Abstract

In response to the pressing need for urgent decarbonization initiatives, it is vital to address the substantial contribution of fossil fuels to global CO2 emissions. Within Malaysia, urgent decarbonization is essential as the country is committed to reducing carbon intensity by 45% by 2030 and aiming for net-zero emissions by 2050. The transport sector stands out as a major driver of CO2 emissions, contributing 28.8% of total fossil fuel combustion, well above the global average. Boats, in particular, play a significant role in carbon emissions, with outboard-powered fishing boats producing around 2000 ppm and inboard-powered ones emitting approximately 379 ppm of carbon. Adding to the challenge is the inappropriate disposal of waste cooking oil (WCO) in Malaysia, especially from the hospitality industry, generating 17,000 tonnes of food waste and 21,000 tonnes of non-food waste. To tackle this issue, a collaborative project involving several universities aims to convert WCO into biodiesel, which can be used as a sustainable fuel source for water transportation, including fishing boats. The project also involves stakeholders from the hospitality and fishery industry. This initiative aims to address multiple challenges - waste management, carbon emissions from boats, and dependence on fossil fuels in the transportation sector. By converting WCO into biodiesel and implementing it in boats, Malaysia can take significant strides towards a more sustainable and environmentally friendly future. The project’s timeline includes various stages, from WCO conversion to renewable biodiesel, assessing combustion performance, evaluating engine durability, conducting life cycle assessments, and gauging fishermen’s readiness for biodiesel adoption. Through these efforts, Malaysia can make meaningful progress in decarbonizing the water transportation sector and combating the adverse effects of climate change.
