Dear Kieth and lowell.
We have been growing algae of various types for a good number of
years starting with Spirulina as a food and then venturing into
algaes suitable for lipid production.. First we had to learn to grow
algae and came to the level of designing a closed loop system that
would allow the production of algaes under a broad range of climatic
and geographic conditions ....in that, we succeeded... we have been
growing dunaliela and butyrococcus with success in our research pond
here at ecogenics center.. although we have been producing ethanol
and methane for many many years and were well aware of the potential
of algae for the production of lipids (oils) for biodiesel. we had
not, untill very recently ,actually produced biodiesel.. we have now
reached that goal with a fair amount of consistancy and are now
prepared to enter a new phase in our development program... that
is.. the extraction of oil from our algaes and the consequent
production of biodiesel from the resulting oils. we are soon
embarking on a program of study involving extraction techniques and
after that will undertake the necessary steps to make biodiesel from
those oils.We are taking very cautious baby steps towards that
goal.financial constraints have made it prudent to go slowly and
deliberatly in all our endeavours one look at our website and one can
see that we have touched upon many areas of R&D over the years.we
expect that with some wise investment of time and money we will
successfully adress the extraction and production phase of the algae
to biodiesel program..we will of course keep you posted as to our
progress....in the meantime we are ready to produce biodiesel from
wvo...we have made the necessary modifications to our distillery so
we can do this...
