Banana ripening plant – cooling/heating exchange
Each year, we ripen 23 000 tonnes of bananas at our banana ripening plant in Kaiseraugst, and this requires a lot of heat. At the same time, the bananas have to be cooled, so that they stay fresh. Both processes require a lot of energy. Having modernized the cooling system and replaced the old oil heating system with waste heat from the cooling systems, the banana ripening plant now saves 40 000 litres of heating oil each year, equating to a CO2 reduction of 115 tonnes. This enables CO2-neutral operations.
