China is a country with very scarce forest resources, and its per capita forest area is only 1.128 hectares, which is only 21.3% of the world's per capita. The national per capita forest stock is 9.15 cubic meters, which is only equivalent to 1.2.6% of the world's per capita stock. At the same time, China is a big timber consuming country. At present, the domestic timber demand is about 311 million cubic meters every year. According to the consumption data of our country over the years, the domestic timber supply can only be about 231 million cubic meters at the maximum. When the timber supply gap is between 1.7-1 billion cubic meters, this gap between supply and demand will be filled by imported timber.

According to statistics, in recent years, China's imported wood has consumed 7-8 billion US dollars in foreign exchange each year (excluding pulp and paper products), and it has become the third largest household after imported oil and primary plastics. If this rate continues to increase, in three or five years, wood import and use of foreign exchange will become the top foreign trade company in China, which will have a great impact on China's international balance of payments. However, with the sustained economic development and the continuous improvement of people's living standards in China, the demand for wood will only increase day by day. In order to meet this demand, we should not rely on imported wood for a long time, but also build a large number of fast-growing and high-yield forests and strengthen wood conservation and substitution. The former can be described as open source, while the latter focuses on throttling. According to the phenomenon of a large amount of wood waste in many fields in China and the poor access to wood recycling, it is particularly important to strengthen wood conservation.

since the reform and opening up, the pace of urban modernization has accelerated, urban infrastructure has developed rapidly, and decoration, tourism, transportation, communication, furniture, exhibition, catering and sports have flourished. All these undertakings have always constituted the demand for wood and its products, and at the same time, they have also produced a lot of wood waste. One of the main characteristics of this kind of waste is that most of it is leftover materials, daily necessities or packaging and decoration materials after wood processing. They are treated as garbage in a scattered and neglected state. However, China is a big country with a population of more than one billion, and the amount of waste wood is extremely amazing. Over time, these recyclable wood resources are lost in vain, which is a huge waste.

1. Categories and quantities of wood waste in China at present

Below, we only roughly divide these wood wastes into three categories, and make rough statistics as much as possible, so we can clearly see that these wood waste materials, which are usually ignored by people, are either a waste or a crime if they are not put on the road of recycling economy as soon as possible.

(1) Paper:

China produces about 21 million tons of waste paper every year. For every 1 tons of waste paper recovered, 811 kilograms of paper can be made again, saving 3 cubic meters of wood. In other words, if we can recycle most of the waste paper every year, we can reduce the felling of hundreds of millions of trees.

It is worth noting that the recycling of waste paper in China has made rapid progress in recent years. Statistics in 2113 show that the recovery rate of waste paper in China reached 31.6%. Of course, we can also see that the potential of this cause is still great.

(2), daily necessities:

1, wooden chopsticks: According to statistics, there are thousands of wooden chopsticks production enterprises in China, which produce about 11 million boxes of wooden chopsticks every year, consuming 5 million cubic meters of wood resources every year. The annual output of commercial wood in China is less than 51 million cubic meters, of which wooden chopsticks materials account for 11.5%. A 21-year-old tree can only make about 3,111-4,111 pairs of chopsticks, so 25 million trees need to be cut down every year.

2. toothpicks: It is reported that more than 6,111 toothpicks are consumed every year in China. If it is made of wood, it needs 1.6 million cubic meters, equivalent to 2.13 million mu of trees.

3. Ice-cream stick: According to statistics, by the end of last year, there were more than 3,111 enterprises producing cold drinks in China. Only making ice cream and popsicles requires about 1 million cubic meters of wood every year, and consumes about 5 million trees with a diameter of more than 11 cm.

4. Packaging boxes for shirts and moon cakes: It is estimated that 1.2 billion shirts are sold on the market in China every year, and the paper consumption for packaging boxes alone is as high as 241,111 tons, which is equivalent to cutting down 1.68 million big trees with wide bowls. China produces 11 million boxes of moon cakes every year, and the packaging costs 2.5 billion yuan; The consumption of wood is about 811,111 cubic meters, and 4 million trees are needed.

5. Greeting cards: It is understood that more than 1 billion greeting cards are consumed in Christmas, New Year's Day and Spring Festival every year. Every million greeting cards are produced, 5.5 cubic meters of wood is consumed, which means that every 4,111 greeting cards are produced, the wood consumed is equivalent to a big tree. After three festivals every year, the fate of most greeting cards in the country will become abandoned, which is equivalent to cutting down more than 21 thousand 11-year-old trees.

