Patent strengthens Sparc's position in its environment and sustainability portfolio

Sparc Technologies Limited ( ASX: SPN ) ( Sparc or the Company ) is pleased to announce it has received confirmation that the United States ( USA ) patent application number 15/578149 has now been issued as a patent.

Pollution of water and air by certain ionic contaminants, including heavy metals, has long been and continues to be a serious environmental concern for modern day society. This new granted patent now grants Sparc exclusive access to graphene’s unique ability to act in a porous matrix to remove heavy metal ions from liquid or gas, which has demonstrated high performance and efficiency for such use.

The Company is now also exploring ways in which this technology can be tailored to facilitate removal of additional organic species from liquids or gas to further strengthen its ability to have a substantial impact on the many environmental challenges that exist today and complements the significant work the Company has already undertaken in respect of PFAS remediation.

As an additional technology, pursuant to Sparc’s Sustainability & Remediation - Extraction core division, Sparc is delighted that the Company’s new patent has been granted in the USA, which will allow the Company to move more rapidly into commercial deployments.

Sparc Managing CEO, Mike Bartels, commented:

“The granting of this patent further enhances Sparc's technology portfolio in the area of sustainability and waste remediation whilst complimenting the work being undertaken with PFAS. The versatile class of graphene-based materials covered under this patent presents an opportunity to develop solutions for a wide range of high-impact environmental contaminants, such as mercury and arsenic. Intellectual property (IP) goes to the heart of Sparc's value creation and Sparc is currently in discussions with commercial partners to further develop the technology under this patent.”

The official patent number is 10864498. The patent is licenced from the University of Adelaide ( UoA ) and will not incur licensing fees nor a royalty due to UoA being a substantial shareholder in Sparc Technologies.
