Muaj ntau tus neeg tham txog ib puag ncig tus phooj ywg lub hnab khib nyiab.Cov neeg sib txawv muaj cov kev cai sib txawv rau ib puag ncig tus phooj ywg lub hnab khib nyiab: qee tus ntseeg tias ntev npaum li cov khoom siv raw zoo siv los tsim cov hnab khib nyiab, nws yog ib puag ncig tus phooj ywg, thiab qee tus ntseeg tias kev ntxiv cov khoom zoo rau cov hnab khib nyiab yog ib puag ncig zoo.Yog lawm, thiab qee tus neeg xav tias ntev npaum li lawv pom daim ntawv qhia txog kev xeem, cov hnab khib nyiab yog ib puag ncig zoo.Niaj hnub no, Science thiab Technology yuav sib tham txog dab tsi lub hnab khib nyiab yog ib puag ncig tus phooj ywg tiag tiag.
"Environmentally friendly" hnab yas hauv khw feem ntau suav nrog cov hom no: cov hnab yas degradable, hnab yas biodegradable, thiab hnab yas compostable.
Lub hnab yas degradable: Cov polymer hauv lub hnab yas yog ib feem lossis tag nrho puas vim yog ultraviolet hluav taws xob, oxidation corrosion, thiab lom corrosion.Qhov no txhais tau hais tias kev hloov ntawm cov khoom xws li fading, nto tawg thiab fragmentation.
Biodegradable hnab yas: Cov txheej txheem biochemical uas cov organic teeb meem hauv cov hnab yas yog tag nrho lossis ib nrab hloov mus rau hauv dej thiab carbon dioxide, lub zog thiab cov biomass tshiab nyob rau hauv kev ua ntawm cov kab mob (cov kab mob thiab cov fungi).
Compostable hnab yas: hnab yas tuaj yeem biodegraded nyob rau hauv tshwj xeeb tej yam kev mob ntawm high-temperature av, thiab feem ntau yuav tsum muaj composting kom ua tau zoo degradation efficiency.
Tsuas yog lub hnab khib nyiab tag nrho yog cov hnab khib nyiab tiag tiag.Lawv yog tsim los ntawm cov ntaub ntawv carbon uas muab rho tawm los ntawm cov nroj tsuag xws li pob kws thiab qab zib.Lawv tuaj yeem degraded rau hauv dej thiab carbon dioxide yam tsis muaj pa phem rau huab cua thiab av.Txij li thaum photodegradation thiab dej degradation yuav tsum tau degraded nyob rau hauv ib qho chaw tshwj xeeb, hnab yas hauv khw feem ntau yog "biodegradable."
Tam sim no, tus nqi ntawm cov hnab khib nyiab degradable yog 3-5 npaug ntawm cov hnab khib nyiab zoo tib yam, thiab tus nqi siv ntau dua li cov hnab khib nyiab zoo tib yam.Kev sib koom ua lag luam tseem nyob rau theem me me thiab tsis muaj kev ncig ntau.Peb tuaj yeem xaiv yuav Nyeem cov lus qhia ua tib zoo thiab xaiv yog tias koj muaj lub hom phiaj.
