Sectors
Steel Wastes
BF & BOF Dust & Sludge, EAF Dust, Iron Ore Fines, Coke Breeze, Coke Fines, Mill Scale, Scrap Fines & Turnings, Ladle Fines...
By-products from ironmaking and steelmaking operations that contain ferrous and/or carbonaceous content, suitable for recycling into the production loop. These materials are often underutilized due to variability, fine particle size, or contamination but can be transformed into high-value feedstock through cold agglomeration.
How can Cold Agglomeration benefit your business?
- Uniform pellet shape and consistent quality, enabling easier handling and process integration.
- Superior mechanical strength with enhanced binder interaction—boosting CCS, Tumble, and RDI performance.
- Increased durability during transport, storage, and furnace charging.
- Lower energy consumption compared to sintering, with no need for high-temperature curing.
- Reduced emissions and landfill diversion, improving waste valorization and ESG performance.
- Supports circularity goals by reintegrating metallurgical waste into the value chain.
Primary Ores
Concentrates and Direct Shipping Ores from various origins
Iron Ore (Magnetite, Hematite, Goethite...), Manganese Ore, Magnesium Ore, Chrome Ore, Nickel Ore, Pyrite, Spodumene, Bauxite, Quicklime, Slaked Lime...
Ores that are typically processed into pellets or sinter but can be agglomerated cold to reduce emissions, cut capital and operating costs, and enable decentralized processing near the mine or user.
How can Cold Agglomeration benefit your business?
- Comparable performance to indurated pellets in terms of strength and reducibility, without the sintering step.
- Compatible with ore blends, fluxes, and reductants, allowing recipe flexibility and feedstock optimization.
- >80% GHG reduction vs. conventional pelletizing routes, aligning with carbon neutrality targets.
- Greater density and strength, ensuring optimal furnace performance and reduced degradation.
- Lower CAPEX and OPEX due to ambient temperature processing and simplified equipment setup.
- Supports decentralization of agglomeration, ideal for remote or modular mining operations.
Mineral Coals
Coking Coal, Petroleum Coke, Anthracite, Bituminous Coal, Subbituminous Coal, Lignite, Peat...
Fine coal by-products from beneficiation plants, crushing, or storage systems, often discarded or sold at discounted prices. These carbonaceous materials retain high calorific value but suffer from poor flowability and dust generation. Agglomeration unlocks their use in energy-intensive industries with tailored combustion properties.
How can Cold Agglomeration benefit your business?
- Improved fuel performance through enhanced calorific value and combustion uniformity.
- Dust suppression and improved flowability, reducing handling hazards and losses.
- Customizable blends to meet specific energy or metallurgical profiles.
- Potential cost savings by upgrading low-value fines into usable feedstock.
- Facilitates cleaner coal use with reduced particulate emissions and better furnace control.
Biochar & Biocarbon (Biogenic Coals)
Torrefied Biomass, Charcoal, Carbonized Organic Waste...
Biogenic carbon materials derived from forestry, agriculture, or sewage sludge, either raw or thermochemically treated (e.g., torrefied or pyrolyzed). These residues are increasingly sought as carbon-neutral reductants or fuels but require densification and stabilization to match industrial handling and combustion standards.
How can Cold Agglomeration benefit your business?
- Enables use of biogenic waste streams (e.g. biomass) for sustainable heat and reductant applications.
- Reduces spontaneous combustion risks, enhancing storage safety.
- Production of high-quality pellets with uniform density, calorific content, and moisture control.
- Supports circular bioeconomy, substituting fossil carbon in metallurgical and thermal processes.
- Carbon-negative potential, improving overall emissions balance and creating green branding opportunities.
Other Wastes
Mine Tailings, Red Mud, Fly Ash, Black Mass, Slag, Construction Debris, Rubble...
Industrial by-products and mineral residues not traditionally reused in metallurgical processes due to high gangue content, poor physical properties, high moisture, or environmental risk. These include tailings, red mud, fly ash, and other chemically complex wastes, which can be transformed into stable, valuable products through agglomeration and conditioning.
How can Cold Agglomeration benefit your business?
- Converts liabilities into value-added products, contributing to zero-waste objectives.
- Improved handling and transport through dust-free, shaped agglomerates.
- Stabilization and immobilization of harmful components, reducing leachability and environmental risk.
- Enables reuse in construction, cement, or filler markets, opening new revenue streams with the introduction of new building materials and co-products.
- Supports site rehabilitation and CSR initiatives, especially for legacy waste management.
