a) How other entities participate in the project and possible collaboration: Ms. Apple Suplido of De La Salle Araneta University said that technology on the production of struvite can be shared so that other teams can learn more about the technology. The NexCities team is willing to partner with groups outside the Philippines to see how the project can be implemented in other countries.
b) On the cost of struvite compared to existing fertilizer in the market: In the pilot-scale, struvite is still more expensive than those available in the market but it is expected that in large-scale production, the cost can be considerably lowered. A sound and sustainable business model will also contribute to the lowering of prices. NexCities also intends to come-up with the cost benefit analysis to measure the viability of the project.
c) On the effectivity of struvite, the process and other concerns: Analysis on the helminths and other additional biological parameters will also be included in the next phase of the study. Upon testing of the recovered fertilizer to a variety of plants, the Salikneta team showed that recovered fertilizer is as good as the commercial fertilizer. Air drying can also be considered instead of sun drying to avoid volatilization of some nutrients. Another concern was how to recover more sewage for production of struvite. On communication: it is very important to talk to stakeholders to let them understand the project and how they can participate.
d) On social acceptability: Conduct more studies on this aspect
e) On Funding: PCIEERD and SEARCA encouraged the project team to check out their grant facilities.
