Glass production is an energy intensive process, where fossil energy, necessary for the melting process, is emitted to the atmosphere.

To reach climate protection targets and reduce energy costs, the glass industry is striving for an energy efficient glass production process.

The aim is to optimise the glass production process in a way that reduces energy consumption as much as possible.

The industry has optimised many process steps regarding but in the area of the rejected heat by the waste gases there is still plenty of thermal energy, which ends up unused in the atmosphere.

The solution

Zippe works in the field of batch preparation and cullet handling, among other things. It built its first batch preheaters several years ago with a high recycling cullet portion and sold them successfully.

It has developed its preheating technology and adapted it to the different batch formulas of the single glass types thanks to its collected experience. Preheaters that run independently from the cullet portion are also now available.

For the operator of a production process it is necessary to follow-up the process steps integrally, starting with the entrance of the raw material up to the outgoing of the final product and to optimise the corresponding processes in a way that a maximum of productivity is reached with the least effort regarding raw materials and waste material.

Therefore Zippe always observes the whole process in its field of activity in the glass industry and tries to plan the different cycles energy efficient, low-maintenance and this inexpensive for the operator.

The advantages of batch preheating are:Reduction of emissions (CO2 and NOx), increased energy efficiency and increased plant productivity.