(3), urban wood waste

Different from the above two types of wood waste, this part of wood waste directly appears in the form of wood tangible solid, with a huge number and a rapid growth rate. The recycling of this waste is the most lagging behind.

This kind of wood waste can be divided into three categories according to its source:

First, production and construction items:

1. In recent years, China's wood furniture, wood-based panels, wood processing and various wood products manufacturing industries have developed rapidly, and a large number of processing wastes will be produced at any time.

2. Abandoned wooden tools after construction abandoned by various capital construction projects, such as templates, springboards, pads, crowbars, scaffolding, lintels and various wood-based panels.

3. In the process of urban renewal and house demolition, the wooden components of buildings, such as doors and windows, floors, beams, columns, purlins, rafters, floors, escalators, barriers, etc.

4. Discarded wood products in industries such as industrial products, logistics storage, conferences and exhibitions, department stores, etc., such as wooden packing boxes, pads, shelves, billboards, cables and wires, and a large number of exhibition brochures, sample publicity materials, contract texts, etc.

Second, military, sports and education items:

1. Gun handles, gun butts, wooden bridges, baffles and other wooden articles for training that have been eliminated by urban garrison, public security armed police and firefighting forces.

2. All kinds of wooden sports equipment eliminated by sports teams and colleges at all levels.

3. Every year, schools and kindergartens replace the old ones with the new ones to eliminate the desks, chairs and beds.

Third, the renovation of rooms and the renovation of furniture:

1. The upsurge of indoor decoration in cities and towns, which has lasted for many years, will produce a large number of wooden waste items every day, such as all kinds of wood-based panels, floors, battens, Fang and other scraps.

2. Old wooden furniture and various wood products discarded by enterprises, institutions and households in the process of upgrading office and living room furniture, such as wooden beds, tables, chairs, cabinets and so on.

Fourth, urban greening:

Every year, trees that are not suitable for urban cultivation, old, sick, withered and decayed trees, and a large number of pruning branches are eliminated in the process of urban landscaping. Take Shanghai as an example, only 311,111 street trees can produce 5,111 tons of pruning after winter pruning every year. Taking Beijing as an example, in the spring of 2114 alone, a "over-ripe forest reconstruction project" implemented by the urban greening and garden department of Beijing eliminated 1.5 million mu and 1 million female poplars with flying catkins and replaced them with pine, cypress and locust trees.

The above rough statistics about wood waste in cities and towns in China are not alarmist, and the main purpose of this paper is not to advocate refusing to use wood. Because not using or using less wood is bound to vigorously seek substitutes, such as steel, plastic, cement and so on, and these materials are non-renewable. Replacing renewable resources with non-renewable resources is not consistent with the concept of circular economy, not to mention the latter is also a scarce resource for China. Therefore, what we emphasize is that China is a country with a large population. If every cubic meter of wood is fully recycled and reused, it will become a huge resource wealth, which is equivalent to protecting and saving forest resources. We don't agree to stop the manufacture, sale and use of disposable wood products in a general way. The key is that the above-mentioned series of wood products can't be easily thrown away after being used, making it become landfill garbage. Instead, we should quickly establish a recycling channel for them to achieve the purpose of repeated recycling. The benefits of doing so are obvious.

second, what is the significance of quickly establishing a recycling channel for urban wood waste?

(1) once the benign channel of recycling wood waste in cities and towns in China is smooth, it is estimated that only 31% of the recycling amount in the initial stage of operation (of which the recycling rate of waste paper in China has reached 31.6% at present) can save about 12 million cubic meters of wood for the country. If it is increased year by year after that, in time, 61-75% of wood waste can be returned and used. That is, the so-called wood waste has become a historical concept. On that day, wood reuse alone can save about 81 million cubic meters of wood for the country. The prospects are considerable.

(2) China now imports wood and its products from abroad every year, equivalent to an actual volume of about 1.2 billion cubic meters, with a value of 7-8 billion US dollars. If China implements the basic recycling of wood waste, it can save the country about 2 billion dollars in foreign exchange.

(3) China is a country lacking in forest resources. Theoretically speaking, if China recycles wood waste materials to the maximum extent, it is equivalent to creating "hidden forests" one after another in a short period of time, that is, in two years, a Daxinganling forest region can be rebuilt.

(4) wood recycling can also save the cost of garbage disposal and a lot of energy for the country.

(5) Improper disposal of urban wood waste will cause serious consequences, such as piling up and burning will produce a lot of harmful gases such as formaldehyde, which will endanger people's health. Wood recycling is not only beneficial to urban environmental sanitation, but also can improve the ecological environment of urban and rural areas, which can be described as killing two birds with one stone.

