An ammonia capture and recovery system comprises five process steps, including an ammonia removal step, an ammonia recovery step, a product granulation step, a granulated product wax-coating step, and a granulated product encapsulation step. These steps are modular in that multiple approaches are valid for each step if it meets the process requirements for the next influent. Also, a method of taking ammonia-containing wastewater and producing several water fractions (preferably of decreasing volume and increasing purity) and a time-release ammonium-containing fertilizer, resulting in a sustainable nitrogenous fertilizer product that reduces fertilizer use and subsequent nutrient runoff while being produced from wastewater and not fossil fuel or hydrogen sources.

Animal waste contains most of the essential nutrients required for plant growth. However, animal waste also contains microbes that convert urea to ammonium ions, nitrification of the ammonium ions to NO2 and NO3 and denitrification of NO.sub.2 or NO.sub.3 to N.sub.2. N.sub.2O is produced as an intermediate of nitrification and denitrification processes and N.sub.2O is a 300 times more potent greenhouse gas than CO.sub.2. The instant invention discloses low-cost, fluid suspension compositions comprising a combination of urease, nitrification and denitrification inhibitors that decrease the loss of nitrogen from animal waste and lessen the biological formation of the greenhouse gas N.sub.2O. These compositions comprise nitrogenous phosphoryl compounds and nitrification inhibitors that utilize manufacturing processes for the formation of low cost, fluid suspensions comprising one or more inhibitor particles selected from the group consisting of urease inhibitor particles, b) nitrification inhibitor particles, and c) fused particles.

A process for separating heavy metals from a phosphoric starting material includes, in a step (i), heating the starting material to a temperature between 700 and 1,100° C. in a first reactor and withdrawing combustion gas. In a step (ii), the heated starting material at the temperature between 700 and 1,100° C. is transferred to a second reactor, chlorides of alkaline and alkaline earth metals are added and process gas is withdrawn.
