Ocean Sciences to Test Seaweed-Based Metal Recovery from E-Waste
Highlights
The announcement cites published laboratory research showing high selectivity and high-purity gold capture, although it does not present any results from Ocean Sciences’ own testing.
Ocean Sciences said it intends to seek intellectual property protection for the recovery material and associated processes.
The company said the programme is at an early research stage and will run for several months, with no laboratory results yet reported.

Ocean Sciences Ltd (ASX:OSS) OSS (ASX:OSS) , a company with seaweed sourcing and processing assets in Indonesia, announced in late October that its board has approved a research and development programme to test whether alginate from Sargassum, a brown seaweed, can recover precious metals and rare earth elements from retired data centre hardware and other electronic waste.
What the programme will test
Gold and silver are the initial focus, with rare earth recovery to be examined as a possible extension. The stated goal is a proprietary seaweed-based recovery solution for electronic waste recyclers and precious metal refiners. The company noted that data centre hardware is typically replaced on a cycle of several to several years.
The work is organised in several stages. The initial is extraction, in which alginate is prepared from Indonesian Sargassum. The next is capture, developing an alginate-based material that can selectively bind gold and silver, and potentially rare earths, from processed electronic waste solutions. The another is recovery, in which captured metals are released and recovered and, where technically feasible, the material is reused. The company said that, subject to laboratory success, it intends to explore pilot-scale testing and collaboration with commercial electronic waste processors.
Basis and existing assets
The announcement cites published laboratory research showing high selectivity and high-purity gold capture, although it does not present any results from Ocean Sciences’ own testing. It said potential reductions in energy and reagent use will be assessed as part of the programme.
The company pointed to its existing Indonesian seaweed sourcing network and the Seaweed Innovation and Application Centre in Takalar Regency, South Sulawesi, as assets it can draw on. It also said preliminary discussions are under way with Indonesia’s National Research and Innovation Agency (BRIN) about Sargassum alginate extraction. No agreement with BRIN is described.
Intellectual property
Ocean Sciences said it intends to seek intellectual property protection for the recovery material and associated processes. It proposes an initial patent application in Singapore, subject to intellectual property and patentability assessments. No application number or filing date was given.
Commercial aims and caveats
The stated objectives include targeting the data centre market, commercialisation and partnerships with data centre operators, electronic waste recyclers and metal refiners. No partners were named and no agreements were disclosed. Chairman Frank Cannavo linked the initiative to his mining background and described the technology as being at an early research stage. The company said progress will be reported as technical milestones are achieved, but it did not give milestone dates or pilot-scale timelines.
The announcement is explicit about the uncertainty. It says there is no assurance the technology will achieve the required technical performance, commercial scalability or economic viability, and that forward-looking statements depend on funding, laboratory progress, regulatory matters and securing partners or intellectual property protection.
What was not disclosed
The announcement included no laboratory data, revenue, cost estimates beyond the allocation, or financial forecasts. For readers, the practical position is that this is an approved, modestly funded research effort rather than a commercial product, and the next confirmed development is reporting against technical milestones whose timing has not been specified. The chairman is named as Frank Cannavo in the body of the release and Francesco Cannavo in the contact details, which the document does not reconcile.
