O le a le pusa meaai e mafai ona pala?
Biodegradable lunch box o se pusa o le aoauli e mafai ona faʻaleagaina e microorganisms (bacteria, mold, algae) i le siosiomaga faʻanatura i lalo o le gaioiga o enzymes, biochemical reactions, mafua ai suiga i le foliga mai o le limu i le uiga i totonu, ma mulimuli ane faʻavaeina carbon dioxide ma vai.O le faʻaleagaina atoa o le faʻagasologa e mafai ona faʻaleagaina i ni mea e le afaina e aunoa ma se faʻaogaina faʻapitoa, o se faiga umi tele.Pusa mea'ai fa'aola fa'ama'i fa'amae'aina otaota fa'aopoopo i le GB18006.3-2020 "mana'oga fa'apitoa fa'apitoa o mea'ai fa'ato'aga fa'aleagaina" fa'aleagaina le fa'atinoga, e tatau fo'i ona iai le tau toe fa'aaogaina, faigofie ona toe fa'aoga, po'o le faigofie i le fa'amama otaota ma le vevela vevela togafitiga.
Lona lua, o a vaega autu o pusa mea'ai e mafai ona fa'aumatia?
O pusa o le aoauli biodegradable e faia i ituaiga e lua o mea: o le tasi e faia i mea faʻanatura, e pei o pepa oloa, vaomago, starch, ma isi mea, e mafai ona faʻaleagaina, e taʻua foi o oloa faʻaleleia le siosiomaga;o le isi e faia i le palasitika e fai ma vaega autu, faʻaopoopoina masoa, photosensitizers ma isi mea.
1、Biodegradable mea masani pusa meaai
O pusa mea'ai fa'alenatura e mafai ona fa'aleagaina e fa'aigoaina fo'i o pusa mea'ai e mafai ona pala.Biodegradable lunch box ose oloa tau puipuiga o le siosiomaga.E faia i le masoa e avea ma mea mataʻina autu, faʻaopoopoina le tausaga faʻaletausaga o le tuputupu aʻe o le fiber fiber powder ma faʻaopoopoga faʻapitoa, ma faʻapipiʻiina e ala i vailaʻau ma auala faʻaletino e fai ai pusa meaʻai vave biodegradable.Talu ai o le masoa ose polymer fa'alenatura e mafai ona pala, e pala i le kulukose ma mulimuli ane vai ma le carbon dioxide i lalo o le gaioiga a microorganisms.E le gata i lea, o le mea e faʻafefiloi faʻatasi ai o se mea faʻaleagaina atoa, o lea e mafai ai ona fai atu e leai se aʻafiaga i le siosiomaga.O le puna autu o le masoa, o mea mata mo le gaosiga, e mafai ona avea ma laau i tausaga taʻitasi e pei o sana, pateta, pateta suamalie ma manioka.E masani lava, o pusa o le aoauli e mafai ona faʻaleagaina e le atoatoa, mo se faʻataʻitaʻiga, o le tele o mea e gaosia o meaʻai o meaʻai, ma o loʻo iai faʻafitauli e pei o le puipuia o le limu e leʻi foia.
2、Biodegradable pusa meaai palasitika
O le gaosiga o mea mataʻutia o ia pusa meaʻai faʻaaogaina o le palasitika biodegradable, o le mea e taʻua o le palasitika biodegradable o le faʻaopoopoina lea o se aofaʻi o mea faʻaopoopo, e pei o photosensitizers, starch ma isi mea mata i le gaosiga o le palasitika.I lenei auala, e mafai ona fa'apalapala oloa palasitika biodegradable i ni vaega mai o latou foliga atoa pe a uma ona faʻaaogaina ma lafoai i le natura mo le tolu masina o faʻaaliga, ma faʻaleleia atili ai le siosiomaga, a itiiti ifo i le vaʻaia.Ae ui i lea, o le pito sili ona leaga o lenei tekinolosi o nei vaega e le mafai ona faʻaauau ona faʻaleagaina, ae naʻo le liliu mai fasi pepa lapopoa i ni fasi palasitika laiti, lea e le mafai ona faʻatinoina le galuega o le faʻaumatiaina o le paʻepaʻe paʻepaʻe.
