Improving waste management practices though a voluntary
grouping of seven local authorities in Northern Ireland.

Mechanical Separation

The Mechanical part of the treatment happens in this phase of the process.

The majority of the waste is still contained within bin bags. These are taken to a shredding chamber where they are opened.

Recyclable material is then removed using a variety of methods.

Magnetic sorters, screen separators and optical separators divide the metals, paper and plastics from the other waste.

MBT can involve various phases of both Mechanical and Biological treatment, but the Biological part of the process is usually Anaerobic Digestion or In-Vessel Composting.

We’ll examine both of these in the next section.
