Investments for Climate Protection

Site-related integrated optimization programs can bundle measures and investments that reduce energy consumption in the long run and thus help protect the climate. Good examples are ECKART’s sustainability program at its Hartenstein and Wackersdorf sites, and the energy management projects of ELANTAS Europe at its Hamburg site and ACTEGA DS at its site in Bremen.

ECKART’s sustainability program, which runs over several years, contains around 50 improvement measures. Among them are a number of energy-related improvements, ranging from switching to LED technology for factory lighting to optimization of manufacturing plants, for example, the mills and screen washing units, as well as batch management and distillation.

Thanks to the measures implemented in 2015, the company reduced its energy consumption by 2,700 megawatts. That represents savings of 1,100 tons of CO2 emissions. With this development, the company has reached its goals in this area.

As a result of its ISO 50001 certification, at its Hamburg site ELANTAS developed a concept for energy optimization that consists of various technical measures. Apart from the conversion to LED technology and the installation of motion sensors for the lighting, a number of measures were implemented in production plants. Among other things, the pump used to pump heat-transfer oil into the production plants now operates intermittently. In addition, the pressure in the compressed air systems was reduced.

An employee campaign to save energy rounds out the package of measures. With it, the company explains to staff under which conditions motors and pumps become energy gobblers and encourages the employees to save energy.

In 2015, technical optimizations alone reduced CO2 emissions by 640 tons a year. With investments of around 75,000 euros, a total of 190,000 euros are saved each year.

At ACTEGA DS, ISO 50001 certification also forms the basis for the energy improvements that the company is making over several years until 2017. With the measures implemented in 2015 – including the optimization of cooling towers and pumps as well as compressors – the company reduced energy consumption by two percent compared to the previous year and thus achieved the goal it set itself.

Individual measures can also make a significant contribution to climate protection. This is evidenced by the optimization measure ECKART implemented at its U.S. site in Schererville. The new thermal post-combustion (TPC) of volatile organic substances (VOC) not only uses less primary energy, but also can reduce CO2 emissions by around 4,000 tons a year.
