Leicester MBT

Our mechanical waste treatment plant at Hoods Close, Leicester is based on ball-mill technology which is used to process the “black-bag” household waste collected within the City of Leicester.

The waste is subject to initial size reduction via a slow speed shredder, which also opens the bags so that the waste then becomes accessible to subsequent stages in the process, and increases the density of the waste prior to input into the ball-mill.

The ball-mill rotates at a speed of about 30 to 40 revolutions per minute and steel balls inside shreds and tears the waste to homogenize the material. The prepared waste is then screened through a trommel to extract food and other small particles of organic waste (which are sent to anaerobic digestion), metals are removed, and the majority of the remaining material is shredded to produce a solid recovered fuel. The remaining material comprising grit, soil, glass etc is sent to landfill.

The plant has a capacity of 150,000 tonnes per annum and achieves a landfill diversion rate of more than 80%.
