BMW Group Plant Landshut light metal foundry recertified by Aluminum Stewardship Initiative (ASI)

The BMW Group’s light metal foundry in Landshut has once again been certified by an independent party for its sustainable use of aluminum—meeting the standards of the aluminum Stewardship Initiative (ASI), an international non-profit organisation supported by environmental and industrial associations, aluminum producers and processing companies. The ASI defines sustainability criteria for an environmentally and socially responsible aluminum value chain.


The auditing criteria require evidence of material stewardship, such as a holistic lifecycle analysis for the company’s own products and a comprehensive recycling strategy, as well as compliance with standards for transparency, overall management and corporate integrity. The initial successful certification in accordance with the criterion of material stewardship took place in December 2019.

Sustainable extraction of raw materials and conscious use of resources play a key role for our in-house component production and our global supplier network. Sourcing aluminum produced using solar power for our in-house component production lowers our CO2 emissions significantly. The circular economy is also key to reducing emissions and conserving natural resources. Going forward, the aim is to build our new vehicles with 50 percent secondary raw materials.

Landshut’s light metal foundry, the BMW Group’s only production facility for light metal casting in Europe, is among the most advanced, most sustainable foundries in the world. Due to its use of inorganic sand cores, the casting process is virtually emission-free. The light metal foundry began sourcing aluminum produced using solar power in 2021.


Since producing aluminum is highly energy-intensive, the use of green power such as solar electricity offers considerable potential for reducing CO2 emissions. The tens of thousands of tonnes of solar aluminum supplied in this way meet more than a third of annual requirements for the light metal foundry at Plant Landshut.

Along with steel, aluminum accounts for the largest share, by weight, of the materials used in BMW Group vehicles. Around two-thirds of the aluminum used in Landshut comes from a recycling loop, with almost two thirds of this from the foundry’s own closed loop. In this way, the BMW Group is consciously reducing its use of more CO2-intensive primary aluminum in favor of a CO2-optimized recycling loop. Green power is also used to produce it.

The BMW Group has a long tradition of responsible use of aluminum. For more than ten years, the light metal foundry has been working with local processors to implement a recycling loop for post-production scrap metal salvaged from the foundry process. The decisive factor here is clean separation of aluminum residues. Residues are collected from all casting and mechanical processing stations according to type, so materials with different compositions are not mixed. This means that, after reconditioning, aluminum waste can be reused to manufacture the same components.

Last year, employees at the light metal foundry produced around 3.3 million cast components with a total weight of more than 73,000 tonnes. The scope of production includes engine components such as cylinder heads and crankcases, components for electric drive trains and large-scale structural components for vehicle bodies.

The responsibility of the BMW Group extends beyond recycling to the aluminum used. The conditions under which the raw material bauxite is extracted by open cast mining and processed in countries like Australia, Brazil and Guinea are also important to the company.

The BMW Group is in direct contact with aluminum suppliers and recycling partners in an effort to gradually expand ASI certification to the entire material cycle—starting with the producing mines.
