The invention provides a process for the manufacture of an additive concentrate which comprises particles of size from 5 microns to 10 mm and a binder including the steps of: (a) mixing the particles and the binder in the dry state; (b) pressing the resulting mixture, optionally with heat sufficient to soften the binder, but insufficient to form significant melting of the particles so as to form a coherent body; and (c) optionally comminuting the resulting body. |
