SOLIDA has been using its own combined heat and power plant for four years now. It improves energy efficiency by generating electrical energy and heat. In this way, around 100,000 kilowatt hours flow into the company's own requirements every year. The modernized heating system thus reduces the inflow of external electricity and has made a significant contribution to reducing the company's gas consumption over the past four years - an immense relief for the environment. On the basis of an internal energy recording system, SOLIDA is continuously working on further implementing environmentally friendly alternatives.
