Stoelzle Oberglas in Köflach: Sustainable glass production with a future

Köflach. The focus of Stoelzle Oberglas is the sustainable production of packaging glasses, which are in demand in a variety of industries. The company in Köflach has been producing more than three billion vials every year since 1871. With over 500 employees and up to 20 new apprentices per year, Stoelzle is committed to promoting innovative technologies in order to significantly reduce energy consumption and the CO _{2 emissions.}

The glass factory relies on modern research and development methods. In order to achieve the long-term goal of climate neutrality by 2050, the company is planning to reduce the CO _{2 emissions by half by 2030. The central measures here are the use of recycled glass, i.e. shards, and the use of alternative raw materials. In addition, the weight of the glasses is reduced by the development of lightweight glasses, which also contributes to minimizing the energy requirement.}

innovations for more efficiency

An example of the innovative approach of Stoelzle is the newly installed mixture warmer. This technology uses the waste heat from the melt tanks to preheat and dry the raw materials from which the glass is produced. This leads to an energy saving of over 8 percent in the melting process and reduces the annual energy consumption by around 4,000 MWh.

The existing energy self-sufficient is supported by photovoltaic panels, which generate around 3,200 MWh of green energy annually. These surpluses are fed into the local energy network, which further underlines the sustainable orientation of the company.
