Other materials which may be extracted from MBT processes include glass, textiles, paper / card, and plastics. The most common of these is glass, which may be segregated with other inert materials such as stones and ceramics. These materials are typically segregated and arise as the “dense” fraction from air classifiers or ballistic separation (see Table 2 on mechanical waste preparation technologies). This dense fraction could find application for use as a low grade aggregate; however this would be subject to achieving a suitable quality material. This mixed material from some processes has found application as Alternative Daily Cover (ADC) at landfill sites, though this would not count towards recycling performance or diversion from landfill
