摘要: This study evaluated odor generated during the first stage of composting process in a dynamic respirometer using different raw materials such as organic fraction municipal solid waste (OFMSW), mixture this with orange peel (OFMSW-OPW), sewage sludge bulking agent (SL) and strawberry extrudate, fish waste, (SFWSL). The combination near infrared reflectance (NIR) spectroscopy chemometric analysis is proposed to correlate chemical composition operational variables each material process. temperature, respirometric index (DRI), airflow (Q), concentration (OC) emission rate (OER) were monitored. Adequate linear correlations obtained between temperature DRI for compostable substrate within confidence interval 10% 30%. Operational statistically analyzed by principal component 87% total variance explained from which substrates clearly grouped. Near provided material, was found be an advantageous technique predict relationship emissions absorption bands. Odor also predicted multivariate regression, being most influential variables.
