ALTANA Reaches Its Environmental Targets Worldwide

Energy-efficient management is a key component of ALTANA’s corporate strategy. Rising energy prices pose a risk to ALTANA in the face of climate change. We are continually working on reducing the energy consumption at all of our sites and in all areas. This not only concerns production, but also laboratory and administrative activities. Since 2007, we have measured our energy consumption based on the guidelines of the Greenhouse Gas Protocol, a standard that defines how companies should determine their climaterelevant emissions. 

 

We differentiate between CO2 emissions from direct and indirect energy consumption (oil and gas, Scope 1; and purchased electricity, Scope 2). In determining CO2 emissions, we work with data from the respective national electricity network and not from the respective supplier. We take the values for national grids from publications of the International Energy Agency. We set these data in relation to the gross value added and derive a key performance indicator from this.

 

 

Our goal is to reduce our CO2 emissions by 30 percent by 2020 compared to 2007. The corresponding target is 0.21. We have specified detailed sub-targets for each year. The target for 2013 was 0.24. With a value of 0.23, we even exceeded this goal, as the graphic shows.

 

 

The change ECKART made at its Güntersthal site in 2013 has played a key role in reducing CO2 emissions. Since then, we have used gas as a source of energy instead of oil. We laid a gas pipeline in the plant that supplies 18 boilers (and will supply 21 in the future). This cuts the CO2 emissions at the site by 16 percent, or 959 metric tons, vis-à-vis oil-based emissions.

 

The optimization of a machine park can also lead to a better energy yield and thus to improved energy efficiency. This is shown by examples from the U.S. and China. 

 

At its Tongling site, ELANTAS installed a new oven that uses less gas than its predecessor. ECKART can now produce pigments more efficiently in Zhuhai thanks to new filter technology. The motors for the nine new sieves require less energy than the old ones. Each year, around 110,000 kWh can be saved. In addition, the new plants are quieter, improving health protection.

 

In the U.S., ACTEGA Kelstar is now using new, energysaving electric motors. They replace the ecologically inefficient compressed air motors that have been used traditionally to ensure explosion protection in chemical plants.
