Cov khoom yas twb nyob txhua qhov chaw hauv peb lub neej. Yav dhau los, yas yog cov khoom siv hloov pauv, pheej yig, ruaj thiab ntau yam. Nws yog cov khoom zoo uas ua rau cov yas yog ib qho khoom siv nrov tshaj plaws hauv ntiaj teb. Txawm hais tias tus nqi ntawm kev tsim cov yas yog tsawg, tus nqi ib puag ncig yog loj heev. Lub degradation ntawm cov pa phem yas yuav siv sij hawm ntau tshaj plaub puas xyoo, yog li feem ntau ntawm cov plastics ua tseem muaj nyob rau hauv qee hom.
Hmoov tsis zoo, cov pa phem feem ntau tshwm sim hauv peb cov dej hiav txwv, ua rau cov tsiaj qus puas tsuaj. Nyob rau hauv lub ntiaj teb no, yog tias tib theem ntawm cov pa phem nyob rau hauv lub ntiaj teb no Economic Forum qhia tau hais tias: Nyob rau hauv 2050, yuav muaj cov yas nyob rau hauv dej hiav txwv ntau dua ntses. Raws li qhov tseeb no, nws yog ib qho tsim nyog yuav tsum tau qhia cov yas thiab nqis peev rau lwm cov khoom lag luam kom txo peb cov khoom siv yas thiab pov tseg.
Txawm hais tias qhov laj thawj rau tib neeg los txhawb cov yas yog nws cov khoom siv rov ua dua tshiab. Txawm li cas los xij, cov txheej txheem tsis tau npaj thiab cov neeg paub txog pej xeem tsim cov khoom pov tseg ntau dua li cov khoom siv rov ua dua tshiab. Ob qho no ua rau muaj txiaj ntsig zoo rau cov nqi ntawm cov yas. Scientific Advances luam tawm ib txoj kev tshawb fawb los ntawm cov kws tshawb fawb ntawm University of Georgia thiab University of California. Lub hom phiaj ntawm kev tshawb fawb yog nyob rau hauv kev tsim, siv thiab txoj hmoo ntawm tag nrho cov yas hauv keeb kwm. Cov kws tshawb nrhiav pom tias nyob nruab nrab ntawm xyoo 1950 thiab 2015, kwv yees li 12% ntawm cov yas tau raug hlawv, 9% ntawm cov yas tau rov ua dua tshiab, thiab 79% ntawm tag nrho cov yas tsim hauv keeb kwm raug muab pov tseg thiab muab tso rau hauv qhov chaw pov tseg lossis xwm txheej. Nquag rau hauv ib puag ncig. Hauv lwm lo lus, 4,900 metric tons ntawm cov yas tsis tau siv dua, thiab cov yas no tam sim no nyob rau hauv qhov chaw pov tseg thiab ib puag ncig ntuj thiab yuav khaws cia rau ntau pua xyoo.
Nyob rau tib lub sij hawm, qhov tshwm sim ntawm pulp molding tau hloov pauv peb, thiab nws qhov tshwm sim tau dhau los ua kev hloov pauv zoo dua rau cov yas. Ntawm CSL, peb tsim thiab tsim cov ntim khoom zoo ib puag ncig ua los ntawm cov khoom siv rov ua dua tshiab -kev lag luam duab los qhia thiab ntawv. Txawm tias cov khoom seem tuaj yeem xa rov qab mus rau qhov sib xyaw ntawm cov pulp, yog li tsis muaj cov khoom siv pov tseg thaum lub sijhawm tsim khoom. Moulded pulp ntim yog ib qho yooj yim rau rov siv cov duab los qhia thiab ntawv, thiab nws kuj yog biodegradable. Yog li ntawd, yog tias nws tsis nkag mus rau hauv cov khoom siv rov ua dua tshiab rau qee qhov laj thawj, thov so kom paub tseeb tias nws yuav tsis ua phem rau peb cov dej hiav txwv rau ntau tiam neeg.
Niaj hnub no, raws li kev paub txog kev tiv thaiv ib puag ncig thiab kev qhia txog ntau txoj cai txwv tsis pub siv cov khoom siv yas, cov khoom ntawm molded pulp ntim tau them nyiaj ntau dua thiab ntau dua rau cov neeg. Txawm hais tias lub ntim ntim tsis tuaj yeem daws tau tag nrho cov kev xav tau ntim, nws yog ib qho kev xaiv zoo uas tuaj yeem pab peb txo qhov teeb meem ntawm cov pa phem hauv ntiaj teb.
