Printing and packaging industry from Japan's experience in energy conservation and emissions reduction

Although by simply replace the energy-saving lamps, replacement material can achieve a certain effect of energy conservation and emissions reduction, but to maximize energy savings, reduce waste, reduce wastewater emissions, is still a long-term system engineering.Especially for resource-poor countries, the energy is related to national security, therefore, energy conservation and emissions reduction is the only way for sustainable development in these countries.In this respect, the Japanese practice of printing and packaging industry has a good reference.

One, the complete system of energy conservation and emissions reduction

Japan's printing industry energy conservation and emissions reduction measures have a complete system.Energy saving can be divided into three levels, respectively is: careful use of energy, effective use of energy, efficient use of energy.

1, cautious use energy: refers to minimize waste, such as repair the leakage of pipeline, closed production equipment of the engine, to regulate the temperature of the air conditioning, etc.

2, effective use of energy: rely on some additional equipment, such as collection of boiler heat, drying oven for heat treatment, etc.

3, efficient use of energy, need the smooth transfer of the whole production process, if necessary, also need to upgrade some energy-saving equipment, such as cogeneration equipment cooling, thermal storage equipment and so on.

Through the comprehensive implementation of energy saving and emission reduction system, and constantly found throughout the production process, production environment unnecessary energy loss and waste emissions, put forward the solution, improve the production process.Energy conservation and emissions reduction is a management issue first, and then the technical problem.

Second, the energy saving from the pre-press design began

Prepress design is the first link of print production, the design of the right to reduce the energy consumption in the whole printing quality in the production process and waste emissions plays an important role.Japan in the prepress design, printing industry very pay attention to the effective communication with the customer, because this can reduce because of not fully understanding the customer demand caused by the repeated design;, on the other hand, will be timely communication with customers, to guide customers to compare various costs and environmental impact of subsequent processing need, choose the best design scheme, with customers to contribute to environmental protection.

With the strengthening of national limits on emissions, will no doubt make enterprise operating costs will increase accordingly.Only put the energy conservation and emissions reduction on the enterprises to improve production efficiency, reduce the production cost of a strategic height to implement, to achieve truly benign energy conservation and environmental protection, to achieve double return of enterprise benefit and social benefit.
