Characterization of Municipal Solid Waste to estimate biodegradability for mechanical biological pretreatment and landfilling
Résumé
Characterization of municipal solid waste is one of the key success of the development of biological methods of valuation of fermentable organic fractions. The present study investigated the biochemical and biodegradation characteristics of several household waste fractions and materials. The correlation between aerobic test (BOD on suspended solid samples) and anaerobic test (BMP on suspended solid samples) indicated that the biodegradability of the organic matter contained in the solid materials was related to its properties. It is also suggested that both methods could be used to evaluate the biodegradability of organic matter in waste materials. No significant correlation occurred between biodegradability with variables from leaching test (Soluble COD, conductivity, soluble fraction in solution neutral detergent) and Van’t Soest fraction cellulose or hemicellulose, excepted for the non-extraction RES fraction.
