The ideal solution for the separation and collection of waste in large cities

Lots of large cities are hesitant... However, there is a great solution for waste collection in large, urban areas: Mechanical and Biological treatment (MBT) by Orgaworld. This is one of the only reliable solutions which results in maximum recycling: our facility in Oudehakse has been processing over 200,000 tons of waste every year for the past ten years with a recycling percentage of over 90%!

The benefits speak for themselves

After many years with MBT and the separate collection of waste in large cities we can only highlight the benefits...

  • One Bin Policy:
    • there is no need to separate waste at the source
    • no extra collection which means no extra costs
    • a reduction in transportation (lower CO2 emissions)
  • Zero Waste Option:
    • high recycling percentage (up to 100%)
    • production of renewable raw materials and fuel
    • lower costs
  • Perfect match with organic waste recycling

A concise breakdown of MBT

We use our own MBT technology which consists of three main processes when processing mixed household waste:

  1. mechanical separation: the mixed waste is separated using seven ballistic infrared magnets and a conveyor belt where it is divided into a number of sections (see figure 1);

  2. wet washing: the heavy fractions (glass and grit) of the waste are separated from the organic waste using a washing process. The remaining organic waste, now a pumpable slurry, is then stored in a buffer tank (see figure 2);
    Figuur 2: Natte wassing.

  3. anaerobic digestion: the organic fraction is converted into biogas in the processing tank and is then used to create into green electricity and heat using the generators. The remaining solids, or digestate, is dried out so that it can be used for incineration and by that energy production. (see figure 3)
