Sedna International

Sedna Limited is a Hong Kong-domiciled investment and holding company pioneering scalable, tech-driven solutions to Africa's intertwined challenges of plastic waste pollution and energy insecurity. Our core innovation: modular pyrolysis plants that thermally decompose non-recyclable plastics into valuable outputs like diesel-equivalent fuel, syngas for electricity, and char—diverting waste from landfills and oceans while producing clean, local energy.

Founded on principles of commercial viability and measurable impact, Sedna leverages proven continuous-feed pyrolysis technology from strategic Chinese partner Shangqiu Aotewei, who also holds equity. Our Hong Kong structure provides offshore security and USD-denominated returns for investors, with South African operating entities (Sedna WC and Sedna GP) ensuring local compliance and execution.

The Big River Plastic to Energy project kicks off with our flagship 4-reactor plant in Atlantis Special Economic Zone, fully funded and under development, processing 30-40 tonnes of waste daily. We plan to scale to five sites across South Africa (expanding to 8 reactors each), with a total value of USD25 million—seeking USD20 million for the remaining four sites. Outputs include low-sulphur fuel (off-take LOI with Nestlé), grid-exportable power, and carbon credits, projecting >25% IRR at full scale.

Through partnerships like our MOU with IUCN IslandPlas for regulatory support and waste collection, and local equity participation for community engagement, Sedna advances UN Sustainable Development Goals (7: Clean Energy, 11: Sustainable Cities, 12: Responsible Consumption, 13: Climate Action). We create jobs (~50 direct per site), reduce emissions (tens of thousands of CO2e avoided annually), and promote circular economies.

Sedna invites Belt and Road-aligned investors, EPCs, and manufacturers to collaborate on this replicable model, extending to islands like Mauritius and Seychelles for broader African impact.
