Mechanical Biological Treatment

What’s Mechanical Biological Treatment (MBT)

Mechanical biological treatment, abbreviated as MBT, that used to describe a number of different residual waste treatment processes that involve both mechanical and biological treatment of municipal solid waste (MSW). It is the combination of both biological and physical processes, which can be arranged in a number of different ways.

The working pricinciple of Mechanical Biological Treatment (MBT) Plant

MBT is a two stage process for MSW, after mixing and shredding, it is separated into different fractions using a range of different processes such as:

Screening – removal of larger pieces of waste;

Magnetic separation – removal of ferrous materials;

Eddy current separation – removal of non-ferrous metals such as aluminium cans;

Optical separation – separation of certain types of plastic; and

Wind sifting – removal of light materials such as paper.

MBT Concept

Initially the MBT plants were developed to stabilize the organic fraction of the MSW before landfilling, but they evolved to become complex facilities that process MSW to separate recyclables, treat the organic fraction to produce biogas and/or compost, and produce refuse derived fuel (RDF). The MBT plants accept for processing the mixed MSW as collected after source separation of recyclables and organics has been completed. The main goals achieved by the MBT are as follows:

Decrease the amount of MSW destined for landfilling and thermal treatment

Reduce the amount of biodegradable material going to landfills

Reduce landfill gas production (greenhouse gas)

Reduce landfill leachate contamination

Recover recyclables including soil amendment product

Produce solid fuel with high energy content (RDF)
