Buy and sell ashes & slags
Ashes and slags are generated in a wide range of industrial processes, including energy production, waste treatment, metal production and manufacturing. Depending on their origin, composition and processing, these residual materials can often be recovered, recycled or reused in new applications.
APT connects companies that offer ashes and slags with businesses looking for suitable secondary raw materials.
Find ashes and slags for your application
Looking for ash, slag or other mineral residual streams? Browse available listings and compare materials based on specifications, quantities, availability and location.
Different processes produce materials with very different characteristics. Relevant properties can include:
- Chemical and mineral composition
- Particle size and granulation
- Moisture content
- Metal content
- Processing or treatment status
- Available quantity
- One-off or recurring availability
Detailed specifications help buyers determine whether a material is suitable for their production process or application.
Sell your ash and slag streams
Industrial ashes and slags do not always have to be treated solely as waste. Depending on their properties and applicable regulations, these materials may have value as secondary raw materials.
Companies can use APT to offer both one-off batches and recurring residual streams. Providing information about the material’s origin, composition, processing and available quantities helps potential buyers quickly assess its suitability.
Applications for ashes and slags
After suitable processing and quality assessment, ashes and slags can potentially be used in applications such as:
- Cement and concrete production
- Road construction
- Construction materials
- Aggregates and fillers
- Metal recovery
- Mineral recovery
- Infrastructure projects
- Other industrial production processes
The possible application depends on the exact material properties, quality requirements and applicable environmental regulations.
From residual stream to secondary raw material
Reusing ashes and slags can reduce demand for virgin mineral resources while creating new value from existing industrial material streams.
By bringing suppliers, processors and buyers together, APT helps companies identify new destinations for residual materials and develop more circular supply chains.
