Kodi thumba la biodegradable ndi chiyani

1.Biodegradation bag，Zikwama za biodegradation ndi matumba omwe amatha kuwola ndi mabakiteriya kapena zamoyo zina.Za 500 biliyoni mpaka 1 thililiyoni matumba apulasitiki amagwiritsidwa ntchito chaka chilichonse. Matumba a biodegradation ndi matumba omwe amatha kuwola ndi mabakiteriya kapena zamoyo zina. Pafupifupi 500 biliyoni mpaka 1 thililiyoni matumba apulasitiki amagwiritsidwa ntchito chaka chilichonse.
2.Kusiyanitsa pakati pa "biodegradable" ndi "compostable"
Mwachidule, mawu akuti biodegradable ali ndi tanthauzo losiyana ndi kompositi.Biodegradable amangotanthauza kuti zinthu zitha kuwola ndi mabakiteriya kapena zamoyo zina, ndipo "kompositi" mumakampani apulasitiki amatanthauzidwa ngati kuthekera kowola m'malo a aerobic omwe amasungidwa pamalo enaake. Kutentha kolamulidwa ndi chinyezi.Compospost ndi kuthekera kwa biodecompose m'munda wa kompositi, kupanga zinthu zosawoneka bwino ndikuwola kukhala carbon dioxide, madzi, inorganic compounds ndi biomass pamlingo wogwirizana ndi

Kuphatikizika kwa "inorganic material" sikunaphatikizepo chinthu chomaliza kuti chisatengedwe ngati kompositi kapena humus, yomwe ndi zinthu zachilengedwe zokha. mlingo ngati chinthu china chimene munthu amadziwa kale kuti kompositi pansi pa tanthauzo lachikhalidwe. Matumba apulasitiki amatha kupangidwa kuchokera ku polima wamba wa pulasitiki (mwachitsanzo, polyethylene) kapena polypropylene ndikusakaniza ndi chowonjezera chomwe chimayambitsa kuwonongeka kwa polima (polyethylene) kenako ndikuwonongeka chifukwa cha.
3.Zinthu za thumba biodegradable
zolimba monga zolimba komanso zodalirika monga matumba achikhalidwe (makamaka polyethylene). Matumba ambiri amapangidwanso ndi mapepala, zinthu zakuthupi, kapena polyhexanolactone. "Anthu amaona kuti biodegradable ndi chinthu chamatsenga," ngakhale kuti mawuwa amagwiritsidwa ntchito kwambiri, malinga ndi RamaniNarayan, katswiri wa sayansi ya mankhwala ku East Lansing Michigan State University komanso katswiri wa sayansi ku Institute for Biodegradable Plastics. ndi mawu ogwiritsidwa ntchito molakwika mu dikishonale yathu.Mu Greater Pacific Waste Area, pulasitiki yosawonongeka imasweka kukhala tizidutswa tating'ono ting'ono tomwe titha kuloŵa m'maketani a chakudya mwa kudyedwa.
4.Kubwezeretsanso matumba a biodegradable.
Zinyalala zomwe zili muzomera zimatha kubwezeretsedwanso, koma zimakhala zovuta kuzisintha ndikuzikonzanso zikatha kudyedwa. Ma polima opangidwa ndi bio amatha kuyipitsa kukonzanso kwa ma polima ena odziwika. obwezeretsanso sangawavomereze chifukwa palibe kafukufuku wanthawi yayitali pa kuthekera kwa zinthu zobwezerezedwanso zomwe zili ndi zowonjezera izi.Kuphatikiza apo, Institute for Biodegradable Plastics (BPI) inanena kuti mapangidwe a zowonjezera m'mafilimu opangidwa ndi okosijeni amasiyana mosiyanasiyana, zomwe zimabweretsa kusinthasintha kwakukulu. mu ndondomeko yobwezeretsanso.
