WASTE MANAGEMENT.
Waste is classified, stored, handled, transported
and disposed of in accordance with the applicable
legislation of the country in question. In this respect
Wintershall follows international and own standards.
Waste is classified into the categories “hazardous
waste” and “non-hazardous waste” according to
EU regulations.
In 2010 Wintershall incurred 61,268 tonnes of waste
(2009: 185,095). 29,505 tonnes were hazardous
waste (2009: 150,122) and 31,763 tonnes nonhazardous
waste (2009: 34,973).
83 % of the waste was disposed of at approved
dumps. Around 8 % was recycled or subjected to
thermal recovery, approximately 4 % was disposed
of in waste incinerators and 5 % was disposed of
properly in other ways. The volume of waste declined
in comparison to the previous year due to
completion of the recultivation at the used drilling
mud pit at Wietingsmoor.
WATER MANAGEMENT.
A total of 9.5 million cubic meters of water were
used in 2010 (2009: 9.8 million), most of which –

by production water. Some 6.55 million cubic meters
of production waster were reinjected into the reservoirs
after being separated from the crude oil and
natural gas at the surface. Production water from
our offshore platforms totaled 1.97 million m³ and,
