Northeim, Germany -- ContiTech claims that converting its print-blanket production to calendered line rather than a coating process has enabled it to develop a climate-neutral process for making its printing blankets. The new process reduces by 70 percent CO2 emissions, and the remainder is being offset by a tree-planting project in the Central American state of Panama, ContiTech carries the climate-neutral printing blankets in its Conti-Air HC line-up under the Pure Printing label.
Conti said, "The calendering process used in making the printing blankets is chiefly responsible for the Conti-Air HC line's small carbon footprint. A steel roller forms the rubber into a slab of the requisite thickness. This is a much more energy-efficient approach than the conventional coating process. What is more, solvent additives can be dispensed with, so VOC (volatile organic compound) emissions are greatly reduced.
ContiTech Elastomer Coatings was the world's first manufacturer to have a life cycle assessment of its printing blankets drawn up and certified - in this case by Ostwestfalen-Lippe University of Applied Sciences under the direction of Dr. Manfred Sietz, professor, und Martin Komander, graduate engineer.
