Iminyaka engama-200 yokwehlisa isithunzi imizuzu engama-20 kuphela yokusetshenziswa ngokwesilinganiso.Utshani yinto encane esetshenziswa kakhulu ezindaweni zokudlela.Kuyinto eyasungulwa eMesopotamiya esongela ikusasa namuhla.Njengama-swabs kakotini, utshani yimikhiqizo yepulasitiki esetshenziswa kanye.Uma lezi zinto zingase zibonakale zingabalulekile kuwe, zimelela u-70% wemfucuza engcolisa izilwandle.I-European Union yenze isibopho sezombangazwe sokuqeda utshani bepulasitiki ngo-2021. Nokho, lesi sibopho asiyixazululi ngokugcwele indaba yepulasitiki.Singaluqala kanjani ushintsho ekuphileni kwethu kwansuku zonke?Uzothola kulesi sihloko izizathu zokuthi kungani ushintshela kuutshani obubolayoyinkinga ebalulekile.

Utshani bokuqala emlandweni

Ukusetshenziswa kotshani, phela, kulula kakhulu.Kuyinduku eyicylindrical egwazwe phakathi nendawo yayo kuzo zombili iziphetho.Isintu siyisebenzisele ukuphuza uketshezi kusukela ngesikhathi samaSumer eMesopotamiya.Utshani bokuqala emlandweni baqala ukutholwa ngenkulungwane yesine BC.Isibonelo esidala salokho okufana nezinhlayiya zethu zamanje sitholakala ku-Idolobha lasendulo laseSumeri i-Uri.Utshani butholakala ethuneni lomuntu omkhulu womphakathi waseSumeriya, iNdlovukazi uPuabi.

Kungani utshani unaleli gama?

Ngesikhathi sokuziphendukela kwemvelo, utshani buthatha ifomu elihluke ngokuphelele.Ngekhulu le-19, amadoda ayesebenzisa utshani be-rye ukuze bamunce uketshezi esiphuzweni sabo.Ngempela, utshani ngaleso sikhathi babulula ukutholakala, bungaduli, bukwazi ukumelana ngokwanele futhi bungenamanzi ukuze bufeze indima yabo.Isiqu ngokwemvelo sithatha igama lotshani ngoba amadoda avele ayisebenzisele ukuphuza.Ukuze uthole okunye, bekufanele nje uthatheizinhlanga zotshani ezindlebeni zabo.

utshani obulahlwayo obubolayo

Njengotshani lukakolweni, ezinye izinto zenza utshani obubolayo obusetshenziswa kanyekanye.Lokhu kunjalo, isibonelo, ama-straws enziweumoba, izinhlanga ezenziwe pasta, iphepha, amakhadibhodi or izinhlanga ezidliwayo.Uma lezi zamuva zinesici sokudlala, ezimelana kakhulu yi-PLA straws.

PLA utshani biodegradable

Utshani be-PLA obubolayo buyakwazi ukuvundisa.I-PLA iyi-bio-polymer eyenziwe ngengxubevange yezitashi zezitshalo ezihlukene, ikakhulukazi isitashi sombila.Kuyisitashi esivuselelekayo kalula kanye ne-100% yezinto eziphilayo ezingaboli kahle ezinempilo emvelweni.Yonke into emayelana notshani be-PLA ingcono emvelweni kuze kube sekupheleni kwayo, ekhipha amagesi abamba ukushisa amancane kunokukhiqizwa kotshani bezimboni.

Uhlobo lwe-PLA yotshani obubolayo esikunikezayo, isibonelo, luqinile futhi luyavumelana nezimo.Ayinaphunga futhi imelana namazinga okushisa aphansi.Ama-PLA straws ethu atholakala ngosayizi abahlukene, umumo futhi angabonisa namalogo.Lokhu kwenza imodeli yethu yotshani ye-PLA ifanele futhi ukuvundisa kwezimboni.
