Assessment of struvite and K-struvite recovery from digested manure
Human population has had an impact on the natural phosphorus’ cycle, a limited resource, and the predictions show that this resource could be exhausted in 100-250 years. Therefore, the actions for the coming 10-25 years must be focus on the recovery of phosphorus, for example, from renewable sources...

| Resumo: | Human population has had an impact on the natural phosphorus’ cycle, a limited resource, and the predictions show that this resource could be exhausted in 100-250 years. Therefore, the actions for the coming 10-25 years must be focus on the recovery of phosphorus, for example, from renewable sources such as manure. Thus, phosphorus recovery as struvite or K-struvite from manure is investigated, as the recovery of the essential nutrients is considered to be a significant breakthrough for assuring long-term and economical phosphorus supply, while recovering a valuable slow-release fertilizer. Therefore, this PhD thesis proves the feasibility of recovering nutrients from manure, a complex matrix with high concentration of solids. Furthermore, aims to bring innovation and insights on the sustainable recovery of fertilizers (i.e. ammonium and/or potassium struvite) from swine manure |
