Bottom ash discharged in a dry state can be handled in the same way as dry bulk material. The free-flowing nature of dry bottom ash ensures that it can be processed in a fully automated industrial plant, thereby guaranteeing a high and consistent quality of the metallic and mineral products separated from the bottom ash. 

The absence of water offers the following advantages:

• No water consumption
• 15–25 per cent less bottom ash volume
• The bottom ash has a constant moisture content of less than 0.1 per cent.
• No additional physical mixing of mineral and metallic fractions
• Can be fractionated industrially (to any degree of fineness)
• Particle size distribution: In dry bottom ash, all substances and particles retain their original form. There are no limits to the customisation of the bottom ash according to size, weight, colour, conductivity, etc.
• Negligible corrosion of the metals in the bottom ash
• No H₂ formation
• No corrosion in the discharge mechanism/immediate surroundings or in the processing plant (long depreciation period)
• No ammonia formation in the plant
• Bottom ash can be processed directly from the discharge point without intermediate storage.
• Bottom ash can be stored for any length of time without adverse effects on the recovery of valuable materials (corrosion, caking).
• Due to the nature of the process, dry-discharged bottom ash is generally well-burnt out and therefore has a low organic content (TOC), which does not place an unnecessary burden on processing and mineral content and also results in lower emissions in terms of the recovery of metals and minerals.
• Preservation of setting ability: The water in wet deslagging triggers the setting reactions in the slag as soon as it is discharged. With dry slag, these reactions can be triggered at a later, desired point in time.
