This sub-conference is to discuss the pyrolysis technology applications in disposal of organic solid wastes, such as industrial solid wastes and municipal solid wastes and others. This sub-conference is also aim to explore the research progress, applied situation, existing problems and solutions in applying pyrolysis process, design of pyrolysis reactors, high-value products and catalysts. It also aims to develop the advantages relevant to pyrolytic process that can avoid extensive crushing, coking in furnace, blockage and avoid generating secondary pollutants such as incineration fly ash and dioxins.
