Do You Know the Value of Incinerator Bottom Ash?
What is Incinerator Bottom Ash (IBA)?
☆Incinerator bottom ash (IBA) is a byproduct generated during waste-to-energy (EfW) plant operations. It contains valuable metals (including gold, silver, copper, and iron) alongside non-metallic components, making it a recyclable resource rather than mere waste.
Key Composition & Properties of IBA
▷ Metal Content:
Precious metals (gold, silver) and base metals (ferrous/non-ferrous) are highly sought-after raw materials for smelters, with established global trading supply chains.
▷Physical Characteristics:
Classified as solid waste, IBA has a particle size mostly below 10 mm, dominated by fine particles.
▷Main Components: Slag, glass, ceramics, bricks, stones, plastics, metallic substances, and incompletely combusted organic materials (paper, fibers, wood).
Why IBA Separation Is Critical
EfW plants produce approximately 0.23 tons of IBA per ton of domestic waste incinerated. Effective separation is essential before comprehensive utilization, as it unlocks the full value of this byproduct while reducing environmental impact.
Value & Applications of Processed IBA
1. Metal Recovery
Pretreatment separates and recovers ferrous metals, non-ferrous metals, precious metals, and heavy metals, which can be directly sold to metal recyclers for reuse.
2. Construction & Infrastructure Use
After optimization, unburned residual waste is processed into sand and gravel aggregates, serving as:
- Pavement materials
- Cement/concrete substitute materials
- Landfill cover materials
RUIJIE Process Characteristics
1.No Air Pollution
Measures such as water-injection crushing and sealed crushing are adopted to prevent dust from escaping, resulting in zero air pollutant emissions.
2.No Waste Water Pollution
Through 100% recycling via the water recycling system, the goal of zero sewage discharge is achieved.
3.No Noise Pollution
Equipment featuring low noise and low vibration ensures that noise emissions from all types of equipment meet the limit standards during operation.
4.100% Utilization
Separated metals are recycled, while slag is used to produce unburned brick products, enabling 100% comprehensive utilization.
Incineration Bottom Ash (IBA) Sorting Equipment Core Technology
01.Slag Treatment Process: It achieves high recovery rates of scrap metal and clean production of environmentally friendly sand. The resulting sand contains minimal metal, glass, mud, and other impurities, and the entire production process is mechanically automated. The new production line features advantages such as dust prevention, noise reduction, and sewage circulation, filtration, and reuse.
02.Crushing Series Products: New simplified maintenance methods and waterproof treatments have been added. Compared to traditional equipment, they are more stable, with finer output and larger processing capacity.
03.Jig Series Products:The cam transmission mechanism has been optimized. Compared to traditional equipment, they offer a higher metal recovery rate, greater energy efficiency, and enhanced durability.
04.Magnetic Separation Series Products: High-remanence, high-coercivity rare earth NdFeB magnetic blocks are used as the bottom magnetic source, featuring a low demagnetization rate and high separation purity.
05.Screening Series Products: Compared to traditional screening equipment, they have larger processing capacity, higher efficiency, and higher screening accuracy. Additionally, they operate in a fully enclosed manner to prevent dust emission.
RUIJIEZHUANGBEI Process Flow
Our company mainly reprocesses slag from waste incineration power plants using physical separation technologies, including
- particle size screening
- magnetic separation
- buoyancy separation
- eddy current separation
Through these processes, we separate out iron, aluminum, and small amounts of non-magnetic metals (such as copper), while simultaneously obtaining construction sand (coarse, medium, and fine grades).
The sorted metal materials are sold to recycling units for reuse, and the coarse, medium, and fine sand materials are utilized in brick-making or by building material production plants for reprocessing.
The specific production process flow and pollution generation process diagram are shown in the figure:
1.The preparation of environmentally friendly building materials
Environmental protection bricks (including unburned bricks, colored road bricks, and thermal insulation materials) use slag as the main raw material. The slag undergoes pretreatment (weathering and metal removal) before being mixed with materials such as cement, curing agents, activators (or pigments) in specific proportions, followed by press forming.
This process does not involve calcination or autoclaving. Its early strength is mainly developed through the pressure of the forming machine, while its later strength is primarily derived from cement bonding and the activation of slag activity. It is a mature process.
2.All Kinds of Precious Metals can be Recovered

1.The Cost of Incineration Bottom Ash(IBA) Disposal
The incineration bottom ash treatment process requires capital investment, including equipment costs, labor costs, and post-treatment waste disposal costs. While this investment may be prohibitive for some producers, treating slag is worthwhile in the long run.
This is because the recovered profits can often cover these costs and even generate substantial returns for the business.
2.Profit From Incineration Bottom Ash(IBA) Disposal
The profitability of incineration bottom ash treatment depends on the recyclable proportion of residues and the market prices of these recyclables. For instance, non-ferrous metals like copper and aluminum can be recycled to create economic value.
Additionally, slag can be reused as a raw material in building material production to generate further returns. In general, for steel mills or similar enterprises that need to dispose of slag, while investing in treatment facilities may involve high initial costs, slag disposal is often highly profitable in the long term.
