Lab-scale characterization of emissions from incineration of halogen- and sulfur-containing nanowastes by use of a tubular furnace

Many solid materials contain nanoparticles to enhance their functionalities. The question of whether they may release at different moments life cycle is raised. Lifecycle includes waste management. There therefore a need determine the fate when are incorporated in incinerated. present study aims shedding light on these issues. In this context, three real-life wastes selected for specific compositions were combusted lab-scale furnace under incineration conditions. first two contained nanoparticles, namely silica and titanium dioxide. third was purposely nanoparticle free. addition, containing dioxide did chlorine nanoparticle-free material partly made sulfur. Disposal halogen sulfur-containing garbage implies an temperature 1100 °C. This complex composition seen as opportunity assess possible interactions between hazardous elements such sulfur during combustion. Most analyses supported by electronic microscopy imaging after having sampled particles fumes bottom ashes. Eventually, mechanistic scenarios drawn from experiments. Focus evolution nanostructure. It observed be preserved waste. disappeared both aerosol residue second material, though not initially nanostructured, led formation nanostructure aerosol.
