Once the gasification process has taken place, in addition to the synthesis gas, we obtain ash in an amount equal to 5-10% of the treated original matrix (approximately 20% from sludges).
Based on the analyzes that will be conduct over them even several times a day, the ashes will be destined as:
- soil fertilizer;
- beach nourishment material;
- sand for construction;
- a soil improver - binder for compost
If the analyzes show that the ash is not inert, therefore harmful to the environment, the single lot analyzed will be sent to a landfill or to a plasma torch where it will be transformed into a plasmable vitrified lava material and therefore totally free from environmental risks.
Our gasifiers are normally equipped with plasma electrodes at the tail which allow the vitrification of the ash, the cracking of the TARs and the purification of the syngas with minimal consumption in terms of electricity.
The higher the temperature inside the gasifier, the lower the risk of incurring in non-inerted lot.
Atmospheric emissions do not occur due the application of our systems.
