Since the National Development and Reform Commission released the list of the first batch of national circular economy pilot units in October 2005, the scientific and technological innovation of circular economy enterprises and units, the economic operating efficiency, and the future development direction have been receiving public attention. They are both pilot fields for China's sustainable development of the environment and the development of new economic growth points, and are also forerunners and explorers of an unknown road.
Recently, the reporters, together with the National Development and Reform Commission and the Chinese Academy of Engineering, conducted a "recycling economy expert trip" activity and visited Beijing Yingchuang Renewable Resources Co., Ltd. in the pilot units, Shilibao Town in Miyun County, Beijing, and the Beijing Cement Group, Beijing Jinrong Group. The status of its development was investigated.
Resource utilization promotes bi-directional circulation
The use of recycled waste resources is the key to circular economy. There are two levels of circulation, namely the enterprise's external circulation and internal circulation. External circulation is the maximum utilization of resources between companies through cooperation with other companies. The internal cycle is to maximize the use of internal resources within the company, minimizing waste and pollutant emissions at all stages of production. The homogeneity conversion of waste plastic bottles by Yingchuang is an external circulation type.
Yao Yaxiong, general manager of Yingchuang Company, said that in Yingchuang, the recycled plastic bottles will be made into recycled PET bottle-level slices after being subjected to a series of production processes as materials for producing food packaging. Relevant tests showed that the quality of the reconstituted food grade slice was exactly the same as the quality, nature, function and hygiene of the original bottle grade slice, and it complied with the national PET slice food hygiene standard GB13114, and reached the GB17931-2003 bottled PET standard. The acetaldehyde content standard completely replaces the original bottle-level section. Since raw PET bottle chips are made from petroleum, the consumption of 6 tons of oil per ton of PET is calculated. As a result, the equivalent of 600,000 tons of oil will be consumed in one year in Beijing. If Yingchuang's external circulation mechanism can be promoted nationwide, it will be able to save a lot of oil resources.
The Beijing Cement Plant combines the external circulation and internal circulation of the company. In the aspect of external recycling, the Beijing Cement Plant will cooperate with various units such as sewage treatment plants and manufacturing factories that are prone to produce industrial waste, including various tailings and industrial wastes containing silica, alumina, iron oxide and calcium oxide. Urban sludge generated from urban sewage treatment plants and domestic garbage are included in raw materials and fuels for cement production to solve the hidden dangers of simple landfilling and secondary pollution.
According to the existing production capacity of the Beijing Cement Plant, the industrial waste that can be disposed of and comprehensively used in one year reaches 100,000 tons, and the amount of urban sludge that can be treated reaches 150,000 tons. In terms of internal recycling, the plant is mainly engaged in cleaner production and is committed to recovering dust generated in the cement production process and the material deposits in the production and handling sectors. Cement production dust emissions were once the main environmental pollutants of cement plants. After recycling, dust can directly enter the finished products. The dust recovered from kiln heads and kiln tails can also participate in production once again, which not only reduces resource consumption but also reduces air pollution. In addition, the materials left in the cement production process during handling of large quantities of materials can also be recycled and reused by means of subsection cleaning.
Different from the industrial cycle, the agricultural circular economy draws materials locally, circulates in the field, and gains on the spot. According to experts from the National Development and Reform Commission, the circular economy of agriculture has existed in China since ancient times, and the Sangji fish pond that was implemented by the ancients was a typical example. History contains: "The local food in Shunde is well-being ... ... are all dependent on people's species of mulberry, sericulture, pig raising and fish farming ... ... fish, pigs, silkworms, mulberry four joint raising," was developed during the Ming and Qing Dynasties A kind of ecological agriculture prototype.
Shilibao Town, Miyun County, Beijing Municipality, through the development of ecological agriculture featuring the production of green and safe agricultural products, actively explores new modes of circular economy practice for clean production in rural areas, conservation of agricultural resources, and comprehensive utilization of renewable energy sources. Currently, the effective irrigation coefficient of farmland irrigation water in the town 0.95, the livestock sewage treatment rate reached more than 80%.
Many gutters are encountered during exploration
In the process of circular economy development, enterprises need to spend huge amounts of money in environmental protection, scientific and technological innovation, and they may also make detours in technological innovation. This often becomes the first batch of "crab-eating people" must face the risks.
According to Guo Xin, an executive director of Yingchuang, one of the company's current major investments is the recycling cost of discarded plastic bottles. In Europe, the recycling price of discarded plastic bottles is about 200 euros a ton, and in China it is about 600 euros a ton. The surplus that was "reduced" by the cost of recovery did not have a more favorable price than the original raw material manufacturers. In China, where raw material production capacity of plastic bottles was originally excessive, it was difficult to take the initiative in fierce market competition.
