Residues from poultry farms include a mixture of manure, litter materials (e.g. wood sawdust or rice straw), dead
chickens and more. Since the mixed litter and manure has an high nutritive potential for land cultivation, the most
common use of such residues is the spreading of fields of rural area in order to achieve soil restoration [1, 2]. The
91/676/CEE Directive fixed the maxima nitrogen contents releasable into the soil and after these constraints [3] ,
alternative uses (preferably energetic valorization) had to be applied. The use of this waste product has been
historically limited to the surroundings of the place of generation because of its inherent low density. Compaction is
one possible way to enhance the storage and transportation of the litter
