Using a techno-economic model of the process, we calculated the total annual cost (TAC) of the biofertilizer production facility based on a 15% DROI and a 15-year process life. The revenues generated by the natural gas and electricity produced by the process are based on typical market prices. The price of the cyanobacteria biofertilizer is based on the cost of obtaining an equivalent amount of nutrients from diammonium phosphate (DAP), a commonly used synthetic fertilizer. Revenue can either be in the form of a direct payment for products that are exported off-site or in the savings associated with reductions in the amounts of utilities and fertilizer that are purchased from the market when the products are consumed onsite. The difference between the product revenues and the TAC is covered in the form of a phosphorus recovery charge (PRC), which is interpreted as a service cost per kg of P captured by the process. We compared this service cost with the socioeconomic cost of P runoff reported in the literature. This provided context for the PRC and allowed us to gauge if the process was able to provide a net benefit to society. The PRC served as the primary performance metric in our analysis.
