150 years of BYK = 150 years of focus on innovation: We start our anniversary year with a success story in terms of sustainability. Our BYK production site in Shanghai has been equipped with a solar plant covering around 2,000 square meters. Even the parking spaces now supply solar power - and are shaded at the same time. Win-win, in other words. The solar plant supplies around 400,000 kWh of green electricity per year. If the same amount of electricity were generated using fossil fuels, this would result in carbon emissions of around 200 tons per year.
