Abstract

The paper presents results of a comprehensive study on characterization of mechanically biologically treated waste generated in Bangalore, India. Physical, biochemical and engineering characteristics of the waste are presented. The methodology to separate the components of consolidation which includes primary, secondary and biodegradation strains is reviewed. A laboratory scale anaerobic bioreactor depicting the behaviour of the waste in a bioreactor landfill was studied for 370 days and the settlement, gas generation and leachate characteristics were monitored. Study on characterization of waste indicates an organic content of 54% and carbon, nitrogen and hydrogen in the range of 19.28, 1.64 and 11.07% respectively. Around 20–26% of settlement and 15 L of landfill gas/kg of dry waste was observed in laboratory scale bioreactor studies. Both laboratory and small scale bioreactor test results indicate that the MSW has high biodegradable content and biomethane potential. It is prone to large settlements and has shear strength parameters comparable to those published in literature. The behaviour of waste under given conditions can be understood from the above studies and the results provide valuable data necessary for designing MSW treatment scheme which includes waste to energy systems and bio reactor landfill with gas and leachate collection systems.
