From Waste Treatment
Within the scope of the municipal solid waste management strategy (MSW), the Municipal Green Waste Composting Center is installed, installed in the Municipal Garden, whose main objective is to transform the organic matter into a natural fertilizer (compost), through a process called composting.
Composting is a biological process, in which microorganisms transform organic matter, such as grass clippings, leaves and branches, into a natural fertilizer, similar to soil, which is called compost and whose purpose will be to work as a corrective for the soil and fertilizer. for plants. The composting of green waste has numerous advantages, including:
- Decrease in the amount of waste to be landfilled
- Obtaining a compost, used as a soil corrective and as a natural fertilizer for plants, which reduces / eliminates the use of chemical fertilizers
The waste sent to the Municipal Composting Center for Greens comes from cleaning the municipal green spaces and also from the maintenance of private gardens, which are collected through the collection system of bulky objectives (Tuesday), carried out by the Urban Hygiene Service .
As not all residues have the same dimension, in order to facilitate their decomposition by microorganisms, their size must be reduced. For this purpose, larger residues are reduced to small pieces by a chipping machine, making their size uniform, so that they are subsequently introduced into the compost piles. Large residues, which are not shattered (for example resulting from tree pruning) are broken into wooden chips and stored, to later be used and recovered, transforming into heat energy for heating elementary schools. . Once in the compost piles, there is a natural process of transformation of organic matter.
However, to ensure its effectiveness, it is necessary to control factors such as temperature and humidity, which can be done through the adoption of simple techniques, such as watering the batteries with water and aerating them by turning.
