Direct transesterification process in producing biodiesel from naturally grown algae in aged landfill leachate / Nurul Liyana Rosli
Conventional fuel that is currently used is diesel fuel. However, the use of diesel fuel have several problems, in which the feedstock of diesel fuel will diminishing and the burning of diesel fuel will lead to the air pollution. In order to overcome this problem, most researcher produced biodiesel...

Conventional fuel that is currently used is diesel fuel. However, the use of diesel fuel have several problems, in which the feedstock of diesel fuel will diminishing and the burning of diesel fuel will lead to the air pollution.

However, the research study focused in producing biodiesel using direct transesterification process by using naturally grown algae in Aged Landfill Leachate (ALL) since it require less time and using less solvent, and also it is more convenient to obtain the algae.
