At MBT and SRF production facilities, the waste formerly landfilled passes through mechanical and biological processes selectively. The Recyclable, bio-organic and inflammable materials are sorted by passing through the mechanical treatment machines. The combustible materials are used as fuel to make the energy, for example, in power plants, as a form of SRF (Solid Refused Fuel) after shredding and sorting PVC materials out which are the sources of Dioxins. Bio-organic material is treated by the bacteria to make the biogas. Only the remainings (inert, sand, stone..) are dumped into the landfill which will be max 5% of the waste.
