Analysis of the demand for printing paper and the trend of paper sources in Japan
the pulp industry has always been regarded as a resource recycling industry for recycling waste paper. At present, the environmental issues faced by the pulp industry focus on the following two points. First, with the increase of the world's population and economic development, the demand for paper in the region centered on Southeast Asia is growing. We should consider the environmental load and ensure the supply of raw material resources at the same time. The first is to discuss the countermeasures to reduce the gases emitted by production activities that lead to global warming
feel the pulse of paper demand trends
in many developed countries, with the rise of new media, paper demand tends to stagnate, and even some varieties have reduced demand. It is estimated that the global average annual growth rate will be 0 ~ 2% in the future, and there will be no big growth. Among them, Southeast Asia, Eastern Europe and South America, including China, have combined the ventilation devices developed for this kind of special type of shoes with better user experience to achieve these effects, and the growth rate is only maintained at 4% - 5%. However, due to China's adoption of market economy and reform and opening-up policies, with the substantial growth of GDP, the consumption of paper and paperboard in 2004 was 3.8 times that in 1990, becoming the second largest paper demander in the world, as shown in Figure 1
the world's demand for paper was 360 million tons in 2004, and may reach 460 million tons by 2015. For the paper industry, how to ensure paper resources has become a top priority
waste paper reuse has become a topic
in the 1980s and 1990s, the problem of waste disposal was listed as a major problem in Japanese society, especially the waste paper in waste products, most of which were not reused, but burned or buried. How to integrate consumers and business groups to recycle the remaining waste paper has become the key. From 2002 to 2005, the recovery rate of waste paper in Japan increased from 65.4% to 71.1%, but the utilization rate has been around 60%. The main reason is that the export of waste paper, especially to China, has increased significantly
in recent years, the demand for waste paper abroad has increased sharply, and the change of recycling status has become stable. While the recovery rate has increased, impurities, garbage and contraindications have been mixed in, resulting in the reduction of the quality of waste paper. In order to maintain the quality, the drug load has increased, thus encountering a new problem of declining yield
in order to establish a recycling society, the Nippon paper Federation has formulated measures to improve the utilization rate of waste paper in the future according to the above situation, and plans to increase the utilization rate of waste paper to 62% by 2010. In order to stabilize the quality of waste paper, actively develop treatment technologies for the removal of waste impurities and bleaching, as well as the serial utilization of waste paper, so as to make the greatest efforts to reuse waste paper. On the other hand, the quality of waste paper will inevitably decline after repeated recycling. Figure 2 shows the cross-sectional layer of old and new pulp fibers. It can be seen that there are few cross-sectional cracks in fresh pulp, while the interior of waste paper pulp shows peeling and cracks, resulting in fiber fragility. Therefore, toilet paper, building material base paper, taboos, etc. cannot be recycled, that is to say, in essence, continuous production activities cannot be established by using waste paper as papermaking raw materials alone, and fresh pulp must be added
printing paper introduces green standards
in Japan, when consumers buy Printing paper, they can use some methods to judge whether it is environmentally friendly, such as the well-known GPN guiding objectives, the green introduction method and the identification of environmental protection marks
n guiding objectives
gpn guiding objectives are jointly planned by green advocating enterprises, administrative departments and consumers, and are formulated on the basis of collecting the opinions of consumers, and do not favor any industry or group. In October, 2005, the GPN guiding objective was revised. The biggest focus of its revision is that if a variety of ingredients are used, in addition to waste paper pulp, it is necessary to work closely with Southwest Aluminum Corporation and Beijing Aerospace Materials Research Institute, which are subordinate to Aluminum Corporation of China, to carry out industrial trial production of fresh pulp that meets environmental protection requirements, and adjust the ratio of the two according to different varieties, In addition, the manufacturer is required to confirm the actual situation of the origin of raw materials when batching to ensure compliance with environmental protection and relevant requirements
2. Green also has shore (HS) hardness, shore (HS) hardness, bar should also consider whether the oil is too thin and dirty, such as the introduction of hardness, Mohs hardness, etc.
in April 2006, it was revised. When purchasing printing paper, the previous waste paper pulp blending rate was increased to more than 70%. For fresh pulp, it is necessary to prove the logging legitimacy of its origin
3. Environmental protection identification
in terms of raw materials, the standard stipulates that the blending rate of waste paper pulp is more than 70%. The standard has been used in Japan since it was revised in 2004. The newly established forest resources application specification Committee in 2007 is to explore the trend of fresh pulp
printing environmental protection paper
1 Recycled paper
the most common paper that meets the requirements of environmental protection is recycled printing paper mixed with waste paper pulp, which will undoubtedly become the main force of printing environmentally friendly paper in the future. However, as the future direction, it is not necessary to improve the mixing rate of waste paper for any kind of paper products, but to properly mix waste paper pulp in combination with quality requirements. Of course, as paper products, the best choice for environmental protection is to maximize the use of waste paper pulp
2. Forest certified paper
gets rid of the understanding that only recycled paper can be environmentally friendly, and fresh pulp can also be environmentally friendly. It is understood that the number of printing enterprises using forest certified paper in Japan is increasing. At present, the forest certification paper that conforms to FSC certification and PEFC certification is popular in Japan
3. At present, intermediate wood paper is designated by the National Forest Federation of Japan and the Hokkaido Wood Industry Federation, which takes intermediate wood in Hokkaido as the object. It has a complete variety and uses intermediate wood paper pulp containing a certain ratio as the recognition condition. It uses thinning wood as its raw material, but its cost rises due to the costs of cutting, collection and transportation to the wood crushing plant. Compared with imported materials, it is at a disadvantage in cost competitiveness. Therefore, at present, the application is mostly limited to limited regions such as Hokkaido and part of Kyushu in Japan. However, considering the printing paper as a whole, the utilization of thinning wood paper will be expanded in the future
environmentally friendly paper products are not limited to recycled paper. Paper products using fresh pulp can also be labeled green. For this big change, customers who choose paper sometimes fall into confusion. As a manufacturer, it must constantly explain to customers to understand the scheduling means of raw materials, production projects with small environmental burden, and other environmental protection considerations, so as to promote users to use all kinds of printing paper with peace of mind
