The city of Wels stands front and centre in Austria’s energy revolution and has cultivated one of the strongest regional energy industries in all of Europe. Wels is an epicentre of major innovations such as liquid silicone processing and new standards in energy efficiency. Starlim-Sterner, known as the world’s largest liquid silicone processor, showcases how energy efficiency can serve as a competitive advantage in today’s industrial landscape. The partnership between Starlim and the traditional toolmaking company Sterner has been transformative. Operating from three locations in the Wels region, Starlim-Sterner manufactures over 5,000 different silicone products. These products, though often unnoticed in everyday life, play critical roles as car seals, dampers in kitchen drawers, and keyboard mats. Each year, more than 11 billion silicone parts are shipped from their headquarters in Marchtrenk to industrial customers across Europe, America, and Asia. Starlim's production process is a marvel of modern manufacturing, involving single and multi-material parts crafted from silicone through fully automatic injection molding. The company operates over 200 injection molding, compound, and 2K systems at its Marchtrenk and Weißkirchen locations, running production in shifts 24 hours a day, 365 days a year. The company's relentless pursuit of efficiency is a cornerstone of its strategy. Recognizing that flaws in control technology can lead to significant financial and energy losses, Starlim invests heavily in continuous improvement. Ventilation and cooling systems have also seen remarkable advancements. At one plant, the introduction of individually controlled ventilation systems slashed electricity consumption from 441 to 167 MWh per year, reducing related CO2 emissions by around 60%. Starlim’s approach demonstrates how industrial operations can significantly reduce their environmental impact while maintaining high levels of productivity and innovation. Starlim-Sterner not only leads in liquid silicone processing but also sets a benchmark for sustainable industrial practices.
