Oleochemicals (bio-based chemicals) are derived from plant and animal fats. They are analogous to petrochemicals derived from petroleum, and are an important product flow handled by Koole especially in Rotterdam (Pernis) but also in Nijmegen and Zaandam.
Oleochemicals often require heated stainless steel tanks. The batch sizes are relatively small; the products are stored in tanks varying in size from 350 to 4,000 cubic metres. Substantial volumes are imported from South East Asia via seagoing vessels and are loaded into tanker trucks for inland transportation. Koole is a major player in this business.
