Parkway Minerals: New environmental technology promises profitable purification of liquid mining waste streams

How does a good idea for the environment become a business? This can be observed in the Australian company Parkway Minerals (ASX: PWN; FRA: 4IP), which is systematically working on the commercialization of its sustainable technology portfolio, for the recovery of valuable materials from liquid waste streams, in mining. In simple terms, the technology is a further development of seawater desalination related technologies, but more sophisticated. Although pure water is a desirable by-product produced through Parkway’s key processing technology, the main goal is to recover the valuable salts or other valuable substances contained in concentrated waste brine or other feedstock. Parkway's value proposition for large mining companies essentially consists of: You can improve the efficiency of your operations and reduce costs, whilst also reducing waste and protecting the environment.

For more than a decade, research activities were performed in cooperation with university researchers. In late 2019, through an M&A transaction, the technology migrated to the listed Parkway Minerals, which has since reinvented itself under the recently appointed Managing Director, Bahay Ozcakmak. Within a short period after the M&A transaction, Parkway has partnered with internationally renowned engineering services provider Worley. Worley put Parkway's technology through its paces, most recently in a prefeasibility study. The partnership is based on a global strategic cooperation agreement. The recent pre-feasibility study for the Karinga Lakes potash project, provided additional validation of the benefits of the technology. The data from this study is now supporting case studies with potential customers, who in turn are now evaluating whether to engage Parkway and Worley to perform a feasibility study for the project in question. Parkway's recent addition of its own pilot plant, which is capable of processing liquid waste streams on a larger scale, is particularly helpful in the future evaluation of projects. Customers can see under realistic conditions whether and how the process works with their specific problem waste.
