Ledoga is one of Italy’s largest tannin producers and can be considered an intensive energy-consuming company. In fact, its electric and thermal energy consumption accounts for approximately 25% of its production costs. This led the company to install a 2.7-megawatt natural gas-fired cogeneration plant. The in-building plant is able to meet most of the company’s energy needs and is now running at about 95% of total capacity. The main advantages for Ledoga have been the reduction of CO₂ emissions by approximately 5000 tonnes/year and NOx and CO levels well below the regulatory limit.
