Ardagh’s glass production facility in Wahlstedt, Germany has installed a batch preheater, or heat recovery system, which has reduced energy consumption by 20%.

The new preheater allows for waste heat from the melting process to recirculate and preheat a mix of raw materials and cullet to approximately 280°C which is then fed into the furnace for melting.

An E-filter cleanses emissions as they pass through.

“Ardagh continues to focus on sustainability and energy efficiency and this technology allows our facilities to achieve real energy reductions as well as cutting carbon emissions by up to 4,000 tonnes per annum,” said John Sadlier, Ardagh’s Chief Sustainability Officer.

Ardagh operates seven batch preheaters at its glass production facilities in Germany and The Netherlands
