Itafile yebhayoloji elahlayo iya kuba yimeko kwixesha elizayo

Ngo-1986, i-foam tableware yaqala ukusetyenziswa koololiwe baseTshayina. Ekuqaleni kwenkulungwane yama-21, iibhokisi zesidlo sasemini ezinogwebu ziye zaba zezona zinto ziqhelekileyo ezilahlwayo. Kukho iingxaki ezinzulu ngokuveliswa, ukusetyenziswa kunye nokuphinda kusetyenziswe i-tableware ye-foam elahlayo. Amanye amagwebu asetyenziswa kwinkqubo yokuvelisa aya kutshabalalisa i-ozone ye-atmospheric, kwaye ezinye zineengozi ezifihlakeleyo ezifihlakeleyo; ukusetyenziswa okungafanelekanga kumaqondo obushushu aphezulu kunokuvelisa ngokulula izinto eziyingozi kwimpilo yabantu; ukulahla ngokungenankathalo emva kokusetyenziswa kunokubangela ungcoliseko olukhulu lokusingqongileyo; ukungcwatywa emhlabeni kunokubangela ungcoliseko olukhulu lokusingqongileyo. Kunzima ukwehlisa umgangatho, kuya kubangela ungcoliseko kumhlaba namanzi aphantsi komhlaba, kwaye kunzima ukurisayikilishwa. Itafile yogwebu elahlayo yathintelwa kamva.

Malunga no-2003, abanye abavelisi basekhaya baqalisa ukuphehlelela i-PP isitofu esibunjiweyo setafile yezinto ezilahlwayo. Uninzi lwabo lusebenzisa iimolds zoomatshini abavela kumazwe angaphandle. Kwiintsuku zangaphambili, i-export yayiyeyona nto iphambili kwimarike. Ngophuhliso lwe-Intanethi kunye nokunyuka kwamaqonga okuthatha, iibhokisi zesidlo sasemini zePP ziye zayiveza ngokuthe ngcembe imida yazo. Zisenokuphuphuma kwaye zingagqunywanga ngexesha lokuhamba. Ukulahlwa ngokungacwangciswanga kweebhokisi zesidlo sasemini zePP nako kunokubangela ungcoliseko olumandla lokusingqongileyo; kunzima ukuthoba isidima xa ungcwatywe emhlabeni. Phantsi komgaqo-nkqubo "wokuvalwa kweplastiki / uthintelo", ezo bhokisi zesidlo sasemini nazo zifuna impumelelo kunye nokuphuhlisa kwicala lokhuseleko lokusingqongileyo.

Uphuhliso lwelizwe lam loshishino lokubumba i-pulp lwaqala ngo-1980 kwaye lwahlala de kwango-2000. Ngo-2001, ilizwe lam langena ngempumelelo kwiWorld Trade Organisation. Amashishini okubumba ipulp yasekhaya aphuhliswe ngokukhawuleza, kwaye inkqubo yemveliso, itekhnoloji kunye nezixhobo zathatha inkangeleko entsha. Iindidi ezahlukeneyo zeemveliso ezibunjiweyo zepulp ziyavela. Ukusukela ngo-2020, umgaqo-nkqubo welizwe lam "wokuvalwa kweplastiki / uthintelo" uye waphunyezwa ngokuthe ngcembe, kwaye ishishini lokubumba i-pulp likwinqanaba lophuhliso olukhawulezayo ukusukela ngo-2020.

Izinto ezikrwada zeemveliso ezibunjiweyo ze-pulp zivela kuluhlu olubanzi lwemithombo, kwaye uninzi lwezona zinto ziphambili zilutyalo lwezityalo, njengeengcongolo, umququ wengqolowa, umququ werayisi, i-bagasse, i-bamboo, njl. sebenzisa ingcongolo, i-bagasse, bamboo, umququ wengqolowa kunye nezinye iintsinga zengca njengoko ezona zixhobo ziphambili zineenkqubo zazo zokulawula ungcoliseko. Ngokubhekiselele kwimathiriyeli ekrwada, iimveliso ezibunjiweyo zephepha ziqalise ngokupheleleyo kwimodeli yendlela "ye-pulping esembindini kunye nemveliso ye-decentralized", ayigcini nje ngokuba neengxaki zongcoliseko lokusingqongileyo, kodwa inokufumana iziqinisekiso ezithembekileyo zezinto ezikrwada. Phakathi kwabo, i-bamboo yeyona nto ingcono kakhulu. I-bamboo ikhula ngokukhawuleza, ayinazintsalela zezitshabalalisi nezichumisi, kwaye inevumba elimnandi lendalo. I-bamboo sisixhobo esihlaziyekayo, esivundisiweyo esineendlela ezahlukeneyo zokusebenzisa ekupakheni.

Itekhnoloji yemveliso yeemveliso ezibunjiweyo ze-pulp zilula, kwaye akukho mithombo yongcoliseko ngexesha lenkqubo yokuvelisa, ehlangabezana neemfuno zemveliso ehambelana nokusingqongileyo. Ukongeza, izixhobo zokuvelisa i-pulp ziveliswa kakhulu ngaphakathi, nto leyo inceda kakhulu ekukhuthazeni nasekusetyenzisweni kweprojekthi.

Iimveliso ezibunjiweyo zePulp zinoluhlu olubanzi lwezicelo, umthamo wentengiso enkulu, kunye namandla atyebileyo okucofa. Iimveliso zabo zinokusetyenziswa ngokubanzi ukupakishwa kwezixhobo zombane, ukutyala kunye nokulima izithole, izixhobo zonyango, izixhobo zokutya, kunye neelitha zemveliso eziethe-ethe. I-pulp ehambelanayo Umgca wokuvelisa ukubumba unokuvelisa iimveliso ezahlukeneyo kunye nokusetyenziswa okuhlukeneyo ngokuphucula nje kunye nokutshintsha i-molds. Imisebenzi yayo eyahlukeneyo kunye nokuphinda isetyenziswe kwenza ezinye iimveliso ezifanayo zingahambelani.

I-Pulp molded tableware lisebe elibalulekileyo lemveliso ezibunjiweyo zepulp. Kulula ukuyihlaziya, ingaphinda isetyenziswe, kwaye iyonakaliseka. Isuka kwindalo kwaye ibuyela kwindalo. Yimveliso eqhelekileyo engangcolisekiyo, eyonakeleyo, eluhlaza kunye nokusingqongileyo, ehambelana kakhulu nexesha lanamhlanje. Imfuneko yokusebenzisa iimveliso ezibunjiweyo ze-pulp ayincedi nje kuphela ukusindisa okusingqongileyo kunye nokunciphisa utshintsho lwemozulu, kodwa yandisa ubomi bomntu.

Njengoko ulwazi lwabantu malunga nokhuseleko lokusingqongileyo kunye nempilo luqhubeka luqina, i-tableware ehambelana nokusingqongileyo ngokuqinisekileyo iya kukwazi ukutshintsha i-tableware yeplastiki elahlayo kwixesha elizayo.
