About Dohrn Trading
Dohrn Trading GmbH is a family-owned trading company for thermoplastic secondary plastics, founded in 1992 in Reinbek. The product range comprises regrind, regranulate, re-compounds and offgrade/NT material that can be used directly in typical applications of the plastics processing industry, for example in injection moulding, extrusion or deep-drawing processes. The material is delivered single-grade, clean, dry and free from contamination, and is tested in advance in the company's own plastics laboratory. Deliveries are made in various colours and in standard commercial packaging such as big bags and octabins on pallets. Since 2019, the company has also operated a business unit for technical spare parts for industry and shipping under the name D-Tech Spare Parts. Its markets include Germany, Europe and Asia; customers are served in their native language.
