GlassRepurpose, an international competition organised by Steklarna Hrastnik and the Museum of Architecture and Design

Glass is 100% recyclable and enables creative reuse


Glass is a sustainable and environmentally friendly material. With responsible use and reuse, it can significantly affect the preservation of natural resources.

Sustainability and corporate social responsibility in all fields of activity are among Steklarna Hrastnik’s key commitments, which is also confirmed by the company’s investments in the best available production technology in the transition to Industry 4.0, which will improve its energy efficiency and additionally reduce its ecological footprint.

Steklarna Hrastnik would like the business and general public to recognise the endless possibilities and opportunities offered by the reuse of glass and, in cooperation with the Museum of Architecture and Design and in the context of the BIO 26 Biennial of Design, they have organised the # GlassRepurpose competition.

The competition is aimed at architects, designers, photographers and anyone else interested in this topic. If you are interested in the competition and the terms and conditions of participation, you can read more about it at LINK.


“Steklarna Hrastnik is committed to the superior quality of the products coming from our glassworks, but not at the expense of the environment. Sustainability and corporate social responsibility to the environment and to people are included in all our business processes and decisions,” said Peter Čas, General Manager of Steklarna Hrastnik, on the occasion, adding that “various innovative projects and investments in the best available production technology in the transition to Industry 4.0 improve our energy efficiency and our ecological footprint. Creativity, boldness of thought and innovative approaches are what we want to see from the participants in the GlassRepurpose competition.”


Reducing the ecological footprint with new solutions

Steklarna Hrastnik’s commitment to responsible environmental actions is also evident from its indicators of sustainability. Investing in innovative solutions associated with the utilisation of waste heat, replacing fossil fuels with environmentally friendlier resources, increasing the utilisation of melting furnaces and other solutions have enabled the glassworks to reduce energy consumption per ton of melted glass by 10% in 2018 compared to 2017, while CO2 emissions were reduced by 6%, NOx emissions per ton of melted glass by 40%, and water use by 50%.


Together with its partners, the company is continually on the search for new solutions. The recently installed solar power plant will be connected to the hydrogen production plant – a part of a pilot device that will produce a pure, carbon-free source of energy – hydrogen. This will develop new technologies for melting glass using hydrogen and the resulting decarbonisation of fuel, which will consequently reduce Steklarna Hrastnik’s carbon footprint. They are also planning to install another 400 kW solar power plant, which will allow the glassworks to generate three percent of the electricity consumed in the plant.


The market of Steklarna Hrastnik is a global one, where sustainable companies and brands expect the same from their partners.
