that machine is the sludge injector, this place has a contract to remove 7000 tons a year from the local sewage works and it is then injected on to short rotation willow coppice, it was made in denmark aswell and to the best of my knowage is the only 1 in ireland and maybe the uk. The trailers carting the sludge are full spec 16 ton kanes with cross engineering additions which include a pick up hitch, special rear door, aguer inside to move the sludge to the small door in the rear and all controls at the back corner.
