Economic feasibility study of vicera oil reusing for biodiesel production in a chicken meat processing company in Minas Gerais

Abstract

Chicken meat production in Brazil has increased significantly in recent years, contributing to the country's economic growth, given the prominent participation of agribusiness in national GDP. However, this activity generates a significant amount of solid waste from poultry processing such as feathers, blood and offal, with potential impacts on the environment. In Brazil, the proper management of industrial waste is the responsibility of the respective generators, which may represent risks to the undertaking, whether in the form of expenses with its treatment and / or final disposal, or as environmental liabilities. In this context, the objective of this work was to evaluate the economic viability of the reuse of offal oil generated in the slaughter of chickens for biodiesel production through a processing plant, a proposal supported by the Circular Economy model guidelines. For this, a waste generation diagnosis was made in a chicken meat processing company in Minas Gerais State, Brazil. The applied methodology made use of the economic viability indicators. The values ​​found from the indicator calculations were based on a predetermined rate of conversion of viscera oil to biodiesel. The indicators showed that the venture is viable, obtaining a satisfactory result such as the 1.2 year payback. Thus it was possible to analyze the current and future scenario, showing that the scenario proposed by this work can bring gains to the company object of study.
