TUVALU has launched its first plastic waste and used engine oil pyrolysis machine, converting environmental pollution into alternative fuel through research led by the University of the South Pacific.

The technology, installed recently in Tuvalu, uses a heating process in the absence of oxygen to transform waste plastic and used oil into usable fuel. Each batch processes 10 kilograms of plastic waste to produce approximately 10 litres of liquid fuel and four cubic metres of hydrocarbon gas. Testing also showed that 15 litres of waste engine oil can yield around 12 litres of diesel-like fuel.

The resulting fuels have been successfully tested in generators, machinery, and household gas stoves, offering practical energy solutions for households and communities while strengthening local energy security.

The project was spearheaded by USP Master’s research student Miriama Uluiviti, an employee of the Tuvalu Waste Department, under the supervision of Associate Professor David Rohindra. Funding came from The Pacific Community (SPC) under the Pacific Adaptation of Waste to Energy Solutions (PAWES) Programme, with the machine supplied by Nufuels New Zealand.

“It is inspiring to see how our collective efforts can lead to such impactful change for our community,” Uluiviti said. “I am proud to be part of this pioneering initiative that not only addresses waste issues but also provides practical energy solutions for our families.”

Associate Professor Rohindra said the project, which began in 2024, demonstrated how dedicated students can turn innovative ideas into practical solutions.

Director of Waste and Recycling Epu Falega called the system a significant step forward for Tuvalu’s waste management and renewable energy strategies.

Speaking at the launch, Acting Secretary Walter Pulogo emphasised the importance of innovation and regional cooperation in addressing climate change, noting that Tuvalu’s leadership sets an example for other Pacific nations.

The project delivers environmental benefits by reducing plastic and waste oil pollution while supporting climate resilience through sustainable waste utilisation.
