Diretivas de projeto e metodologia de implantação de um sistema aquapônico sustentável

Abstract

With the worldwide population growth, the search for technological innovations that increase food production without compromising the environment is imperative. It constitutes an important theme discussed in the Sustainable Development Objectives. In this scenario, aquaponics, which combines vegetable production with fish production, stands out to contribute to sustainable development. It improves food production, promotes food security and ensures the availability and sustainable management of water. However, the effectiveness of the system depends on an energy-consuming pump and aeration mechanism, which is characterised as a hindrance to the technique. The objective of this research is to come up with a pilot aquaponics-system for a Higher Education Institution to find an alternative for energy maintenance. The project needs the construction of an aquaponics laboratory with 80 m². It needs a tank for the cultivation of tilapia destined for consumption and ornamental carps, grown as decorative fish. It further needs horizontal and spiral hydroponic channels for the cultivation of different species, vegetables and fruit. Also required is a biological filter tank flooded with expanded clay and papyrus plants. The drainage system for the hydroponic gutters will be powered by photovoltaic energy and the aeration system will be powered by a wind turbine. The water that feeds the system will come from the rainwater harvesting cistern of the construction. It is hoped - with this proposal - to implement an energy-efficient aquaponics system for food sustainability.
