Reliable quality standards at Heide Refinery
Heide Refinery is synonymous with outstanding quality standards in the industry. From efficient wastewater treatment to ISO certification, the company demonstrates its commitment to safety, environmental protection and excellence in all areas of its business.
Stringent quality requirements for the treatment of our waste
The wastewater from refinery processes is treated in a three-stage waste water treatment plant to ensure that the purified wastewater meets strict legal requirements. The purified wastewater is discharged into the North Sea via a twelve-kilometre pipeline.
Quality assurance through
long-term thinking and actions
We see ourselves as a transparent company with a willingness to constantly develop. We aim for reliable partnerships with our employees, customers and suppliers that are characterised by mutual respect and fairness.
Running a refinery means taking responsibility – for employees, for people, for the landscape of the region and, last but not least, for the sensible use of the raw material oil, which will become scarcer in the future. For this reason, we are an active partner in the relevant associations.
We belong to a total of 25 associations, including Wirtschaftsverband
Fuels und Energie e. V. and the umbrella organisation FuelsEurope, its European counterpart, as well as the district fire service association and the support group of the FH Westküste University of Applied Sciences.


Seamless quality management and adherence to high standards
The safety of people and the environment, high quality and information security standards, efficient energy management and climate protection are important to us and represent the guiding principles of our day-to-day work. Our certification in accordance with ISO standards 9001, 14001, 45001, 27001 and 50001 shows just how successful we are in this regard.
