BMW’s Landshut plant outside of Munich will become the world’s first foundry with emission-free sand core production, the German company announced today. The light-alloy foundry is introducing a new production method for gravity die-casting.
Instead of conventional organic binders long in use in castings, newly developed inorganic binders will be used, which generate virtually no pollutants during the process.
BMW claims the plant’s emissions from combustion residues will be reduced by 98%. As a result, the plant will completely decommission its current waste air treatment systems by 2010.
The new method could be of enormous significance in the business as automobile makers continue to shift into lighter weight aluminum and magnesium materials to increase fuel economy and decrease emissions of carbon dioxide.
