Umenzi ochwephesha woomatshini be-thermoforming.
Izixhobo ezilahlwayo, ngokukodwa ezenziwe ngeplastiki kunye nephepha, zibeka imingeni ebalulekileyo yokusingqongileyo. Izitya zeplastiki, ezifumaneka kuyo yonke indawo ekusetyenzisweni kwazo, zinegalelo kwintlekele yehlabathi yongcoliseko lweplastiki. Ubume bazo obungaboliyo buthetha ukuba bayaqhubeka nokusingqongileyo kangangamakhulu eminyaka, bengcolisa iindlela zamanzi, babeka esichengeni izilwanyana zasendle, kwaye babeka izoyikiso kwimpilo yabantu ngokuginya ii-microplastics.
Nangona izitya zephepha zibola, ukuveliswa kwazo kubandakanya ukusetyenziswa kakhulu kobuncwane, kuquka amanzi, amandla kunye nentlaka yeenkuni. Ukutshatyalaliswa kwamahlathi, into eqhelekileyo ekuvelisweni kwephepha, kukhokelela ekulahlekeni kwendawo yokuhlala, ukuchithwa kwezinto eziphilayo, kunye nokukhutshwa kwekhabhoni, okwenza kube nzima ukutshintsha kwemozulu.
Phakathi kweenkxalabo ezikhulayo malunga nempembelelo yokusingqongileyo yezixhobo eziqhelekileyo ezilahlwayo, ezinye izinto ziye zavela njengezisombululo ezinokubakho:
a. Uqalo:
Izitsha ze-bamboo zinika enye indlela ezinzileyo yeplastiki kunye nephepha. I-bamboo sisixhobo esikhula ngokukhawuleza esihlaziyekayo esifuna amanzi amancinci kwaye akukho zinambuzane okanye izichumisi zokulinywa. Ukongeza, izixhobo ze-bamboo zihlala ixesha elide, ziyakwazi ukubola, kwaye zikhaphukhaphu, zizenza zilungele ukusetyenziswa kokusetyenziswa kanye.
b. Ingxowa yeswekile:
Ingxowa yommoba, ifibrous byproduct yemveliso yommoba, inokubunjwa ibe zizitya, iipleyiti nezikhongozeli. Ukusebenzisa i-bagasse njengemathiriyeli ekrwada kunciphisa inkunkuma evela kwimveliso yommoba kwaye kubonelela ngenye indlela enokubola kwizixhobo eziqhelekileyo ezilahlwayo.
c. I-PLA (i-Polylactic Acid):
I-Polylactic Acid (PLA) ithathwe kwisitatshi sesityalo esivundisiweyo (idla ngokuba ngumbona) kwaye imele enye into ehlaziyekayo, enokubola kwiiplastiki ezisekwe kwipetroleum. Ukuveliswa kwe-PLA kuvelisa iigesi ezincinci ze-greenhouse kwaye kufuna amandla amancinci xa kuthelekiswa neeplastiki zendabuko. Nangona kunjalo, ayingomthombo we-PLA oyenza ibe nomtsalane kodwa kunye neendlela zayo zokuphela kobomi; I-PLA inokufakwa kwi-compost kwi-industrial, ihlahlela kwizinto zendalo phantsi kweemeko ezifanelekileyo, inzuzo ebalulekileyo kwiiplastiki eziqhelekileyo.
Ukwenziwa kwezixhobo zePLA kubandakanya ubugcisa obutsha, ngakumbioomatshini be-PLA be-thermoforming kwayeOomatshini bokwenza ikomityi yeplastiki yePLA. I-Thermoforming yinkqubo apho i-PLA sheets ifudunyezwa kwaye ibunjwe kwiimilo ezithile-ezifana neepleyiti, i-cutlery, okanye iikomityi-zisebenzisa i-molds. Ubuchwephesha abuxhasi nje kuphela ukuyilwa koyilo lwemveliso entsonkothileyo neyohlukeneyo kodwa ikwenza oko ngobuchule obuphezulu kunye nokusetyenziswa kwamandla aphantsi. Ezi mpawu zenza izixhobo ze-PLA zisebenze ngokusingqongileyo nakwezoqoqosho.