Zou Zuyu, the vice president of the China Packaging Federation, said that lacking a mature recycling system is the fundamental reason for the unfavorable recycling. The unfair cost calculations of Yingchuang (a large amount of cash transactions but no tax payment) have overwhelmed Yingchuang. In terms of recycling raw materials, Yingchuang also faces fierce competition with a low level of “peerâ€.
According to an industry source, many food grade PETs in Beijing were broken into suburban areas and transported to small factories for drawing woven bags. He said that it is this kind of unreasonable competition that makes enterprises that embody the trend of the future circular economy tend to compete with these small companies that pollute the environment and abuse resources. Yingchuang currently has to set foot in the construction of a recycling system. It plans to build six specialized waste plastic bottle sorting and packing centers in Beijing. In 2008, two sorting and packing centers, Yaojiayuan and Hanjiachuan, have been established. "If we now build a company like Yingchuang, we only need half of our initial investment," Yao Yaxiong said.
The Beijing Cement Plant faces high costs in the pretreatment of industrial hazardous waste. Fu Qiutao, general manager of Beijing Cement Plant, said that the plant has been exploring the circular economy production mode for the 10th year. During this period, it solved and solved a series of technical problems in the cement factory's use of the existing cement kiln system to dispose of industrial waste: including The safe transportation and classified storage of hazardous wastes; the conflicts between the disposal of wastes caused by the complex composition of solid wastes and the stability of the kiln conditions; the chemical reactions such as fever, explosion, and the generation of toxic gases that may occur between different wastes; halogen substances Determination of the ratio of incineration of the alkaline substance, etc.
He believes that the treatment of waste is simple and the cost of classification during pre-processing is too high, which is mainly caused by poor garbage classification habits. If the front-end classification is done well, then the cost can be greatly reduced. In addition, although the Beijing Cement Plant has an annual capacity of 100,000 tons of industrial hazardous waste, it received only 50,000 tons last year. It is reported that Beijing's industrial hazardous waste treatment rate is already the highest in the country, reaching 94%, but this phenomenon still exists, other areas can be imagined.
Coincidentally, the circular economy pilot of Shilibao Town in Miyun County in Beijing has also encountered difficulties. Lin Cong, from Beijing Agricultural University, discovered that a group of original equipment worth more than RMB 300,000 to be used for the transformation of cow manure wastes and biogas production at Shilibao Town Dairy Farm has not been applied. "This equipment is mainly used for sewage treatment and is used to generate biogas with low efficiency. It is recommended to make technical improvements or add an industrial separator for pre-treatment of waste."
“Because the managers are farmers themselves, pilots of the rural recycling economy have inherent weaknesses in the coordination of technology, equipment, and hardware and software.†According to relevant personnel of the Miyun County Development and Reform Commission, “At present, we do not need to engage in agricultural circular economy management personnel. ."
Central economy must first realize the economic cycle
Cheng Huiqiang, executive vice president of the Institute of Recycling Economics at the Beijing Polytechnic University, said in an interview with this reporter that the development of the circular economy involves many factors. However, the company’s ability to survive and profit in the fierce competition is the most important aspect. This requires the pilot units to explore profitable channels in multiple ways, and first implement their own economic cycles to help promote circular economy.
As the first batch of “crab-eating peopleâ€, pilot units discovered a huge circular economy market. It is understood that China has 3 million tons (about 1.2 trillion) plastic bottles that need to be recycled every year, which undoubtedly gives the company a great opportunity for development. The annual burning of sludge slag by the Beijing Cement Plant produces 380,000 tons of incineration material. As an active cement compound material, the annual output value of RMB 68,400,000 is calculated at a market price of 180 yuan per ton, which also has significant economic benefits. “We currently account for half of our profits from cement production and half from industrial waste disposal.†Fu Qiutao, general manager of Beijing Cement Plant, said that Beijing Cement Plant had a net profit of about RMB 140 million in 2008, of which nearly 70 million came from environmental protection. Industry and circular economy.
In addition to this, at this stage, companies can participate in the innovation of environmental protection technology and they may also gain industry opportunities. Taking Yingchuang as an example, the same factory in China that can achieve food-grade standards is currently the only one. If we can standardize the process, process, control, standard, and management of Yingchuang as an example of future expansion, then Yingchuang not only itself It is a renewable plastics manufacturing company and can also become a technology and equipment provider for other similar companies. The reporter learned from the interview that both Yingchuang and Beijing Cement Plant had this plan.
When it comes to the agricultural recycling economy, it does not need to say much about the significance of solving the "three rural issues" and increasing the income of farmers. According to Cheng Huiqiang, the differences between the agricultural cycle and the industrial cycle can be summarized in 16 words: infrastructure, circulation nodes, node support, and human settlements. At present, China’s agricultural recycling economy needs to improve its technical grades, enrich its recycling nodes, and ultimately increase farmers’ income and improve farmers’ lifestyles.
