Mechanical-biological waste treatment (MBT technology) is a material-specific process. Mixed (residual) waste is separated into various fractions, each of which is treated and, if possible, recycled in a way that is customised to its properties. The core elements of MBT are mechanical or physical separation technologies and the biological treatment of biodegradable waste components unless they are diverted to recycling (eg paper). Most MBT plants divide their input into a fine fraction for biological treatment and a coarse high-calorific fraction that undergoes extended mechanical treatment.
This report examines and compares available MBT technologies.
The recovery of organic materials from solid waste streams has several recognised environmental benefits such as reduced methane emissions from landfill and a lower risk of groundwater impact from landfill leachate.
The Authority considers the diversion and beneficial use of organic waste from landfill to be a priority.
