Description:

”Given the right conditions, algae can double its volume overnight. Microalgae are the earth’s most productive plants –– 10 to 15 times more prolific in biomass than the fastest growing land plant exploited for biofuel production. While soy produces some 50 gallons of oil per acre per year; canola, 150 gallons; and palm, 650 gallons, algae can produce up to 15,000 gallons per acre per year. In addition, up to 50 percent (or more) of algae biomass (dry weight) is comprised of oil, whereas oil-palm trees—curr

In smaller countries, like Croatia, where oil demand is low, and emission standards are poor, algae biofuel has the potential to significantly reduce reliance on foreign oil.

Biodiesel from Microalgae


The oil from the algae can be used for any combustion process. An even wider range of use for algae oil is obtained by the transesterification to biodiesel. This biodiesel can be blended with fossil diesel or can be directly driven as pure biodiesel B100.

Biodiesel from microalgae has a comparable quality as rapeseed methyl ester and meets the standard EN 14214. At biodiesel production about 12% glycerin is produced as a by-product. This glycerin is a valuable resource for the production of algae in closed ponds, the heterotrophic processes. Thus, the entire algae oil can be used as fuel.

Fish Food


Algae provide a natural solution for the expanding fishing industry:

High-protein fish food
Replacement for existing fish meal production
Algae have nutrients of many young fishes available


The fishing industry recorded an annual growth of over 10% and, according to experts, will beat the global beef consumption in 2015.

The Technology developed by CCRES offers the opportunity to deliver part of the needed proteins for fish farming on the resulting algal biomass.
Protein for the food industry


The demand for high-quality protein for the food industry has been growing rapidly over the years.

The big growth opportunities are:

Weight control
Fitness and Sports Nutrition
Food supplements


The market volume in the protein sector is continously growing and at the rate of US $ 10.5B in 2010 and according to experts, will steadily increase to approx. $25B until 2030.

“There is intense interest in algal biofuels and bioproducts in this country and abroad, including in US,Australia, Chile, China, the European Union, Japan, Korea, New Zealand, and others,” says Branka Kalle, President of Council Croatian Center of Renewable Energy Sources (CCRES).

Advantages algae has over other sources may make it the world’s favored biofuel. Algae could potentially produce over 20 times more oil per acre than other terrestrial crops.Algae avoids many of the environmental challenges associated with conventional biofuels.Algae does not require arable land or potable water, which completely avoids competition with food resources.
“The Asia Pacific region has been culturing algae for food and pharmaceuticals for many centuries, and these countries are eager to use this knowledge base for the production of biofuels,”says Zeljko Serdar, President of CCRES.

Without sustained high prices at the pump, investment in algae will likely be driven by demand for other products. In the short term, the growth of the industry will come from governments and companies seeking to reduce their environmental impact through carbon collection.

CCRES First Pilot-scale Algal Production Facility

Nears Completion

An algal production facility located at the CCRES Research Farm will be operational by June. This is the first facility at Croatia that can produce large amounts of algal biomass.

The facility is a 800 square-foot greenhouse that will accommodate two raceway pond systems, four large flat panel photobioreactors and one custom-made revolving attachment-based photobioreactor. The total production capacity will be 100-200 dried kilograms of algae biomass per year.

CCRES Researchers will use the various production systems to quickly grow algal biomass for various research purposes including the production of renewable fuels, food or animal feed. "This greenhouse algal production system will be a test bed for different researchers to try out their algal production capability at a large scale," said Zeljko Serdar, President of CCRES ALGAE TEAM.

"The raceway pond systems are each 20 feet in length and both systems can hold approximately 1,000 liters of algae culture medium. Raceway pond systems are the most common method for large-scale algae cultivation. At first glance, the four flat panel photobioreactors appear to be large tanks," said Ilam Shuhani, Chairman of the CCRES Supervisory Board and professor-in-charge of the greenhouse.

Algae are emerging to be one of the most promising long-term, sustainable sources of biomass and oils for fuel, food, feed, and other co-products. What makes them so attractive are the large number and wide variety of benefits associated with how and where they grow.

Nearly all these benefits stem from the fact that these plants have evolved over billions of years to produce and store energy in the form of oil, and they do this more efficiently than any other known natural or engineered process.

Here are 10 reasons why algae are a promising new source of fuel and other products:

1) Algae Grow Fast
Algae can double their numbers every few hours, can be harvested daily, and have the potential to produce a volume of biomass and biofuel many times greater than that of our most productive crops.

2) Algae Can Have High Biofuel Yields
Algae store energy in the form of oils and carbohydrates, which, combined with their high productivity, means they can produce from 2,000 to as many as 5,000 gallons of biofuels per acre per year.

3) Algae Consume CO2
Like any other plant, algae, when grown using sunlight, consume (or absorb) carbon dioxide (CO2) as they grow, releasing oxygen (O2) for the rest of us to breathe. For high productivity, algae require more CO2, which can be supplied by emissions sources such as power plants, ethanol facilities, and other sources.

4) Algae Do Not Compete With Agriculture
Algae cultivation uses both land that in many cases is unsuitable for traditional agriculture, as well as water sources that are not useable for other crops, such as sea-, brackish- and wastewater. As such, algae-based fuels complement biofuels made from traditional agricultural processes.

5) Microalgal Biomass Can Be Used for Fuel, Feed and Food
Microalgae can be cultivated to have a high protein and oil content, for example, which can be used to produce either biofuels or animal feeds, or both. In addition, microalgal biomass, which is rich in micronutrients, is already used for dietary supplements to advance human health.

6) Macroalgae Can Be Grown in the Sea
Macroalgae (seaweeds) are grown in the sea, or even on land with seawater, and their sugars can be converted into biofuels and chemicals.

7) Algae Can Purify Wastewaters
Algae thrive in nutrient-rich waters like municipal waste waters (sewage), animal wastes and some industrial effluents, at the same time purifying these wastes while producing a biomass suitable for biofuels production.

8) Algal Biomass Can Be Used as an Energy Source
After oil extraction, the remaining algal biomass can be dried and “pelletized” and used as fuel that is burned in industrial boilers and other power generation sources.

9) Algae Can Be Used to Produce Many Useful Products
Algae can be cultivated to produce a variety of products for large to small markets: plastics, chemical feedstocks, lubricants, fertilizers, and even cosmetics. See other products algae is used for here.

10) The Algae Industry is a Job Creation Engine
Algae can grow in a wide variety of climates in a multitude of production methods, from ponds to photobioreactors to fermenters, and thus will create a wide variety of jobs throughout the United States, from research to engineering, from construction to farming, from marketing to financial services.
