Abstract:
Biodiesel is a non-toxic, biodegradable, environmentally
friendly alternative diesel fuel, produced from food-grade vegetable
oils through a transesterification reaction with methanol and
an alkaline catalyst. Using not refined or waste oils as a feedstock
represents a convenient way to lower biodiesel production costs.
The main problem using this type of low-cost feedstock lies in its
high content of FFA (Free Fatty Acids), leading to the formation of
soaps during the transesterification reaction.
The use of Brassicaceae spp. (B. carinata, B. juncea) and Nicotiana
tabacum for biodiesel production is investigated. Using a LCA
(Life Cycle Analysis) we assess the sustainability of biodiesel production
from these two innovative cultivations in crop rotation.
B. carinata has high yield both in adverse conditions and under
low cropping system. The aim is to exploit Brassiacaceae spp. better
agronomic performances in areas characterized by unfavorable
environmental conditions for other cultivations. Moreover Brassicaceae
spp. tissues contain high concentrations of glucosinolates
that can be hydrolyzed to isothiocyanate by the plant enzyme under
conditions of physical injury. Biofumigation effect of isothiocyanate
release from soil-incorporated Brassicaceae spp. tissues is known to
reduce soil plant pathogens and it could be an alternative method to
chemical plant disease control measure. This is useful for Nicotiana
tabacum, susceptible to nematode infection, being an interesting
alternative oil seed cultivation due to its high yield patent selections
(Fogher et al.). Tacking advantage of all these Brassicaceae spp.
and Nicotiana tabacum characteristics it could be possible not only
to produce high yield of oil seeds but also to reclaim nematode
infected fields.
Vegetables oils produced from new kinds of oil seeds were
selected and de-acidified by the direct esterification reaction of
their FFA in presence of pure methanol and using solid acid resins
as heterogeneous catalysts in mild working conditions (T = 338 K).
