“Love the ecological environment like loving your eyes and treat the ecological environment like life.â€
The "white pollution" of the earth is obvious to all. Governing "white pollution" has become the trend of the times, and it has reached the point where it cannot be ruled. The theme of this year's World Environment Day is "the quick battle of plastic warfare."
Sun Dong, secretary of the Nanle County Party Committee of Henan Province, said on the World Environment Day on June 5th that the World Forum on the Development of White Pollution will be a common home for mankind. The construction of ecological civilization is related to the sustainable development of the Chinese nation. The fundamental plan. About 5.5 billion tons of petroleum-based plastic products are landfilled or randomly disposed in the natural environment. The “white pollution†produced by them has caused serious damage to the soil and the marine environment, and has become an important issue of common concern worldwide. In the face of the problem of “white pollution†swallowing up good fields, blocking villages and towns, and damaging living things, it is timely to promote the use of bio-based materials to produce degradable plastic products.
Be good at the moment, be born
In recent years, Nanle County has actively responded to the call for the development of bio-based materials in the country. Based on the support of the national and provincial development and reform departments for the development and application of bio-based materials, Nanle County has taken the lead in creating the first professional industrial park nationwide. — Bio-based Materials Industrial Park, Nanle County Industrial Cluster, Puyang City.
Liu Bing, the county magistrate, said that at present, the industrial base of Fuyang bio-based materials in Nanle County has reached 222,000 tons in 2017, and the capacity at the end of this year is expected to reach 500,000 tons. It is estimated that within five years, the bio-based materials industry park will attract more than 30 bio-based materials companies to settle in and cultivate five leading enterprises. The total output value of the two listed companies and materials industry parks exceeds 10 billion yuan.
Since the international financial crisis, biotechnology and industry in the world have shown accelerated development. Major developed countries and emerging economies have deployed the development of bio-industry as an important field for gaining future technological competitive advantages. The bio-industry is a strategic emerging industry identified by China.
The Notice of the State Council on the Development Plan of the Indian Producing Industry was issued on December 28, 2012, which identified the bio-industry as a strategic emerging industry of the country. In 2014, the National Development and Reform Commission and the Ministry of Finance jointly organized and implemented the special project on bio-based materials, and issued the Notice of the General Office of the Ministry of Finance of the General Office of the National Development and Reform Commission on the Organization and Implementation of the 2014 Special Project on Bio-based Materials, requiring regional cluster construction and Application of products as a development carrier, through the demand side to pull the supply side to promote the combination, promote the development of non-grain bio-based materials industry chain, build a number of high-density, high-level, industry-university-research organic combination, leading the demonstration of significant industrial clusters, accelerate Demonstration of the application of regenerative and degradable bio-based materials to promote significant progress in the replacement of petrochemicals by bio-based products.
Nanle County Bio-based Industrial Park is born in such a big background.
Technology leadership, turning waste into treasure
According to Li Jifeng, director of the organization department of Nanle County Committee, the county's bio-based materials industry park is the first professional industrial park in China. This is the only one in Henan Province, and there are only two in the country.
The park has already settled 18 projects with a total investment of 4.2 billion yuan, and has completed 940 million yuan. 12 projects have been completed and put into production. In 2017, the production capacity has reached 222,000 tons and the output value has reached 690 million yuan. Through industry investment and project expansion, the capacity will reach 500,000 tons by the end of 2018. It is estimated that within five years, the park will attract more than 30 bio-based materials companies to settle in, and cultivate five leading enterprises and two listed companies. The total output value of the park exceeds 10 billion yuan.
On June 5, Zhang Li, deputy director of Nanle County Foreign Investment Administration, in Henan Longdu Tianren Biomaterials Co., Ltd., located in Nanle County Bio-based Industrial Park, said that the successful synthesis of polylactic acid copolymerization technology by Nanle related enterprises The industry leader has applied for international patents. Up to now, the technology for producing polylactic acid in the United States is still to produce an intermediate called lactide before it can synthesize polylactic acid. This is called two-step synthesis of polylactic acid in the industry. Nanle can directly produce polylactic acid copolymer in one step, saving a lot of production, management and time costs.
Nanle County has not only successfully developed the technology of producing polylactic acid copolymer using corn as raw material, but also successfully developed the technology of synthesizing L-lactic acid from bio-stalk as raw material. This technology has been successfully tested through 1000 tons of pilot line, Nanle County. A workshop with an annual output of 30,000 tons is being built, and it will soon be ready for trial production.
