MBT – Mechanical-biological treatment
“A mechanical biological treatment system is a type of waste processing facility that combines a sorting facility with a form of biological treatment such as composting or anaerobic digestion. MBT plants are designed to process mixed household waste as well as commercial and industrial wastes.
The terms mechanical biological treatment or mechanical biological pre-treatment relate to a group of solid waste treatment systems. These systems enable the recovery of materials contained within the mixed waste and facilitate the stabilisation of the biodegradable component of the material.”

EnviCare® Engineering GmbH has already carried out extensive laboratory and pilot tests together with the AWV Liezen and the AWV Hartberg in 1997-2000. It could be shown that the relevant Austrian limit for direct deposition on landfills of 6,600 kJ/kg is met. Also a simple, reliable and inexpensive method for controlling the biological treatment was developed.
Upscaling the model
Based on this work, the large-scale plant MBA Liezen, with a capacity of 25,000 t/a, was designed and built, making use of functional tendering. Subsequently the construction and commissioning phases were supervised during the years 2002-2003.
