Gryllus Assimilis: an Environmental Alternative in the Minimization of Organic Solid Waste

Abstract

The increase in the generation of organic waste and its mismanagement have a negative impact on the natural environment with the propagation of greenhouse gases, bad odors, leachate and other pollutants, so its use would bring a solution to the problems mentioned together with the generation of work, improvement of agricultural activity, the food industry, etc. The objective of the research was to minimize domestic organic waste using the species Gryllus assimilis. To do this, organic waste classified into three types (fruit-vegetables, food and the mixture of fruit-vegetables-food waste) was used. Tests were made with 100 g of residues and 15 repetitions for each type. For the reduction of residues, 200 Gryllus assimilis were used for each treatment and repetition. The reduction results were: for the first treatment 183 g, in the second treatment 187 g and for the third treatment 182 g, which on average means up to 18.7% reduction. Based on the results, it is established that the higher the number of Gryllus assimilis, the percentage of minimization of organic waste increases. In this way, this methodology constitutes a contribution to knowledge, has economic advantages and is easy to replicate in areas where Gryllus assimilis exists, with the possibility of scaling to achieve sustainable management of domestic organic waste.
