A study on the combustion of EVA waste with high sulphur coal was carried out in a fluidised bed EVA is used in the production of shoe soles and beach sandals and its waste is currently being disposed of by landfilling. Work was done to study the capability of this material to capture sulphur from coal as it contains 40% calcium. The results show that co-firing coal with EVA waste can result in a significant reduction of SO2 emission. The reduction in SO2 emission can be attributed primarily to the decreased sulphur content in the feed mixture and the increased amount of Ca in ash as EVA waste increased and acting as sorbents for sulphur capture. These results also indicate that co-firing of EVA waste with coal reduced SO2 emissions beyond what might have been expected as simply a result of dilution alone. This work demonstrates that, in certain case, co-combustion can be used to reduce the need for land based waste disposal with the reduction of SO2 emission as an added advantage.
