The full implementation of green printing costs

Once the "green printing" was launched, it has received widespread attention from insiders. Promoting the development of green printing is a mainstream trend in the printing industry. However, specific implementation requires the cooperation of upstream and downstream enterprises in the entire printing industry chain. Printing companies, while paying attention to the social responsibility and environmental protection significance of "green printing", must also consider the cost changes brought by "green printing", and invest additionally. They have made a preliminary summary of the main costs that printing companies need to invest in the implementation of green printing. , Mainly including the following aspects:

1. Comprehensive management of production environment

First of all, the discharge of pollutants from printing companies should meet the requirements of national or local pollutant discharge standards, which is also the most basic requirement of green printing. Waste water, waste gas, solid waste, noise, etc. generated in the production process all need to be collected or treated specially. For example, the purchase of waste gas collection and purification equipment in the workshop, noise isolation devices, developer, waste ink barrels, machine cloths and other hazardous wastes need to be recycled by a qualified environmental protection agency for disposal. After the treatment is completed, tens of thousands of yuan need to be invested every year to invite CMA-qualified testing institutions to conduct environmental testing on waste water, waste gas, noise and other projects.

2. Input of raw and auxiliary materials

According to the requirements of "Part 1 of Technical Requirements for Environmental Labeling Products Printing: Lithography (Draft for Comment)" issued by the Ministry of Environmental Protection, paper, ink, adhesives and other auxiliary materials have corresponding technical indicators. For example, printing paper must not add some plasticizers and heavy metals and their compounds, and the ink must meet the requirements of "HJ-T-2007 Environmental Labeling Product Technical Requirements Offset Ink". The price of these raw and auxiliary materials must be higher than ordinary raw materials. Environmentally friendly inks such as Tianjin Toyo Soybean Oil Offset Bright Quick-drying Ink have a market price of around 45 yuan / kg, and imported ones are around 100 yuan / kg. The ordinary domestic offset printing inks are mostly below 30 yuan / kg. In view of the small proportion of ink in the total cost of printing, this ink investment is not too difficult for printing companies. And in the future, it is highly likely to receive subsidies on environmental protection ink policies. In terms of adhesives, PUR adhesives are definitely more environmentally friendly than traditional EVA hot melt adhesives. At present, the price of EVA hot melt adhesives is about 25,000 yuan per ton. The price of a ton of PUR adhesives is more than 100,000 yuan, and the imported ones are 130,000 yuan. More than 70,000 domestically produced. Because the amount of PUR glue used in the same production is 2-3 times less than that of EVA glue, the real increase in the cost of introducing PUR glue lies in the equipment modification, that is, the purchase of special glue pots and supporting equipment for PUR glue, about 550,000 imported PUR glue pots, and It takes about 250,000.

3. Input in the production process

In order to avoid mutual pollution when using ordinary ink and environmentally friendly ink, stricter control is required for the cleaning of ink fountains and blankets. These require a lot of man-hours, resulting in excessive downtime and a decline in output per unit time. Like this, Indian companies will invest a lot of manpower and material resources in the production of environmentally friendly products. Production managers also need to pay more attention to and manage the production of these products.

4. Renovation cost of energy saving and water saving facilities

Resource conservation is a very important indicator for implementing green printing. These all need to invest a certain amount of money in the initial stage. But the benefits it produces will soon appear. In general printing companies, the annual water and electricity bills are not small expenses. So as long as the timing is right, this fund can be considered when investing.

Although the printing enterprises implement green printing from various aspects, we should also see that from the perspective of resource recovery and recycling, the economic benefits brought to enterprises are also very considerable. Moreover, as society's awareness of health and environmental protection increases, it will inevitably put more demands on the environmental quality of printed materials, which is also an undoubted trend. If a printing company implements green printing first, she must be more competitive and able to take on a wider range of living sources. And from a long-term strategic perspective, it is definitely a good thing for the present and benefit forever.

Due to the special nature of the industry, printing companies will be restricted by what kinds of raw and auxiliary materials and products they produce. Therefore, the implementation of green printing requires the joint efforts of the government, publishing industry, raw and auxiliary materials suppliers and the whole society . As an ordinary member of the printing circle, I also strongly urge the relevant state departments to introduce green printing support policies as soon as possible, so that the goal of green printing in China can be achieved faster and better.
