One of the reasons for printing companies to focus on sustainable development issues is that customers require printing companies to implement environmental standards, pass EMAS (ecological management and audit program), carbon neutral printing or other green certification, otherwise printing companies will soon lose some Big customer. As a result, more and more printing companies have begun to “attack” the environmental management system, and through some measures to prove that they are environmentally conscious, on the one hand can stand out from the competition and can open up new business areas; When you promise to protect the environment, you don't have to "green" to cover up the truth. Although printing companies must consider cost-effectiveness in times of economic hardship, is there any measure to promote environmental protection while reducing costs? The answer is yes.
Managing energy efficiency
According to a survey by the German Print Media Association, the energy economy index (energy cost/enterprise total cost × 100) of the printing industry averages 2.3%. Of course, depending on the mode of production and the size of the company, there are also differences in the energy economic index: the energy economic index of large sheetfed printing enterprises is 3.5% higher than the average, and the energy economic index of large web printing enterprises is 6.4%. The small-scale web printing company has an energy economic index of 3.3%.
In fact, many printing companies have great potential for energy efficiency. On the one hand, with the development of technology, the environmental protection of advanced technologies that can be used in printing enterprises is also constantly improving, and the energy-saving efficiency is more obvious. On the other hand, the printing enterprise owners have rarely studied the technology and the environmental behavior of enterprises, but more research. Business objectives, in the new situation, they will change their thinking and pay more and more attention to energy management and conservation.
For example, printing companies can optimize the number of motor revolutions by optimizing compressed air equipment, optimizing air heating with high-efficiency air humidification, using new lighting technologies, lighting management, intelligent control and regulation technology, and peak load management and heat recovery. In this way, as long as the printing company has a certain number of printing presses and can carry out certain production shifts, it is possible that heating is no longer needed.
According to data surveyed by energy efficiency consultant Jürgen Bühler, printing companies with a scale of 3 to 250 people have an average energy saving potential of 25% based on kilowatt hours. Printing companies with more than 8 B3 size printing units can achieve energy savings of 29% to 45%, as these companies can save a lot in heating costs. Companies using thermoset web printing and thermal re-ignition equipment can achieve completely different energy efficiency through new technologies.
Energy efficiency management brings not only low-cost products, but also the potential of energy-saving enterprises. Energy-saving means that enterprises have a competitive advantage.
In addition, it must be mentioned that Jürgen Bühler believes that the energy consumption of the printing industry is not serious compared to other industries. Only web printing companies using dryers and companies with thermal re-ignition equipment are energy intensive. Type of business. It is convinced that the printing industry will make an important contribution to reducing energy consumption in the next few years.
Use environmentally friendly solvents
Printing companies have many options for practical measures that involve environmental protection and cost reduction. For example, many printing companies are still using harmful and environmentally unfriendly solvents. According to Jürgen Bühler, this makes the printing industry one of the industries with the largest emissions of VOCs due to the annual emission of large amounts of organic volatile compounds (VOCs).
In addition to the use of environmentally friendly solvents, the use of environmentally friendly solvents to reduce organic solvent emissions instead of direct emissions or combustion and the resulting energy savings are worthwhile for companies to protect resources.
Use environmentally friendly inks
Printing inks are increasingly being developed into environmentally friendly inks, such as vegetable inks made from rapeseed, flax or soybeans. This kind of ink does not require the use of solvent recovery equipment during use, which reduces waste generation and protects resources, so it is sustainable compared to traditional inks. Printing companies should avoid the use of heavy metal-containing inks, which not only benefits the environment, but also contributes to the physical and mental health of employees.
