Abstract: An explosive emulsion composition of the water-in-oil type, comprising



between 80 wt. % and 95 wt. % of an oxidizer phase composition comprising

at least 40 wt. % of ammonium nitrate (AN), and
at least 15 wt. % of calcium nitrate (CN), and optionally one or more other secondary nitrate salts,


between 5 wt. % and 20 wt. % of an 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,

characterized in that the fuel composition comprises between 20 wt. % and 100 wt. % of a straight vegetable oil (SVO), and

wherein the explosive emulsion composition is stable and has a viscosity between 25,000 cP and 125,000 cP, as measured with a Brookfield viscometer with spindle size 7 at a frequency of 20 rpm at 30° C.

Abstract: The present application relates to a method for removing a contaminant from wastewater from industrial fertilizer plant. The method comprises the steps of concentrating the wastewater, of electrolyzing the wastewater and of recirculating the electrolyzed wastewater to the fertilizer plant. The present application further relates to a system arranged to perform the method according to the present application.

Abstract: The present disclosure concerns fertilizer particles comprising calcium nitrate and potassium nitrate. It is found that fertilizer particles comprising 43 to 47% w/w calcium nitrate and 46 to 54% w/w potassium nitrate can be produced by melt granulation. Due to undercooling problems, such particles were not expected to be suitable for industrial production by melt granulation. However, the present disclosure provides a composition which forms a low viscosity melt with short solidification time. This was successfully achieved by reducing the water content of a fertilizer melt comprising 43 to 47% w/w calcium nitrate and 46 to 54% w/w potassium nitrate to less than 3% w/w of the melt.
