The Copenhagen World Climate Conference that was held not long ago has come to an end. Although no substantive resolutions have been formed, the low-carbon economy has undoubtedly become an inevitable choice for governments in dealing with the major contradiction between the global climate crisis and the development of the world economy. The low-carbon model has also become an important consideration in the transformation of China's economic development model and industrial restructuring. As an indispensable supporting industry in the sustainable development of China's national economy, the packaging industry naturally must adapt to the international trend and strive to change the traditional path and quickly transition to a low-carbon model.
Analysis of Green Packaging Materials and Carbon Footprint
Zhang Yaoquan, president of the Zhejiang Packaging Technology Association pointed out that after more than 30 years of reform and opening up, China's packaging industry has become a full range of products, complete systems, and high levels of industrial relevance in terms of industry scale, growth rate, and market capacity. One of the industries. Zhuang Yingjie, chairman of the Shanghai Packaging Technology Association, believes that the packaging industry is facing the impact of the third wave. Because the packaging industry is one of the most expensive consumers with the largest number of resources and the largest number of resources, its development will increasingly be constrained by resources and the environment. Therefore, how to promote the structural adjustment of the packaging industry under the new historical conditions and effectively promote the transition of the packaging industry to a resource-saving and environment-friendly low-carbon development model is an important choice for China's packaging industry. On the one hand, to maintain the packaging industry to serve the national economy in a healthy manner, and on the other hand, to combine the development of the packaging industry with the carrying capacity of the natural environment, and to achieve the ultimate goal of coordinating economic and social development and coordinating the harmonious development of man and nature. The development of science and technology, the affluence of life, and the sound development of ecological science have become the most pressing and thorny issues before the interface of the Chinese packaging industry.
For the sake of sustainable economic and social development, and in order to solve the contradiction between resources and the environment, the tide of green packaging or the green revolution has been rising in various countries. The concept of green packaging has two meanings: one is to protect the environment and the other is to conserve resources. The two are complementary and inseparable. Among them, the protection of the environment is the core. Saving resources and protecting the environment are closely related, because saving resources can reduce waste, and in fact it is protecting the environment from the source. Specifically, green packaging should have the following meanings:
Reduce packaging. The green packaging should be the least amount of appropriate packaging under the conditions of protection, convenience, and sales. Europe and the United States and other countries listed packaging reduction as the first choice for the development of non-hazardous packaging.
The packaging should be easy to reuse (Reuse) or easy to recycle (Recycle). Repeated use, or through the recovery of waste, production of recycled products, incineration and heat energy, composting to improve soil and other measures to achieve the purpose of reuse. It neither pollutes the environment nor makes full use of resources.
Packaging waste can be degraded (Degradable). In order not to form permanent waste, non-recyclable packaging waste must be decomposed to achieve soil improvement. All industrial countries in the world attach importance to the development of biological or photodegradable packaging materials. Reduce, Reuse, Recycle, and Degradable are the 3R and 1D principles recognized by the world in the 21st century for the development of green packaging.
In recent years, due to the impact of global climate change, the development of a low-carbon economy has become the consensus of the world. Research and development of green packaging materials with low-carbon characteristics has begun to enter the vision of the packaging industry. This new requirement has given green packaging updates and more. More than that, it means that in the entire life cycle of packaging products from raw material selection, product manufacturing to use and disposal, green packaging not only meets the requirements of ecological and environmental protection, but also needs to consider its source to the entire life cycle process. The amount of greenhouse gas emissions or carbon dioxide emissions generated in China. Green packaging is not necessarily low-carbon, whereas low-carbon packaging is not necessarily green. From a technical point of view, green low-carbon packaging means that not only the 3R and 1D principles of green packaging are met from the source to the entire life cycle, but also the greenhouse gas emissions generated during the entire life cycle must be low, in addition to requiring packaging materials. In addition to being resource-recyclable and reusable, it also requires resource conservation and climate-friendliness. This undoubtedly raises higher technical and environmental requirements for the development and upgrading of the packaging industry.
