Waagii hore, walaxda dacarta leh ee PFAS ayaa ku dahaadhay dusha sare ee qaar ka mid ahbaakadaha cuntada wuxuu lahaa kansar gaar ah, sidaas darteed warshado badan oo baakadaha cuntada degdega ah ee warqadda ayaa u jeestay inay ku dahaadhaan dusha sare ee warqadda lakabka PE, PP, EVA, sarin iyo bacaha kale ee balaastigga ah si ay u gaadhaan ujeedada biyuhu iyo ilaalinta saliidda, iyo in laga fogaado waxyeelada ay walxaha suufku ku shubeen caafimaadka dadka. Si kastaba ha noqotee, deegaanka dabiiciga ah, sida PFAS, qaab dhismeedka molecular ee aflaanta balaastikada ah waa mid xasiloon oo aan la dumin karin, sidaas darteed waxay keenaysaa wasakh caag cad.
Sidaa darteed, shirkadaha qaarkood waxay soo saareen (anaerobic + marine) tignoolajiyada biodegradation ee alaabta polymerka (sida balaastikada, caagga, fiilooyinka kiimikaad), kuwaas oo gaadhi kara wasakhaynta bayoofalka, xaalufka badda, iyo nabaad-guurka compost.
(Anaerobic + badda) Tiknoolajiyada biodegradation waa qiimaha ugu hooseeya, qaddarka dheeriga ah waa 1%, qiimaha kaliya ayaa kordhay 20% -30%, iyo agabka wax soo saarka ee asalka ah, qalabka wax soo saarka, hababka, iyo sifooyinka guud ee alaabtu maaha u baahan in wax laga beddelo. Taas bedelkeeda, qiimaha teknoolajiyada si buuxda loo nadiifin karo sida PLA, PBAT, PBS, iyo PHA waxay kordhin doonaan ugu yaraan 1-2 jeer, iyo waxqabadka guud ee alaabta la dhammeeyey ma gaari karto waxqabadka balaastikada dhaqameed. Habka wax soo saarka, alaabta ceeriin, qalabka wax soo saarka , habka wax soo saarka, iwm waxay u baahan yihiin in si weyn loo beddelo oo la hagaajiyo.
Anaerobicnoolayn karo Masterbatch waa masterbatch organic kaas oo soo bandhigi kara balaastikada marxaladda xaalufka microbial iyada oo loo marayo waxqabadyada kiimikada ee ay keento bakteeriyada (inta badan bakteeriyada anaerobic), oo ka tagaysa kaliya carbon dioxide, methane iyo humus, kuwaas oo methane loo isticmaalo tamar nadiif ah oo dib loo warshadeyn karo, humus ayaa loo isticmaali karaa sida bacriminta Ka dib marka lagu daro balaastikada anaerobic biodegradable masterbatch, waxaa lagu baabi'in karaa qashinka qashinka iyada oo loo marayo falcelinta anaerobic, iyo sidoo kale waxay hoos u dhigi kartaa biyaha badda.
Nabaad-guurka anaerobic microbial wuxuu dhacaa mar walba dabeecadda, iyo sababta oo ah geeddi-socodku aad ayuu u gaabiyaa, ma fududa in la ogaado. Si kastaba ha ahaatee, ku darida anaerobic biodegradable masterbatch waxay si weyn u dedejin kartaa habka xaalufka caagadaha dabiiciga ah ee adag. Anaerobic biodegradable masterbatch waxay u ogolaataa balaastiig inay dhamaystirto afarta marxaladood ee xaalufka heer sare.
Tilmaamaha iyo faa'iidooyinka muuqda ee (anaerobic + badda) tignoolajiyada biodegradation eewarqad dahaarka leh:
1. Nadiifi oo badbaado leh. Tiknoolajiyadan waxaa loo isticmaali karaa ilaha kaarboon ee microorganisms anaerobic ee jawi anaerobic ah, ka dib ficil enzymatic ah, ilaa isha kaarboonka adag ee dabiiciga ah la dheefshiido, waxay si buuxda u buuxisaa shuruudaha alaabta cagaaran ee kala-saarista qashinka.
2. Looma baahna in la beddelo qalabka wax soo saarka, looma baahna in la maalgeliyo qalab kasta oo cusub oo wax soo saar ah.
3. Ma saameynayso waxqabadka alaabta asalka ah mana kordhinayso kharashka aad u badan.
4. Kuma xaddidna cimriga alaabta iyo muddada kaydinta.
5. Dib loo warshadayn karo.
