Ngokubuyekeza izimiso nezinqubo ezihamba phambili ezivezwe kulo mhlahlandlela, amaqembu onjiniyela angakwazi ukwenza indlela yokuhlola esebenza kahle eboshelwe izidingo zabo zohlelo lokusebenza lwe-PCB kanye nemikhawulo. Lokhu kuzohamba ibanga elide ekuqinisekiseni ukwaneliseka kwamakhasimende ngokuvimbela amabhodi anamaphutha ukuthi afinyelele emikhiqizweni yokugcina.
