dc.description.abstract The need to produce bioproducts useful for the human wealth derived from microalgae, such as proteins, lipid and carbohydrates is gaining importance in recent years. In spite of the broad availability of technologies for these kinds of processes there are uncertainties regarding the investment required to build a microalgae processing plant in Puerto Rico. To address this issue, economic analysis for five selected process case scenarios able to produce 222 million pounds of microalgae-derived paste per year were performed. Results indicate that operational costs are predominant in our analysis due primarily to the cost of utilities. In addition, the combination of pond site, dewatering, freeze drying and supercritical CO2 extraction were the most effective in terms of investment ($80 million) and operational costs with an annual cost of manufacturing of $0.65/lb for the microalgae paste.
dc.description.abstract La necesidad de producir bio-productos para el bienestar humano derivados de microalgas como lo son las proteínas, lípidos y carbohidratos ha cobrado importancia en años recientes. A pesar de la amplia disponibilidad de tecnologías para estos tipos de procesos, aún existen incertidumbres en respectó a la inversión requerida para construir una planta de procesamiento de microalgas en Puerto Rico. Para atender este asunto se realizó un estudio económico de cinco casos diseñados para la producción de 222 millones de libra de pasta derivada de microalgas. Nuestros resultados indican que los costos operacionales son predominantes para efectos de nuestro estudio debido primeramente al costo de las utilidades. Además, la combinación de una charca, concentración por desaguado, liofilización y extracción de CO2 supercrítico demostró ser la más efectiva en términos de inversión ($80 millones) y costos operacionales con un costo de manufactura de $0.65/lb de pasta de microalgas.