Analysis of the Carbon Footprint of Plastic Packaging
The high level of industrial production has created a material civilization for humans and has also brought a series of environmental problems. Many global environmental problems such as environmental pollution, depletion of resources, and ecological destruction have constrained the sustainable development of the economy and endangered the long-term interests of mankind. At present, packaging products are involved in environmental destruction in the following aspects: the use of chlorofluorocarbons in the production of foamed plastics leads to a reduction in the earthâ€™s ozone layer; the â€œwhite pollutionâ€ caused by the disposal of disposable foamed plastic tableware is still very serious; packaging waste Rivers, lakes, and oceans cause water pollution; papermaking harmful substances also pollute water and soil. Therefore, the packaging industry must not only care about the quality, performance, and cost of the packaged products, but also the environmental impact of packaging products and the consumption of resources. Therefore, only the development of green packaging is the only choice for the sustainable development of the packaging industry.
From the comparison of greenhouse gas emissions and Global Warming Potential (GWP), the plastic packaging industry has the largest damage to the ozone layer in the entire packaging industry, especially the large amount of greenhouse gases emitted during the foaming process. Before analyzing the foaming process, it is necessary to briefly introduce the mechanism of chlorofluorocarbons and their destruction of the ozone layer.
Chlorofluorocarbons (chlorofluorocarbons, also known as CFCs) refer to a group of similarly-structured compounds that replace some or all of the hydrogen atoms in a hydrocarbon by a fluorine or chlorine atom, and are the culprits of the destruction of the ozone layer. Due to its high stability, it does not self-ignite, does not contribute to combustion and does not easily undergo chemical changes, and has little harm to human body. It is therefore used throughout a wide range of industrial and daily life products. Among them, CFC-11 (CCl3F), CFC-l2 (CCl2F2) and CFC-113 (C2Cl3F3) are the three most used raw materials, and the scope of use includes blowing agents, refrigerants, cleaning agents, and sprays. Mechanism of chlorofluorocarbons destroying the ozone layer
As early as 1974, Americans Molina and Rowland proposed CFCs such as CF2Cl2 and CFCl3. Since they have a long lifetime in the troposphere, they will rise to the stratosphere, where CFCs in the stratosphere pass through the light. The chlorine atoms generated after decomposition will destroy the ozone layer. Therefore, the elimination of ozone-depleting substances has become a matter of high concern in various countries in recent years. At the UN Ozone Summit in Copenhagen, the resolution accelerated the decommissioning of ozone-depleting substances. In January 1993, the Chinese government approved the implementation of the "China's National Program for the Phase-out of Ozone Depleting Substances" (hereinafter referred to as the "Programme"). The "Program" focused on issues such as the operation of the industry's overall elimination mechanism and alternative technological route choices. Investigated and verified the production and use of ODS and its development trend, and further defined the overall elimination strategy and industry elimination plan. The "Programme" pointed out that the reduction of China's ODS production should be synchronized with the implementation of alternative technologies and the production and construction of alternatives to meet domestic consumption requirements.
Obviously, ODS reductions must be synchronized with product substitution. Otherwise, it will hinder the rapid and healthy development of the national economy. Faced with the huge economy of the national economy, we cannot accomplish this historic mission in one step, but we can find areas and spaces for something to be achieved. Taking the packaging industry as an example, we can use life cycle analysis (LifeCycle Analysis, abbreviated as LCA) to classify them into short-life cycle packaging and long-life cycle packaging according to the life cycle of packaging. For those packaging with long life cycle, product life is usually longer than the packaging life cycle, so these packaging is usually disposed of after its use value is fully used, there is no space for recycling; and for short life cycle packaging, packaging The use cycle is much shorter than the product life cycle, so there is a huge space for recycling, so as to avoid the huge waste of resources caused by arbitrary disposal.
