Since 1971, the idea of Economy equals ecology has always been a concept defended at all costs by the founder Romano Minozzi. Renewable energy would have grown to become an essential part in environmental projects towards sustainability. Iris Group’s production plants have implemented solutions for energy saving, minimum environmental impact, best practices in air emission and water pollution. For example, in the Porcelaingres plant in Vetschau, a 2.4 MWp photovoltaic plant is active, one of the largest renewable energy plants in Germany. An indoor area of 50,000 square meters with a photovoltaic power plant installed on its roof, in order to keep monitored and restrict CO2 emissions by more than 2,000 tons per year, equal to the annual CO2 emission of about 900 cars.
