Built for Low-Impact Recycling
Cleaner, Safer, Circular Future
SPT Recycling’s roasting-free, solvent-free short-process technology is engineered to dramatically reduce environmental impact.
Our systems operate with minimal air emissions, no wastewater, and full electrolyte recovery, ensuring the highest level of environmental compliance.
We design every line to meet – and exceed – global sustainability standards.
Air Emissions
Dry Low-Temperature Dismantling
Condensed Gas (Electrolyte Recovery):
VOCs and fluorides captured and treated through deep purification.
Emission levels:
• Volume: 150 Nm³/h
• NMHC: <25 g/m³
• HF: <2.5 mg/m³
Sorting Gas (Airflow Separation):
Particulates from mechanical sorting filtered through bag filtration.
Emission levels:
• Volume: 36,000 Nm³/h
• Particulates: <10 mg/m³
• Ni & Co compounds: <5 mg/m³
All emissions meet EU industrial discharge standards.
Solvent-Free Wet Recycling Technology
High-purity metal and lithium recovery with ultra-low emissions.
- No significant gas generation during extraction of Ni, Co, Mn.
- Minor acidic vapors absorbed and reused inside the system.
- Fully compliant with atmospheric emission standards.
Water Emissions
Zero Wastewater Discharge for Dry Dismantling
The dry dismantling process uses no water at any stage, eliminating wastewater generation entirely.
- No process water
- No chemical rinsing
- No liquid effluent
- Recovered electrolyte is recycled for reuse
This ensures the system operates with zero water pollution and minimal environmental impact.
Minimal Wastewater Discharge for Wet Recycling
Evaporative condensate and washing water are recirculated within the
production process. Only small amounts from cleaning and lab testing.
Total discharge: ~1 m³/day, treated to meet discharge standards.
Solid Waste Handling & Resource Recovery
Dry Process Solid Waste
- Metals (Steel, Copper, Aluminum):
Recovered as clean fractions and returned to the industrial supply chain.
- Separator & Plastic Residue:
~500 tons/year generated; classified as general industrial waste and transported to licensed disposal facilities.
- Electrolyte Residue:
Fully captured and purified; no discharge.
Wet Process Solid Waste
- Graphite Residue:
~3,136 tons/year produced after metal extraction.
Considered general solid waste but can be sold as recycled graphite for industry use.
- Iron–Aluminum Sludge:
~320 tons/year generated during leachate purification.
Collected and safely transported to qualified treatment facilities.
