What is it about?

This is a start-up study examining the behaviour and performance of palm oil mill effluent in the production of biohydrogen and biomethane gases. Factors such as process stability and biogas production are considered in the conversion of palm oil discharge using a two-stage up-flow anaerobic sludge fixed film (UASFF) bioreactor. In addition to the conventional methane production, this research provides an efficient method of palm oil wastewater treatment with a higher value output of hydrogen gas production. With the support of industries and government, this research could serve as a golden standard in palm oil waste treatment as well as be implemented as part of a sustainable approach in various industrial organic waste management system.

Why is it important?

The rapidly diminishing energy source has imposed a growing demand on resource conservation and green energy production initiatives. Apart from utilizing methane as an organic byproduct to generate energy, hydrogen gas production via industrial wastewater treatment promises a cleaner energy source. The outcome of this research could be used as a technical basis for the development of larger-scale prototype design of UASFF to produce biohydrogen and biomethane gases from palm oil discharge treatment.

Perspectives

Anaerobic treatment is a well-established technology for treatment of wastes and wastewaters as it is technologically simple with a low energy consumption workflow. Moreover, it is an efficient, economical and environmental-friendly method. The final product of anaerobic digestion is biogas, a mixture of methane and hydrogen, which could potentially be leveraged in the form of renewable energy source. In compliance to the UN’s Sustainable Development Goals, this research aims to fulfil the following: Goal 6: Ensure availability and sustainable management of water and sanitation for all Goal 7: Ensure access to affordable, reliable, sustainable and modern energy for all
