Environmental management systems to ISO 14001 are in place at all Heidelberg production and development sites in Germany, with the aim of further improving the company's environmental performance. Trained environmental officers ensure compliance with the relevant environmental protection standards, identify areas where there is potential for improvement, and promote the use of efficient technologies.
The goals achieved and implemented thus far are impressive. For example, improvements introduced to the workflows and process parameters at the final approval stage for 70 x 100 press production at the Wiesloch-Walldorf site have cut paper consumption by around 30 percent in the last four years.
In addition, a new method for analyzing and releasing press testing paper has also cut paper consumption for this test by 94 percent.
A new cleaning chemical used since mid-2009 in the pretreatment of liquid coatings in Wiesloch-Walldorf gives rise to significant energy savings, enabling the bath temperature to be reduced from 60°C to room temperature and allowing the bath heating to be switched off. This saves 1,000 MWh of heating energy per year, which is equivalent to around 260 metric tons of CO2 if the heating is powered by gas.
Energy savings have also been implemented at the Amstetten site, which is home to the company's foundry. Since 2009, innovative technologies installed in the mechanical production facility make it possible to adapt the ventilation and air-conditioning equipment to the actual demand. This saves 3,500 MWh of energy a year, equivalent to around 1,150 metric tons of CO2 emissions based on the site's energy mix. As of 2010, the cold water used to cool the foundry is generated from waste heat, which saves a further 1,850 MWh of energy and approximately 630 metric tons of CO2 emissions.
Heidelberg pursues a green fleet policy, which sets an upper limit for the CO2 consumption of company cars. So far, around 200 company cars have been switched to more environmentally friendly models, thus lowering CO2 emissions by around 100 metric tons.
Entries to the Heidelberg ECO Printing Award for sheetfed offset print shops can be submitted till the end of February 2011 in the categories "Most sustainable print shop" and "Most innovative stand-alone solution". Being presented for the second time, this international award is designed to encourage the environmental commitment of Heidelberg customers.
