Printing industry waste treatment

IV. Problems that Must Be Solved in the Waste Disposal System

It can be seen from the above that the establishment of a joint processing system for printing waste should first solve the following problems:

1. Printing industry waste name, quantity, origin, physical and chemical properties.

2. The current state of waste disposal in the printing industry and the difficulties encountered.

3. Participate in the cooperation model among the processing system operators.

4. Inspection, recycling, and discharge indicators after processing waste in the printing industry.

For these wastes, research and treatment recovery methods. According to the characteristics of the printing industry waste, it can be divided into the following aspects:

1. Disposal of waste inks, specifically for the recovery and disposal of waste inks and ink tanks.

2. Wastewater treatment, specifically dealing with waste developer and waste water discharge and recycling issues.

3. Solvent recovery, specifically for solvent recovery and disposal.

4. The machine wipes cloth and ink waste rags to handle the cleaning and destruction of rags.

5. Waste paper processing, special treatment of waste paper recycling and disposal

While establishing a project for the joint processing of printing waste, it is also necessary to focus on technological research and development in the following two aspects:

1. Development and use of printing environmental protection new materials

The printing industry is strongly encouraged to use non-polluting or low-pollution industrial production technologies to change the structure of raw materials and printed products in order to avoid waste. When printing companies produce prints, they should improve their printing methods and process flow, and ultimately reduce pollution.

2. Recycling of printed waste

In the printing waste, we actively seek out the targets that can be recycled, including the direct recycling in the factory, and then used in the production line or provided to other factories as raw materials. For example: recycled paper, recycled plates, etc.

V. Actively promote the printing industry waste joint treatment system

1. The state supports economic and policy support

1 Actively provide incentives such as financing loans, environmental protection fund grants and tax reductions to encourage the industry; 2 study passive punitive measures such as pollution discharge fees and pollution deposits to accelerate the determination of the industry.

2. National scientific research institutes give technical support and guidance

Provides technical guidance for the printing industry's waste reduction technologies and treatment plants, helping the printing industry to effectively dispose of waste.

3. Establish a publicity system for the joint processing system of printing waste

The printing industry and associations should actively publicize their reports and entrust the National Printing Industry Association with the promotion and communication of various manufacturers, convening seminars and conferences. For difficulties encountered, it should be actively eliminated.

4. Solve the difficult problem of waste disposal

As for the disposal of waste, there are still many technical and practical difficulties. Just like the ink tanks, the brands and the brands are different. Therefore, the same steps and recycling conditions cannot be used for disposal. It adds many unpredictable factors to the actual operation. The only way is to propose a solution as soon as possible, and make an overall plan for packaging, size, and disposal methods, and establish feasible recycling and disposal conditions.
5. Solve the financial difficulties

The combined waste printing and waste disposal system requires a large amount of funds, and most of the printing plants are small and medium-sized enterprises, which require several companies to jointly seek financial support from the banks and the government while the relative funds increase.

6. Actively improve the printing industry's own environmental awareness

China's printing companies have long been passively accepting the role of environmental awareness. Over time, they have become indifferent to, and indifferent to, environmental protection. They have not kept pace. More importantly, various manufacturers may not be able to thoroughly understand the prospects of establishing a joint waste printing waste disposal system. Therefore, it is necessary to cooperate with the state and industry associations to strengthen the guidance and promotion and improve the old concepts of traditional printing factories.

China has joined the WTO and the high environmental protection requirements of the international environment must improve the environmental awareness of printing companies. Market competition is not only the product quality, price, and service, but also the environmental factors of printing companies, employees' environmental awareness, and the initiative and consciousness of protecting the environment.
7. Printing companies should turn from the method of solving the problem at the technical level only to the management level, change the handling method of past improvement, and turn it into prevention in advance so that the pollution from printing operations can be reduced to the minimum and comply with the trend of international environmental protection. Printing companies actively promote the ISO14001 environmental management system.

8. The universities and research institutes that set up the printing engineering profession in China should strengthen the education and training of research on waste disposal in the printing industry and related professional knowledge, so as to raise the awareness of environmental protection and environmental protection methods of senior professional printing and technical personnel to a new height.
