invested in a significant phase out
program over many years and has made great
advances in the reduction of ozone depleting
refrigerants to date

5. Refrigerants in Nestlé
AOA
84%
EMENA
91%
AMS
95%
Above 90% Natural in industrial refrigeration globally as a result of our early phase-
out and natural refrigerant strategy, which started in 1986.

6. Some of our achievements:
25.7% of electricity obtained from renewable sources.
In some markets, such as Germany, UK and Ireland, Switzerland, Hungary, Czech Republic, Poland, Austria, Italy and
Brazil, we procure 100% renewable electricity.
33.2% reduction in greenhouse gas emissions per tonne of product since
2007
Since 2016 all new ice cream chest, upright and island freezers use natural
refrigerants.
Since 1992, we spent CHF 289 Million to phase out synthetic refrigerants by
natural refrigerants

7. Industrial Refrigeration
General Strategy
• CO2 / NH3 cascade
• CO2 brine
Negative Temperatures
All facilities
• NH3 Chillers
Positive Temperatures
Hydrocarbon chillers are now also acceptable for use in Nestle.
A system has recently been installed in New Guinea, as well as a number of systems
in Europe.
Priority to Natural Refrigerants

8. Current R22 Phase Out Projects
⚫ CO2 Plant: cooling -30deg brine (PGB/Ammonia condensing): Awaiting Commissioning
⚫ Warehouse AHUs: Replacement of 4 x R22 DX units with Chilled Water AHUs (Supplied by existing
ammonia chiller) 280kWR
⚫ R438A Drop-in refrigerant conversion for small capacity system
⚫ 8 x DX coils to be replaced with Glycol coils within various production equipment (Supplied by existing
ammonia chiller) Approx 600kWR
⚫ 7 other systems to be converted to either PGB or CHW
⚫ Future AHU and Ammonia Chiller installations planned
⚫ Similar Projects underway at Wahgunyah and Broadford sites
