Propuesta para la valorización de AVU’s (aceites vegetales usados), a través de la obtención de velas artesanales usando diseño de mezclas con vértices extremos

Abstract

The environmental problems caused by the mismanagement of waste from used vegetable oils (AVU) is a current concern, since it directly affects the soil and water. Water pollution by AVU has an impact on public infrastructures and the environment. For these reasons, in this titling project the study of AVU's was proposed as raw material for obtaining artisan candles. To carry this out, used vegetable oil collected by the ETAPA company was used. This was deodorized through maceration in coffee beans. The deodorized AVU was used in different tests to obtain candles. The percentages of AVU, stearic acid, perfume fixative, aromatic essence varied in each formulation according to a design of mixtures of extreme vertices. For the preparation and evaluation of the candles obtained, the corresponding ASTM standards were followed. In addition, the organoleptic characteristics of the candles were evaluated. The formulation with the best score corresponded to: 2% Perfume Fixer, 10% Aromatic Essence, 68% AVU and 20% Stearic Acid. The candles obtained with this formulation met the quality standards established by ASTM standards, obtaining an eco-friendly product from these residual oils.
