Abstract

NPHarvest is a technique developed at Aalto University to recover nutrients from liquid waste. This technique has successfully recovered the Nitrogen (N) and phosphorus (P) from different types of liquid waste at the laboratory scale. After technical success in the laboratory scale, this is upscaled to pilot-scale continuous process (100 L/hour). Besides technical study, this project also studied the market potential for the NPHarvest technique and its end products in Finland. In this study, we are developing a business model for the NPHarvest technique startup company and its potential users.


The value proposition showed how to create value for the waste using the NPHarvest technique. Several alternative business models are developed for the NPHarvest technique as well as liquid waste producing companies. This study included mainly two types of a business model; (1) capital purchase business model (the liquid waste producer company purchase and install the NPHarvest unit in their process) and the (2) service business model (the liquid waste producer company only buy the service of liquid waste treatment from NPHarvest company). The licensing business model is only for the NPHarvest startup Business Company. In order to make nutrient recovery technologies more attractive, some motivation activities need to be done from an institutional level.
