 | Mechanical Biological Treatment (MBT)
MBT is a generic term for a number of processes, which are combined to process waste. It can be used to process mixed, black-bag waste or source separated waste. MBT processes typically include a series of screens and conveyors to separate different fractions of waste (the same as a materials recycling facility MRF). The biodegradable fraction is then processed using anaerobic digestion or in-vessel composting technologies.
The products produced will be dependent on the configuration of the technologies used but can include; refuse derived fuel (paper, plastics, etc.) separated recyclables (metal, glass) compost-like material and if anaerobic digestion is used then electricity can be produced, which can be sold to the National grid for an enhanced tariff.
Whether viable markets can be found will be dependent on the quality of the products produced. If not viable markets cannot be found then the products will have to be landfilled.
