Composting and vermicomposting as an alternative for treatment and disposal of organic waste
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2019, Vol 14, Issue 2
Abstract
The gray water footprint (GWF) is defined as the volume of fresh water needed to dilute Soil of semiarid regions naturally present low fertility, hampering plant growth and productivity, increasing production costs due to investments in fertilizers and agricultural pesticides. In addition, overall, there is a great waste of food. In view of this scenario, the aim of this work was to evaluate the reuse of organic waste for the production of an organic compost by means of composting, followed by vermicomposting. The experiment was carried out in two stages (composting followed by vermicomposting), at the Federal Institute of Education Science and Technology of Ceará Campus Maracanaú. Organic food residues were used from the Ceará Supply Center, cattle manure and dry leaves. At 51 days after composting, the compost was placed in a tank with a capacity of 310 L, and 100 adult Californian worms (Eisenia foetida) were added, thus initiating the vermicompost process. It was concluded that it is possible to use food waste for the production of organic fertilizer. Composting followed by vermicomposting was feasible and easy to apply. The vermicomposting reduced the grain size of the compound and improved the nutritional quality of the material, increasing the phosphorus, calcium, zinc, copper and iron content.
