Plastics have come into our lives, but how to dispose of them after use is embarrassing. With a new technology in Shenzhen, you don't have to worry about it anymore. Because, these "plastic products" are made from degradable materials.
Yesterday, the reporter learned from Shenzhen Aobel Technology Co., Ltd. that the company has successfully completed the pilot test of the industrialization of PHAs (polyhydroxyalkanoates), which is a fully biodegradable material, and is actively preparing to build the first domestic 5,000 tons per annum The above fully biodegradable material production line.
Corn stalks change green film
“You see what is the difference between this film and ordinary film?†Yesterday, just entering the door of the Oberthur test room, the company’s chairman, Zhong Luhua, unfurled a film from a row of plastic products. This kind of "difficulty" was given to reporters.
Looking left and right, the reporter did not see any doorway.
“Don't look at this film that looks just like ordinary film. The raw materials it uses are all from crops and plants. After being discarded, they can be completely biodegraded into carbon dioxide and water, and 100% return to nature.†Zhong Luhua smiled. Mystery.
In the pilot room, small glass bottles are everywhere, filled with particles of different sizes and sizes. There is also an experimental vessel containing some white stuff like foam. The foam feels soft and does not smell any irritating odor. Zhong Luhua said that the particles in the glass bottle and the foam in the vessel are completely biodegradable materials—polyhydroxyalkanoate and its copolymer PHAs. The films and plastic bags that you just saw are those pressed from the degradable materials.
Biodegradable materials reduce costs
At present, many of the degradable plastics used in the Chinese market are mostly made by adding some photolytic materials or a small amount of starch to non-degradable materials and decomposing them into small powders. There is no real sense of degradation, and their environmental pollution and hazards remain. exist. At the same time, the plastics industry in China, which uses petroleum as raw material, has gradually reduced its petroleum resources, causing the cost of plastic products to increase steadily.
“Plastic bags and films made from PHAs can be degraded and become carbon dioxide and water even if they are discarded, and they will become necessary nutrients for crops again.†Aobaer’s technical staff said that PHAs products are biocompatible, Biodegradability, piezoelectricity, good use and processing performance, drawing, molding, hot injection molding, can replace most petroleum-derived plastics, can be widely used in agriculture, environmental protection, bio-chemical, micro-electric materials , energy, food packaging, agricultural film, medicine, medical materials and other fields.
In addition, the company produces raw materials that can completely degrade biomaterial PHAs, all from crops and plants, and its products return to nature after 100% of its life cycle, and the manufacturing cost is only 1/5 of that of petroleum plastics.
New technologies can increase income for farmers
"PHAs materials have the advantages of complete degradation and cost reduction. More importantly, they can replace agricultural oil with agricultural crops, produce various kinds of industrial materials, and achieve complete docking of agriculture and industry. To a certain extent, they solve the problem of 'three rural issues' in China and give farmers Bring huge economic benefits." Zhong Luhua said so.
Take a small city with an annual fiscal revenue of only 170 million yuan in remote areas of the Mainland as an example. The city grows potatoes all year round, extracting starch from it, 6 tons of potatoes can extract 1 ton of starch, and 3 tons of starch can extract 1 ton of polymer. That is, 18 tons of potatoes can extract 1 ton of polymer, which requires nearly 600,000 acres of potato production base. According to the calculation of 1 ton of potato for 400 yuan and 1 mu of potato for 3 tons, the cultivation of potatoes will enable local income of 720 million yuan. If a 100,000-ton PHAs base is put into production, then the per capita income of the city will increase to 3,200 yuan/year based on an average of 4.8 acres per capita.
According to Zhong Luhua, the next step will be to set up a production line in Ningxia or Shandong, and place downstream processing in Shenzhen.
Black Wolfberry King generally refers to more than 0.8 cm of black wolfberry, wild black wolfberry such a large very rare, high anthocyanin content, rich nutritional value.
Black wolfberry, flat and sweet, sweet and sweet, into the liver and kidney two meridian, have nourishing liver and kidney, bright eye nourishing, anti aging, strong muscles, blood nourishing eyes, moistening lung to stop coughing.

"Bier" and "Fu Fu" pointed out: Black wolfberry is good at nourishing essence. All generations of Chinese medical practitioners and regimen attach great importance to black wolfberry. "Compendium of Materia Medica" contains black wolfberry to cure 33 prescriptions for strengthening the body. Ge Hong, Tao Hongjing, Sun Simiao and other ancient medical circles are very fond of drinking black wolfberry wine. Our country also has the custom of making black wolfberry wine, and it is called "Laozi", which means remote aging. Black wolfberry, since ancient times has been used for the bright eye, "want to have a bright eye, often drink black wolfberry soup," so the people also called it "bright eye grass.
