Ardagh finds solution to weather impact on glass recycling

An energy efficient solution has been implemented by Ardagh gas to combat the problem of cold and wet cullet stored in outdoor bunkers during cold season. At the Nienburg plant in Germany, hot air is drawn at 80°C across the furnace, before it enters an heat exchanger that raises the temperature to 120°C. This hot air is then piped to the bunkers making the cullet ideal for remelt; annual energy savings of €116,000 have been achieved along with a CO2 reduction of 334 tonnes.
