<p>A method of manufacturing pellets from damp digested waste material comprises putting the waste material in a rotatable drum, and turning the drum to tumble the contents until the damp waste material has formed pellets having a desired size range. A method of manufacturing a brick from damp digested waste material comprises putting the waste material in a mould, and applying pressure to the waste material to remove at least some of the water content. The pellets or bricks may be used as a fuel or as a plant growth medium or fertiliser. Another aspect of the invention provides apparatus for manufacturing pellets from damp digested waste material, comprising a rotatable drum having an opening at one end, and a screen in a side surface thereof, having openings to allow particles below a predetermined size to pass through.</p> |
