3WHAT ARE AQUATICBIOFUELS?
4- Why ALGAE?
- Does not compete with agriculture
- High yield per acre
- Contains no sulphur therefore no SO2 emissions
- Non toxic and highly biodegradable
- Does not require soil for growth
- Uses as little as 30cm of water per year per
hectare (open pond system) - Adaptable anywhere even at great distances from
water - Abatement of CO2 carbon neutral
5Oil yield per hectare of microalgae significantly
exceeds other common oil sources such as soya
and rapeseed
33 times more than rapeseed
88 timesmore than soya

PBR Photo Bio-Reactor
6- Photo Bio-Reactors?
- Using Photo Bio-Reactors (PBR) is expensive but
it is a State of the Art Technology, it produces
higher yields than other systems. Recent and up
to date technologies demonstrate that
somePBRs are not as expensive to produce and
could be a solution for developing countries
7Microalgae Biofixation Process with wastewater
8Open pond wastewater has demonstrated
productivities of 100 tonne/ha/yr tonne per
hecatre per year.

10- Aquatic Biofuels Challenges, Opportunities and
Gains - Algae
- Cost intensive especially for Photo Bio-Reactors
may be suitable for Higher Income Countries. - Open pond systems are much more viable although
real costs are still not available,
by-products can however make the process
completely viable. - Abatement of CO2 Mitigation from the conversion
of the algal biomass to renewable fuels
directly substituting fossil fuels coal and gas - Each tonne of microalgae biomass produced
about a tonne of CO2 abated - Both algal to bio-fuel technologies are therefore
completely Carbon Neutral
11Adaptability to Mediterranean Region Algae
production with Photo Bio-Reactors (PBR) More
suitable for Higher Income Countries (due to
higher start-up costs) Algae production with
MBP (Microalgae Biofixation Process) More
suitable for Lower Income Countries (due to
lower start-up costs)
12 13- FISH WASTE From Aquaculture Farms
-
- Press the fish waste
- Oil is extracted through a water separation
process at 90o C -
- Manganese (Mn), methanol (9) and caustic soda is
added. - The by-product glycerine is sold to the cosmetic
industry and the residues are made into
fishmeal. -
- 1kg of fish waste can produce just over 1lt of
bio-diesel.

16- Fish Waste - Key points and feasibility for
Mediterranean Region - Technology is adaptable and transferable in many
regions of the Mediterranean . - It can provide livelihoods through the
production of fish, and produce local energy
free from GHG emissions. - Relatively little investment required.
- Fish waste could also promote more efficient
utilization of aquatic living resources and
generate additional income for fishers' and fish
farmers - communities.
- Adaptable on large fishing trawlers.
- Fishing Ports
17- Fish waste Advantages and Disadvantages
- The oil produced for bio-diesel is already
marketable as fish oil, more fish oil would
have to be produced to cater for the demand in
bio-diesel this may disrupt fish oil markets. - The technology is in place (Viet-Nam and
Honduras) and is transferable to regions of
the Mediterranean as pilot project studies.
Mississippi State University is experimenting
using the waste from shrimp, but using a
slightly different process.
