Packaging firm Ardagh Group has announced that it has installed a heat recovery system in its glass production facility in Wahlstedt, Germany.
The initiative is part of the company’s efforts to ensure energy efficiency at its production sites.
The new system, which involves a preheater, is expected to reduce energy consumption at Wahlstedt by up to 20%.
The preheater allows unused 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.
The company’s chief sustainability officer, John Sadlier, commented, “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.”
Presently, Ardagh operates seven batch preheaters across its glass production facilities in Germany and The Netherlands.
