jihepackage, A new product, the level of industrial production depends on the needs of the community, performance and cost, as well as alternative products, social effects and environmental issues are also important factors that can not be ignored. Its market dress bag cultivation also need to have a process, and the development of bio-based products is no exception.
Obviously, biological and chemical play a role in promoting industrial shelf hanging organizer technological progress and industrial adjustment, especially green chemical industry, can be described as a green chemical "yeast".
Scale will drive the technology to reduce costs
"Overall, the biggest disadvantage of bio-based products is high prices." Chen Hong Zhang, a researcher with the Chinese Academy of Sciences Institute of Process Engineering, for example, ordinary polyethylene (PE) shopping bags two shopping bag or three cents, while the bio-plastic shopping bag will have 1 to T-shirts, a cotton T-shirts, ranging from tens of dollars to a more than a hundred dollars, then you is not a few hundred dollars, while the one containing the fiber of polylactic acid (PLA, bio-based materials) 2 million; sold for 1,000 yuan.
In his view, the most effective way to reduce prices is the large-scale production, and large-scale production will need to have a certain market. Technology development and scale will reduce the cost of bio-based products, to improve its competitiveness, new products, new technology development have a small to large process, with the technology and the market has become more sophisticated, the scale is an inevitable trend. , which will benefit the development of bio-based products.
"Although China is the largest producer of bio-based materials, but mostly for export and domestic use of bio-based materials, there is a lot of room." Chan Kwok-keung, professor at the School of Life Sciences, Tsinghua University, said that relevant departments of the government should introduce policies to encourage biological The development of the base material, such as the tax increase of the non-degradable materials for bio-based and biodegradable materials to reduce taxes, and even give subsidies to promote the development of the industry as a whole.
Rely on renewable materials Breakout
With the increasing depletion of non-renewable resources such as oil, raw materials became a petroleum-based product producers must pay attention to the problem of the industry is highly dependent on oil resources, the current uncertainty in the international crude oil price volatility, is undoubtedly the industry's disaster , fluctuations in the price of raw materials is the greatest threat facing the industry.
At the same time, petroleum-based products from raw material extraction, refining of raw materials, production, product consumption throughout the process, on the environment caused a great deal of damage. The inevitable trend of the face of the enormous pressure of the shortage of resources, ecological and environmental protection an urgent requirement, as well as social and economic sustainable development, the only way to resolve this outstanding issue, that is, the development of bio-based products as raw materials to renewable biomass resources.
For example, crops and crop stalks, comes directly from solar energy, carbon dioxide and water. The main raw material of the bio-plastic derived from plant materials such as corn starch, as raw materials directly from the plant, and the plant's growth process is a carbon neutral process, coupled with this part of the carbon emission reduction, bio-plastics in the full life cycle carbon emissions of only 20% of the petroleum-based plastics, is a typical low-carbon material.
At present, China's bio-based materials industry technology achieved significant results, such as biodegradable bio-based plastics, wood-based plastics, polymerization The large molecular polylactic acid, agricultural plastic film, such as a large number of proprietary technologies. National wood-plastic heat is gradually on the rise, the annual sales of wood products has exceeded 20 million tons, and the annual growth rate of more than 20% of high-speed growth. Bio-based materials as alternative to the upgrading of petroleum-based materials, is the direction of the development of efficient, high value-added, environmentally friendly, standardization toward green resource utilization characteristics.
Foreseeable market
Chen Hong Zhang also talked about the use of biological materials as raw materials is not a new thing, after the chemical and materials industry has long been in use biological or agricultural products as raw materials for production. Only in the early 20th century, the emergence of synthetic resins and chemicals, product performance bio-based materials than synthetic materials out of the market before. With the development needs of the low-carbon economy, the raw material price fluctuations, technological improvement in the performance of bio-based materials, bio-based materials again surfaced market.
In 2011, the North American construction industry, bio-renewable chemicals and materials market to reach $ 5.77 billion. Insulation materials market is the largest, the development of the most mature, accounting for 45.5% of the market share; spray polyurethane foam is nearly 10 years, the only new products. Wood-plastic composites market share of 41.4%, bio-based architectural coatings accounted for 10.3%, accounted for only 2.8% of bio-based adhesives. The next major growth opportunities in the market is in the early development of bio-based architectural coatings and bio-based adhesives. And a further breakthrough in the technology industry breakthrough.
European Bioplastics Association, the latest statistics show that in 2010 the global bioplastics production of 70 million tons, exceeded 100 million tons in 2011, estimated global bioplastics annual output will reach 170 million tons in 2015. Europe has become the world's largest consumer market of bioplastics.
Life and life of the world's largest bioplastics manufacturers naphthalene Qi Woke (NatureWorks), the current annual production capacity has reached 140,000 tons. Mai Lian Technology, Inc. (Myriant) in Louisiana in early 2011 started construction of the world's largest bio-based succinic acid plant capacity of over 10,000 t. After ten years of development, according to information provided by the China Plastics Processing Industry Association, our polylactic acid, polyhydroxyalkanoates, polybutylene succinate and other varieties of industrial production have achieved.
