I-Starbucks ikhupha i-biodegradable 'i-grounds tube' eyenziwe nge-PLA kunye nebala lekofu.
Ukuqala nge-22 ka-Epreli, i-Starbucks iya kuphehlelela iindiza ezenziwe ngeendawo zekofu njengezinto eziluhlaza kwiivenkile ezingaphezu kwama-850 eShanghai, ziyibiza ngokuba "zingca zengca", kwaye iceba ukugubungela ngokuthe ngcembe iivenkile kwilizwe liphela ngonyaka. Ngokutsho kwe-Starbucks, "ityhubhu ye-residue" yi-bio-explainable straw eyenziwe nge-PLA (i-polylactic acid) kunye neendawo zekhofi, ezithobisa ngaphezu kwe-90% kwiinyanga ze-4. Iindawo zekofu ezisetyenziswe kumququ zonke zitsalwe kwikofu ye-Starbucks. sebenzisa. "I-tube ye-slag" inikezelwe kwiziselo ezibandayo ezifana neFrappuccinos, ngelixa iziselo ezishushu zinezivalo zazo ezilungele ukusela, ezingadingi iindiza. -
Alpha-olefins, polyalpha-olefins, metallocene polyethylene!

Okwangoku, iUnited States, iCanada, iJamani, iNeth... -
Yintoni i-HDPE?
I-HDPE ichazwa ngoxinaniso olukhulu okanye olulingana no-0.941 g/cm3. I-HDPE ineqondo eliphantsi le-branching kwaye ngaloo ndlela inamandla e-intermolecular kunye namandla okuqina. I-HDPE inokuveliswa nge-chromium / i-silica catalysts, i-Ziegler-Natta catalysts okanye i-metallocene catalysts. Ukungabikho kwe-branching kuqinisekiswa ngokukhethwa okufanelekileyo kwe-catalyst (umzekelo, i-chromium catalysts okanye i-Ziegler-Natta catalysts) kunye neemeko zokusabela. I-HDPE isetyenziswa kwiimveliso kunye nokupakishwa okufana neejagi zobisi, iibhotile zokucoca, iibhafu zemajarini, izitya zokulahla inkunkuma kunye nemibhobho yamanzi. I-HDPE ikwasetyenziswa ngokubanzi kwimveliso yomlilo. Kwiityhubhu zobude obuhlukeneyo (kuxhomekeke kubukhulu be-ornance), i-HDPE isetyenziselwa ukutshintshwa kweetyhubhu zodaka zekhadibhodi ezinikezelweyo ngenxa yezizathu ezibini eziphambili. Enye, ikhuseleke kakhulu kunobonelelo...
