1.4 Current Feedstock for Biofuel Production
Generally, biofuel feedstock can be characterized into four groups.
1.4.1 Animal Fats
Fats and tallow from animals are the first cluster of feedstock for biofuel construction
(Wen and Johnson 2009). Animal fats such as chicken that removed from chicken
wastes fat are a low-cost feedstock for biofuel construction (Alptekin et al. 2014).
Contrasted with plant crops, these fats proposed a commercial benefit since they
are valued satisfactorily for alteration into biodiesel.
However, animal fat comprises great values of saturated fat that biofuels prepared
from this feedstock tend to gel and restrict request for winter-time use (Wen and
Johnson 2009). Also, there are significant concerns about biosafety when fats from
polluted animals are used (Atadashi et al. 2012).
1.4.2 Oils Derived from Various Crops and Plants
The second group is pure oils derived from soybean, canola, corn, flax, sunflower,
etc. (Wen and Johnson 2009). Currently, there are more than 350 probable herbal oil
harvests depending upon the weather and soil environments that utilized as the
leading conservative feedstocks for biofuel construction (Ghazali et al. 2015).
Most biofuels utilized in the world are prepared from soybean oil and rapeseed oil
by transesterification with alcohol (Ingenito et al. 2016). Rapeseed oil is the chief
biodiesel originating in Europe, while soybean oil is the greatest public origin for
biodiesel fabrication in Brazil, Argentina, and the USA (Mahmudula et al. 2017).
Also, olive pomace oil is a feedstock with hopeful potential for biodiesel production in the island of Crete, Greece (Tsoutsos et al. 2011).
The point that jatropha oil cannot be utilized for dietary purposes without
detoxification makes its usage as vitality or biofuel source exceptionally appealing.
Jatropha oil was used as an inorganic diesel substitute throughout the Second World
War (Akbar et al. 2009).
These oils are pure, and it makes a more quality. However, it can cause an
increase in commodity prices and worldwide food (Taparia et al. 2016; Wen and
Johnson 2009).
Lengthy utilization of crude herbal oils in diesel machines may expand carbon
deposits on the fuel injectors attributable to their limited ignition. This might lead to
a failing of device efficiency and cause mechanical harm (Atadashi et al. 2012).
Euphorbia holds high ability as a feedstock source for biofuel progress.
Euphorbiaceae-derived fuels have desirable properties. Among these are positive
