Ifakwe imojuli yokulawula ethuthukiswe ngokuzimela yokuhlela umzila ozenzakalelayo, irobhothi elihlakaniphile lokuqapha lingakwazi ukuzulazula liye ezindaweni ezikhethiwe ngezikhathi ezithile futhi lifunde okurekhodiwe kumathuluzi nasezindaweni ezikhethiwe. Inika amandla ukuhlola nokuhlola okuhlakaniphile kwamarobhothi kanye nokuqapha okukude okungenamuntu ukuze kusize ukuthathwa kwezinqumo ezigcawini zezimboni ezifana namandla kagesi, i-petroleum ne-petrochemical, indaba yamanzi, nepaki.
