The present disclosure generally relates to a water-in-oil emulsion explosive composition, comprising an organic phase and an oxidizer phase at least comprising ammonium nitrate, wherein at least 50 wt.%, or even 100 wt.% of the normally used non-renewable oil in the organic phase is replaced with one or more chemically processed renewable oils and/or straight vegetable oils or straight animal fats. The present disclosure relates to an explosive emulsion composition of the water-in-oil type is disclosed, comprising between 5 wt.% and 20 wt.% of an organic phase in view of the total weight of the emulsion composition, the organic phase comprising * between 12 wt.% and 50 wt.% of one or more emulsifiers, * between 50 wt.% and 88 wt.% of a fuel composition, in view of the total weight of the organic phase composition, wherein the fuel composition comprises between 20 wt.% and 100 wt.% of a hydrotreated vegetable oil (HVO), in view of the total weight of the fuel composition; and between 80 wt.% and 95 wt.% of an oxidizer phase in view of the total weight of the emulsion composition, comprising * at least 40 wt. and up to 80 wt.% of ammonium nitrate (AN), and * at least 5 wt.% of one or more secondary nitrate salts, in view of the total weight of the oxidizer phase composition.
