Abstract

Investments in sustainable food production technologies which consume less water, nutrients, and energy are needed to meet the growing demand for food. The integration of biofloc technology with plant production in a decoupled FLOCponic system (DFP) is an alternative for it. Mathematical models are excellent tools to demonstrate the real efficiency of this system and understanding the dynamics of its natural resource use. Based on these premises, the objective of the present project is to evaluate the resource-efficiency of multi-loop decoupled FLOCponics for food production. The project will be developed in three stages. The first stage will comprise of developing the theoretical framework and an analysis of previous data; the second stage will be experimental, it will be evaluated the use of mineralizers to produce lettuce in three-loops systems using the effluents from tilapia production in DFP; and, the third stage will comprise of a theoretical model based on the results of the previous experiments. It will be described and understood the system dynamic using material and energy balances of tilapia and lettuce production in DFP. In summary, this project envisions a full understanding of resource efficiency by the innovative system proposed and developed at the Aquaculture Center, Brazil, as part of the doctoral thesis. The results will be disseminated in scientific publications and resulted in obtaining of a double degree by the beneficiary (Unesp and Wageningen University). (AU)
