Impact of metal recycling on the reduction of CO2 emissions

CO2 emissions, and Recycling The production of different metals and alloys from primary raw materials generates different amounts of carbon dioxide (CO2) depending on the technology used, energy source and other factors. Below are estimates of CO2 emissions for the production of selected metals: Aluminium: Aluminium production using the electrolytic method (Hall-Héroult method) is very energy intensive and can generate between 9 and 12...
