Japan's Waste Paper Recycling Becomes an Example of World Environmental Protection

“Humanity is undergoing a new transformation of civilization. The rapidly developing Chinese economy is facing serious challenges. If it does not completely change the pattern of high-consumption economic growth, it is very difficult for China to exceed this threshold of civilized transformation.” Pan Yue, deputy director of the State Environmental Protection Administration This warning was issued at the "Green China" forum in the second sector. The impact of the printing and packaging industry on the environment cannot be ignored. Regardless of environmental changes or environmental changes, environmental protection will cause a profound change in the printing industry. There is still a long way to go before we can truly achieve green packaging and environmental protection. Let's take a look.

It is everyone's responsibility to protect the environment. Environmental protection has become a hot topic in recent years. In fact, this is not just a trend. Ecological scientists and scientists all over the world have already screamed to us through the results of their research. They pointed out that in the past four In the ten years, nearly half of the Earth’s forests, about 3 billion hectares have been felled, and the remaining 20% ​​have not been damaged by humans. According to statistics, there is only one large-scale virgin forest remaining in the world, and the number of trees has also increased. The fewer and fewer greenhouse gases in the world this year have caused the global temperature to rise. The U.S. and Canadians were affected more positively by this “heat wave” a few months ago. In the four seasons, the climate has become abnormal. I believe It is related to the reduction of the number. According to the actual development of the ecological environment and the continuous destruction of humanity, it is estimated that after 50 years, the icebergs of the north and south poles will be completely dissolved, the global water level will rise, and the low-lying areas will be flooded; all ecological balance will be Being seriously damaged, various facts tell us that we can no longer stay out of the way, but in addition to carrying out the mission of environmental protection in the context of personal life , To print the job, can make what action to protect the environment?

Printing pollution to the environment

As if printing is destined to harm the environment, start talking about it before printing! In the era of digital drafting, before printing, it was necessary to go through the process of printing, chemical printing, printing, etc. The chemical materials used therein often became the murderers of environmental pollution, and whether the used film or printing plate had a system. What about loop processing? When printing, the chemical substances in the ink, the washing water, and the noise all make a great deal of harm to the environment. What is more noteworthy is the problem of waste paper processing. It is only used as a printing plant, daily bad paper. What is the number of papers that are printed out more than paper for color testing? And all the waste paper, what will they do?

Printing and environmental protection

Since there will be so much pollution in the printing process, it seems impossible to promote environmental protection in the printing industry. However, this is not the case. Please take a look at Japan. Japan is a country that attaches great importance to environmental protection. Every year, there are Many environmental protection-related inventions, large and small, will also hold environmental protection exhibitions. At the same time, they will encourage their citizens to perform environmental protection duties in their lives, and "protecting resources" and "protecting the environment" have been listed as the development direction of corporate philosophy. one.

For the printing industry, environmental protection is the focus of their attention. The entire industry has continuously researched over the years how to reduce the damage to the ecological environment. They have already promoted environmental protection measures such as waterless printing and waste paper recycling, and invented many environmentally friendly printing products. In the most recent IGAS exhibition, they also exhibited inkjet systems and paper that can be repeated for printing. In Japan, many quality printing industries have passed inspections and obtained qualifications for environmental protection companies such as Dainippon Printing, Fujifilm, Toppan Printing, Nakagawa Printing, and Prince Paper. In addition to Japan, some foreign printer suppliers have also established their own environmental protection centers in foreign countries for research. If you say today that printing is contrary to environmental protection, I am afraid it is too outdated. On the contrary, we should cultivate a deeper sense of environmental protection to meet this environmental protection fever.

Waste paper recycling

Paper is one of the biggest wastes in the printing process. There are too many wasted papers for everyday bad paper and color paper. The most effective way to solve this problem is waste paper recycling. In Japan, they have one. The company that specializes in the recycling of waste paper for recycling consists of three companies: Sadada Corporation, Daiwa Bansoku Co., Ltd., and Daisan Industrial Co., Ltd. Among them, the Sadada Store has been engaged in waste paper recycling for three generations. The watchmakers in the industry; both Dahon Paper and Big Three Industrial are engaged in the business of paper making. Initially, the reason for their cooperation was that they had the same idea that if they could regenerate the waste generated, they could use it for their own sake. In the industry, environmental protection can save costs even more. Therefore, they cooperated hand in hand and formed the "DAIWA DAISAN GROUP", which specializes in waste paper recycling and recycling.

Waste paper recycling

They will first collect waste paper from various large and small printing plants, newspapers, and even households, and concentrate on the Sadaoda Store Co., Ltd. to regenerate them. First, the waste paper will be put into a washing machine that operates in a rotating washing machine. Inside, the waste paper is stirred into pulp, during which time the coarse material in the pulp is discharged through the bottom of the machine; then, the pulp is injected into the disintegrator and rotated at a high speed to isolate the fibers and add a low concentration of decomposition liquid. The fine particles still present in the screened pulp are further decomposed to ensure that the texture of the recycled paper is not too rough. Finally, a small amount of detergent is added to clean and water, and then the treated pulp is air-dried and becomes Materials that can be used for papermaking.

These materials are then sent to Daiwa Co., Ltd. and Daisan Industrial Co., Ltd. for processing to make reusable paper. Big Three Industrial supplies nearly 40 to 50 kinds of paper in Japan to meet the market demand and occupies a large market, and the head of the agency, Sada, said that the paper on recycled paper is always rough and difficult to obtain high prices. The market for paper products is, therefore, generally used in the printing of newspapers and magazines, but President Suda has stated that he has actively improved the quality of recycled paper, and he hopes to study more ways to minimize the particles in recycled paper. When the technology of waste paper recycling becomes more mature, it is believed that recycled paper will be able to enter the high-priced market.

In addition to the “DAIWA DAISAN GROUP” actively working on waste paper recycling, Prince Paper, which is familiar to Hong Kong and accounts for one-third of Japan’s paper product supply market, has also engaged in related work. In order to increase the quality of recycled paper, Prince Paper has added DIP waste paper deinking pulp equipment to increase the whiteness of recycled paper. In October of this year, Oji Paper also launched the “Hoxy nepia” series. The paper is made up of different percentages of recycled paper, 100% recycled paper, and 50% recycled paper, making it suitable for different customers. In addition, Oji Paper held the tree planting campaign, the “Oji Paper Environmental Protection Exhibition,” and set up a “forest museum” related to the paper industry and forestry. The contents of the exhibition included the types of trees, studies related to trees, and the environment. The relationship between greening techniques and paper and forestry shows that the company attaches great importance to environmental protection.

Waste paper recycling and use

According to the “DAIWA DAISAN GROUP”, the average monthly waste recovered from all over Japan is about 3,000 metric tons, mainly from newspapers, magazines, printing houses and processing plants, while the amount of residential recycling is only a small percentage. According to statistics, Japan's waste paper recycling rate was 61.0% in 2001, of which 24% came from newspapers, 27% from magazines, and the remaining 51% belonged to other papers, while the use rate of recycled paper reached 58%. Applied to newspapers, magazines, or general printing paper, there are also receipts for cartons, cartons, envelopes, cash dispensers, etc., and some of the high-quality paper recycled may be sold as toilet paper. .
