The task of GDA is to demonstrate sustainable development in the aluminium industry and support the industry in its attainment of sustainability. It centres on conveying the economic benefits of aluminium as a material.
The commitment to sustainability manifests itself in various ways:
- extraction of raw materials in an environmentally friendly manner
- protection of the climate and the Earth’s atmosphere
- voluntary commitment via the establishment of a close-knit recycling system with traditionally very high recycling rates
- high recycling rates with a reduction in waste and emissions.
In addition to the recycling loops for the product itself, the aluminium industry also recycles operating and auxiliary materials such as the core sand used to make the moulds required for the sand casting of engine blocks and cylinder heads, the rolling oils used in the manufacture of semi-finished products, solvent residues from processes for lacquering foil and the caustic soda needed in the production of aluminium oxide. The salts used in recycling to tie up the impurities are a further example: they are also recovered. This minimises interference with the ecosystem and encourages sustainability.
