Ukujonga okufutshane kwi-PCR
Okokuqala, yazi ukuba i-PCR "ixabiseke kakhulu." Ngokwesiqhelo, inkunkuma yeplastiki "i-PCR" eveliswa emva kokusasazwa, ukusetyenziswa, kunye nokusetyenziswa inokuguqulwa ibe zizinto ezixabisekileyo kakhulu zokuvelisa imveliso yemizi-mveliso ngokusebenzisa ukuphinda kusetyenziswe okanye ukuphinda kusetyenziswe iikhemikhali ukuze kuphunyezwe ukuhlaziywa kunye nokurisayikilishwa kwezixhobo.
Izinto ezisetyenzisiweyo ezifana ne-PET, i-PE, i-PP, i-HDPE, njl.njl. zivela kwiiplastiki ezilahliweyo eziveliswa kukusetyenziswa kwabantu imihla ngemihla. Emva kokuphinda zisetyenzwe, zingasetyenziselwa ukwenza izinto zeplastiki zokwenza izinto ezintsha zokupakisha. Ekubeni i-PCR ivela emva kokusetyenziswa, ukuba i-PCR ayilahlwanga kakuhle, iya kuba nefuthe elithe ngqo kwindalo esingqongileyo.Ngoko ke, i-PCR okwangoku yenye yeeplastiki eziphinda zisetyenziswe ezicetyiswa ziimpawu ezahlukeneyo.
Ngokwemvelaphi yeplastiki ezisetyenzisiweyo, iiplastiki ezisetyenzisiweyo zinokwahlulwa zibeI-PCR kunye ne-PIR. Ngokuthe ngqo, nokuba yi-"PCR" okanye iplastiki ye-PIR, zonke ziiplastiki ezisetyenzisiweyo ezikhankanyiweyo kuluhlu lobuhle. Kodwa ngokubhekiselele kumthamo wokusetyenziswa kwakhona, i-"PCR" inenzuzo epheleleyo ngobuninzi; ngokubhekiselele kumgangatho wokusetyenziswa kwakhona, iplastiki ye-PIR inenzuzo epheleleyo.
Izizathu zokuthandwa kwe-PCR
Iplastiki yePCR yenye yeendlela ezibalulekileyo zokunciphisa ungcoliseko lweplastiki kunye nokunceda "ukungathathi cala kwekhabhoni".
Ngemizamo engapheliyo yezizukulwana ezininzi zeekhemistri kunye neenjineli, iiplastiki eziveliswe ngepetroleum, amalahle, kunye negesi yendalo ziye zaba zizinto eziyimfuneko ebomini bomntu ngenxa yobunzima bazo obulula, ukuqina, kunye nenkangeleko entle. Nangona kunjalo, ukusetyenziswa kakhulu kweeplastiki kukhokelela ekudalweni kwenkunkuma enkulu yeplastiki. Iiplastiki eziphinda zisetyenziswe emva komthengi (PCR) ziye zaba yenye yeendlela ezibalulekileyo zokunciphisa ungcoliseko lokusingqongileyo lweplastiki kunye nokunceda ishishini leekhemikhali ukuba lihambe liye "kwi-carbon neutral". Amasuntswana eplastiki aphinda asetyenziswe axutywa ne-virgin resin ukwenza iintlobo ngeentlobo zeemveliso zeplastiki ezintsha. Ngale ndlela, ayinciphisi nje kuphela ukukhutshwa kwekhabhoni diokside, kodwa ikwanciphisa nokusetyenziswa kwamandla.
Ukusebenzisa iiPlastiki zePCR: Ukuqhubekeka nokuHlaziya iNkunkuma yePlastiki.
Okukhona iinkampani ezininzi zisebenzisa iiplastiki ze-PCR, kokukhona imfuno inkulu, nto leyo eya kwandisa ngakumbi ukuphinda kusetyenziswe iiplastiki ezilahliweyo, kwaye iya kutshintsha kancinci indlela yokusebenza kunye nokusebenza kweshishini lokuphinda kusetyenziswe iiplastiki ezilahliweyo, nto leyo ethetha ukuba iiplastiki ezilahliweyo ezimbalwa ziyazaliswa, zitshiswe kwaye zigcinwe kwindawo yendalo.
Ukunyanzeliswa komgaqo-nkqubo: Indawo yomgaqo-nkqubo yeeplastiki ze-PCR iyavuleka.
Umzekelo, cinga ngeYurophu, icebo leplastiki le-EU, iplastiki kunye nerhafu yokupakishaimithetho yamazwe afana neBritane neJamani. Umzekelo, iBritish Revenue and Customs ikhuphe "irhafu yokupakisha yeplastiki", kwaye izinga lerhafu yokupakisha elingaphantsi kwe-30% yeplastiki ephinde yasetyenziswa yi-200 yeeponti ngetoni. Indawo yokufunwa kweplastiki ye-PCR ivuliwe ngerhafu kunye nemigaqo-nkqubo.
