Recycling and manufacturing process to produce aluminum does not come without an environmental impact. The aluminum industry accounts for about 1% of greenhouse gas emissions split across two categories. Direct emissions from the aluminum production process account for 40% and the remaining 60% are indirect emissions from electricity generation . The carbon footprint of producing 1 kg of raw aluminum is between 5 to 40 kg of CO2. Therefore, it is important to consider renewable energy processes as aluminum production grows to counterbalance these carbon emissions. An example of ongoing efforts to counterbalance is that most aluminum production facilities are strategically located next to hydro-electric power stations due to the high energy demand .
