The present invention relates to a process for the treating and generating energy from biomass and a plant where the process is implemented, said process comprising the steps of (i) providing a biomass (1), and characterized by comprising the steps of: (ii) diluting the biomass (1) with a thinner up to a volatile solids content comprised between 0.5% and 1% of the volume of said biomass (1); (iii) alkalizing the biomass (1) of item ii with a basic solution (3), up to a pH comprised between 11.0 and 13.0, wherein said biomass (1) of item ii and said basic solution (3) are in a weight ratio comprised between 1 :20 and 1 :80; (iv) hydrolysing the alkalised biomass of item iii, for a time comprised between 30 and 90 minutes, at a temperature comprised between 55°C and 80°C, thereby obtaining a hydrolysed biomass (4); (v) neutralising the hydrolysed biomass (4) of item iv, through diffusion of C02 from a biogas produced by anaerobic digestion, thereby obtaining a hydrolysed and neutralised sludge (5); (vi) performing anaerobic digestion, through a first anaerobic digestor (6), of said hydrolysed and neutralised sludge (5), thereby obtaining a biogas (60), a first digestate (61), an anaerobic sludge (62).
