Biofermentation technology and green manufacturing.

Microbial fermentation technology channel news: In the past few decades, the traditional manufacturing industry in the process of transforming resources into products, consumed a large number of limited resources, and caused serious environmental pollution, green manufacturing has become an important topic of sustainable development in the 21st century.
Biofermentation as an important part of green manufacturing, after more than 20 years of development, its product quality, technological innovation capacity and comprehensive utilization of resources have been comprehensively improved, the development focus has also shifted from the past focus on quantity increase to qualitative improvement, efficiency improvement, expand the depth and breadth of comprehensive utilization of resources, as well as the implementation of all-round green production.
the overall development momentum statistics show that from 2011 to 2013, China's fermentation industry's total output of major products remained stable growth, with an average annual growth rate of 4.4%.
2013, the total output of major products in the fermentation industry was 24.29 million tons, up 2.7% YoY, and the total industrial output value was 278 billion yuan, up about 3.0% YoY.
At present, due to the saturation of the traditional bulk product market, production enterprises have begun to develop and produce new products, product varieties continue to increase, such as small varieties of amino acids, pharmaceutical preparations, new enzymes, etc., in order to extend the industrial chain, improve the level of comprehensive utilization, create new economic growth points.
"12th Five-Year Plan" period, the concentration of biofermentation industry is also increasing, the geographical location of production enterprises with the continuous changes in production cost factors have been transferred, and gradually to raw material supply and energy prices lower, convenient transport areas.
as an example, MSG production enterprises have been to corn-rich Xinjiang, Inner Mongolia, Heilongjiang and other regions.
, but also the results of eliminating backward production capacity are more significant.
Since 2011, the Ministry of Industry and Information Technology has issued an annual task notice to eliminate backward production capacity, so far, MSG industry eliminated a total of 487.8 million tons / year of backward production capacity, citric acid industry eliminated a total of 1755 million tons / year of backward production capacity.
years, China's fermentation industry has invested a lot of money in research and development and trial operation of energy-saving, water-saving and other technologies to improve the conversion rate of raw materials and comprehensive utilization rate, reduce pollution levels.
advanced technology has been widely used in the industry, promoting the green and healthy development of the biofermentation industry.
e.g. high-performance temperature-sensitive bacteria targeted breeding, domestication and fermentation process control technology, not only can reduce glutamate tons of product food consumption and energy consumption, but also by increasing acid yield and glycate conversion rate to reduce water consumption, reduce chemical oxygen demand (COD) production purposes.
The new concentrated continuous electric extraction process replaces the isoionization process in traditional MSG production, solves the problem of producing a large number of high-concentration ionization wastewater in the extraction section of MSG industry, uses automatic heat pump equipment to recycle the secondary steam in the crystallization process, and can also achieve the goal of saving steam and reducing energy consumption.
In addition, the new chromatography separation and extraction of citric acid technology used in starchy as raw materials for the production of citric acid enterprises, not only completely solve the traditional calcium salt precipitation method to produce a large amount of calcium sulfate environmental problems, but also in raw material consumption, energy consumption and end waste generation has been greatly improved.
the new situation, biofermentation not only makes important contributions to the food industry, but also provides strong support for feed, medicine, textile, papermaking, energy and other industries.
, however, there are still many challenges as the overall strength of the industry leaps to a new level.
is a gradual slowdown in the pace of development.
To this, the biofermentation industry must be fully prepared, do not fantasize that the past era of high-speed growth will come again, to adapt to the slowdown in the growth rate of this external environment changes, focus on the mode of transition, adjustment of structure and industrial upgrading.
is that the proportion of low- and medium-grade products is too high, some products appear structural surplus, the task of eliminating backward production capacity is heavy.
mainly lies in the lack of innovation ability, blind follow-up and imitation, low-level repeated construction, homogenization is serious.
overcapacity also shows that the industrial supply capacity can not adapt to and meet the changes in market demand, speeding up the upgrading of supply capacity is urgent.
third is the increasing cost of factors of production, resources, environment, energy requirements continue to increase, industry profits.
this end, enterprises must develop high value-added products, improve the productivity of all factors, enhance the value of the industrial chain, improve the level of output, reduce the overall cost as the main direction.
fourth is the "going out" strategy is imperative.
, fermentation industry can represent the Chinese national brand of enterprises are rare, most enterprises in a limited to domestic competition in the enterprise group, will inevitably lead to the situation of industry overcapacity.
, the "going out" strategy is the need for Chinese enterprises to develop space, not only to make use of sufficient raw materials abroad, but also to bring China's advanced manufacturing technology and management experience abroad.
In the fermentation industry is facing a new stage of development, we should be soberly aware that the biofermentation industry previously rely on high input, high energy consumption, low-cost growth model, has been unsustainable, accelerate the transformation of growth mode, optimize structural adjustment, accelerate the process of product and industrial chain high-grade, transformation and upgrading, and comprehensively improve the quality and overall level of the biofermentation industry is the industry's top priority.
industry development advice Biofermentation industry after decades of development, although has formed a stable and healthy development situation, but a very small number of enterprises still have bad business behavior.
in order to standardize the development of the industry and promote the healthy progress of the industry, it is necessary to establish and improve the relevant laws and regulations, strengthen the self-discipline of the industry, and severely punish illegal acts.
In addition, biofermentation technology is a collection of biology, chemistry and engineering in one of the contemporary cutting-edge technology, bio-fermentation industry is also a high-tech industry, so we should deeply understand the development trends and cutting-edge technology of the bio-fermentation industry at home and abroad, firmly grasp the core of technological innovation, relying on technological progress.
, the cost of energy consumption in the biofermentation industry accounts for about 20% of the total production cost, and the task of energy conservation and emission reduction is heavy.
, the industry should earnestly implement the resource-saving and environment-friendly development strategy, and vigorously promote the green low-carbon circular development and clean production strategy.
Finally, more than 85% of the raw materials used in the biofermentation industry are corn, which is relatively single and subject to a series of problems such as origin, price, supply and transportation of raw materials, so it is imperative to vigorously develop the application of non-food raw materials.
