ContiTech Elastomer Coatings reports the results of a study to draw up a carbon footprint for printing blankets has shown that the production of ContiTech's printing blankets generates up to 70% less climatically detrimental CO2 emissions than world standard printing blankets. The University of East Westphalia-Lippe conducted the study.

"ContiTech AG is thus the innovation leader for environmental and climate protection in the field of printing blankets. With our products, we make a substantial contribution to climate-friendly printing," says Heiko Eymer, general manager of the Elastomer Coatings business unit, explaining the significance of the findings.

According to ContiTech, its calendering process in which the rubber is formed into a slab of the required thickness using steel rollers, eliminating solvents.

To determine the carbon footprint of the two printing blankets, Conti-Air Litho-HC and Phoenix Sapphire, the energy required for the entire manufacturing process was determined and converted into a comparative CO2 value. The production process uses primarily steam and electricity. The emission values for the raw materials used are also taken into account, from the extraction up to delivery to the plant, and for their pretreatment.

Based on this calculation, the coating process generates some 10 kg of CO2 per square meter. For the Conti-Air Litho-HC printing blanket, it was possible to reduce CO2 emissions by some 70% compared to the standard printing blanket, and by 35% for the Phoenix Sapphire. The scientific monitoring and certification of the CO2 footprint for printing blankets was carried out by the department of Environmental Engineering department at the University of East Westphalia-Lippe.
