In Papua New Guinea, on Karkar Island, coconut trees are being utilized for a purpose beyond their traditional export value. The white flesh of the coconut, known as copra, is processed into oil, which is then transformed into biodiesel. This renewable energy source is powering essential services on the island. The Kulili plantation, encompassing approximately 980 hectares, is central to this initiative, producing 600,000 liters of coconut-based biofuel annually.
The biodiesel project started in 2007 at Kulili with the aim of creating a sustainable fuel alternative. The operation has expanded over the years, with the managing director, Derek Middleton, seeking further investment to increase production. The fuel is utilized across Karkar for a variety of purposes, demonstrating a shift towards renewable energy sources within the local community.
Similar projects are underway in other Pacific nations, such as Vanuatu and Fiji, with research focused on the broader application of coconut biodiesel. The PNG University of Technology (Unitech) is examining its potential use throughout Madang province, aiming to reduce reliance on imported fuels. Despite the challenges in securing financial backing for expansion, the project's social and economic benefits are highlighted by local economists.
The production of coconut biodiesel involves extracting oil from copra, which is then chemically processed. This biofuel, considered more environmentally friendly than traditional diesel, can be used alone or blended with other fuels without modifying engines. Currently, all copra used in the production comes from Kulili, a plantation owned by the Middleton family since the 1920s. Expansion plans could potentially meet the fuel needs of Madang province's population, pending government support.
