Chr. Hansen - From waste to resource

At Chr. Hansen waste gets collected and recycled into new resources like never before. In just five years, the recycling rate of the secondary waste fractions has increased from 18% to 50%.


At Chr. Hansen's laboratories in Hørsholm and Avedøre also receive a weekly visit from Stena Recycling, who is passing by to collect, label and pick up hazardous waste. Here too, everything that can be recycled will be. Metal-containing hazardous waste such as spray cans, oil filters and batteries are sorted, pretreated and subsequently sent for recycling in either Denmark or Germany. Waste that cannot be recycled for new materials is burned at approved incineration plants and thus used for energy production. "When Stena Recycling collects and handles our hazardous waste, we know that it is labeled, handled and transported properly according to the law, and that safety is in place," Ninkie Bendtsen points out.


With a business strategy that bears the title of Nature's No. 1, it is not surprising that sustainable recycling is high on the agenda of the bioscience company Chr. Hansen. Over the past eight years, Chr. Hansen in Denmark collaborated with Stena Recycling to transform waste into new resources. The company's global goal is to reach a recycling rate of 40%. This goal has long been realized in Denmark, and in just five years the recycling rate has increased from 18% to 50% for the secondary waste fractions such as plastic, cardboard and metal. Chr. Hansen's primary waste stream is the so-called eluate (liquid residual fraction from centrifugation, etc.), which is disposed of for use in fertilizers and biogas plants.
