Protecting the Climate with the Help of Energy Generation

Our companies work continuously on reducing their energy consumption, for this cuts costs as well as CO2 emissions.

Combined heat and power (CHP) is the focus of our efforts to modernize our plants for energy generation because it is especially efficient. In 2015, we not only installed a CHP unit at our site in Ascoli, Italy, but also undertook corresponding modernizations in Germany and pushed ahead planning for further such units. Three CHP plants are in operation Group-wide (Ascoli and Hartenstein).

In December of the year under review, ECKART began operating two gas-powered CHP units, each with an electrical performance of 499 kilowatts (kW), at its Hartenstein site. The volume of energy generated by the two units amounts to 7.5 gigawatt hours a year. As a result, the site can reduce its CO2 emissions by 1,100 tons a year. ECKART uses the waste heat of the generators for three different tasks. Nearly half serves as a heat source for distillation. The other half is used to heat buildings in the winter and for an absorption cooler in the summer.

At its Kempen site, BYK has largely completed its plans for building a new energy supply system. A gas-powered cogeneration unit will not only supply power for the site (performance: 50 kW). The company will also use the resulting waste heat generated (performance: 100 kW) for heating buildings and for generating process heat. In addition, the energy center will contain new compressed air systems that obtain part of the power from the cogeneration unit. The center is slated for completion by the end of 2016.

Independently of these developments, BYK commissioned a feasibility study to examine how else the company can harness renewable energies at all four of its German locations to help further reduce CO2 emissions. The results showed that the Kempen and Wesel-Emelsum sites would both be particularly suitable to achieve this goal. With a combination of photovoltaics and wind energy, around 3,500 and 5,500 tons of CO2 could be saved, respectively.
