On two meetings, 7 propose talk on behalf of two meetings: Industry of data of degradation of content of fast complete look unfamiliar should be so dry! Lv Liang result: Disturbed market of ” of “ bogus degradation, should accelerate promotion complete degradation plastic 　 Yuan Zhimin: The proposal gnaws ”“ of degradation of “ smooth oxygen model agent ” to wait include wash out Zheng Yueming of 　 of catalogue item: Degradation is plastic low end is produced can superfluous, strengthening core technology to tackle key problem is crucial 　 Shao Changjin: Use special fund to wait for PBAT, PLA include core to tackle key problem technical 　 Shao Zhiqing: Strengthen Cao Amin of plastic 　 of ” of degradation of bogus of superintendency blow “ : Perfect and plastic pollution administers code, accelerate new material of green low carbon to replace applied 　 Li Jinghong: Use safe “ appearance to soil”However, different sound exists forever on, shi Shangjiang oppugns industry of acoustical 　 degradation is the Spring Festival as before general lively, recently, small write the article that received the antrum doctor that comes from science and technology of family name of peaceful wave antrum, proving PBAT is not complete biology degradation. Small make up can't help thinking, if PBAT is like character of antrum doctor place, is degradation of that blatant whole live thing in is misdirect plastic industry? Hereby transmit looks to everybody, article content does not represent this public date point of view, explain hereby.

In addition, oppugn PLA but the article of degradation sex has a story early: A few experts consider to discover, in specific water system, PLA can complete degradation. The specific water system that this expert group indicates, below room temperature condition, wearing the Hai Sha of the river with north, sea mud of Ning Bo, in the aquarium that north wears the seawater of the river to be water system, the experiment observes discovery, the PLA film of biaxial stretching can complete degradation. The seawater of additionally a few experts experiments, discover PLA is basic cannot degradation. On November 17, 2020, the biology degradation colophony that manage of Chinese Academy of Sciences changes Ji Junhui of technical institute researcher to be held in association of Shenzhen city high polymer expresses on the seminar, “ and terrestrial soil are different, microbial quantity is few in seawater, and briny temperature is lower also, biology degradation is plastic cannot resemble be on land in seawater same degradation, perhaps say to cannot be inside a long time in seawater by degradation. ”Many research conclusion: PLA is basic in seawater not college of agriculture of Greek 2010 Athens uses degradation 　 　 Mediterranean actual soil does PLA live thing but the degradation with plastic degradation experiments, the time of 11 months is partial physics disintegrate and partial disintegrate only. Soil of nature of imitate of university of science and technology of industry of the Na Lin in 2014, the polybag that pledges PLA material is buried in imitate nature soil, after 12 months, its quality only loss 0.23% , have degradation hardly. Picture 　 environment is the main factor that affects performance of degradation of biology degradation material, briny environment and soil or compost environment differs completely. Strong, tall salt and high pressure are microtherm, fluidity the main characteristic of ocean environment. In ocean environment, microbial majority distributings in inshore area, the microbial content in high seas area is inferior, do not have even. The experiment that Germany strode Loewe spy university 400 days 2017, all sorts of biology but degradation is plastic come true in industrialized compost but degradation, place inside seawater and fresh water, PLA makes an appointment with 0.5% quality loss only after. 2017, manage of Chinese Academy of Sciences turns place and project plastic engineering research center organizes nearly 10 doctors to study seawater but degradation is plastic. This research result " polyester of typical biology degradation is in the degradation function in seawater " was published in October 2020 " journal of functional high polymer " on, (get textual ask ” of degradation of seawater of backstage reply “ ) , the author is Wang Gexia, Huang Dan, Zhang Wei, Ji Junhui, the article points out in system of 6 kinds of different water, PLA is basic not degradation. Small make up think: PBAT, PLA but degradation is plastic and reasonable below the compost condition that consider, through sufficient time, should reach different degradation level, but to temperature, humidity, bacterium group the condition should have asking certainly. Have doubt of the expert inside course of study: Can demote plastic expand blindly, whether to put in great and potential risk? Ba Sifu is in 20 mastered before New Year more but technology of degradation polyester industrialization reachs many tons 10 to produce can, to why be Europe however inside 20 years to magnify its 1 million tons of dimensions? Planned inside 5 years many tons 200 can fall depolymerization ester project, the expert inside course of study expresses concern: Prospective 5-10 year, whether already ready enough land and fertilizer, use 10 thousand tons at degradation to exceed 200-300 / year but is degradation plastic? Decompose inside 1 year rate is there many tall? Whether can produce young member to remain in noxiousness, soil contamination problem? . . . . . . We had not gotten ready it seems that. . . . . . . . .
