Natural refrigerants have replaced most ozone depleting substances
For nearly two decades, Nestlé has played a leadership role in developing and implementing sustainable, natural alternatives to ozone depleting substances for large scale industrial refrigeration, well ahead of the requirements imposed by the Montreal Protocol.
Since 1986 we have reduced emissions of ozone depleting substances per tonne of product by 99%. Currently we have 6 major investments in industrial refrigeration plants underway which will result in a further 80 tonnes of R22 being removed from our installations. Investment into these environmentally superior technologies currently stands at CHF 34.3 million.
Nestlé is now extending this experience to smaller, commercial refrigeration units and has started building and testing ice cream freezers with CO2 refrigeration systems. This natural substance fulfils most requirements expected from a modern refrigerant, and, unlike currently available solutions, it has a negligible impact on the environment and is inherently safe even under the most extreme conditions.
Natural Refrigerants
Nestlé has played a leadership role in developing and implementing sustainable alternatives to ozone depleting substances for large scale industrial refrigeration, well ahead of the requirements imposed by the Montreal Protocol. The Company’s program to replace CFCs and HCFCs by environmentally neutral ammonia and carbon dioxide in industrial installations started in 1986.

Industrial Refrigeration Improvement and Investment
Nestlé strives for continuous improvement in the technology and management of industrial refrigeration systems. Investment in natural refrigeration technologies is running at the level of CHF 34.3 million (200/), resulting in more than 80 tonnes of R22 being removed from industrial installations.
Small Commercial Refrigeration Units
Nestlé is extending its experience to smaller commercial refrigeration units and has started building and testing ice cream freezers with CO2 refrigeration systems. This natural substance fulfils most requirements expected from a modern refrigerant, but unlike other currently available alternatives, it has a negligible impact on the environment and is inherently safe, even under extreme operating conditions.
