The invention relates to an integrated process for the production of fuel components starting from materials of a biological origin which comprises: (A) transformation of glycerine into an alkoxy-propanediol having formula RO—CH2—CHOH—CH2OH, wherein R is a linear or branched C1-C8 alkyl, (B) transformation of glycerine into 1,2-propanediol CH3—CHOH—CH2OH, (C) dehydration of the 1,2-propanediol obtained in (B) to propionic aldehyde, (D) reaction of part of the propionic aldehyde obtained in (C) with the alkoxy-propanediol having formula RO—CH2—CHOH—CH2OH obtained in (A) to give an acetal having formula (a) wherein R is a linear or branched C1-C8 alkyl, (E) transformation of part of the propionic aldehyde obtained in (C) to a propionate having formula CH3—CH2—COOR′, wherein R′ is a linear or branched C1-C8 alkyl. Particular components for gasolines and/or diesel are also described.
