Recovery of fertilizers from human urine; which is a waste product is very important because the use of poor quality/ inorganic fertilizer is known to cause negative consequences. First, these inorganic fertilizer products are very expensive and many people cannot afford them. They are not easily available in comparison with organic fertilizers. Most inorganic fertilizers are often produced or extracted from petroleum products and can therefore have a negative impact on the environment. Inorganic fertilizers do not increase the organic content of the soil and are easy to overuse, thereby damaging plants. They will also make the soil more acidic and the soil will need pH adjustment. When inorganic fertilizer is used, nutrients in the soil can easily be depleted. Some literature reviews of similar studies point out the presence of heavy metals in plants using inorganic fertilizers. The population is growing and more food production is needed; Therefore, we will not rely on inorganic fertilizer products to survive. Additionally, there is no control over the discharge of this waste (urine) into the aquatic environment which can cause serious damage to the environment and is of great concern as it can damage the water supply, could be harmful to aquatic life or cause diseases if the water is used inappropriately; therefore needs to be channeled properly for optimal use.
Due to the detection of these problems, it is necessary to use organic fertilizers (such as struvite obtained from human urine). Struvite, used as fertilizer, can be easily produced by small businesses at a low cost. In other words, it is cheaper because they can be made from simple waste. They are generally safe and have low environmental impact. Generally speaking, plant or animal materials add organic substance, which retains moisture and supports a healthysoil microbiome.
