Technology Platform

Salpro is an enabling technology platform for selective recovery of commercial-grade mineral products from inorganic saline streams by a combination of chemical reaction, evaporation, and separation process steps, using conventional mineral processing equipment. The technology is highly scalable and capable of achieving zero or near zero liquid discharge outcomes, by converting the bulk of impactful waste into low carbon footprint commercial-grade mineral products which may be used as a feedstock for production of value-added downstream products.

Salpro technology was first piloted and publicly demonstrated for the recovery of high-purity magnesium metal feedstock from seawater-sourced cooling effluents of Port Augusta coal power station in South Australia, and in 2006 selected by the US Bureau of Reclamation as then the best-fit zero liquid discharge (ZLD) brine management solution. The technology has since been fine tuned and successfully demonstrated for recovery of high-value mineral products from a wide range of saline effluent streams, including but not limit to waste waters generated by desalination plants, salt harvesting operations, oil/gas production, energy generation plants, food and fibre production, mining and mineral processing, as well as leachates from washing of fly ash generated by coal power stations and waste-to-energy plants. 

Synpotash is a sustainable technology, which produces high-value, variable solubility potash fertilisers, as well as potassium containing compounds for alkaline-based fuel cell batteries from a wide range of feedstock materials including minerals and volcanic rocks and effluents generated in mining/mineral processing operations, solar potash production, fertiliser production, and waste-to-energy generation plants, to name a few. The treatment process is based on a proprietary mineral conversion scheme and uses conventional mineral processing equipment. A commercial production facility using this technology for recovery of potassium fertilisers from water leachates of fly ash generated by waste-to-energy plants, was recently commissioned in Sweden.

MBC Composites is a breakthrough technology for producing plastic/polymer free fast-setting mineral formulations from cheap and plentiful precursor minerals for application as highly functional feedstock materials for manufacture of diverse industrial and environmental products. Example product application areas include soil degradable seedling pots and planter sleeves, soil conditioners for forestation, agroforestry, crop production and urban greening, as well as media for aggregation and granulation of hard to abate waste streams, as an effective processes for encapsulation of intractable solid, slurry and liquid wastes before safe landfilling. Another growing application area and an area of our current R&D focus is the use of technology as a highly effective and practical tool for removal of CO2 directly from air for farm-scale applications. The carbonated minerals may in turn beneficially used as nutritious soil conditioners or as highly desirable low-cost feedstock materials for downstream manufacture of low footprint industrial products. Yet another application of MBC composites with measurable positive environmental and social impacts relates to cost-effective reduction of GHG emissions from substrates, such as landfills and manure stockpiles in cattle farms and poultries, as well as anaerobic digestion systems.

Integrated Treatment Systems

Depending on the composition of a saline waste

water, as diagrammatically shown in the opposite,

our technologies may be integrated in a single

delivery system to provide an end-to-end

solution for the clients seeking a combination

of resource recovery and safe disposal of

intractable and toxic waste residuals for

achieving Zero Liquid Discharge (ZLD) or

near ZLD outcomes. 

 

To our knowledge, Pact Renewables’ technology platform is currently the only proven platform recognised for offering ZLD and ZWD solutions to a number of industries seeking sustainable and cost-effective saline waste management solutions.
