The use of waste straw as raw material will be promising
On August 18, Kaisei Biologics (688065.sh) released its 2021 semi-annual report.
During the reporting period, Kaisai achieved an operating revenue of 1.014 billion yuan, up 27.83% year on year.
It is reported that the efficient use of biological waste is one of the three strategies for the development of Kaisai Biology, the semi-annual report shows that the company is carrying out straw treatment and application in the production of lactic acid pilot experiment.
According to Kaisai, the industrial utilization of straw and other biomass waste has achieved stage results, and a demonstration project of 10,000 tons of lactic acid using straw as raw material is expected to be completed by the end of 21.
In the industrial utilization of straw, making raw material is one of the ways with the highest added value.
In early 2020, the National Development and Reform Commission and the Ministry of Ecology and Environment issued the Opinions on Further Strengthening the Control of Plastic Pollution, which set a "timetable" for the restriction of plastic products.
As the representative of polylactic acid materials made from corn and straw, bio-based materials with degradable function have quickly entered the public's vision.
The application of straw raw material is very rich, can be converted into a variety of chemicals, used in papermaking, textile, plate processing and chemical raw materials.
In recent years, in order to make the straw industry chain truly circulation unimpeded, new technologies and new attempts continue to emerge.
For example, Anhui BBCA Group will fertilizer straw waste into treasure, processing into shirts, clothing, wood tables and chairs, disposable masks and other straw products.
According to Li Rongjie, chairman of the company, the company uses the production process of polylactic acid, which can also be made into a variety of environmentally friendly plastics, instead of traditional chemical fibers and plastics.
Last year, Anhui BBCA signed up as a biodegradable tableware supplier for Beijing 2022 Winter Olympics and Paralympics, providing biodegradable tableware and related support services for the Beijing Winter Olympics.
At present, the application scenarios of straw as raw materials have been further broadened.
In addition to textile fabrics and tableware packaging, it can also be processed into tissue engineering scaffolds, fracture internal fixation materials, surgical sutures and other medical supplies.
With the continuous upgrading of the "plastic ban", the market demand for degradable materials represented by poly (lactic acid) increased substantially.
In order to ensure the supply of polylactic acid, it is necessary to cultivate corn, cassava and other raw materials on a large scale.
If using straw and other agricultural wastes to produce polylactic acid, not only does not exist the risk of "competing with the people for food", but also solves the pollution problem of straw burning.
In recent years, the utilization of straw as raw material has been paid attention to, and some straw utilization technologies have been planned and put into production.
● Recently, the Metabolomics research group of the Youth Research Institute of Chinese Academy of Sciences has successfully developed a new integrated biosaccharification (CBS) strategy of lignocellulose with complete intellectual property rights.
CBS uses a novel biocatalyst based on fibrosomes coupled with fermentable sugars for downstream applications, providing significant flexibility and cost advantages.
At present, the metabolite omics research group has built a 100-ton straw saccharification pilot pilot demonstration through cooperation with enterprises, which will achieve industrialization in 1-2 years.
● On August 10, 2021, Jinan Shengquan Group was officially listed on the main board of the Shanghai Stock Exchange, with an issue price of 24.01 yuan per share.
According to the prospectus, Shengquan has also dabbled in biomass chemical products, mainly made from agricultural by-products.
The company purified and efficiently utilized the three components of hemicellulose, lignin and cellulose in corn cob and straw, forming a biomass refining technology with independent intellectual property rights.
Meanwhile, lignin phenol and furfural were made from lignin and hemicellulocellulose to produce furan and phenolic resin, forming an integrated industrial chain of biomass chemical industry and synthetic resin industry, and realizing the recycling of plant straw.
● May 29, 2021, the groundbreaking ceremony of Ningbo Biodegradable new material Industrial Base project was held.
This project relies on the third generation of lactic acid preparation technology from Germany owned by Dehong Technology, and mainly takes straw and other cellulose and hemicellulost as raw materials for production.
With a total investment of about 5.1 billion yuan, the project will be constructed in three phases.
After completion, it will form a production base with annual output of 300,000 tons of lactic acid, 200,000 tons of polylactic acid and 100,000 tons of polylactic acid fiber with the third generation straw lactic acid as the core logo.
In January 2020, Jilin Hedi Technology Co., Ltd. was formally established in Dunhua city, Jilin Province.
As a high-tech enterprise, Hedi Technology focuses on the research and development, production and sales of long fiber and high filling bio-based composites.
The company will complete the annual production of 100,000 tons of straw and plastic materials and their products in Dunhua in three years, and the production is expected to be fully put into operation in 2022.
According to the introduction, since the national comprehensive utilization of straw pilot in 2016, the basic formation of fertilizer use mainly, raw material, base material for auxiliary development pattern.
At present, the comprehensive utilization rate of crop straw in China is 90%, which has successfully completed the targets of the 13th Five-Year Plan.
The utilization rate of straw fertilizer, base material and raw material was 51.2%, 2.43% and 2.47% respectively.
At present, the straw raw material utilization industry has developed rapidly, and the straw extraction polylactic acid technology has just entered the mass production stage.
In the 14th Five-year plan of the national comprehensive utilization of straw and the ban on plastic policies, the use of straw as raw material is still promising in the future.
