1. A method for processing material, comprising the steps of:
dehumidifying incoherent material;
transforming said dehumidified incoherent material into molten material;
using said molten material for moulding;
measuring at least one value of at least one physical-chemical feature of said dehumidified incoherent material; and
adjusting a pressure (PLIM) of said molten material according to said measured value of at least one physical-chemical feature;
wherein the adjustment step comprises increasing or decreasing a set point value of said pressure as a function of the measured value.
