Ichatshazelwa lihlabathi "Isithintelo sePlastiki” kunye “Ukuvalwa kwePlastiki” imithetho, ezinye iindawo zehlabathi sele ziqalisile ukumisela izithintelo ezinkulu zeplastiki kwaye imigaqo-nkqubo yokuvalwa kweplastiki yasekhaya iphunyezwe ngokuthe ngcembe. Imfuno yeeplastiki ezinokonakala ngokupheleleyo iyaqhubeka nokukhula. I-PLA yeplastiki eyonakaliswa ngokupheleleyo ineenzuzo ezibalaseleyo xa ithelekiswa nezinye iiplastiki ezonakeleyo, kwaye ngokuthe ngcembe iye yaduma.

Yintoni impahla ye-PLA?

I-PLA polylactic acid, ekwaziwa ngokuba yipolylactide, ibhekisa kwipolymer yepolyester efunyenwe ngokwenza ipolymerizing lactic acid njengeyona imathiriyeli ekrwada. Ngokuqhelekileyo yenziwe ngestatshi esicetywayo ngemithombo yezityalo ezivuselelekayo (ezifana nombona, i-cassava, njl.). Ludidi olutsha lwemathiriyeli ehlaziyekayo enokubola.

Kutheni le nto izinto zePLA zine-100% ezinokubola?

I-PLA sisixhobo sohlaziyo sesityalo esinokuhlaziywa kwe-biodegradability kwaye sinokutshatyalaliswa ngokupheleleyo yi-microorganisms kwindalo emva kokusetyenziswa.
I-Polylactic acid i-aliphatic hydroxy acid polymer, into enzima kwimo yeglasi kwiqondo lokushisa, kwaye iguqulwa ibe yi-carbon dioxide, i-CH4 kunye namanzi phantsi kokubola kwe-microorganisms. Yimathiriyeli eqhelekileyo enokubola ngokupheleleyo.

Ziziphi iingenelo zokusebenzisa imathiriyeli ye-PLA?

I-tableware ye-PLA ingaba yi-100% yokuchithwa kwi-carbon dioxide kunye namanzi kwindalo, ukuxazulula ingxaki yokungcola okumhlophe ukusuka kwingcambu, ukukhusela okusingqongileyo kunye nokufezekisa uphuhliso oluzinzileyo.

Okwangoku, iibhokisi zesidlo sasemini eziqhelekileyo ezilahlwayo ezinje ngeebhokisi zokuthatha, iibhokisi zokutyela, kunye neebhokisi zokutya zevenkile enkulu zenziwe ngezinto ezisekwe kwipetroleum, kwaye inkqubo yemveliso iya kuqulatha izongezo ezingaphezulu, ezinokubangela umhlaza emzimbeni womntu. Ukukhetha izinto ze-PLA zilungile kwimpilo yakho.

Ubume obungxamisekileyo bemo engqongileyo kunye nemigaqo-nkqubo: Ngokwezibalo ezingaphelelanga, ukukhutshwa kwekharbon dioxide yehlabathi kubikwa ukuba kunyuke ukuya kuma-60°C ngo-2030. Le yidatha embi kakhulu. IWorld Environmental Protection Organization ikwabongoza ngamandla amalungu ayo ukuba anikele ingqalelo kwimekobume. Ke ngoko, ngumkhwa ongenakuthintelwa wokutshintsha iiplastiki ezilahlwayo kunye ne-polylactic acid ephinda isetyenziswe kwi-dinnerware enokubola ngokupheleleyo.

I-PLA inokuhambelana kakuhle, ukuthotywa, iipropati zoomatshini kunye neempawu ezibonakalayo. Ifanelekile kwiindlela ezahlukeneyo zokucubungula ezifana nokubumba ukuvuthela kunye ne-thermoplastic. Kulula ukusetyenzwa kwaye isetyenziswe ngokubanzi. Umzi-mveliso wethu okwangoku uvelisa aMakhaya, njengezinto zetafile, izitya, iindiza, ukupakishwa, iikomityi, iibhokisi zesidlo sasemini, njl.