In 2006, Wal-Mart creatively invented a 7S principle that aims to evaluate and document Wal-Mart and Sam Club's suppliers to improve the environmental packaging process, the Sustainable Packaging Scorecard, and to define environmentally-friendly packaging. Among these principles, it is renewable. And these two important principles can be recycled will undoubtedly make green packaging become the mainstream trend of the future Wal-Mart's global supply chain, which also makes the production of greenhouse gas emissions in the EPS foam plastic in some short-life cycle product packaging At the end of the day, it is even more urgent to develop low-carbon and environmentally friendly alternative packaging. In this case, the development direction of China's packaging industry can only take the green packaging road with low carbon characteristics.
The best path for green, low-carbon packaging - cellular packaging materials
The high-strength honeycomb paperboard material is a new type of green and environmental protection packaging material that has been developed in China in recent years to save resources, protect the ecological environment, and has a low cost. It has the advantages of lightness, strength, rigidity, and stability, and represents a new type of packaging. Patterns and ideas. In terms of volume, small motors, such as electronic products, can be used in large-scale electromechanical products such as aircraft engines. In terms of weight, cellular phones with a weight of several hundred grams, and cellular components as large as several tons, can use honeycombs. Cardboard packaging. The application of honeycomb paperboard has already demonstrated the unparalleled superiority of other packaging materials. Moreover, as an environmentally friendly material, it has the characteristics of being naturally degradable, not polluting the environment and recycling. Moreover, using one ton of recycled paper honeycomb material can replace approximately 40 cubic meters of packaged wood or approximately 50 cubic meters of EPS white foam, which can greatly reduce the use of wood or white foam, protect the ever-decreasing forest resources and continue Vulnerable ecological environment.
The structure and main features of honeycomb packaging materials
The HeLiSheng Honeycomb material based on paper-based fibers is a lightweight, high-strength structural composite material that was modeled after Beehive's honeycomb structure. It uses recycled recycled paper as raw material ( Among the known fiber materials, it is the cheapest.) In addition to its advantages of high strength, light weight, and material saving, it also has the characteristics of low cost and 100% regeneration and recycling. It is an ideal resource-saving and environment-friendly new material.
From the point of view of the use of materials, paper honeycomb composite material is a structural material with low material consumption, high material utilization, low energy consumption, and low price and environmental protection characteristics. Its promotion and application will change human use and manufacturing entities. The methods and methods of materials will have a tremendous impact and impact on the design, manufacture and production of future products. Based on the above characteristics, HeLiSheng Honeycomb Materials was selected as one of the 16 most insane new materials in the future by the US â€œMassive Machineryâ€ magazine in 2009 and predicted that it will gain more in the future product design and manufacturing. Development and application. This article only analyzes the application of HeLiSheng honeycomb materials in the packaging field.
The structure of a typical paper honeycomb packaging material is shown in the following figure. It is a standard honeycomb sandwich structure, which is formed by bonding two upper and lower face paper sandwich honeycomb cores. The honeycomb sandwich structure has outstanding compressive and bending resistance capabilities, and its most notable feature is to obtain maximum force with minimum material, ie, the maximum strength/weight ratio, which is the root cause of honeycomb composite materials being favored.
Its main features include:
Light weight, less material, and lower cost. The honeycomb sandwich structure has the greatest strength/weight ratio compared to the other various plate structures, and thus the finished product has a good performance/price ratio, which is the key to the success of the honeycomb paperboard. For example, the density of ordinary honeycomb paperboard is about 30kg/m3~50kg/m3, which is about one-third of the density of ordinary five-layer corrugated cardboard. The material cost of ordinary honeycomb paperboard is about the same as that of heavy seven-layer corrugated cardboard. Two thirds. Compared with EPS foam, under the same compressive strength, honeycomb paperboard is 20%~30% lighter than EPS, and the material is saved. In theory, its material cost is lower than that of EPS material. However, in actual application, the material price depends mainly on In the production of honeycomb materials and application areas.
