More out of mechanical biological treatment

Fundamental to mechanical biological treatment (MBT) is how effectively valuable materials are retained and impurities sorted out, as well as how much energy is generated from the processed material by composting, anaerobic digestion and biodrying. Improving both mechanical and biological parts of the process can have a significant impact on the profitability of the whole plant.

Mechanical biological treatment plants use municipal solid waste, commercial waste and industrial waste as raw material. In the customary process, waste is screened and sorted, and all valuable materials are recovered or used in energy production.

A straightforward way to improve the profitability of an MBT plant is to tailor the waste material to the optimal size for both separation and energy production right at the beginning of the process.

Proper pre-shredding turns mixed waste into an easy-to-process grain size at once, no matter if it is packed in plastic bags or contains bulky objects. Pre-treated material is faster to screen and sort, and if the process is well designed and equipment properly adjusted, the material also has the right size for biological treatment to generate the maximum amount of energy.
