In the development of the production process and the office spaces, we assumed the highest possible energy efficiency (including high-quality insulation panels, LED lighting). Nevertheless, there is still a significant power consumption for production, cooling, heating, lighting, IT, controls, etc. That is why we thought it was important to generate this power responsibly. Since 2018, the entire roof of the production hall and offices are full of solar panels, which means that PolySto can run 100% on green, self-generated electricity. Employees use the charging installations for charging an electric car and bicycle. The surplus of green power production is injected back into the network and made available to other companies and users.
