1. Palasitika biodegradable
Biodegradable plastics e faasino i palasitika o latou faʻailoga eseese o faʻatinoga e mafai ona fetaui ma manaʻoga faʻatino, o faʻataʻitaʻiga o faʻatinoga e le suia i le taimi o le fata, ma e mafai ona faʻaleagaina i vaega e le faʻaleagaina ai le siosiomaga i lalo o le aafiaga o le siosiomaga pe a uma ona faʻaoga. Fa'avasegaina o palasitika fa'aleagaina. E tusa ai ma le faiga faʻaleagaina, o palasitika faʻaleagaina e mafai ona vaevaeina i ni vaega se fa: palasitika olaola, palasitika photodegradable, faʻataʻitaʻiga ma palasitika faʻaleagaina, ma palasitika vai. E tusa ai ma le faʻavasegaina o mea mataʻutia, e mafai ona vaevaeina palasitika faʻaleagaina i palasitika biodegradable ma palasitika faʻaleagaina faʻavae suauʻu. Tulaga lelei o palasitika fa'aleagaina. O palasitika biodegradable o loʻo i ai o latou lelei i tulaga o faʻataʻitaʻiga faʻatinoga, faʻatinoga, faʻaleagaina, ma mataupu saogalemu. e tusa ai ma le fa'atinoga, o palasitika fa'aleagaina o lo'o i ai fa'ai'uga fa'atinoga o fa'aoga tutusa ma fa'atinoga tumama e pei o palasitika masani o le ituaiga tutusa; i le tulaga o le faʻaleagaina A maeʻa ona faʻaaogaina, e mafai ona faʻaleagaina vave palasitika faʻaleagaina i lalo o le aafiaga o le siosiomaga faʻanatura ma liliu atu i ni vaega poʻo ni kasa e le oona e faigofie ona faʻaaogaina e le siosiomaga faʻanatura, faʻaitiitia ai le aʻafiaga o le siosiomaga masani; e tusa ai ma mataupu tau le saogalemu, palasitika fa'aleagaina O vaega po'o toega na fausia i le faagasologa o le fa'aleagaina o le a le fa'aleagaina ai le siosiomaga fa'anatura ma o le a le afaina ai le ola o tagata ma isi meaola. O le fa'alavelave tele i le suia o palasitika fa'aleaganu'u i lenei la'asaga, o le fa'aletonu fo'i o palasitika fa'aleagaina, o le tau o a latou oloa e maualuga atu nai lo le ituaiga palasitika masani po'o palasitika toe fa'aaogaina.
2. Palasitika toe fa'aaogaina
Palasitika toe faʻaaogaina e faʻatatau i mea faʻapipiʻi palasitika e maua pe a maeʻa le faʻaaogaina o palasitisi otaota e ala i auala faʻaletino poʻo vailaʻau e pei o le muaʻi togafitia, faʻafefeteina granulation, suiga, ma isi. e mafai ona na'o le fa'agaioia o vaega fa'apitoa o meatotino palasitika e tusa ai ma mana'oga fa'asologa eseese o fa'atinoga, ma maua ai oloa fa'atatau. Afai lava e le maualuga tele le tele o le toe fa'aaogaina, e mafai e palasitika toe fa'aaogaina ona fa'amautinoa le tutusa o fa'ailoga fa'atino e pei o palasitika masani, po'o mea toe fa'aaogaina e mafai ona fa'afefiloi ma mea fou e fa'amautu ai fa'ailoga fa'atinoga. Ae peita'i, a mae'a ta'amilosaga se tele, o fa'ailoga fa'atinoga o palasitika toe fa'aaogaina e fa'aitiitia tele pe le mafai ona fa'aaogaina.
3. Palasitika pK toe fa'aaogaina
E tusa ai ma faʻatusatusaga, palasitika faʻaleagaina e sili atu ona mautu le faʻatinoga ma faʻaititia le tau toe faʻaaogaina. Latou te maua le avanoa e sui ai le afifiina, ata tifaga mulch faʻatoʻaga ma isi talosaga e faʻapuupuu taimi faʻaoga ma e le mafai ona tuʻueseese ma toe faʻaaogaina; a'o palasitika toe fa'aaogaina o lo'o i ai O le tau maualalo ma le tau fa'agaioiga e sili atu ona lelei i vaega fa'aoga e pei o mea e mana'omia i aso ta'itasi, mea faufale, ma masini eletise e umi le tautua ma e faigofie ona fa'avasega ma toe fa'aoga. E felagolagoma'i le tasi i le isi. O le pa'epa'e pa'epa'e e masani lava ona sau mai le fale fa'apipi'i, ma palasitika fa'aleagaina e tele le avanoa e ta'alo ai. Faatasi ai ma le alualu i luma o faiga faʻavae ma faʻaitiitiga tau, o le pisinisi palasitika faʻaleagaina o loʻo i ai le tele o faʻamoemoega i le lumanaʻi. I totonu o fale faʻapipiʻi, ua uma ona faʻamautuina le suia o palasitika biodegradable. O palasitika e iai le tele o faʻaoga, ma o pisinisi eseese e iai tulaga eseese mo palasitika. O tulaga manaʻomia mo palasitika i pisinisi e pei o taavale ma mea faigaluega a le fale e umi ma faigofie ona vavae ese, ma faʻaaogaina palasitika taʻitasi i le tele o mea, o lea e malosi tele ai le tulaga o palasitika masani. I totonu o fale gaosi oloa e pei o pusa pusa palasitika, pusa meaʻai vave, ata tifaga mulch faʻatoʻaga, ma faʻamatalaga faʻaalia, ona o le faʻaogaina o monomers palasitika e maualalo ma faigofie ona faʻaleagaina, e le mafai ona vavaeeseina lelei. O le mea lea e mafai ai ona avea palasitika leaga ma suitulaga mo palasitika masani i totonu o nei alamanuia.
Palasitika biodegradable o se vaifofo sili atu ona lelei i le paʻepaʻe filogia nai lo le toe faʻaaogaina o palasitika. 59% o pa'epa'e filogia e sau mai le afifiina ma fa'ato'aga mulch oloa palasitika. Ae ui i lea, o palasitika mo lenei ituaiga o faʻaoga e mafai ona lafoai ma faigata ona toe faʻaaogaina, e le talafeagai ai mo le toe faʻaaogaina o palasitika. Na'o palasitika fa'aleagaina e mafai ona fo'ia le fa'afitauli o le filogia papa'e. Se'i vagana ai palasitika e fa'atatau i le masoa, o le tau fa'atau atu o isi palasitika fa'aleagaina e 1.5 i le 4 taimi nai lo palasitika masani. E mafua ona o le gaosiga o palasitika faʻaleagaina e sili atu ona lavelave ma e manaʻomia ai le faʻaaogaina o biomolecules masani taugata mo le polymerization, lea e faʻateleina ai tau gaosiga. I alamanuia e maaleale i le tau ma le faatinoga, o palasitika masani o loo faatumauina pea o latou tulaga lelei i le tulaga o le lapopoa, tau ma le faatinoga atoatoa, ma o lo latou tulaga e tumau mausali i se taimi puupuu. O palasitika biodegradable e masani lava ona suitulaga i pisinisi palasitika masani o loʻo faʻauluina e faiga faʻavae ma e maualalo le tau.
