Kreyenborg

What Kreyenborg does

Kreyenborg GmbH & Co. KG is a privately held, family-owned German plant engineering company founded in 1953 in Münster-Kinderhaus and headquartered in Senden, North Rhine-Westphalia, with 101–250 employees. The company designs and manufactures custom-engineered industrial equipment centered on its patented Infrared Rotary Drum (IRD) technology — short-wave infrared light drives moisture and heat from the inside out, enabling rapid heating, drying, crystallization, and decontamination of bulk materials in minutes rather than hours. Three product families anchor the business: IRD systems and variants (IR-CLEAN for rPET food-contact decontamination, IR-FRESH for odor reduction in recycled polyolefins, IR-BATCH for small batches, and FoodSafety-IRD for the food industry); a complementary range of mixers (MBM, USM), special silos, feeding systems, and big-bag stations; and the Kreyenborg Pelletizing Technologies (KPT) line of underwater pelletizing components and a newly launched aftermarket service pillar.

The company sells primarily through direct enterprise field sales with regional representatives and channel partners (Holmach Ltd. in the UK, GAEP in the Gulf region), supplemented by trial-center demonstrations in Senden and a heavy trade-fair presence (K Fair, FAKUMA, SIAL, NPE, Plastics Recycling Show Europe). Revenue derives from one-time capital equipment sales, aftermarket spare parts and service contracts, and process consulting/testing services; no public pricing is disclosed. Customers span plastics recyclers (e.g., Global PET in Brazil scaling to 4,500 tonnes/month food-grade rPET), organic food processors (e.g., Ziegler Organic), and specialty bulk material handlers, with operating geographies covering Germany, the broader EU, the UK, the Gulf, the USA, Brazil, Japan, China, South Africa, Vietnam, and Indonesia. The IR-CLEAN system received a positive EFSA Scientific Opinion in July 2025, validating >95% decontamination efficiency for food-contact rPET under EU Regulation 2022/1616, representing a material regulatory moat in a growing circular-economy application.

Core offering

Kreyenborg designs, manufactures, and services custom infrared processing systems (IRD - Infrared Rotary Drum) for heating, drying, crystallization, and decontamination of plastics and food products. The company also produces mixers, special silos, feeding systems, big-bag stations, and complete turn-key processing lines, and via its KPT division supplies underwater pelletizing components, spare parts, and retrofit services for the plastics, recycling, food, and bulk material industries.

Product overview

Kreyenborg is a German plant engineering company with over 70 years of experience, offering customized solutions for the plastics and food industries as well as other bulk materials. The product portfolio centers on infrared technology (IRD systems) for heating, drying, crystallization, and decontamination of materials. For plastics, key offerings include the IRD infrared rotary drum, IR-CLEAN® for rPET food contact decontamination (EFSA/USDA approved), IR-FRESH® for odor reduction, and IR-BATCH for small-batch processing, complemented by mixers, special silos, feeding systems, and turn-key solutions. For food applications, the FoodSafety-IRD enables sterilization, pasteurization, roasting, drying, coating, and stock protection using 100% electric infrared technology suitable for organic products. Under the KPT (Kreyenborg Pelletizing Technologies) brand, the company offers components for underwater pelletizing including die plates, blade holders, granulating blades, driving bushes, dryers, and perforated steel sheets. The company also provides retrofit, optimization, and aftermarket services including remote service, process consulting, and spare parts for installed systems. All products are manufactured in Germany (Senden, NRW).
