Title

AN INVESTIGATION ON IN-VESSEL COMPOSTING OF PISTACHIO RESIDUALS WITH DIFFERENT ADDITIONS

Pages

  411-420

Abstract

 Background and Objective: About 1.35×105 tons of PISTACHIO WASTE are produced in annually Iran that can result in environmental problems if managed improperly.. The purpose of this study was to investigate IN-VESSEL COMPOSTING of pistachio residuals with addition of cow manure and dewatered sludge as a recycling alternative.Materials and Methods: Pistachios wastes were combined with weight ratio of 5.5: 10 (dewatered sludge: PISTACHIO WASTE) and weight ratio of 1: 10 (Cow manure: PISTACHIO WASTE) to achieve the carbon to nitrogen ratio of 25: 1. The parameters measured were pH, EC, percentage of moisture, total and volatile solids, ash, organic carbon, temperature, and phenol. The 20th edition of SPSS software was used for t-test statistical analysis and comparing the results with standards and Microsoft Excel 2007 was used for drawing the plots.Results: During the 60-days process of IN-VESSEL COMPOSTING of pistachio residuals with addition of cow manure, the ratio of carbon to nitrogen reduced from 25: 1 to 13: 1, dewatered sludge from 25: 1 to 14: 1; phenol amount in cow maneuver decreased from 4980 to 254 ppm and in dewatered SEWAGE SLUDGE from 6100 to 254 ppm. The maximum temperature in cow manure and dewatered SEWAGE SLUDGE treatments in the composting process reached to 51.9 and 48.9oC respectively.Conclusion: Results showed that the produced compost with cow manure has a higher fertilizing value compared with the dewatered SEWAGE SLUDGE due to its better organic degradation.
