Tala Fou ma Tusitala

I tausaga talu ai nei, o nisi o taunuʻuga na faia i mea lanu meamata mea faʻapipiʻi fanua, lea na faʻalauiloaina ma faʻaogaina i maketi i totonu o le atunuʻu ma le lalolagi atoa. O mea lanu meamata ma mea e teu ai le siosiomaga e faasino i na mea e ogatusa ma le Life Cycle Assessment (LCA) i le faagasologa o le gaosiga, faʻaaogaina ma toe faʻaaogaina, lea e faigofie mo tagata e faʻaoga ma e le afaina tele ai le siosiomaga, ma e mafai ona faʻaleagaina. pe toe fa'aaogaina e i latou lava pe a uma ona fa'aoga.

I le taimi nei, e tele lava ina matou fautua atu mea e faʻafeiloaʻi ai le siʻosiʻomaga e vaevaeina i ituaiga e 4: mea pepa pepa, mea faʻale-natura, mea faʻaleagaina, meaʻai.

1. PepaMeafaitino

O mea pepa e sau mai punaoa faanatura laupapa. Ona o le lelei o le faʻaleagaina vave, faigofie toe faʻaaogaina ma le lautele o faʻaoga, o mea pepa ua avea ma mea faʻapipiʻi lanu meamata masani ma le lautele o le faʻaogaina ma le taimi muamua e faʻaaoga ai.

Ae ui i lea, o le faʻaaogaina tele e faʻaumatia ai le tele o fafie. O le pulupulu e le o ni fafie e tatau ona faʻaaoga malosi e fai ai pepa, e pei o vao, vaomago, bagasse, maʻa ma isi, nai lo fafie, lea o le a mafua ai le faʻaleagaina o le siosiomaga.

A maeʻa le faʻaaogaina oafifiina pepa, o le a le faʻaleagaina ai le faʻaleagaina o le siʻosiʻomaga, ma e mafai ona faʻaleagaina i meaʻai. O le mea lea, i le tauvaga mataʻutia o aso nei o mea faʻapipiʻi, o loʻo i ai pea se nofoaga o afifi pepa, ma ona tulaga faʻapitoa.

2. Mea faanatura faanatura

O mea faʻapipiʻi faʻaanatura faʻaanatura e masani ona aofia ai mea faʻapipiʻi laau ma mea faʻamalo, o mea o loʻo i ai e sili atu i le 80%, faʻatasi ai ma le lelei o le leai o se faʻaleagaina, faʻafouina, faigofie gaioiga faʻapea foʻi ma foliga matagofie ma aoga. A maeʻa ona faʻaaogaina, e mafai ona liua meaʻai ua lafoai ma iloa ai le taamilosaga o le siʻosiʻomaga.

O nisi o la'au o ni mea fa'apipi'i fa'anatura, pe a fai o sina fa'agaioiga e mafai ona avea ma tofo fa'anatura o afifiina, e pei o lau, ofe, ipu, bamboo, ma isi.afifimaua foliga matagofie ma tofo faaleaganuu, lea e mafai ona toe lagona ai tagata i le natura ma maua le lagona o le siʻosiʻomaga muamua.

3. Mea fa'aleagaina

O mea faʻaleagaina e masani lava ona faʻavae i luga o palasitika, faʻaopoopoina photosensitizer, fetuutuunai fetuutuunai, biological degradation agent ma isi mea mata, e faʻaitiitia ai le mautu o palasitika masani, faʻavaveina lona saoasaoa faʻaleagaina i le siosiomaga masani e faʻaitiitia ai le filogia i le siosiomaga masani. E tusa ai ma auala faʻaleagaina eseese, e mafai ona vaevaeina i mea e mafai ona faʻaogaina, mea faʻapipiʻi ata, mea faʻaleagaina faʻamaʻaina ma mea faʻaleagaina masini.

I le taimi nei, o mea masani faʻaleagaina masani e masani ona faʻaaogaina, e pei o le masoa, polylactic acid, ata PVA; O isi mea fou fa'aleagaina, e pei o le cellulose, chitosan, polotini ma isi mea fa'aleagaina e iai fo'i le tele o le atina'e.

4. Mea taumafa

O mea taumafa o mea masani ia e mafai ona 'ai sa'o pe 'ai e le tino o le tagata. E pei o le: lipid, fiber, starch, polotini, ma isi malosiaga fa'afouina. Faatasi ai ma le alualu i luma o le faasaienisi ma tekinolosi, o nei mea e faateleina le matua ma faasolosolo malie i tausaga talu ai nei, ae ona o latou meaʻai-grade meamata, ma tulaga mama tumama e manaʻomia i le gaosiga o le gaosiga e mafua ai le maualuga o tau.

Mo le fa'apipi'iina o le puipuiga o le si'osi'omaga maualalo, le atina'eina o le lanu meamata fouafifiinamea e tatau ona taua, i le taimi lava e tasi e tatau ona faatino le mamanu afifiina. O mea faʻapipiʻi puipuia o le siosiomaga i le faʻapipiʻiina o mamanu o le a avea ma se tasi o faʻaoga masani i le lumanaʻi.

E ala i le faʻaleleia atili o le fausaga fausaga, mamanu mama, faʻateleina le toe faʻaaogaina ma le faʻaaogaina o meafaitino, o le a tatou ausia le aʻafiaga o le tele-faamoemoega, ina ia faʻaitiitia ai le faʻaogaina o punaoa faanatura.
