Resumen:
Agro-industrial wastes generally have large concentrations of organic materials which, if handled improperly, can pollute and / or contaminate soil, water and air. Composting processes have been established as efficient ways to minimize environmental problems and to reduce the volume of organic waste disposed of in an environmentally incorrect way. The main objective of this work is to quantify the organic solid waste of horticulture of the Public Market of Pombal -PB, as well as to investigate the viability of organic compost production through the use of the aerobic composting technique in the open environment. For this, It was performed daily weightings for four weeks of the organic solid waste generated in the horticulture sector of the Public Market of Pombal-PB, in addition, a compost pile was assembled with the organic residues collected at the study place and the degree of maturation of the final organic compound was verified. The final diagnosis resulting from the research was that an average of 82.12 kg of organic waste is produced daily. To evaluate the maturation of the compound, the parameters of temperature, C / N ratio, and electrical conductivity epH were used. It presented satisfactory maturation results when compared to that determined by Ordinance No. 01/83 of the Ministry of Agriculture, Livestock and Supply, indicating that these simple methods are considered safe for verification of composting processes conducted in regions subject to semi-arid conditions, being efficient for the treatment of agro industrial residues.
