1 BIO-FUEL PRODUCTION FROM MICROALGAE SYED ISA SYED ALWI CEO of Algaetech International Malaysia

2 Who We Are? Algaetech Sdn Bhd ( Algaetech ) was incorporated in Malaysia year 2004 as an investment holding company with group activities in micro algae research, development, consultancy, production and marketing for renewable energy and high value products of anti-oxidants (or functional foods) Research and development of algae for bio fuel Cultivation of Heamatococcus pluvialis for Astaxanthin production Consultancy of micro-algae development for renewable energy and high value products from flue gas ReNew RENEWABLE ENERGY WORLD SUMMIT

3 Algaetech s Expertise 1. Research & Development of Algae for functional food and bio-fuels 2. Consultancy in CO2 Sequestration, Carbon Credit Management, Emission Control management (Carbon Capture) and Integrated Renewable Energy Plant combines with algae cultivation and production 3. Algae Integrated Management System (AIMsys) 4. Primary production of high value products and anti oxidants such as Spirulina, astaxanthin 5. Sales & Marketing of algae nutritional product thunder brand named Premia.

4 Most important renewable resources of energy nowadays is biofuel. Two main sources of the production of biofuel; the first type of raw materials in this industry are agriculture-based materials, second type are organic wastes based. Biofuel: solid, liquid, gaseous fuel consisting of, or derived from biomass. Biofuel often considered a transition renewable energy source to hydrogen fuel cell, nuclear, solar or wind Current ethanol capability: 6.5 billion gallons a year 77 new ethanol plants and 8 expansion projects underway 2.2 billion bushels were used to produce ethanol in 2006/ billion bushels were expected to be used in 2007/2008 Issues with land Require extensive government intervention (policy) Introduction Recently living organisms or their metabolic by-products, such as manure from cows. Fossil fuels: derived from long dead biological materials.

5 Why Biofuel? Biofuel production and consumption ensures that the natural Carbon cycle to be 100% achieved. Decrease in Carbon Dioxide rates in the atmosphere which in turns will have the greatest effect on the environment and a way to end global warming. For example, A crop of plants used to produce a barrel of biofuel will absorb exactly the same amount of Carbon Dioxide as emitted from burning the barrel produced.

6 How is Biofuel Made? Originally came from the sun captured through photosynthesis by the plants and used as feedstock for biofuel production, and stored in the plants' cells. Various plants and plant derived materials are used for biofuel manufacturing. Sugar crops ; Natural oils from plants like oil palm, soybean, or algae; Wood and its by products; Flaxseed, rapeseed (primarily in Europe ); Waste from industry, agriculture, forestry, and households. And of course algae

7 We Introduced Algae Fuel Algae fuel, also called algal fuel, algaeoleum or third-generation biofuel: Biofuel which is derived from algae. During photosynthesis, algae and other photosynthetic organisms capture carbon dioxide and sunlight and convert it into oxygen and biomass. Up to 99% of the carbon dioxide in solution can be converted, which was shown by Weismann and Tillett (1992) in large-scale open-pond systems. Biofuel Processing: The first route involves using oil which is extracted from plant sources like Jatropha, algae to produce bio SPK (Bio derived synthetic paraffinic Kerosene) by cracking. This Bio SPK can be further processed to produce Jet fuel. The second route involves processing solid biomass using pyrolysis to produce pyrolysis oil which is then cracked to produce FT SPK (Fisher Tropsh Synthetic Paraffinic Kerosene). Algae is processed via the first route.

10 Cultivation of Nannochloropsis The cell division of Nannochloropsis usually occurs in dark condition and the best growth temperature range is between 20 C and 25 C Best salinity condition is 25-30ppt and the highest amount of lipid found at 35ppt The ph of culture medium has to be within the range of 7.5 to 8.0. The media which is utilized for the growth of Nannochloropsis is modified f/2 medium

14 Harvesting & Drying Separating algae from the growth medium in order to concentrate and is followed by solar drying for long term storage Harvesting is done by : Physical methods Filtration Centrifugation Chemical methods Flocculation 14

15 Drying Sunlight is used to remove the remaining moisture content 15

16 Extraction of Algal Oil Algae oil can be extracted primarily by : Mechanical Expression/Expeller press Ultrasonic-assisted extraction Chemical Hexane Solvent Method Soxhlet extraction Supercritical fluid Extraction

17 Soxhlet Oil Extraction 3000 ml of normal hexane was poured into flask and 300 grams of dried, powdered biomass added to the thimble and the mantle heater adjusted to 70 c. The Soxhlet turned on for 24 hours. Miscella - It is a technical term that means a mixture of the extracted oil and the extracting solvent. 17

18 Conversion of Algae Oil into Biodiesel Algal oil is highly viscous, with viscosities ranging times those of no. 2 Diesel fuel Reduction in viscosity is important to make high-viscous oil a suitable alternative fuel for diesel engines There are a number of ways to reduce vegetable oil's viscosity: Transestrification, Pyrolysis Micro Emulsion Blending Thermal depolymerization

21 Biofuel from Algae Promise & Challenges Microalgae cultivation on a large scale could considerably diminish land use, mainly, arable land, bio fuels production could come from arid and semi-arid land, on which microalgae could be cultivated. This alternative has not been considered in IEA studies. It represents the opportunity to increase bio fuels share in the road-transport sector without competition with land for food production. Furthermore, microalgae present a much higher productivity than terrestrial crops and forest. Productivity of approximately 70 ton/ha/year for algae is estimated in comparison to 15 ton/ha/year for terrestrial plants. An interesting review related to the microalgae potential to produce biodiesel, in which he emphasized that microalgae appear to be the only source of renewable biodiesel able to meet the global demand for transport fuels.

22 Benefits of Using Algae Bio-Fuel Biofuels could reduced greenhouse-gas emissions by 60 to 80 percent. The yields of oil and fuels from algae are much higher ( times) than competing energy crops Algae can grow practically anywhere (desert and marine environments), thus ensuring that there is no competition with food crops. Algae are excellent bioremediation agents - they have the potential to absorb massive amounts of CO 2 and can play an important role in sewage and wastewater treatment. Algae are already being used in a wide variety of industries and applications, and many newer applications are being discovered. Such a wide range of end-uses enable companies to produce both fuels and nonfuel products from the same algae feedstock
