With ever increasing recycling targets to meet, manufacturers of glass bottles and jars need to make sure that they can feed their furnaces with the highest quality of cullet (recycled glass) and maximise the energy and carbon saving benefits that this offers.
>”[…]When it is delivered to the glass plant, cullet is typically stored in outdoor bunkers, where it is subject to variations in the climate, particularly during winter months. If it has accumulated significant levels of water, snow and ice, it will require higher temperatures, and thus more energy, to remelt it in the furnace.
The task facing the operations team at Ardagh’s Nienburg plant in Germany was to find a simple and environmentally effective solution. The obvious approach is to pre-heat the “frozen” cullet prior to feeding it into the furnace. But because a traditional preconditioning process can use a lot of energy, an alternative approach…
