In order to ensure appropriate treatment of the wastes used as fuel and/or raw materials in the kiln, BAT is to use the following techniques:
| Technique | |
|---|---|
| a | Use appropriate points to feed the waste into the kiln in terms of temperature and residence time depending on kiln design and kiln operation |
| b | To feed waste materials containing organic components that can be volatilised before the calcining zone into the adequately high temperature zones of the kiln system |
| c | To operate in such a way that the gas resulting from the co-incineration of waste is raised in a controlled and homogeneous fashion, even under the most unfavourable conditions, to a temperature of 850 °C for 2 seconds |
| d | To raise the temperature to 1 100 °C, if hazardous waste with a content of more than 1 % of halogenated organic substances, expressed as chlorine, are co-incinerated |
| e | To feed wastes continuously and constantly |
| f | Delay or stop co-incinerating waste for operations such as start-ups and/or shutdowns when appropriate temperatures and residence times cannot be reached, as noted in a) to d) above |
