Pacific Adventist University Students Work Towards a Brighter, Greener Future

A recent environmental study is aimed at finding innovative pathways for the recycling of agricultural waste products such as banana fiber.

Pacific Adventist University is at the forefront of groundbreaking research that could bring significant environmental benefits to Papua New Guinea (PNG).

Several studies are underway at the Port Moresby campus. One is aimed at finding innovative pathways for the recycling of agricultural waste products such as banana fiber. The university farm, with its extensive plantation of more than 40,000 bananas, is ideally suited for the study.

The study is looking at how banana fiber can be used for sustainable natural products that could replace plastics and agricultural chemical fertilizers. With banana farming widespread across PNG, the ability to operate activities with zero environmental impact would be significant—a first for the Pacific.

A second study is investigating the most suitable recipe for converting used vegetable oil into a quality biodiesel that is anticipated to be equivalent to the international standard.

“This is a research and development project. The findings of this study will be used to contribute to biofuel policies development in Papua New Guinea, as well as promoting the reduction of environmental pollution in terms of used cooking oil, which is currently an environmental hazard in PNG,” said Linta Qalopui, lecturer in PAU’s School of Science and Technology.

By recycling and converting the cooking oil into biodiesel, it can be used in diesel engines, cutting CO2 emissions by about 41 percent compared to fossil diesel fuel. “This also provides an alternative and environmentally friendly fuel for Papua New Guinea going forward,” said Qalopui.

In early trials, the biodiesel produced from the research was used to fuel five diesel motor vehicles without any engine modification and with trouble-free operation. The next stage of the study will assess how the converted oil affects engine performance in generators, water pumps, and many other diesel vehicles.

The research is now attracting global attention. Qalopui has been invited to present at the fourth International Conference on Biofuel and Bioenergy in London, England, in October 2023.

Other environmental studies currently underway at PAU are looking at the impact on the environment of the expanding palm oil industry in Kairak, East New Britain Province, as well as the hunting pressures on mammals in savannas and woodland forests in Southern Papua.

Dr. Carol Tasker, PAU head of Research and Postgraduate Studies, said students and their supervisors are involved in around 20 research studies relating to environmental, health, education, family, and other current issues.

“Recently, PAU has also been asked to conduct research on membership retention in PNG, and on literacy levels and possible impact on church ministry,” Dr. Tasker said. “We are excited about our research vision—‘Exploring Resources, Expanding Horizons, Inspiring Hope’—reminding us of infinite possibilities for learning more that can positively impact churches, families, and communities across the Pacific.”
