Investimento em sistemas de energia renovável no agronegócio com base nos princípios da economia circular

Abstract

The objective of this thesis is to develop a tool to aid in the decision of investments in renewable energy systems in agribusiness based on the principles of circular economy. Therefore, in the theoretical framework, the following were considered: circular economy, renewable energy, investment project analysis and decision making. The methodological procedures were composed of three phases. The first phase consisted of a systematic review of the literature and background on the subject, identifying the decision making models for investment in renewable energy and the necessary disbursements for this type of investment. Circular economy considerations were maintained in these decisions and the identification of available circularity measurement models was maintained. In phase two, the design and structuring of the tool took place. Economic viability indicators were defined (Net Present Value, Internal Rate of Return, Payback and Scenario Analysis) and circularity measurement indicators for energy producing companies (fixed assets, water and energy) based on the Circulytics tool. The integration of the rankings of the indicators (feasibility and circularity) is carried out using TOPSIS, considering equal weights for the two indicators. The third phase comprised the application of the tool for validation and necessary adjustments. As a main result, the tool enables the investor to identify the best option for decision making considering both the economic viability and the circularity of the project.