(6) The recycling of waste wood products promotes the technological progress of industrial production, promotes the reform of economic structure, is conducive to industry integration and enterprise innovation, and can also provide a large number of jobs for the society.

Third, it has become an urgent and imperative task to establish a recycling channel for wood waste materials.

From the current international resource supply situation, national policies, public opinion and the requirements of the broad masses of the people, it has become an urgent and imperative task to establish a recycling channel for wood waste materials as soon as possible.

(1) globally, wood resources have become increasingly scarce. Moreover, the voice of international environmental protection is growing, and many timber producing and exporting countries have formulated policies to prohibit or restrict timber harvesting and export. Obviously, this trend should be paid great attention to for a country like China, which depends on imported wood to a great extent, and it is necessary to make preparations as soon as possible.

(2) The central government has established a comprehensive, coordinated and sustainable Scientific Outlook on Development that adheres to people-oriented, and has repeatedly stressed that resource conservation and environmental protection should be placed in an important strategic position, and the development system of circular economy should be improved as soon as possible. Relevant departments of the state have also indicated that it is necessary to ensure the establishment of a circular economy system suitable for China's national conditions through legislation, and clearly put forward that all kinds of waste resources should be vigorously recovered and recycled in the process of generating renewable resources. Recently, the National Center for Wood Conservation and Development, the competent department of wood conservation and development, clearly put forward that it is necessary to focus on technical research and demonstration work such as the utilization of "three wastes", wood protection and recycling of waste wood.

(3) At present, local governments in some areas of China attach great importance to the recycling of waste wood materials, and have begun to reuse waste wood raw materials, save local resources, develop local wood processing industry and protect local ecological environment as an important measure. Some local governments have also formulated a series of preferential policies for this purpose.

(4) The broad masses of people in our country have the consciousness, habit and tradition of saving wood and making full use of old materials. That is to say, there is a broad mass base for promoting the reuse of waste wood in China.

(5) Since liberation, China has done a lot of work in wood conservation and substitution, and achieved remarkable results. Statistics show that during the period from the Sixth Five-Year Plan to the Ninth Five-Year Plan, China has saved a total of 11,556,611 cubic meters of wood through centralized recycling, processing and utilization of wooden packaging such as glass and bicycles, as well as waste pit wood, sleepers, poles, furniture and dismantled wood for building construction. Thus, it provides valuable experience and operational methods for further recycling and utilization of waste wood.

(6) With the implementation of the "zero tariff" policy on wood imports in China, a large number of overseas wood resources have flooded into the country, and at the same time, the advanced experience and practices of recycling waste wood in many developed countries have also made people feel refreshed. For example, Germany, Finland, Sweden, the United States and our neighbor Japan all have a set of effective recycling procedures in this regard, which are guaranteed by strict laws and regulations and accompanied by strict management and supervision means. For example, last year in Germany, a management decree on waste wood recycling was promulgated, that is, the national wood was recycled by waste recycling companies and classified. One or two kinds of waste wood are sold to processing plants for reuse and made into fiberboard, chip board and various furniture; Three or four types of waste wood are sold to power plants as industrial fuels for boiler power generation. On the basis of learning the advanced experience of developed countries, we can establish a channel for recycling waste wood suitable for China's national conditions. It is reported that some equipment suppliers from developed countries have started to do business in China and made some progress. For example, Kangbai Company in Britain, diefenbach Company and Meyer Company in Germany, and AFS Company in the Netherlands are all exploring in some economically developed areas in China. This will undoubtedly play a positive role in promoting the recovery and utilization of all kinds of waste wood in China.

(7) From the characteristics of waste wood itself, it can be said that all abandoned wastes in the city are the most direct, simple and easy to recycle. In addition to waste paper and ordinary daily life wood items, a large number of urban waste wood items in China are good in quality, which is better than similar international items. Waste wood is solid, light in weight, clean, easy to sort, convenient to transport and suitable for processing. In China, waste wood can be used to process and produce wood-based panels. Wood-based panels can replace solid wood in many applications. Each cubic meter of wood-based panel can replace 3 cubic meters of logs, while the production of 1 cubic meters of wood-based panel only needs about 1.5 cubic meters of wood raw materials. Therefore, it is one of the most effective ways to make full use of the huge amount of waste wood produced in cities and towns every day to develop China's wood-based panel industry.

to sum up, with the sustained development of China's economy and the continuous advancement of urbanization, the time is ripe for the industrialization of recycling and recycling of all kinds of waste wood resources. This work is beneficial to the people, and its contribution will be in the future. We must never take it lightly again.
