Diminuição do percentual de perda de substrato por contaminação no processo produtivo de inseticida biológico à base do microrganismo Beauveria bassiana com uso do PDCA

Abstract

With the growth of capitalism, there was an increase in food consumption and the number of companies offering more sustainable solutions to increase their production. Because of this, consumers began to become increasingly demanding in relation to the quality of products / services, forcing such companies to seek improvements in their products and processes, aiming at their satisfaction. One of the ways to produce food in a more sustainable way is to replace part of the application of chemicals with application of organic products. Such products are used in biological pest control, which in turn portrays that all species of plants and animals have natural enemies, which attack various stages of life of their targets. Among the natural enemies there are diverse groups such as: insects, viruses, fungi and bacteria. The second most used microorganism in the manufacture of biological insecticides is the fungus Beauveria bassiana, however, its production is complex, manual and delicate, causing a high level of contamination of the substrate used for the multiplication of this fungus. In an attempt to reduce the percentage of losses, this work presents the application of the PDCA cycle (Plan, Do, Check and Act) together with the main quality tools, to reduce the loss rate of contaminated substrate, in a biological products factory in the state of Minas Gerais. The company had a loss rate of 40.17%, and with the application of the PDCA methodology, the plant reduced its loss to less than 15.00% in the last three months of 2020, indicating that the methodology was effective in reducing the loss of substrate contaminated waste and expenses with the discarded substrate, improving the company's financial results.