High strength, smooth surface, not easily deformed. The honeycomb sandwich structure is approximately isotropic, has good structural stability, and is not easily deformed. Its outstanding compressive strength and bending resistance are the most important characteristics required for box-type packaging materials. Ordinary honeycomb paperboard can bear 2~5 kilograms of pressure per square centimeter, which is 5~10 times that of common corrugated board. The bending strength of ordinary honeycomb paperboard is 2 to 5 times that of reinforced corrugated board, which is 5 to 30 times that of ordinary corrugated board. Compared to EPS foams, honeycomb paperboards have 30% to 50% higher compressive strength than EPS foams at the same density.
Shock resistance, good cushioning. Honeycomb paperboard is made of flexible paper core and face paper. It has good toughness and resilience. By changing the paper weight or aperture size of honeycomb paper core and changing the grammage of the paper, it can easily change the resistance of the paperboard. Compression strength and cushioning properties. At present, high-thickness honeycomb paperboard can replace the EPS plastic foam cushions that are now widely used or can be used as buffer boards between transport packages through simple processing.
Sound absorption and heat insulation. The interior of the honeycomb sandwich structure is a closed chamber filled with air, so it has good sound insulation, heat insulation and thermal insulation properties.
No pollution, in line with modern environmental trends. Honeycomb paperboard is made entirely of recyclable paper and can be recycled and used 100% after use. Even if it is not used, it can be degraded and absorbed by nature. It is a very good green packaging material.
Excellent mechanical properties
In the usual impression, cardboard is weak and difficult to weigh; but in reality, the structural form of the cardboard has an important influence on its physical properties. A number of studies and practical results have shown that the honeycomb paperboard material has good physical properties such as great bearing capacity, good elasticity, shock pressure resistance, bending resistance, light weight, and the like.
Forest Paper Product Carbon Footprint Analysis
The raw materials of HeLiSheng Honeycomb Material are paper-based fiber-based recycled corrugated paper. Its raw materials are derived from forest products. Therefore, it is very important to analyze and understand the carbon footprint of HeLiSheng Honeycomb Materials. If the paper honeycomb material itself is a carbon-emitting material, although it is green, replacing it with existing plastic packaging materials is not a good choice; if the honeycomb material has low carbon emissions, It is a kind of green packaging material, and it is also low-carbon. It deserves to be advertised and promoted with great fanfare, and it has been more widely promoted and applied.
Regarding the analysis of the carbon footprint of forest products, the European Paper Industry Association issued a development paper for the carbon footprint of the paper and paperboard industry in September 2007, which gives an analysis of CO2 emissions during deforestation, papermaking and finished products. The calculation method, and summarized the ten steps of the papermaking and paper products industry to analyze and calculate the carbon footprint:
Forest carbon storage
Trees absorb large amounts of carbon dioxide in the atmosphere through photosynthesis, slowing the greenhouse effect. This is what is commonly called the role of carbon sinks in forests. According to relevant data, for every cubic meter of forest grown, the forest needs to absorb 850 kilograms of carbon dioxide and release 620 kilograms of oxygen. The forest is an absorber, storehouse, and buffer for carbon dioxide. Conversely, once the forest is destroyed, it becomes a source of carbon dioxide emissions.
Therefore, a sustainable forest management plan is a key issue for the raw material source of the forestry industry. Because of the renewable nature of forests, forest carbon neutrality can be achieved through effective forest management plans. That is, forest carbon sequestration required for forestry industry raw materials is equal to forest carbon sequestration supplemented by sustainable forest management plans. The forestry industry relies on sustainable forest management plans to ensure the balance of forest carbon sequestration, and to ensure the carbon neutrality of forest resources under the conditions that ensure the effective supply of forestry paper raw materials.
Carbon storage of forest products
The deforestation of trees from sustainably managed forests is essentially a form of forest carbon sequestration. If they are delayed or permanently retained, these carbon sequestrations do not increase the carbon dioxide content of the atmosphere but are stored as products. They can be seen as a way of carbon storage, where forest carbon sequestration is stored in forest paper products. In the United States, for example, the carbon storage capacity of forest paper products is as high as 100 million tons per year, and the carbon storage of forest products is increasing every year. The increase in carbon storage in forest products is equivalent to the reduction of carbon dioxide in the atmosphere.
