Clariant tries, wherever possible, to use recycled materials in production. However, the percentage is low due to the nature of the production process, as recycled raw materials cannot be used very often due to the requirements regarding purity or to maintain safety standards. Clariant uses almost only fresh raw materials from direct precursors for the reasons mentioned above. However, there is an internal cycle that is an integral part of the production process for auxiliaries, for product purification, and separation. The material in such recycle streams is used several times in order to deliver the desired energy and resource savings. A meaningful detection of the corresponding amounts is not possible as these cycles are an integral part of the overall process.
