The invention relates to an optimized nutrient salt composition comprising elemental sodium and potassium in the ratio of 1:1.5 to 1:7 preferably 1:3 and elemental potassium to chloride in the ratio of 1:1 to 1:1.5 and method of preparing the same. Said composition can be optionally added with a) salts of calcium and, or magnesium as taste stabilizers, b) carbohydrate like polysaccharide, oligosaccharide, disaccharide, monosaccharide to produce energy electrolyte powder, c) food additives selected from anti-caking agents, crystal modifying agents, flavoring agents, flavor modifying agents, coloring agents and or any other food additives and d) nutrients selected from proteins, amino acids, carbohydrates, sugars, fat/oil, fatty acids, vitamins, minerals and water. Said optimized nutrient salt composition can be used as food, food ingredient, food supplement, table salt, preservative, food additive, seasoning agent and ingredient for oral rehydration fluid, intravenous fluids, beverages, energy drinks, sports/study drinks and stimulant drinks for humans, pets and livestock and for plant nutrition.

The specification describes a system and process for treating a sludge or slurry to produce biochar. The sludge or in slurry may be digestate produced by an anaerobic digester that receives waste activated sludge from a wastewater treatment plant. In a process, digestate is dosed with metal ions, dewatered, and pyrolized. A corresponding system includes a reactor, a dewatering unit and a pyrolysis unit. In an example, the digestate is air stripped in the reactor and a metal salt is added to it. The metal ions form precipitates in the digestate that remain in the biochar. In some cases, a precipitate such as struvite is formed that also increases the phosphorous content of the biochar. The biochar may be used as a soil amendment, wherein the metal and phosphorous are beneficial to the soil.