Until a better carbon storage method and technology has been found, relying on afforestation and sustainable forest management programs can increase forest carbon sinks, and treat the carbon storage effect of forest products as an efficient and simple carbon The storage methods and techniques, on the basis of ensuring the availability of raw materials for the forestry industry, ensure that the stored forest carbon and its products are not released into the atmosphere again, thereby reducing the carbon dioxide content in the atmosphere.
Carbon emissions from forest products manufacturing facilities
During the manufacture and production of forest products, the carbon dioxide emissions from all manufacturing facilities are included in the analysis and calculation of this step. They include the upstream pulp mills, paper mills, cardboard mills, and subsequent carton processing plants. It includes facilities for converting wood fibers or recycled fibers into finished products, as well as carbon emissions from pollution control and various treatment devices.
Carbon emissions associated with the production of wood fibres
This step involves the analysis and calculation of carbon emissions from the production or recovery of fiber from wood fiber. For wood fiber, it includes carbon emissions from forest management and tree felling. For recycled fiber, it includes carbon emissions from the collection, sorting, and treatment of recycled paper before recycling. These carbon emissions are generally outside the paper mill. Emissions do not include carbon emissions from transportation.
Carbon emissions from production of other raw materials and fuels
Carbon emissions are produced during the manufacture of fuels and raw materials (such as chemicals and additives, etc.) that do not involve forest products. It includes the need to purchase electricity to produce these raw materials. Usually these emissions are not controlled by forest products manufacturers, but they need to be considered in the calculation of the entire carbon emissions.
Purchase of electricity and other energy-related carbon emissions
The carbon emissions from the purchase of electricity, steam, and heating energy, which are directly related to forest products, also include carbon emissions from pollution control and use of electrical devices such as exhaust gas and solid waste emission control.
Carbon emissions related to product transportation
All carbon emissions generated during the transport of raw materials and products in the product value chain, including carbon emissions from logs, recycled fibers, other raw materials, intermediate products, finished products, and used products.
Carbon emissions during use of forest products
Unlike electrical products, forest products do not produce carbon emissions during use.
Carbon emissions at the end of forest products
If paper products are fully recycled after they have completed their life cycle, they will not produce carbon emissions, but some forest products will be landfilled or incinerated. During landfilling, some of the waste will generate methane gas, which is a greenhouse gas with a relatively high carbon dioxide equivalent. Discarded paper products also produce carbon emissions during incineration.
As the disposal of waste is a very uncertain factor, different countries, regions and cities have different treatment methods. Therefore, the calculation of carbon emissions is relatively difficult and generally exceeds the control of the manufacturer. However, for the paper industry and packaging paper, waste paper is easy to recycle and has a certain value. There has always been a relatively complete recycling network and system. If properly recycled and managed, it can greatly reduce carbon emissions.
Avoid emissions and reversals
This step is an option. When people extend the analysis boundary of the carbon footprint, it can be found that there are many places in the product that can not emit or reduce emissions. When using an analysis that avoids emissions as a carbon footprint, it is critical that the assumed assumptions and methods of analysis are transparent and interpretable to the relevant stakeholders.
Based on the above CEPI analysis and calculation methods, European corrugated paper and paper products industry association (Pro-Carton) has developed a method for analyzing and calculating the carbon footprint of corrugated paper and paper products. This analysis method assumes that the raw materials of the forestry paper product industry are derived from sustainable Managed forests can reach carbon neutrality. In addition, considering the uncertainties of product recovery during the life cycle of forest products, the analysis of carbon footprint includes only the analysis from the cradle (forest) to the user's threshold (from cradle to gate). The final analysis result is The carbon dioxide equivalent of one ton of corrugated paper and paper products is 1004kg, but the carbon dioxide equivalent of one ton of corrugated paper and paper products is 1474kg. After mutual cancellation, the amount of carbon dioxide stored per ton of corrugated paper and paper products is 470kg, this result has been recognized by the European Institute of Energy and Environment (IFEU).
