Abstract
The disposal of household waste in landfills or dumps and the excessive consumption of pesticides that cause diseases and pollute the environment are problems in modern society. This work is justified by the proposition of alternative solutions that alleviate the mentioned problems. Domestic vermicomposting was presented as a treatment technique for these residues, associated with the use of compost produced in an organic garden for a single-family residence with five inhabitants, for a period equivalent to 3 months. For vermicomposting, the worm of the species Eisenia fetida was used, not using citrus residues, strong seasonings, and leftovers from cooked or fried foods to minimize problems with earthworms and vectors. Treated residues were weighed, as well as all vegetables and legumes as harvested. As a result, it was estimated that if at least 10% of the population of Fortaleza adopted such practices, around 15,646.85 tons/year of waste would no longer be sent to the landfill, equivalent to an estimated savings of R$ 3,129,369, 96 / year. Regarding the economy with food taken from the organic garden nourished by the fertilizer produced in the residence, it was estimated a value of R$ 221.75/month for the family. It is concluded, based on the values found, that the techniques are economically viable.
