Carbonization of urban bio waste in Sri Lanka

Abstract

The research scope was set to study the compatibility of applying torrefaction for bio-waste of Sri Lanka. For this purpose, it was decided to analyze the before and after torrefaction properties of a sample with Sri Lankan municipal solid bio waste composition; with the use of ultimate and proximate analysis. A laboratory scale reactor was made to undertake the conventional torrefaction process with N2 purging. Heat was supplied for the reactor using a 3 kW heating coil and insulations were made around the reactor to minimize the heat loss during the torrefaction. The reactor temperature was controlled to maintain at desired temperature with a maximum of 350OC using LabVIEW software.
