Technology Platform
Salpro - Selective Mineral Recovery from Saline Waters
Salpro is a platform technology for the selective or sequential recovery of commercial-grade mineral products from inorganic saline waters using combinations of chemical reaction, evaporation, and separation steps. First licensed in 2001, Salpro has undergone several rounds of enhancement for broader applicability and has been independently evaluated and benchmarked as one of the most
sustainable ZLD (Zero Liquid Discharge) technologies for managing
saline industrial wastewater and desalination brines.
Key advantages of Salpro:
-
Flexible system design and modular scalability
-
Demonstrated technical, economic, and environmental viability
-
Conversion of large saline volumes into low-footprint mineral products
-
Use of recovered materials as high-grade feedstock or direct-use commodities
Commercially deployed, Salpro is applicable across multiple sectors including but not limited to direct lithium extraction from brine fields, desalination, energy generation, and mining.
MBC - Mineral-Based Composites for Encapsulation
MBC is a novel composite mineral technology designed for
the safe containment of hard-to-abate residuals, including
PFAS-laden waste, saline industrial residues, and toxic metals.
The technology solidifies waste streams within mineral
matrices via aggregation and/or granulation steps,
producing form-stable, non-leachable solids suitable for safe
landfilling.
Key attributes of MBC:
-
Adaptable to solid, slurry, or liquid waste streams
-
Suitable for both point-source and legacy contamination
-
Enables long-term immobilisation of persistent contaminants
-
Applicable in industrial, environmental, and infrastructure settings
MBC was recognised as a Top Invention at the 2023 World Economic Forum, reinforcing Pact Renewables’ role as a leading technology company.
Synpotash - Production of Variable-Solubility SOP Fertilisers and Derivatives
Synpotash is a proprietary mineral conversion technology that
produces chloride-free, variable-solubility sulphate of potash (SOP)
fertilisers and derivatives from potassium-containing brines and
rocks. It is designed for flexibility, high product purity, and compatibility with CO₂ capture and clean energy applications.
Applications and outcomes:
-
Variable solubility SOP fertiliser products for high-value crops
-
Downstream production of K-based additives for CO₂ capture
-
Alkaline fuel cell and long-duration battery precursors
-
Critical material recovery from non-traditional sources
The technology complements Salpro by converting potassium-rich brines into strategic and value-added products.
Synergistic Deployment
Through an integrated platform approach, Salpro recovers saleable mineral products and reduces saline wastewater volumes; MBC secures and immobilises hazardous residuals; and Synpotash generates value-added fertilisers and strategic materials from potassium-bearing brines and rocks.
The outcome: a practical, science-based pathway to zero or near-zero waste discharge (ZWD) - helping reduce project footprint, enable regulatory compliance, secure community approval, and build investor confidence.
