The partnership has developed a natural and sustainable solution for the treatment and use of CSG water.

According to the companies, the four major Queensland CSG companies could generate the extra $61 million in annual profits by adopting the technology instead of the $36 million recurring payment for traditional osmosis water purification.

Based on a 30-year mine life it means an extra $2.9 billion in profits compared to $1.1 billion in costs.

Under the agreement CSG Enviro will use PGX’s technology as part of its solution for environmental remediation, engineering and project development.

CSG Enviro Services chief executive officer Lee Fergusson said the system could mitigate a serious problem in the industry.

“It is an environmentally friendly and sustainable way to meet legislative requirements for CSG and underground coal gasification extraction processes,” he said.

PGX’s bioremediation system uses salt-tolerant plants to treat salt brines and extract clean water for agricultural use.

The system takes about six to 12 months to reach full production.
