Algae to biofuel ! ground breaking patent

Dr. John W. Bebout, Principal Consultant for Bebout and Associates, have patented a process for growing algae for biofuels that promises faster growth
rates, higher oil production and  freedom
to locate commercial algae farms in rural areas.



 



Dr John W. Bebout  explained  that providing carbon dioxide  to algae is well-known to as much as double
both their production of lipids and  growth rate. Till date  the amount of CO2 required to grow the
thousands of acres of algae necessary for commercial production required
co-location with large industrial sources of CO2 such as power plants or large
factories. This severely restricted potential locations for large algae farms.



 



Now the new process uses marlstone as a media buffer as well as a source
of carbon and trace elements for enhanced algae growth.

Guidelines for algae industry




 A document on guidelines for the algae industry from ABO !



This
 document was authored by the ABO’s
Technical Standards Committee. The Technical standard committee was headed by
 by Jim Sears of A2BE Carbon Capture.



 



The
objective is to develop standards and best practices for the algae industry and
facilitate the flow of information. Nearly 20 industry experts have commented
and suggested
  on it.



 



One
of the key objective is to provide
 metrics and variables for estimating and
measuring the economic and environmental footprint and economic impact of an
algal production facility.


The
absence of common descriptive language has led to a lack of harmony among
technologists, researchers, life cycle analysis specialists and entrepreneurs
as they evaluate and promote algae technologies, said Mary Rosenthal,
Executive Director of ABO.
 


"This
confusion has made it hard for others to truly capture, analyze and quantify
algae technologies relative to one another. With a common language, such as the
one we and many volunteer stakeholders have proposed, we hope to bring more
clarity to the industry."

Algae bio-plastics

This is just another article on algae bio plastics for the novice.
It is looked at from the plastics industry.
Worth a look, tho.
Petroleum drying up will lead to a sharp crisis requiring to find new sources for the plastics industry. Moreover, environmental requirements and the green trends lead to a broad use of renewable raw materials.


Currently, bioplastic industry is using renewable material such as starches from corn, tapioca, wheat and potatoes in the manufacture of bio-based resins sometimes entering in competition with food uses.

Algae have some main potential advantages related to the growing speed and the cultivation conditions. They can rapidly grow, producing fifteen times more vegetable oil per hectare than other feedstocks and can be cultivated in seawater, saving fertile land and fresh water for food cultivation. Marine algae only require sunlight, seawater, carbon dioxide (CO2) and nutrients to grow converting overabundant CO2 into useful biomass.

Major companies such as Dow, Chevron, Shell, BP, Exxon collaborate with research centres, state organizations and small businesses to develop algal raw materials for bioplastics and biofuels production.

Obviously, there are some issues concerning cultivation, harvesting and treatments leading to some uncertainty for the breakthrough of this promising way. Alginic acid and alginate polymer derivatives are well-known as hydroswelling, gelling and thickening additives but they also have uses as material for dental impression and moulding for soft or delicate objects or, in combination with other polymers, for specific applications.

The true innovative breakthrough can come from algae-based plastic grades, the ethanol and other alcohol routes leading to biopolyethylene, bio-PVC or bio-EVA.

The biofuel way is of a great interest because of the huge amounts of targeted productions, several times the tonnage of conventional plastics, the use of processing methods of the petroleum industry and polymerization processes of the chemical industry.

Many other pathways are investigated, for example the use of dried algae fibres as polymeric reinforcement, the combination of sugar from green algae and clay to obtain nanomaterials, the use of Natural Oil Polyols (NOP) to produce foam cores for composites?

    A recent patent by Solazyme

    Some of the recent patents from Solazyme has been appreciated by the industry techies no end.
    Here is one well explained by OILGAE. It is about

    " Lipid Pathway Modification in Oligeneous Algae "

    Essentially when GE is done the engineered algae expresses a lipid pathway enzyme at an altered level compared to a wild-type of the non-engineered species. The lipid pathway enzyme is usually selected from the pyruvate dehydrogenase group, acetyl COA or acyl carrier protein.


    This is the kind of blogs I would like to read in this group.
