Safer disposal of salt water for CSG companies

Queensland-based biotechnology company PolyGenomX (PGX) has entered into a technology collaboration agreement with CSG Enviro Services that will expand its uniquely sustainable solution for the treatment and use of coal-seam gas water (CSGW).

PGX technology is a wholly natural, highly effective system for remediating the CSG industry’s process water. The PGX system also creates electricity producing biomass valued at twice the cost of running an RO treatment plant’s energy needs.

The agreement with CSG Enviro will lead to an initial bioengineered brine management system expected to be in operation this year.

The long term application of the agreement and use of PGX’s bioremediation system is expected to provide safer and sustainable CSG operations without adding major costs. The PolyX™ process enhances plants to grow faster, more robustly and increase yields. It does not involve the creation of GMO’s.

Peter Rowe, managing director of PolyGenomX, said the management and disposal of salt-rich brines generated from CSG and underground coal gasification extraction processes was a critical issue in the debate over industry safeguards.

“Adopting natural and sustainable solutions to remediate CSG water contamination could have a significant impact on the future of the industry and help assuage public health concerns,” he said.

PGX provides a bioremediation system that uses highly salt-tolerant epigenetically adapted plants to treat CSG production water and salt brines produced by reverse osmosis and other salt-extraction processes. The salt-consuming plants can be grown for biofuels and the trees can be grown for timber, with no salt contamination of the environment.

Dr Lee Fergusson, CEO of CSG Enviro Services, said, “We see the remarkable research and technology of PGX as being a perfect supplement to our already considerable knowledge base in salt water and brine management.”
