Problem statement
• Growing concern regarding necessity of energy resources
and the environmental impact and demand of fuel sources
has increased interest in the research of alternative sources
of energy. Biodiesel is a fuel produced from renewable
resources, it is a clean alternative fuel, which has drawn the
attention of energy researchers for the last two decades due
to the disturbing effect of climate change caused by
petroleum diesel fuel(Degfie et tal, 2019). The qualities of
biodiesel produced from waste vegetable oil and fresh
vegetable oil and the positive impact on the alarming
change in climate today.

Objectives
• Main objectives
The aim of the study is to determine the differences in
quality of biodiesel when using fresh oil and waste/spent oil.
• Sub-objectives
To establishing the differences between the two oils.
To establish the difference in biodiesel yield with increasing
carbons in the alcohol.
To determine the extent of grade differences in the
biodiesels from the two oil sources.