The above analysis shows that forest products rely on the carbon sequestration function of forests to convert atmospheric carbon dioxide into a kind of carbon sequestration. If this product is not burned and landfilled, they will no longer produce carbon dioxide emissions. . Therefore, paper packaging is not only a green packaging material, but also low-carbon, and can be seen as a means and means of carbon storage.
Low-carbon characteristics of HeLiSheng honeycomb materials
HeLiSheng Honeycomb Material is a full-paper product made from recycled paper as a raw material. Its main composition is the same as that of traditional corrugated paper and paperboard. Therefore, the carbon footprint of HeLiSheng Honeycomb Paper and Paperboard is analyzed. The above analysis results and calculation methods of corrugated paper and cardboard can be directly quoted. The carbon dioxide equivalent of each ton of Hefei Sheng honeycomb paper and paperboard produced is about 1004kg, but the carbon dioxide equivalent stored in one ton of honeycomb paper and paperboard is 1474kg. After mutual cancellation, one ton of honeycomb paper and paper products are stored. The amount of carbon dioxide is 470kg, which is equivalent to a reduction of 470kg of carbon dioxide emissions.
For the specific analysis of HeLiSheng Honeycomb Material itself, because its raw material adopts recycled paper made from full recycled waste paper, it constitutes a complete regeneration cycle and resource recycling process from the raw material to the end of the product, even in the honeycomb material. The waste paper produced in the production process is also sent back to the paper mill for recycling and recycled paper. As a result, Holocell cellular materials generate very low CO2 emissions throughout their life cycle.
According to the analysis of the methane quantification model during the landfill process of organic waste, the amount of methane produced per kilogram of paper waste is 0.270 kg, and the amount of carbon dioxide gas is 0.673 kg. Since the greenhouse gas GWP value of methane is quite high, which is 21 times that of carbon dioxide, it can be calculated that the equivalent carbon dioxide emission equivalent to emission reduction is approximately 8.88 tons per ton of biomass produced per ton of honeycomb material. It can be seen that the recycling of waste paper has great value for the reduction of greenhouse gases.
Based on the above analysis, the use of HeLiSheng Honeycomb Paper as a packaging material has very unique advantages. The raw material is the use of completely recycled waste paper resources. Even though its source comes from the forest, it is planned to produce and cut through continuous forest management. , is to maintain the carbon dioxide absorption function of the forest and to achieve carbon neutrality, and that Helisheng honeycomb material itself is a kind of forest paper product, has the function of carbon storage, and can be considered as a way to store carbon dioxide. By means of complete recycling and recycling of waste products from He Lisheng, the carbon dioxide will continue to be locked up and cannot be released into the atmosphere as greenhouse gases.
Application of He Lisheng Honeycomb Packaging Materials
As a new type of packaging material, HeLiSheng honeycomb materials and technology not only save resources, protect the environment, but also achieve the purpose of carbon emission reduction. It is a green low-carbon material and technology worthy of promotion and application, and has a broad Market and application prospects. Specifically, in the application of carbon emission reduction, HeLiSheng honeycomb materials can achieve emission reduction in the following four ways: storing carbon dioxide in the form of carbon fixation; reducing carbon in a resource-saving manner; and reducing greenhouse gas emissions in the form of full recycling. Replacing high-carbon materials with low-carbon materials to achieve emission reductions.
