Waste elimination

What are the ways of elimination?

The sectors of elimination (recycling, compost, treatment of special waste and incineration) apply in:

  • waste of production of the industries manufacturer of nanoparticles or those using nanoparticles, as raw material (industry of the painting, the cosmetics, pharmaceutical, electronic,…),
  • waste of research laboratories,
  • household waste.

The NanoFlueGas project, launched in 2011, deals with end-of-life material safety, in particular the incineration sector.

Incineration process.

Before entering the incinerator, the waste has to be homogenize. They are then introduced continuously into an oven warmed between 800°C and 1000°C. Incinerators with fluidized bed, with rotary oven allow the incineration of industrial waste. The incinerator with fluidized bed is the most used. The combustion in fluidized bed is a technique realized on some coal or on certain homogeneous waste (muds of water-treatment plant). In this reactor the combustion is made in a bed of sluggish materials put in suspension by injection of warm air (vertical, horizontal, on the base or in walls of the oven). The regulation of the flow of air, it is possible to decrease the quantity of smoke and the costs of treatment.
