<p>There is disclosed a method for utilising powdery material, particularly combustible powdery waste material, e.g. paint powder or paint abrasive dust, where the powdery material in a way known per se is rolled or compressed to tablets, pills or briquettes as the rolling or compressing occurs in such a way that so high frictional heat is produced in order that the surface of the tablets, pills or briquettes 'fuses'. In a very simple way it hereby becomes considerably easier to dispose of and simultaneously to utilise environmental waste of the said type as the briquetted waste materail may be used a fuel which is easily fired into e.g. incinerators or combustion units of power stations, and which is now completely without dust explosion risk.</p> |
