For casting aluminum engine components, the use of bonded sand cores is required. Recent developments allow the use of low-emission inorganic binders (sodium silicate) in series production. In this thesis, a regeneration method for series production is developed based on an adjusted chemical testing of moulding materials, whereby the repeated use of the accumulated inorganic used sand is possible. A closed material circuit is an important requirement for a widespread and economic use of this environmentally friendly technology.
