Gestão de resíduo sólido orgânico residencial em período de pandemia COVID-19

Abstract

In front of the great increase in the generation of urban solid waste, recurrent of the disordered population growth, a composting is taken as an alternative for the treatment of the organic waste fraction. In this context, the objective of this research was to evaluate a domestic composting of solid waste from a residence, using the compost produced in the cultivation of collard greens seedlings and employing domestic composting and the practice of horticulture as a sustainable and productive activity, which induces physical and mental well-being in a pandemic period. The composting process lasted 120 days and was carried out in a designed mini composter. The organic compost produced was used to obtain seedlings of two collard greens species. The sowing was carried out in a tray with fifteen cells, set up in a completely randomized design, with five treatments and three replications. The applied treatments, T0, T1, T2, T3 and T4,corresponded, respectively, to 100% soil; 75% soil and 25% fertilizer; 50% soil and 50% fertilizer; 25% soil and 75% fertilizer and 100% fertilizer. They were avalueted: germination time, leaf length, leaf width, number of leaves, seedling height, root length and stem diameter. Treatments T2, T3 and T4 showed the best performances, with treatment T2 being the one with the best results for Brassica oleracea var. Costata and treatment T3 for Brassica oleracea var. Acephala. In addition, the study was assessed as adequate by the process participants, as it aroused interest, sustainable learning and productive routines, directly influencing the maintenance of well-being during pandemic period
