Lehigh Technologies Announces Completion Of Micronized Rubber Powder Manufacturing Plant In Spain


Lehigh Technologies, a specialty chemicals company that produces sustainable raw materialsfrom end-of-life tires and post-industrial rubber, today announced that production has started at its new Murillo el Fruto Micronized Rubber Powder (MRP) plant in Navarra, Spain. The plant is the first for Lehigh Technologies outside of the United States and was constructed in partnership with Lehigh’s Spanish partner Hera Holding. The Murillo plant incorporates Lehigh’s proprietary cryogenic turbo mill technology and has the capacity to produce 10,000 metric tons of MRP a year. The plant will produce Lehigh’s PolyDyne™ and MicroDyne™ range of MRP, already used by customers in more than 18 countries around the world.

The production line is co-located with Indugarbi NFU, a leading tire recycler in Spain operated by HERA Holding, which will ensure efficient supply of granulate feedstock for the MRP manufacturing process. The construction of the Navarra plant was managed by Lehigh and executed by UK-based Jex Engineering, with support from the Dennis Group and Air Products. The plant was commissioned at the end of June 2018 and employs the same layout and equipment as Lehigh’s Tucker, Georgia plant in the U.S., ensuring consistent quality and products specification across all locations.

“I’m very proud of the international team that made this project successful,” said Jason Stravinski, Lehigh’s VP of Operations. “Engineers from Lehigh U.S., Lehigh Spain and Hera Holding all worked together with the Jex project team to complete the project on time and on budget. We expect this plant will be a crucial component to meeting the rising demand for green chemicals in Europe and beyond.”

The plant in Navarra will supply the growing demand for Lehigh’s MRP product range from the tire, bitumen, coatings, construction and polyurethane industries in Europe and the Middle East.

“Demand for Lehigh’s products is increasing rapidly and this new plant comes at the perfect time to support the growth,” said Lluís Molina, General Manager Lehigh Spain. “The Murillo plant is the next step in Lehigh’s mission to commercialize MRP for customers in a wide range of performance driven markets.”

Lehigh Technologies became a subsidiary of Michelin in late 2017. Lehigh is an important platform that supports Michelin’s recently announced goal that new tires will contain 80% of sustainable materials by 2048.
