Main raw material involved sources of Nitrogen, phosphorus and potassium that will change depending on formula and costing.
Water, sulphuric acid and steam are used as binders. Changing ratios on them, parameters as viscosity of binding blend can be optimised. Temperature on granulator will be also controlled in this way.
No wastes appear on this production.
Environmentally is a clean process in which only CO2 coming from burning natural gas is produced. Taking into account that final product is the nutrient for growing plants with photosynthetic function, it means that CO2 footprint will be improved.
