Faatasi ai ma le atinaʻeina o le tamaoaiga ma le faʻaleleia atili o le soifuaga o tagata, o loʻo faʻateleina le manaʻoga mo oloa palasitika i lea aso ma lea aso, ma o le "paʻepaʻe paʻepaʻe" o loʻo aumaia e le palasitika ua faʻateleina ma sili atu ona ogaoga.O le mea lea, o su'esu'ega ma atina'e o palasitika fou fa'aleagaina e avea ma auala taua e togafitia ai fa'afitauli tau le siosiomaga.Polymer plastics e mafai ona faʻaleagaina i lalo o le tele o tulaga, ma faʻaleagaina vevela e tupu i lalo o le gaioiga o le vevela.Faʻaleagaina faʻainisinia e tupu i lalo o le gaioiga o le malosi faʻainisinia, faʻaleagaina faʻamaʻi i lalo o le gaioiga o le okesene, ma le faʻaleagaina o meaola i lalo o le gaioiga a vailaʻau vailaʻau.Palasitika faʻaleagaina e faʻatatau i palasitika e faigofie ona faʻaleagaina i le siosiomaga faʻanatura e ala i le faʻaopoopoina o se aofaʻi o mea faʻapipiʻi (e pei o le starch, starch faʻaleleia poʻo isi cellulose, photosensitizers, biodegraders, ma isi) i le gaosiga o le gaosiga.
E tusa ai ma a latou faiga faʻaleagaina, e mafai ona vaevaeina palasitika biodegradable i palasitika photodegradable, palasitika biodegradable, palasitika photobiodegradable ma palasitika faʻamaʻi faʻamaʻi.
Pe a faʻaumatia filifili mole o palasitika photodegradable e ala i auala photochemical, o le palasitika e leiloa lona malosi faaletino ma embrittlements, ona pasi atu lea i le natura.
O le pala o le tuaoi e avea ma efuefu, lea e ulu atu i le palapala ma toe ulu atu i le taamilosaga olaola i lalo o le gaioiga a microorganisms.
E mafai ona vaevaeina palasitika biodegradable i palasitika atoatoa biodegradable ma palasitika biodegradable e tusa ai ma lo latou faiga faʻaleagaina ma le faʻaleagaina.I le taimi nei, o palasitika masoa ma palasitika polyester e sili ona suʻesuʻeina ma faʻaaogaina.
O le palasitika masoa e sili ona manaia ona o ana mea faigaluega faigofie ma le tau maualalo.O palasitika fa'aola fa'aola fa'aola e fa'atatau i palasitika fa'aola e fa'apipi'iina e ala fa'a vaila'au.E mafai ona tu'ufa'atasia e ala i le su'esu'eina o le fausaga e pei o le palasitika fa'alenatura e mafai ona fa'aleagaina po'o palasitika e iai vaega ma'ale'ale fa'aleaogaina.
Palasitika fa'aleagaina fa'aolaola, fa'aigoa fo'i o palasitika malepe, o se faiga tu'ufa'atasi o polymers e mafai ona fa'aleagaina ma palasitika lautele, e pei ole masoa ma polyolefin.E tu'ufa'atasia fa'atasi i se tulaga fa'apitoa, ma o le fa'aleagaina i le si'osi'omaga fa'anatura e le'i mae'a, ma e ono mafua ai le fa'aleagaina lona lua.I polymers biodegradable, o le faʻaopoopoina o photosensitizers e mafai ona faʻaogaina ai le polymers i le photodegradable ma le biodegradable.
Photobiodegradable polymer mea i lalo o nisi tulaga e mafai ona pulea lelei le fua faatatau leaga, e pei o le masoa faaopoopo photodegradable polymer mea PE ina ua uma ona faaleagaina, faia PE porous, vaega faapitoa i luga o le tino ua faateleina, faatasi ai ma le okesene, malamalama, faafesootaʻi vai e matua faateleina, fua faatatau faaleagaina PE. matua faateleina.
Pe a faatusatusa i palasitika photodegradable, o palasitika biodegradable ua avea ma autu vevela i le atinaʻeina o palasitika biodegradable.Ona o palasitika biodegradable e le faigata tele i le siʻosiʻomaga, ma e sili atu ona faigofie le faʻaleagaina atoa o meaola laiti i lalo o tulaga saʻo.O loʻo i ai le lelei o le laʻititi laʻititi, faigofie gaioiga, malosi maualuga ma tau maualalo.O palasitika biodegradable e iai le tele o faʻaoga.I totonu o le Iunaite Setete e masani ona faʻaaogaina i le gaosiga o taga lapisi pala, ato faʻatau;I Europa i Sisifo, o palasitika biodegradable o loʻo faʻaogaina i fagu shampoo, taga lapisi ma taga faʻatau e tasi.O palasitika biodegradable e masani ona faʻaaogaina i vaega nei:
(1) Mea fa'apipi'i
(2) mulch fa'ato'aga
(3) Mea e manaomia i aso taitasi
(4) Mea fa'afoma'i lafoa'i
(5) Ponaivi fai, pa'u fai, fao ponaivi tipi, su'i taotoga
(6) Alava ie
(7) Puleaina o le oneone samasama ma fuafuaga o le taulaga.
Pe a faʻaaogaina palasitika faʻaola i le bioengineering ma mea faʻafomaʻi polymer faʻaleagaina, o latou uiga o le biodegradation e le mafai ona faʻatusatusa i le aʻa photodegradable plastics.O mea mole mole maualalo maualalo e mafai ona ulufale sa'o i le metabolism o meaola, ma maua ai le tele o faʻamoemoega faʻaoga i le aganuʻu a le tino, faʻamalolo faʻamalolo faʻamalosi, ma mea faʻapipiʻi totonu.
