Algae in Packaging Industry in 2010

Breakthrough products are enabling manufacturers to make the switch to environmentally responsible, sustainable packaging,” said Frederic Scheer, founder and CEO of Cereplast.  Their  algae-based bioplastics, currently under development, will soon open up a whole new source of feedstock and result in a broad range of new applications.

“Many of the largest retailers have already made in-roads with programs designed to adopt alternative   packaging. A lgae as biomass can be a significant renewable resource and be used as a raw material for biopolymerfeedstock.

“Algae can help close the loop on polluting gases and can be a significant renewable resource,” he said. “Algae-based resins represent an outstanding opportunity for companies across the plastic supply chain to become more environmentally sustainable and reduce the industry’s reliance on oil.”

Microalgae oil prevents Heart attack

DHA-microalgae oil proves to be better source of EPA, when compared to flax seed oil. This isbecause ALA from flax must be converted into DHA then converted into EPA, whereas, DHA from microalgae only has to be converted into EPA. That is one less enzymatic step to go through!In one study, vegetarians that do not have enough EPA and DHA, supplemented with 1 gram of microalgae oil derived DHA per day for eight weeks, and significantly increased their levels of both DHA and EPA (Lipids 40 (8): 807-814).

These results indicate that DHA derived from microalgae is a very good source of DHA and EPA compared to ALA derived from flax oil. Given the fact that DHA from algae oil is an exceedingly better vegetarian source of omega-3 fatty acids, the question is, does it have the same health benefits as fish oil?

The answer is yes.

Designer Algae for photobiological hydrogen production


Algae buildings solves Climate issues

The future of green technology is algae-cultivating buildings, synthetic trees, and heaps of white roofs, according to the U.K.’s institution of Mechanical Engineers. Andrew McFaul.

Cultivating algae to make liquid fuel is one of the most active areas of study in biofuels. The institution is recommending that algae be amalgamated into buildings so algae can be grown at a big scale.

How synthetic trees, which capture carbon from the air, could be deployed alongside wind turbines.

Engineers envision that long plastic tubes, called photobioreactors, be integrated into building designs or retrofitted onto existing skyscrapers.

Energy Secretary Steven Chu has in public offered this comparatively low-tech approach, which was studied in-depth at the Lawrence Livermore lab last year.

The shape of things to come?Climate issues fixed by these algae covered buildings.

Green Algae ushers in paper batteries

After nanofarming of algae to suck out oil from algae, now nano batteries from algae!

Scientists are working on the development of paper-based batteries made from algae to power electronics in the future.

A report in Live Science says that scientists from around the world are working towards developing thin, flexible, lightweight, inexpensive, environmentally friendly batteries made wholly from nonmetal parts. Among the most hopeful materials for these batteries are conducting polymers.

However, until now these are not viable for use in batteries – for example, their ability to hold a charge often reduces over use. The answer to this new battery turned out to be green algae called Cladophora. This algae makes an unusual kind of cellulose characterised by a very large surface area ? 100 times that of the cellulose found in paper.

This permitted the researchers to considerably increase the amount of conducting polymer available for use in the new device, allowing it to recharge better, hold and discharge electricity.
That is very interesting.

“We have long hoped to find some sort of constructive use for the material from algae blooms and have now been shown this to be possible,” said researcher Maria Stromme, a nanotechnologist at the famous Uppsala University, Sweden.

The new batteries comprised extremely thin layers of conducting polymer just 40 to 50 nanometers in width, coating algae cellulose fibres only 20 to 30 nanometers wide that were gathered into paper sheets.

They could hold 50-200 percent more charge than similar conducting polymer batteries and once better optimised, they might even be competitive with commercial lithium batteries, the researchers noted. They also recharged much faster than the usual rechargeable batteries.

Recharge in quick time:

While a regular battery takes at least an hour to recharge, the new batteries could recharge in 8-11 seconds. The new battery also showed a remarkable increase in the ability to hold a charge over use.

While a comparable polymer battery showed a 50 percent dip in the amount of charge it could hold after 60 cycles of discharging and recharging, the new battery showed just a 6% dip through 100 charging cycles. The researchers proposed that their batteries may be suitable for applications concerning flexible electronics like clothing and packaging.

Imagine a thin birthday card singing a song! These paper batteries are environmental friendly.

Algae based Waste water treatment system reduces cost

Oldcastle Precast, a manufacturer of precast and polymer concrete products, has signed an exclusive agreement with Indianapolis based Algaewheel Technologies LLC to sell Algaewheel technology as part of its wastewater treatment systems.

Oldcastle’s new Maxpac Package Plant Wastewater System combines Algaewheel technology – simple clarification processes enhanced by the natural coagulating effects of algae filaments – and disinfection to result in effluent treated to secondary and tertiary standards.

During the treatment process, algae produce oxygen to feed the bacteria, and bacteria produce CO2 to feed the algae, thus significantly reducing the carbon footprint. In the process, nutrients and BOD are removed from the waste stream. The packaged plant system is currently designed for use in smaller-scale decentralized wastewater treatment applications. A larger-capacity system is under development.
This is eco friendly too! Reducing carbon footprint is an added bonus.
