History

Dansk Olie Genbrugs refinery's history started at the port of Kalundborg in 1992. Mustad International Group saw the viability of turning the black waste oil into base oil "gold" and invested in a facility at the port of Kalundborg. It was already then essential to ensure access to raw materials, and during the 1990s, the former DOAK oil and Østjysk Olie Depot became part of Dansk Olie Genbrug A/S.

In the early years the waste oil was cleaned of heavy metals and made into a pure heating fuel oil, but the company continued to make efforts to produce recycled base oil for production of lubricating oils. New technology was developed and the production of base oil started 10 years later, in 2002.

As a full-scale trial facility, Dansk Olie Genbrug had to struggle with a number of challenges. The base oil production was a reality, but "teething troubles" and lack of sufficient waste oil deliveries still made stable production difficult.

In February 2005, production ceased temporarily. In the subsequent two years the ground was laid for greater reliability of supply of waste oil and production improvements were designed. The re-designs focused on energy saving and process optimisation.

In 2007, the run-up to improved production began, and production of base oil for new lubricating oils has since proved to be a reality. In mid-2008 a further refinement of the base oil was added, making it today completely comparable to virgin base oil.

Throughout all of these years, Dansk Olie Genbrug has provided its customers with the service of collecting their waste oil. During closure the re-refinable oils were stored and later refined into base oil.
