Ryowa takes over Phosphate Hill fertilizer complex

Ryowa II GPS Pty Ltd, a Queensland-based investment company and wholly owned subsidiary of Mayfair Australia Corporation, has taken over Dyno Nobel’s Phosphate Hill fertilizer complex in North-West Queensland, positioning itself as the new long-term owner of one of Australia’s major DAP/MAP production sites. Ryowa II GPS forms part of Mitsubishi Corporation’s Australian group companies, supplying electricity to Boyne Smelters and other power users, which places the new owner firmly within a long-established Japanese trading house presence in Australian heavy industry.

Under the deal, Ryowa has bought Phosphate Hill as a going concern, taking on the economic risk and benefit of the operation and assuming all operational and environmental liabilities. This means the acquisition is about operating and sustaining the complex rather than closing it or stripping assets. Phosphate Hill is a critical domestic source of DAP and MAP for Australian farmers and a key outlet for sulphuric acid and gas from Glencore’s Mt Isa smelter, tying Ryowa’s investment into both fertilizer production and regional industrial supply chains.
