Kodi thumba lotha kuwola ndi chiyani?

1. Matumba owononga chilengedwe，Matumba owononga chilengedwe ndi matumba omwe amatha kuwola ndi mabakiteriya kapena zamoyo zina. Matumba apulasitiki pafupifupi 500 biliyoni mpaka 1 thililiyoni amagwiritsidwa ntchito chaka chilichonse.

2. Kusiyanitsa pakati pa "chowola" ndi "chopangidwa ndi manyowa"
Mwachidule, mawu akuti biodegradable ali ndi tanthauzo losiyana ndi manyowa. Biodegradable imangotanthauza kuti zinthu zitha kuwola ndi mabakiteriya kapena zamoyo zina, ndipo "compost" mumakampani opanga pulasitiki imatanthauzidwa ngati kuthekera kuwola m'malo ozungulira omwe amasungidwa kutentha ndi chinyezi cholamulidwa. Compost ndi kuthekera kuwola m'munda wa manyowa, zomwe zimapangitsa kuti zinthu zisawonekere bwino ndikuwola kukhala carbon dioxide, madzi, zinthu zopanda organic ndi biomass pamlingo wofanana ndi

Kuphatikizidwa kwa "zinthu zopanda chilengedwe" kunachotsa chinthu chomaliza chomwe sichinawonedwe ngati manyowa kapena humus, zomwe ndi zinthu zachilengedwe zokha. Ndipotu, muyezo wa xxx wofunikira kuti pulasitiki izitchedwa manyowa motsatira tanthauzo la ASTM ndikuti iyenera kutha pamlingo womwewo monga chinthu china chomwe munthu amadziwa kale kuti chigwiritsidwe ntchito popanga manyowa motsatira tanthauzo lachikhalidwe. Matumba apulasitiki amatha kupangidwa kuchokera ku pulasitiki wamba (monga polyethylene) kapena polypropylene ndikusakanizidwa ndi chowonjezera chomwe chimayambitsa kuwonongeka kwa polymer (polyethylene) kenako nkuwola chifukwa cha.
3. Zipangizo za thumba lotha kuwola
olimba komanso odalirika monga matumba achikhalidwe (makamaka a polyethylene). Matumba ambiri amapangidwanso ndi pepala, zinthu zachilengedwe, kapena polyhexanolactone. "Anthu amaona kuti kuonda ndi chinthu chamatsenga," ngakhale kuti mawuwa amagwiritsidwa ntchito kwambiri, malinga ndi RamaniNarayan, mainjiniya wa mankhwala ku East Lansing Michigan State University komanso mlangizi wasayansi ku Institute for Biodegradable Plastics." Pakadali pano ili ndi liwu lomwe limagwiritsidwa ntchito kwambiri komanso losagwiritsidwa ntchito molakwika mu dikishonale yathu. Mu Greater Pacific Waste Area, pulasitiki yoonda imasweka kukhala zidutswa zazing'ono zomwe zingalowe mosavuta mu unyolo wa chakudya podyedwa.
4. Kubwezeretsanso matumba owonongeka.
Zinyalala zomwe zili m'zomera nthawi zambiri zimatha kubwezeretsedwanso, koma zimakhala zovuta kuzikonza ndikuzibwezeretsanso mutazigwiritsa ntchito. Ma polima opangidwa ndi bio amatha kuipitsa kubwezeretsanso kwa ma polima ena odziwika bwino. Ngakhale opanga mapulasitiki osinthika a aerobic akunena kuti matumba awo amatha kubwezeretsedwanso, ambiri opanga mafilimu apulasitiki sangawalandire chifukwa palibe kafukufuku wa nthawi yayitali wokhudza kuthekera kwa zinthu zobwezeretsedwanso zomwe zili ndi zowonjezerazi. Kuphatikiza apo, Institute for Biodegradable Plastics (BPI) idati mapangidwe a zowonjezera m'mafilimu osungunuka amasiyana kwambiri, zomwe zimayambitsa kusiyana kwakukulu pakubwezeretsanso.
