Hartenstein additionally generates electricity from a hydroelectric
generator, and BYK in Denekamp deploys biogas
to generate energy. In total, ALTANA already generates and
uses around 2,840 MWh / year from renewable energies.
In the year under review, ALTANA also compensated for
33,351 tons of greenhouse gas emissions from the hither-
to unavoidable use of natural gas by financing equivalent
climate protection projects in the regions where the greenhouse
gas emissions occur.
Responsible Usage of the Resource Water
Water plays an important role in many of the ALTANA Group’s
production processes, and so the specialty chemicals group
is making various efforts to use this resource sparingly. Water
is used in the chemical industry as a raw material, as a
cleaning agent, and as a coolant. ALTANA aims to keep its
water consumption as low as possible and to use water
as a cooling medium in closed loop systems.
In the year under review, we were able to significantly
reduce water consumption at several sites. Through opti-
mization measures, ELANTAS reduced consumption of city

of all sites, a roadmap with concrete projects was drawn
up to achieve a complete energy transformation. The implementation
of the projects is ensured by the appointment
of corresponding teams. ACTEGA North America is evaluating
options to replace the currently existing natural gas
burners with electric ones. ACTEGA’s site in Spain converted
to a CO²-neutral heating / cooling system. And of course
ALTANA also pays attention to the seemingly minor things
when it comes to energy transformation. In 2021, for example,
diesel- and gas-powered forklifts were replaced by
electrically powered ones at various sites. In cases where
sites cannot currently obtain certified green electricity directly
from the local electricity provider, so-called Guarantees of
Origin for electricity from renewable sources are purchased in
accordance with recognized quality standards (for example,
CoO for Europe, IREC for China, and GREEN-E for the U.S.).
In 2021, the volume was approximately 263,455 MWh.
In parallel, ALTANA is working intensively on further possibilities,
for example direct procurement from sustainable
energy generation plants. Some ALTANA sites already generate
their own energy from renewable sources. ELANTAS
operates its own photovoltaic systems in Ascoli, Collecchio,
and Pune, and at BYK’s site in Deventer. ECKART in
