28 7. Energy: Global Stock and Savings Due to Recycling Aluminium recycling benefits present and future generations by conserving energy and other natural resources. It saves up to 95% of the energy required for primary aluminium production, thereby avoiding corresponding emissions, including greenhouse gases. 38 million tonnes of primary aluminium and 38 million of remelted aluminium were produced in 2007. In the same year, 612 million tonnes of aluminium are stored in productive use. The primary aluminium production in 2007 required 6 500 PJ of primary energy, as shown in Figure 16. However, these energy resources are not definitively lost, but transformed into material resources for use. Total primary energy stored in use amounts to close to 115 000 PJ. Through the use of only around 5% of the originally used energy, this metal can be made available not just once but repeatedly from these material resources for future generations. The 38 million tonnes of remelted aluminium only required 250 PJ gaining a product with the same primary energy content as primary alumium. Improving the overall recycling rate is an essential element in the pursuit of sustainable development.
