Kutshanje, phantsi kwempembelelo yeNkanyamba uLaura, iinkampani zemveliso yePVC eMelika ziye zathintelwa, kwaye imakethi yokuthumela ngaphandle yePVC inyukile. Ngaphambi kwenkanyamba, iOxychem yavala isityalo sayo sePVC ngemveliso yonyaka yeeyunithi ezili-100 ngonyaka. Nangona yaqala kwakhona emva koko, yanciphisa imveliso yayo. Emva kokuhlangabezana neemfuno zangaphakathi, umthamo wokuthumela ngaphandle wePVC uphantsi, nto leyo eyenza ixabiso lokuthumela ngaphandle lePVC linyuke. Ukuza kuthi ga ngoku, xa kuthelekiswa nexabiso eliqhelekileyo ngo-Agasti, ixabiso lemakethi yokuthumela ngaphandle yePVC eMelika linyuke malunga ne-US$150/toni, kwaye ixabiso lasekhaya lihleli.
