Gasification characteristics of auto shredder residue

Given the large volume of used tyre waste generated each year it is imperative that suitable re-use and disposal techniques are developed for dealing with this problem; presently these include rethreading,reprocessing for use as safe playground and sports surfaces,use as noise reduction barriers and utilisation as a fuel source. this paper reports on pilot scale studies designed to investigate the suitability of automotive waste for energy recovery via gasification. the study was carried out into auto shredder residue,which is a mixture of three distinct waste streams: tyres,rubber/plastic and general automotive waste. the tests included proximate,ultimate and elemental analysis,tga,as well as calorific value determinations. in addition,the waste was tested in a desktop gasifier,and analysis was carried out to determine the presence and type of combustible gases. it was concluded that tyre waste and rubber/plastic waste are quite suitable fuels for gasification.