The output value of China's packaging industry in 2008 has reached 860 billion, and it is expected to reach 1.2 trillion in 2010, involving paper, metal, plastic, machinery, chemical and other fields. As China has become a processing factory and product manufacturing center in the world, a variety of packaging materials will be developed, especially environmental protection, energy saving, resource-saving green packaging materials, but also by countries and countries around the world. In particular, the developed countries welcome and encourage, and after Chinaâ€™s accession to the WTO, as more and more products are manufactured in China, the normal tariff barriers are reduced, and Western developed countries are more in the form of technical environmental protection barriers against Chinaâ€™s The product proposes higher technical and environmental requirements. Since 1998, the U.S. and EU restrictions on wood packaging materials in China and the EUâ€™s adoption of the new environmental protection law in 2002 have increased the recycling rate of packaging waste to 65%, reflecting the urgent need of the world market for new types of energy-saving and environmentally friendly materials. Needs and expectations. In recent years, the development of a low-carbon economy and the possibility of raising the cost of products through the imposition of carbon taxes will pose new challenges to the products and packaging materials made in China. This undoubtedly creates a good opportunity and a huge opportunity for the development of honeycomb packaging materials. Expansion capacity.
The promotion and application of new types of green packaging materials is a matter of urgency and a major event. Among the numerous packaging materials and packaging methods, "paper-based plastic molding" is increasingly becoming an inevitable trend of international popularity. Honeycomb-structured paperboard is the world's rising resource conservation, environmentally friendly, simple production, good buffering performance, and low cost in recent years. Green packaging material. The honeycomb paperboard material is a paperboard composite made from paper honeycomb cores on the upper and lower sides with face paper. It can be made into packaging products of various sizes and shapes according to product protection requirements, with good cushioning performance and packaging and other packaging. The advantage is to replace the ideal foam cushioning material for EPS foam.
As a cushioning material, honeycomb paperboard can replace EPS foamed plastic, and can be recycled and recycled, reducing the increasingly serious "white pollution" problem. Even if it is abandoned, it can also degenerate on its own without polluting the environment. Honeycomb packaging materials save resources, protect the ecological environment, and meet the development trend of international packaging industry materials. Although there are many problems in the development of the honeycomb material industry in China, we can still see the promise of honeycomb packaging products. It will become the mainstream of product packaging materials in China's electronic information, home appliances and other industries. Therefore, promoting green packaging improvement programs in the packaging industry is a concrete manifestation of low-carbon economy and low-carbon technologies.
For example, in 2008, Haier Group launched its environmentally friendly packaging innovation planâ€”OlympicProject 2008. It plans to use 1 to 2 years to switch all Haier Group's product packaging to environmentally friendly packaging, and achieve Haier Group's product packaging innovation and environmental protection upgrade.
It is understood that only a Haier company, the annual demand for environmentally friendly packaging is more than 1 billion yuan. China's home appliance information industry is not only huge in the domestic market, but because of its high quality and low price, its annual exports have increased substantially. According to statistics, in 2008, China produced a total of 147 million computers, 44 million lines of program-controlled switches, 90 million color TV sets, 83 million air conditioners, 48 â€‹â€‹million refrigerators, and 39 million washing machines. The packing boxes needed for such a huge market , cushioning materials and shipping pallets are all amazing numbers.
According to statistical data, the annual output of EPS foam in China's packaging industry is about 1.5 million tons, which is equivalent to about 100 million cubic meters of cushioning packaging materials, and shows an upward trend year after year. If our government can vigorously promote the upgrading of the packaging industry, use green packaging or promote the "paper-based plastic" project, reduce 30% of EPS packaging materials, it is equivalent to reduce the emission of white pollutants of 450,000 tons of EPS, the volume of Equivalent to 30 million cubic meters, its reduction in carbon dioxide emissions equivalent to approximately 5 million tons.
Developing green packaging and reducing white pollution is already a global consensus, and integrating the concept of low-carbon emissions into R&D and promotion of green packaging is even more of a general trend. It is also the people's intent, which is also the development of China's packaging industry and the upgrading of the packaging industry. The only way to go.
In the specific practice, research, development and application of green packaging materials with low carbon characteristics is the key to achieving green and low carbon development. Replacing traditional plastic packaging materials with full paper packaging materials is the best way to develop China's green, low-carbon packaging. It can not only achieve the purpose of resource conservation and white pollution reduction, but also significantly reduce carbon dioxide emissions for packaging in China. The industry's development of a green, low-carbon road provides a practical solution and technical solution.
