which contains valuable nutrients like nitrogen and phosphorus, can be applied to soil and used as fertiliser for crops. Though valuable, urine is sometimes difficult to transport and store and it does not have a pleasant odour. To overcome these issues, struvite can be produced. Struvite (MgNH4PO4•6H2O) has many of the fertilising properties of urine with several advantages: the volume and weight are reduced, it can be stored in a compact form and it is easy to handle, transport and apply- especially in a granulated form.
