Iivalvu zeplastikizisetyenziswa kwiindawo ezininzi kuphuhliso lwemizi-mveliso yelizwe lam, kwaye iimveliso zeplastiki kwishishini lokukhusela iikhemikhali kunye nokusingqongileyo zixatyiswa kakhulu. Kucacisiwe ngokucacileyo ukuba isantya sophuhliso kufuneka sikhawuleziswe, kwaye sitsale ingqalelo enkulu kumasebe kazwelonke, sifuna iiplastiki zobunjineli zelizwe lam ukuba zikhawulezise uphuhliso. Ke ngoko, iingcali zeShishini ziqikelela ukuba ishishini leplastiki lelizwe lam liya kujongana nophuhliso kuzo zonke iinkalo, ingakumbi kuphuhliso lweemveliso zeplastiki zobunjineli. Ukuphucula amandla okuvelisa izinto ezintsha azimeleyo kwishishini lokucubungula iiplastiki, ukuthandwa kwezinto ezintsha, ubuchwepheshe obutsha, izixhobo ezintsha kunye neemveliso ezintsha kuye kwaba yinto ephambili.

Iivalvu zebhola zeplastiki,iivalvu zebhabhathanekwayeiivalvu zokujongazizinto ezibalulekileyo kusapho lweevalvu, kuba ezi valve zenziwe ngeplastiki yobunjineli, ngoko ke zombini ngokwendlela esebenza ngayo kunye nokusebenza kwayo, zinezibonelelo ezithile. Izinga lokusetyenziswa kweevalvu zeplastiki kwilizwe lam Ngokukhula konyaka nonyaka, iinkampani ezininzi ziqalile ukuthenga iivalvu zeplastiki, kwaye ezinye iinkampani zeevalvu zangaphandle zihlasela imakethi enkulu yelizwe lam, zibonisa umkhwa wokuchuma kuyo yonke indawo kweli lizwe.

Iivalvu zebhola zeplastiki, iivalvu zebhabhathane kunye neevalvu zokujonga zibaluleke kakhulu kwezinye iiprojekthi zokukhusela iikhemikhali kunye nokusingqongileyo. Ngenxa yokusebenza okuphezulu kweevalvu zeplastiki, zinokuhlangabezana neemfuno zeprojekthi ngcono kunezinye iivalvu zentsimbi engagqwaliyo, kuba iivalvu zeplastiki zilula ngobunzima, kulula ukuzifaka, kwaye zingabizi kakhulu. Zifikeleleka lula kwaye zinokuphepha ngempumelelo ingxaki yokuvuza, kwaye umthamo wevalvu yeplastiki uncinci, indawo yomgangatho nayo incinci, ilula kakhulu ekuthuthweni nasekufakweni, kwaye ukuqhaqha kunye nokugcinwa kulula. Ke ngoko, amathuba okusebenzisa iivalvu zeplastiki kubunjineli Amathuba aya ekhula kwaye ekhula kwaye enethemba ngakumbi.

Namhlanje, ilizwe lam libe ngumvelisi omkhulu, umthengi kunye nomthengisi weemveliso zeplastiki kwihlabathi liphela. Abanye abahlalutyi bathi njengoko itekhnoloji yokutshintsha amalahle ukuya kwi-olefin ikhula kwaye isetyenziswa kakhulu, iimveliso zeplastiki ziya zithatha indawo yentsimbi kancinci kancinci, iglasi, imibhobho yeekhemikhali, iivalvu kunye neminye imboni iyamkelwa, iplastiki esekwe kwi-bio kunye nezinye iiplastiki ezibolayo kwaye ezinye izinto ezintsha ziqala ukusetyenziswa.

Kwixesha elizayo, uphuhliso lweshishini leplastiki luya kuxhomekeka kumandla eshishini ngokwalo kwelinye icala, kwaye kwelinye icala luya kuxhomekeka kumandla amashishini aqokelelwe ndawonye. Lonke ishishini leekhemikhali zokukhusela okusingqongileyo liya kuba ngamandla aqhuba uphuhliso lweshishini leplastiki. Abavelisi kufuneka baphucule amandla abo obuchwephesha kwaye baphucule rhoqo umgangatho weemveliso zabo ngelixa benciphisa iindleko, ukuze uphawu lwabo lweevalvu zeplastiki lukhokele indlela kwindawo yamaza amakhulu nesanti.
