Review on different methods of biofuel production from biomass and plastic / Nurshuhadah Zulkifli

The rising usage of fossil fuels, which are non-renewable and unsustainable, has contributed to environmental contamination. Therefore, a different approach has been developed to replace the heavy reliance on fossil fuels with sustainable and renewable resources. The use of renewable energy can help to cut CO2 emission. This is because biomass is a renewable energy source, it is a different technique to manufacture biofuel. The plant-based material known as biomass is used as fuel to generate heat or power. However, due to the massive amount of garbage generated by many everyday living sources, plastics are also frequently used to make fuel. In addition to allowing plastic to breakdown over time, which is beneficial for oil production, this method aids in recycling this material to prevent environmental damage. Therefore, this leads to the study of mixing biomass and plastic to see the efficiency of the involved method. This review is focusing on producing liquid fuel which are pyrolysis and hydrothermal liquefaction. The mixture of biomass and plastic give many benefits in term of the cost, the increase of product yield, enhancement in heating value, viscosity and acidity. These present study attempts to review the potential biomass and plastic as biofuel and also to compare the methods on producing biofuel.
