The document summarizes the MAB3 project, which aims to produce bioenergy carriers (ethanol, butanol, biogas) and high-value fish feed from macroalgae. The project will optimize cultivation, pretreatment, and conversion processes to produce liquid and gaseous biofuels from 80% of macroalgal sugars while using the remaining solids and sugars to produce protein-rich fish feed supplements. The 3-year, €3 million project involves 12 partners across 5 countries and seeks to demonstrate the technical and economic feasibility of a macroalgal biorefinery approach.
Microalgae have potential as a fish feed ingredient. Research is evaluating the nutritional value and functional properties of different microalgae species. Preliminary results found that Nannochloropsis oceania, Phaeodactylum tricornutum, and Isochrysis galbana vary in their protein, lipid, and amino acid content. Feeding microalgae may help reduce soybean meal-induced inflammation in salmon intestines. Further research is needed to improve the digestibility and cost-effectiveness of producing microalgae at commercial scales for use as sustainable fish feed ingredients.

The oil palm industry in Malaysia provides a high economic return to the country. Currently empty fruit bunch (EFB) is one of the solid wastes which is produced daily but have limited use whereby it is usually left as plantation site to act as an organic fertilizer for the plants to ensure the sustainability of fresh fruit bunch (FFB). However, this waste material have the potential to be transformed into high value-added products such as bioethanol, acids and compost using advanced biotechnology technique. The major drawback in biomass technology is the difficulty of degrading the material in a short period of time. Therefore, a pretreatment step such as hot-compressed water treatment is required to break the lignocellulosic compound to easily accessible carbon sources for further use to produce bioethanol. This research proposes an environmental friendly technology which could convert waste biomass to valuable bio-based chemicals and fuels which could be transferred easily to rural areas and small medium industries for wealth creation and for their own use in their agricultural fields.

7. Develop this process
is a sustainable and
economical way
within the next 10 -
15 years
Wijffels & Barbosa (2010). Science 329(5993): 796-799
To make the production
economically feasible, it is
essential to develop
cultivation systems in
which algae convert the
light with a high
photosynthetic efficiency
Bosma, R. et al. (2010). International Sugar Journal 112: 74-85.
8. MANY SCATTERED
ACTIVITIES
• Different locations
• Different designs
• Different measurements
• How to compare systems?
• How to learn from this process ?
9. Example, photosynthetic efficiency
Theoretical maximum photosynthetic efficiency 9%
10% of light lost by transmission x 0.90
5% of biomass lost during the night x 0.95
10% of energy used for maintenance x 0.90
Maximum photosynthetic efficiency in photobioreactors: 7%
• At lab scale a photosynthetic efficiency of 6% seems to
be within reach
• What about - Pilot scale 10 – 100 m2
- Extended time > 1 yr
• How to design/operate even larger (1-100 ha plants)?
