Corn plastic: there are huge business opportunities

daily necessities and other industrial products made of corn plastic can be completely degraded into carbon dioxide and water after use, so people call corn plastic "magic plastic". There may be huge business opportunities. Wal Mart, a retail giant, said that since november1,2005, 3779 Wal Mart Supermarkets in the United States and Wal Mart Supermarkets in neighboring countries have begun to use corn plastic as food packaging. This kind of corn plastic is produced by nature works in the United States. At the same time, Wal Mart also announced that it would gradually promote corn plastic food packaging in Wal Mart Supermarkets around the world in the next few years, so as to completely replace the chemical plastic food packaging that has been used for a long time

as the largest retail supermarket in the world, Wal Mart has more than 5300 large and small supermarkets around the world, such as stores, shopping malls, member stores, community stores, etc. its consumption of food packaging can be imagined. Wal Mart said that although the price of corn plastic is higher than that of chemical plastic, it will increase the sales cost of Wal Mart. However, the chemical plastic food packaging is frequently exposed to cancer, which makes consumers lose trust in the chemical plastic food packaging. Only by choosing non-toxic, harmless and environmentally friendly corn plastic food packaging can consumers regain their trust in the fierce market competition

according to the data, corn plastic has been successfully applied in medical bone nails, tissue engineering medicine, etc., but its application in daily life has not made a breakthrough. Wal Mart's corn plastic action has made corn plastic, which has been wandering on the edge of the plastic industry, take the first step to enter the mainstream market, and the "jade fans" who are obsessed with corn plastic have completed a beautiful turn

in July, 2005, Professor Renjie, vice president of the school of materials science and engineering of Shanghai Tongji University and director of the Institute of nano and biopolymer materials, announced that the "one-step" production process of corn plastic that he had successfully studied had begun to be industrialized, and the price of corn plastic particles produced by the "one-step" process was $1000/ton, which was basically close to the price of genuine chemical plastic particles. This news also opened a "civilian" door to mass production of corn plastics

industry prospect

after ten years of polishing, the technology of corn plastics has matured, and the application of corn plastics by nature works has begun to enter the plastic industry. Although the carburized layer is obvious Most of them are still in the industrial test stage, but they have shown strong strength to show their strength in the plastic industry

the packaging industry bears the brunt. Plastic packaging products are a major pillar industry in the plastic industry, including plastic bags, food packaging boxes, beverage packaging, etc. Corn plastic is the most widely used in the packaging industry. In Japan, Europe and other countries, corn plastic has been applied to packaging materials

at the 2005 Aichi Expo in Japan, Japanese enterprises demonstrated the whole process of the production of disposable lunch boxes, drink cups, food packaging bags, plastic trays, etc. made of corn plastic, so that the quality of molded products can be degraded from a few grams to a few 10 kilograms. At present, packaging companies such as Asahi Kasei and toyoji cans in Japan have begun to set foot in the production of plastic corn packaging

at present, the raw materials of corn plastic all over the world come from nature works, and its high cost makes the packaging industry in the downstream industrial chain not form an industrial scale. The production of corn plastic products by packaging companies in Japan and European countries is only in the stage of promotion and industrial experiment in some regions

the materials used to make agricultural film mainly come from chemical plastics, and the non degradability of chemical plastics agricultural film has led to serious environmental pollution. The use of corn plastic agricultural film, after use, directly landfill and degrade the film in place, avoiding the pollution caused by chemical plastics. It is learned that agricultural film with corn plastic as raw material has been produced in some parts of Europe and China. However, some synthetic plastic mulch has added degradable materials, and the consequences are even more serious. Synthetic plastics are directly degraded into the land, resulting in the hardening of cultivated land

first, in the textile industry, the air permeability and hand feel of corn fiber made of corn plastic are better than those of polyester, which can change the shortcomings of polyester materials that are prone to static electricity and poor air permeability. Versace of France has applied corn fiber to some high-end menswear; DuPont company of the United States took a fancy to the permeability of corn fiber and used it in underwear; Some companies have developed socks and gloves made of corn fiber

in addition, corn plastic can also be used for plastic toys, plastic shells of household appliances, automobile interiors, plastic steel doors and windows, etc. For example, Fujitsu company in Japan has made portable computers with plastic corn shells, and some toy companies in Japan have begun to develop toys made of plastic corn

in addition to its wide application in daily necessities, corn plastic is particularly outstanding in medicine, and it is also the most successful application field of corn plastic. The first is medical bone nails. In the past, stainless steel bone nails were used to treat bone fracture and other orthopaedic diseases. Patients must undergo two operations before they can be cured. When corn plastic bone nails are used, only one operation is needed to implant the bone nails. When the disease recovers, the bone nails are also degraded in the human body. It is learned that the price of corn plastic bone nails is about 50% higher than that of stainless steel bone nails, but a large number of patients choose corn plastic bone nails in order to avoid the pain of two operations

