Producing quality biodiesel with favourable environmental implications is of great importance
in order to achieve sustainable energy management. This research is focused on the impact
analysis of emissions from biodiesel produced through alkaline catalysed transesterification of
waste groundnut oil (WGO), waste soyabean oil (W$0) and crudepalm kernel oil {CPKO). using
SIMA PRO 7 .33. In this research, the comparative analysis of the emissions from 1 kg biodiesel
produced was carried out. Waste groundnut oil biodiesel emissions had the most pronounced
impact on human health : Waste groundnut oil biodiesel had 2.94 x 10"10 kg emissions, waste
soyabean oil biodiesel released 2.40 x 1 0"10 kg non-environmentally friendly substances, while
crudepalm kernel oil biodiesel had 1.85 x 10"10 kg emissions. On damage to ecosystem quality,
emissions from waste groundnut oil biodiesel biodiesel was 1.25 x 10·3 kg, 9.95 x 10·• kg
emissions from waste soyabean oil biodiesel and 4.39 x 10·• kg emissions f rom crudepalm
kernel oil biodiesel. The result of damage to climate change show ed that waste soyabean oil
biodiesel contributed the most wit h 1 .54 x 1 o·• kg C0

Single score result showed that the increasing order of damage on the 3 categories considered
is human health, climate change and then ecosystem quality.
