Water Purification and Soil Remediation

Global Patent PendingPCT/AU2016/05041– Water Purification and Soil Remediation -water purification, oil removal from water, soil remediation

1. Research Gate, Yang et al.2. Sector Study on Environmental Services: Environmental Damage Remediation Services, Oct 2017

Proven application of water and soil remediation to be utilised at environmentally contaminated sites

SPN has identified how graphene can contribute to PFAS clean up and is undergoing proof of concept test work to prove up the application for:

Containment of PFAS using graphene

Destruction of PFAS using graphene is potentially transformational

Pollution Remediation

The potential applications of graphene in pollution remediation are adsorption, membrane separation, catalysis and environmental analysis

The adsorption efficiency of graphene adsorbents largely depends on its surface area, porous structure, oxygen-containing groups and other functional groups, adsorption conditions, and also the properties of adsorbates1

SPN has identified potential applications of water purification and soil remediation

Australia alone has an estimated 160,000 contaminated sites with as many as 75,000 different contaminants2

Metals in Tailings

Estimated US$1 trillion worth of precious metals sitting in mine tailings1

Estimates that there is approximately US$1T worth of precious metals already extracted from the ground, sitting at old mining sites globally1

Opportunity to work with local mining industry

Initial Focus on Precious and Base Metals

Graphene and Soil Remediation

Graphene can be utilised to separate specific metals from tailings dams and waste ore on mine sites

UA has existing IP on 3D graphene composites that enable SPN to target the removal of precious metals

SPN to work with partners in the mining industry to develop optimum solutions

Added environmental benefits of removal of metals from soils on local waterways
