CCRES: Chinampa Aquaponics

CCRES: Chinampa Aquaponics | Algae | Scoop.it
CCRES's insight:
Chinampa is a method of ancient Mesoamerican agriculture which used small, rectangle-shaped areas of fertile arable land to grow crops on the shallow lake beds in the Valley of Mexico.

CCRES's comment, January 4, 2013 3:21 AM
Irrigated by the surrounding lake water, the chinampas were fertilized by digging up the nutrient-rich mud from the bottom of the canals and also by using human waste from the city itself. In this way, Tenochtitlan was able to better fertilize its crops while treating its wastewater― creating a healthier living environment for all. Crops were easily transported to market along the many canals and lakes surrounding the chinampas. When the Spaniards arrived it did not take them long to dimantle the complex system and put in place traditional monocropping. Today, some chinampas survive in the Xochimilo area close to Mexico City. They are cared for in the traditional way and create both food and an opportunity for a healthy tourist industry. Mexico city is currently trying to create a waste-water treatment system incorporating the use of chinampas similar to the ones used by the Aztecs so long ago.

CCRES's insight:

What is Spirulina Algae ?

 Spirulina is a microscopic blue-green algae that exists as a single celled organism turning sunlight into life energy.It is one of the first life forms designed by nature more than 3.6 billion years ago. Spirulina contains billions of years of evolutionary wisdom in its DNA and is an offspring of earth’s first photosynthetic life forms.Under the microscope, Spirulina is a blue-green color and has the appearance of a spiral of long thin threads.

CCRES: Carbon capture and consumption

CCRES: Carbon capture and consumption | Algae | Scoop.it
Could it Eliminate the Need for Wastewater Aeration? Algal blooms have always proved a challenge for the water industry. Yet could this organic matter,with the help of wastewater nutrients, be turned into a biofuel and help alleviate fossil fuel shortages? Tom Freyberg investigates the European funded All-Gas project. First generation biofuels from crops never really bloomed into a fruitful harvest. Opponents criticized using up valuable land to grow crops and fuel the cars of the rich, instead of filling the stomachs of the poor. Second generation biofuels – made from biomass - have proved a lot harder to extract the required fuel and fully crack. And then along came algae. Unlike first generation biofuels, algae can be grown using land and water not suitable for plant and food production. Consuming solar energy and reproducing itself, algae generates a type of oil that has a similar molecular structure to petroleum products produced today. As if this wasn't enough – algae growth also consumes carbon dioxide, a known major greenhouse gas (GHG). As a result of the apparent benefits the race is on to commercialize second and now third generation biofuels, in the case of algae. Continents and companies are putting money where their mouths are to find out how what we thought was simply a green weed growing in the sea could be the answer to inevitable fossil fuel shortages.

CCRES: Way to Create Biofuels

CCRES: Way to Create Biofuels | Algae | Scoop.it

Is there a new path to biofuels hiding in a handful of dirt? 

Lawrence Berkeley National Laboratory (Berkeley Lab) biologist Steve Singer leads a group that wants to find out. They’re exploring whether a common soil bacterium can be engineered to produce liquid transportation fuels much more efficiently than the ways in which advanced biofuels are made today.

The scientists are working with a bacterium called Ralstonia eutropha. It naturally uses hydrogen as an energy source to convert CO2 into various organic compounds.

The group hopes to capitalize on the bacteria’s capabilities and tweak it to produce advanced biofuels that are drop-in replacements for diesel and jet fuel. The process would be powered only by hydrogen and electricity from renewable sources such as solar or wind.

The goal is a biofuel—or electrofuel, as this new approach is called—that doesn’t require photosynthesis.

Why is this important? Most methods used to produce advanced biofuels, such as from biomass and algae, rely on photosynthesis. But it turns out that photosynthesis isn’t very efficient when it comes to making biofuel. Energy is lost as photons from the sun are converted to stored chemical energy in a plant, which is then converted to a fuel.

Palm Kernel Shells as Biomass Resource

Palm Kernel Shells as Biomass Resource | Algae | Scoop.it

Palm kernel shells (or PKS) are the shell fractions left after the nut has been removed after crushing in the Palm Oil mill. Kernel shells are a fibrous material and can be easily handled in bulk directly from the product line to the end use. Large and small shell fractions are mixed with dust-like fractions and small fibres.

Moisture content in kernel shells is low compared to other biomass residues with different sources suggesting values between 11% and 13%.

Pretreatment of Lignocellulosic Biomass

Pretreatment of Lignocellulosic Biomass | Algae | Scoop.it

Lignocellulosic biomass consists mainly of lignin and polysaccharides cellulose and hemicellulose. Compared with the production of ethanol from first-generation feedstocks, the use of lignocellulosic biomass is more complicated because the polysaccharides are more stable and the pentose sugars are not readily fermentable by Saccharomyces cerevisiae.

Algae Biorefinery - Promise and Potential | EcoMENA | Algae | Scoop.it

High oil prices, competing demands between foods and other biofuel sources, and the world food crisis, have ignited interest in algaculture (farming of algae) for making vegetable oil, biodiesel, bioethanol, biogasoline, biomethanol, biobutanol and other biofuels. Algae can be efficienctly grown on land that is not suitable for agriculture and hold huge potential to provide a non-food, high-yield source of biodiesel, ethanol and hydrogen fuels.

Thermal Technologies for Biomass Conversion

Thermal Technologies for Biomass Conversion | Algae | Scoop.it

A wide range of thermal technologies exists to convert the energy stored in biomass to more useful forms of energy. These technologies can be classified according to the principal energy carrier produced in the conversion process. Carriers are in the form of heat, gas, liquid and/or solid products, depending on the extent to which oxygen is admitted to the conversion process (usually as air).

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.

PHILIPPINES: Algae Master Plan for the Philippines

PHILIPPINES: Algae Master Plan for the Philippines | Algae | Scoop.it

Work is underway to create a five-year plan to be used as a roadmap for developing commercial uses for Philippine strains of microalgae. Known as the Algae Research and Commercialization Master Plan, one of the plan’s primary pathways leads to development of microalgae as aquafeeds.

 

This year, the Philippine Agriculture, Aquatic and Natural Resources Research and Development (PCAARRD) released P10 million to start off the National Aquafeeds Research and Development Program. About 60 species of microalgae have already been screened for food and aquaculture In the Philippines.

 

 Through the algae masterplan, the country is in a bid to develop at least five local strains of microalgae for the world market for algal products: Chlorella vulgaris, Isochrysis, Nannochloropsis spp., Tetraselmis spp., and Spirulina platensis.

 

Other than feed development, the algae masterplan will direct algal research towards germplasm collection, preservation and maintenance, processing, and value-adding for production of bioactive compounds, nutraceuticals and functional foods, nanomaterials, crop protectants and algal polysaccharides; and development of high-rate algal production systems including design and local fabrication of photobioreactors.

 

The Philippines Congressional Committee on Science, Technology and Engineering (COMSTE) has identified the masterplan as one of their six Science and Technology (S&T) Innovation Clusters. The S&T innovation cluster concept involves strategic alliances among academic institutions, research consortia, private and foreign companies, and government funding institutions to deliver technologies that would fuel fledging industries towards global competitiveness.

New ways to turn photosynthetic green algae into tiny “green factories” for producing raw materials for alternative fuels.  

Overturning two long-held misconceptions about oil production in algae, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory show that ramping up the microbes’ overall metabolism by feeding them more carbon increases oil production as the organisms continue to grow. The findings — published online in the journal Plant and Cell Physiology  — may point to new ways to turn photosynthetic green algae into tiny “green factories” for producing raw materials for alternative fuels.