corn (1) high performance carbon fiber and its composite plastics are irreplaceable in the application of tissue engineering scaffolds. The skin cultivation scaffolds in skin tissue engineering have always been a troubled problem. The corn plastic scaffold can be directly degraded into carbon dioxide and water after successful skin cultivation, which can greatly alleviate the pain of patients

alleviating oil consumption

tracing the origin of corn plastics should be after the global oil crisis in the 1970s. People are aware of the non renewable nature of oil. Perhaps one day in the future, human beings will lose oil resources, paralyzing modern human life that relies on oil as transportation power and daily needs. At this time, people began to look for alternative energy, hoping to find renewable and pollution-free energy to solve the impending oil crisis

in the following decades, physicians began to continuously study in the laboratory how to make plastics from renewable and pollution-free crops such as corn, sorghum and soybeans. Just ten years ago, the American nature works company, which was a subsidiary of Dow Chemical at that time, jointly developed the "two-step" production of corn plastic. After ten years of research and development, the strength and plasticity of corn plastics have basically reached the level of chemical plastics

the emergence of corn plastics has also given the petroleum industry, the lifeline of the plastics industry, a breathing space. The rise in oil prices has a direct impact on the price of chemical and plastic raw materials. According to the data provided by Tianjin Customs in 2004, the average import price of genuine plastic raw materials in primary shapes at Tianjin port in November 2004 reached 1166 US dollars/ton, an increase of 36.8% over the same period last year. By november2005, the price of plastic raw materials in Guangdong had increased by 66.7% compared with 2003, reaching about 10000 yuan/ton, while the price of imported plastic particles had increased by 85.7% to about 1400 dollars/ton

according to the analysis of insiders, the annual oil consumption of plastic manufacturing accounts for 4% of the annual oil production, and 136million tons of oil are consumed every year. Producing 1 ton of chemical plastics requires 3 tons of oil, while the global annual output of chemical plastics is 30million tons, which means that 100 million tons of oil will be consumed

imagine that it takes about 3 tons of corn to produce 1 ton of corn plastic. At present, the global annual corn inventory reaches about 100million tons. If all the corn plastics are produced, the annual output will be about 30million tons, which is equivalent to the global plastic demand in a year

some experts predict that with the continuous improvement of corn plastic technology and the continuous expansion of application fields, corn plastic will become the main force of the plastic industry. Naturally, the demand for chemical plastics will gradually decrease, which means that the demand for oil in the plastic industry will continue to decrease, and at the same time, the increasingly severe global oil crisis will be alleviated

at the same time, the production of corn plastics has also solved the global corn inventory problem, which can be described as killing two birds with one stone. In 2004, the global corn inventory was 111.71 million tons, and China's 33.05 million tons, accounting for one third of the world, second only to the United States, ranking second in corn reserves. Corn is different from other crops. After storage for one to two years, it will produce xanthozyme (a cancer treatment substance) and become inedible. Industrial use is the only way out

in China, 80% of corn is used for feed, and the added value is low. For China, solving the problem of stored corn is undoubtedly a major breakthrough to solve the three rural issues facing China

Young people face a lot of choices

the dilemma of price mass production

some people will ask: since corn plastic is so magical and has the advantages of degradability and pollution-free, why can't it be widely used and can't be seen in the market

it has been ten years since the birth of corn plastics. In the past ten years, only American nature works company has the production technology of corn plastics, namely "two-step process". It is learned that nature works of the United States is also the only enterprise in the world to produce corn plastic raw materials. At present, the price of corn plastic raw materials is about 3000 US dollars/ton, and the price of chemical plastic raw materials is about 1000 US dollars/ton

in terms of price, the price of corn plastic raw materials produced by nature works is three times of the market price of chemical plastic raw materials. According to the data provided by nature works, in 2004, nature works had an annual production capacity of 140000 tons, but the output was only 45000 tons. The enterprises that purchase corn plastic raw materials are mainly used to produce high-grade plastic products, biomedicine, textiles, etc., and a small part of them are used for industrial experiments

According to the analysis of nature works, the difficulty in popularizing corn plastics is mainly due to the complex production process of "two-step process", which makes its cost much higher than that of chemical plastics. At present, most of the companies that buy corn plastic from nature works are world-renowned multinational enterprises. For example, some restaurants of McDonald's in the United States began to use corn plastic drink cups; Coca Cola's soft drink packaging and so on. These well-known enterprises only use corn plastic products in a trial manner in some of their products

according to experts' analysis, after ten years of development, the technical indicators of nature works' corn plastics have been comparable to those of chemical plastics, but the price factor has always been that corn plastics are difficult to be widely used. Ren Jie told: "if you want to achieve mass production of corn plastic, the only way is to reduce the cost."

the so-called "one-step method" is to ferment corn into lactic acid and then directly make it into corn plastic particles. The "two-step process" of nature works is to ferment corn into lactic acid, and then produce the intermediate lactide, which is ring opened and polymerized into polylactic acid. "One step" simplifies the "two-step" process, which naturally reduces the production cost of corn plastic

the "one-step" process is applied to