The advent of this technology can greatly reduce the contradiction between the huge increase in demand for corn and other foods. It is of great significance for the sustainable development of bio-based materials, the transformation of straw into waste, and the reduction of pollution caused by burning straw.
Completely degraded, multi-purpose
According to Lian Yunqiang, director of the Nanle County Development and Reform Commission, Nanle's biodegradable agricultural film, nursery tray, garbage bag, shopping bag, lunch box and other bio-based plastic products are bio-based materials to prevent white pollution. The ideal substitute can be 100% degraded to carbon dioxide and water within six months of composting conditions, and the products sell well both at home and abroad.
On the afternoon of June 4, the China Economic Herald reporter entered the Nanle County Bio-based Materials Industrial Park. In the production workshop of Henan Longdu Tianren Biomaterial Co., Ltd. in the park, the reporter first smelled a distinct popcorn scent. The reporter grabbed a granule of polylactic acid modified material and the smell of popcorn was more obvious. According to the person in charge of the company, bio-based materials are widely used and have broad prospects. Many products produced from bio-based materials can not only be completely degraded, but also the clothing, such as socks and clothes produced by the material, have natural fragrance and affinity for human skin, and are more beneficial to human health.
Due to the degradable nature of bio-based materials, and Nanle has mastered the time to artificially control degradation, the seedling tray made of bio-based materials can not only be factory-produced like the production of petroleum-based materials, but also Save the process of removing the seedlings from the nursery tray and then inserting them. In this way, not only saves production time, but also provides technical support for mechanized transplanting. In addition, the direct transplanting can more completely protect the roots of the seedlings, which greatly improves the survival rate of the seedlings and greatly shortens the time for returning the seedlings, and the average income per mu is about 7%.
In this regard, some people have made an analogy. "In terms of food production, the technology of producing seedling trays with bio-based materials is like Yuan Longping in China."
Doing deep and fine, the prospect is broad
Cui Yongjiang, deputy director of the Development and Reform Commission of Nanle County, said that in the world, only a few countries such as the United States, France, and Japan have a complete bio-based material industry chain, and an industrial cluster in Nanle County has formed a Complete industrial chain. In the bio-based material industry chain, the Netherlands and the United States mainly produce lactic acid and polylactic acid, while Japan and other countries have succeeded in producing downstream products. Nanle County has perfected the entire industrial chain from corn and corn stalks to sugar-L-lactic acid-polylactic acid-polylactic acid modified materials-terminal products.
Due to the high quality and low price of bio-based materials degradable garbage bags and shopping bags produced by Nanle County Bio-based Materials Industrial Park, most of the products are exported to Europe and America. Not only because the price of bio-based material garbage bags and plastic bags is higher than that of petroleum-based materials, merchants and consumers still do not accept this emerging green product, which is also related to the ban on plastics in Europe and the United States.
At present, European and American countries have basically implemented a comprehensive policy of prohibiting plastics. Recently, some media reported that a giant whale and a whale in Thailand died after five days of rescue. After dissection, people found a large number of black plastic bags from its belly, the number is more than 80, weighing about 16 kg. The whale also spit out five black plastic bags during the rescue. The staff concluded that the main cause of whale death was that the whales had eaten these black plastic bags.
The abnormal death of this whale has deeply stimulated people's nerves, giving people a more intuitive understanding of the pollution caused by petroleum-based plastic products to the earth.
According to Wu Jian, a professor at Zhengzhou University, as of 2015, humans produced nearly 8.3 billion tons of plastics, of which 6.3 billion tons became garbage. It is estimated that by 2050, humans will produce 26 billion tons of plastic waste. Some plastic waste was landfilled, and more plastic waste was discarded on land or in the ocean, so that the wonders of the “eighth continent†garbage island in the Pacific Ocean made the world shocked. The main components of these garbage islands are various plastic products produced from petroleum-based materials. As various plastic products produced from petroleum-based materials cannot be degraded, these increasingly large plastic wastes pose a serious threat to the pollution of the earth, causing people to Plastic garbage, a huge panic about white pollution. To this end, countries around the world have developed new materials to replace petroleum-based materials to avoid the spread of white pollution of plastic waste.
In this regard, some experts suggested that the relevant departments should investigate and investigate the practice of comprehensive ban on plastics in Nanle, and introduce a comprehensive ban on the legal level from the legal level, opening up more financing channels for Nanle Bio-based Materials Industrial Park, and More practical support is provided for R&D, production and application.
