Ipulasitiki ibalwe njengenye yezinto eziqanjiwe ezinkulu zekhulu lama-20. Ipulasitiki ifana nenkemba esika nhlangothi zombili. Nakuba kuletha ukunethezeka kithi, kuletha nomthwalo osindayo emvelweni.
Ukuze kuvinjwe ukungcoliswa kwabamhlophe, amazwe ahlukahlukene akhiphe uchungechunge lwemithetho elandelanayo. Ekuqaleni kuka-2020, i-China yakhipha "Imibono Ngokuqhubekayo Yokuqinisa Ukwelashwa Kokungcoliswa Kwepulasitiki". Ekupheleni kuka-2020, imboni yezokupheka kuyo yonke i-China izokwenqabela ukusetshenziswa kwezitsha zepulasitiki ezilahlwayo ezingaboli.
Njengamanje, kunezinhlobo ezintathu eziyinhloko zotshani esihlangabezane nazo emakethe:PP amagatsha,I-PLAutshani, futhiutshani bephepha.
Ukusuka kwesokunxele: utshani bephepha,I-PLAutshani, PP utshani
Ngenxa yokwehliswa kwesithunzi kwezinhlobonhlobo zotshani, sihlele umncintiswano wokucekelwa phansi kotshani.
Satshala utshani bezinto ezintathu ezihlukene enhlabathini ukuze silingise ukucekelwa phansi komquba wotshani bezinto ezihlukahlukene ngaphansi kwezimo zemvelo futhi sibone ukuthi kwenzekani kubo ngemva kwezinsuku ezingu-70:
ⅰ-PP utshani
Ngemuva kwezinsuku ezingama-70 zokucekelwa phansi komquba, ama-PP straws awazange ashintshwe.
ⅱ-I-PLA utshani
Ngemuva kwezinsuku ezingama-70 zokucekelwa phansi komquba, utshani be-PLA abuguqukanga kakhulu.
ⅲ-utshani lwephepha
Ngemuva kwezinsuku ezingama-70 zokucekelwa phansi komquba, ukuphela kotshani bephepha sekubolile futhi sekonakele.
Imiphumela yegeyimu :Ama-straw straws awine lo mzuliswano wokwehlisa isithunzi.
Senza ukuqhathanisa okulula kokusebenza kwemvelo kwamastraw amathathu:
| Into | PP utshani | I-PLA utshani | Utshani lwephepha |
| Ama-Raw material | Amandla ezinsalela | Amandla e-Bio | Amandla e-Bio |
| Ivuseleleka noma cha | CHA | YEBO | YEBO |
| Ukucekelwa phansi kwemvelo | CHA | YEBO kodwa kunzima kakhulu | YEBO futhi kulula |
