Chlorella
vulgaris ;
biodiesel
To assess the environmental
impact of biodiesel from
microalgae as
technologically immature
process and to identify
barriers to large-scale
environmental sustainability.
Nutrient supply was
compared with nutrient
starvation; wet and dry
extraction was tested; AD
and nutrient recycle were
used
Infrastructure,
cultivation,
dewatering, extract
& convert, transport
& distribute,
combustion.
Open raceways
LCA of virtual

Microalgal
biodiesel
To evaluate an industrial-scale
model for microalgal
biodiesel production in
photobioreactors and
compare microalgal biodiesel
with soybean-based diesel
and petroleum diesel
Cultivation,
