But even this old example has made its changes over the years: Today’s recycling technologies in industrials countries are highly so- phisticated, clean processes that have nothing in common with the dirty technologies of the past. Meanwhile, producing steel from scrap means 86% less air pollution. The creation of secondary raw materials via the recy- cling route also expends far less energy than production based on primary raw materials. But primary producers of metals have done their homework too: New metallurgical plants extract metals from ore in a very clean and ef- fective way that minimizes CO2 emis- sions, residuals and energy consump- photo: METALL tion.
