Ukujonga ngokufutshane kwi-PCR
Okokuqala, yazi ukuba i-PCR "ixabiseke kakhulu." Ngesiqhelo, iplastiki yenkunkuma "PCR" eveliswa emva kokujikeleziswa, ukusetyenziswa, kunye nokusetyenziswa kunokuguqulwa ibe yimathiriyeli ekrwada yemveliso yemizi-mveliso ngokwenziwa ngokutsha ngokwasemzimbeni okanye ukurisayikilishwa kwakhona kweekhemikhali ukuze kuphunyezwe uhlaziyo lwezixhobo kunye nokuphinda kusetyenziswe.
Izinto ezisetyenzisiweyo ezifana ne-PET, i-PE, i-PP, i-HDPE, njl.njl. zivela kwiiplastiki ezilahlwayo eziveliswa ngabantu bemihla ngemihla. Emva kokulungiswa kwakhona, zingasetyenziselwa ukwenza imathiriyeli ekrwada yeplastiki kwizinto ezintsha zokupakisha. Ekubeni i-PCR ivela emva kokusetyenziswa, ukuba i-PCR ayilahlwanga ngokufanelekileyo, iya kuba nefuthe elithe ngqo kwindalo.Ke ngoko, i-PCR okwangoku yenye yeeplastiki ezisetyenziswe ngokutsha ezicetyiswa ziimpawu ezahlukeneyo.
Ngokomthombo weeplastiki ezisetyenzisiweyo, iiplastiki ezisetyenzisiweyo zinokwahlulwa zibeI-PCR kunye ne-PIR. Ukuthetha ngokuthe ngqo, nokuba yi "PCR" okanye iplastiki yePIR, zonke ziiplastiki ezisetyenzisiweyo ezikhankanywe kwisangqa sobuhle. Kodwa ngokubhekiselele kwivolumu yokubuyisela kwakhona, "i-PCR" inenzuzo epheleleyo ngobuninzi; ngokomgangatho wokuhlaziya, iplastiki ye-PIR inenzuzo epheleleyo.
Izizathu zokuthandwa kwePCR
Iplastiki yePCR yenye yezalathiso ezibalulekileyo zokunciphisa ungcoliseko lweplastiki kunye nokunceda "ukungathathi hlangothi kwekhabhoni".
Ngemigudu engapheliyo yezizukulwana ngezizukulwana zoosokhemesti neenjineli, iiplastiki eziveliswe ngepetroleum, amalahle, negesi yendalo ziye zaba zizinto eziyimfuneko kubomi bomntu ngenxa yobunzima bazo, ukuqina, nenkangeleko entle. Nangona kunjalo, ukusetyenziswa kakhulu kweeplastiki kukhokelela ekuveliseni isixa esikhulu senkunkuma yeplastiki. Iiplastiki zePost-consumer recycling (PCR) ibe yenye yeendlela ezibalulekileyo zokunciphisa ukungcoliseka kwendalo yeplastiki kunye nokunceda ishishini lemichiza liqhubele phambili kwi "carbon neutrality". Amasuntswana eplastiki asetyenzisiweyo axutywa nentlaka enyulu ukwenza iintlobo ngeentlobo zeemveliso zeplastiki ezintsha. Ngale ndlela, akugcini nje ukunciphisa ukukhutshwa kwe-carbon dioxide, kodwa ukunciphisa ukusetyenziswa kwamandla
Ukusebenzisa iiPlastiki zePCR: Ukutyhala iNkunkuma yePlastiki iRecycling ngakumbi.
Okukhona iinkampani ezisebenzisa iiplastiki zePCR, kokukhona imfuno iya kuba nkulu, nto leyo eya kwandisa ngakumbi ukurisayikilishwa kweeplastiki ezilahlwayo, kwaye iya kutshintsha ngokuthe ngcembe indlela kunye nokusebenza kweshishini lokuphinda kusetyenziswe iiplastiki ezilahlwayo, nto leyo ethetha ukuba inkunkuma encinci yeplastiki igalelwa, itshiswe kwaye igcinwe ngaphakathi. ubume bendalo.
Ukutyhala umgaqo-nkqubo: Indawo yomgaqo-nkqubo yeeplastiki zePCR iyavulwa.
Thatha iYurophu njengomzekelo, isicwangciso seplastiki se-EU, iiplastiki kunye nerhafu yokupakishaUmthetho wamazwe afana neBritane neJamani. Umzekelo, iRhafu yaseBritani kunye neCustoms ikhuphe "irhafu yokupakisha yeplastiki", kwaye ireyithi yerhafu yokupakisha engaphantsi kwe-30% yeplastiki ehlaziyiweyo yi-200 pounds ngetoni nganye. Indawo yemfuno yeeplastiki zePCR ivulwe ngerhafu kunye nemigaqo-nkqubo.
