Spent Catalyst Recycling
Market leading process technologies are the foundation of our value delivery for customers.
- Spent residue-upgrading catalyst is classified as a hazardous waste. It is leachable and contains sulphides, which are self-heating & pyrophoric (self-igniting), and reactive poly-nuclear aromatic hydrocarbons, benzene, arsenic oil, and metals
- Sending spent catalyst to landfill is expensive and there are fewer outlets as more countries block hazardous waste imports, particularly following the Basel convention which controls the transboundary movement of hazardous wastes to ensure it can be done in an environmentally sound manner
- Landfill can be a long-term liability. Valuable metals & opportunities to lower Greenhouse Gas (GHG) targets are lost
Leading Process Technology Delivers:
- Ferrovanadium for use in high strength low alloy (HSLA) steel enables a 20-40% reduction in steel use, significantly reducing resource use and transport-related CO2 emissions
- High purity V2O5 for Vanadium Redox Flow Batteries (VRFB) energy storage applications, enabling renewable power growth
- Approximately 80% lower CO2 emissions than primary extraction processing
- Renewable targets to achieve GHG goals