Xa kuvavanywa izixhobo ezifana ne-polystyrene, i-polyethylene, kunye nephepha elivundisiweyo, i-PLA ihlala ibalasele ngempembelelo yayo ephantsi yokusingqongileyo. Ngokungafaniyo ne-polystyrene kunye ne-polyethylene, i-PLA ayisuki kwimithombo ye-fossil enomda kwaye iqhayisa ngokubola kwe-biodegradability engcono kunezi plastiki. Nangona iphepha le-compostable liyimbangi enamandla, ukuveliswa kweemveliso zephepha kudla ngokubandakanya ukusetyenziswa kwamanzi aphezulu kunye nokusetyenziswa kwamandla, kwaye iimveliso zokugqibela azihlali ixesha elide okanye ziguquguqukayo njengezo zenziwe kwi-PLA.
Amashishini amaninzi atshintshela kwizixhobo zePLA ukomeleza iiprofayili zabo zokuzinza. Kubathengi, ukukhetha izixhobo ezilahlwayo ezisekelwe kwi-PLA kunokuba linyathelo elisebenzayo lokunciphisa impembelelo yokusingqongileyo. Ukwazisa kunye nemfuno evela kubathengi inokuchaphazela kakhulu iminikelo yeemarike, ikhuthaze iinkampani ezininzi ukuba ziqwalasele izenzo ezizinzileyo kwimisebenzi yazo. Ekugqibeleni, ukuziphatha kwabathengi kudlala indima ebalulekileyo ekukhuthazeni ukugcinwa kokusingqongileyo:
a. Imfundo kunye noKwazisa:
Ukuphakamisa ulwazi malunga neempembelelo zokusingqongileyo zezixhobo ezilahlwayo kunye neenzuzo zokukhetha ezinye iindlela ezizinzileyo. Ukufundisa abathengi malunga neendlela ezifanelekileyo zokulahla kunye nokubaluleka kokunciphisa iiplastiki ezisetyenziselwa enye kunokuqhuba utshintsho lokuziphatha.
b. Ukutshintsha indlela yokuziphatha:
Ukukhuthaza abathengi ukuba bakhethe izixhobo ezinokusetyenziswa kwakhona xa kunokwenzeka kwaye bakhethe izinto ezinokulahlwa ezinobungani nokusingqongileyo xa kuyimfuneko. Ngokwenza ukhetho olufanelekileyo kwindawo yokuthenga, abathengi banokunciphisa indawo yabo yokusingqongileyo kwaye bafake isandla kutshintsho olulungileyo.
c. Umgaqo-nkqubo noMgaqo:
Ukuphumeza imigaqo-nkqubo ekhuthaza ukusetyenziswa kwezinto ezizinzileyo kunye nokukhuthaza uphuhliso lweziseko ezingundoqo ukuze zilahlwe ngokufanelekileyo kunye nokurisayikilisha. Imimiselo kaRhulumente, imigangatho yoshishino, kunye namanyathelo oshishino anokuqhuba ukusungula izinto ezintsha kunye nokuphendula kwimveliso kunye nokusetyenziswa kwezixhobo ezilahlwayo.
Ukukhetha imathiriyeli efanelekileyo yezixhobo ezilahlwayo sisigqibo esinamacala amaninzi esifuna ukuqwalaselwa kweempembelelo zokusingqongileyo, ukusetyenziswa kobutyebi, kunye nenkqubela phambili yobuchwepheshe. I-PLA ivela njengokhetho oluphambili ngenxa yemvelaphi yayo ehlaziyiweyo, i-biodegradability, kunye ne-carbon footprint ephantsi. Njengoko iteknoloji ihambela phambili kunye nokuqonda kwabathengi kukhula, ukwamkelwa kwezixhobo ze-PLA kunokudlala indima ebalulekileyo ekudambiseni imiba yokusingqongileyo ehambelana neeplastiki ezilahlwayo. Ukuqhubela phambili, kubalulekile ukuba i-innovation iqhubeke nokucokisa kunye nokwandisa izicelo ze-PLA, ukuqinisekisa ukuba ukuzinza akuphazamisi ukusebenza okanye ukufikeleleka.
