New Invention Transforms Organic Waste to 'Green' Power

A new treatment system for organic residues has been launched by CST Wastewater Solutions, promising to convert almost any organic residue or energy crop into biogas, valuable electricity or heat. CST Wastewater Solutions has partnered with Global Water Engineering (GWE) to supply the RAPTOR system, which stands for Rapid Treatment of Organic Residues.

A RAPTOR plant is a total solution, starting with logistics for handling the energy crop and ending with the production of biogas, green electricity or steam. In the RAPTOR process, the pre-treated and blended substrate slurry is transferred into a mixed digester that uses energy efficient and low maintenance mechanical mixing. The digester tank comes in sizes up to 12,000 m3. Optional extras include a foam breaker fan, a scum buster system and a bottom grit trap.

The digester tank is fully insulated, heated by recycling the digester content through a special heat exchanger.

The plant can handle:
• Food waste, such as market surplus, kitchen waste, off specification fruit and vegetables, and excess crops
• Agro-industry residues, like starch and sugar pulps, vegetable or potato waste.
• Industrial residues, such as brewery waste (spent grain), fruit processing waste, and paper mill sludge.
• Energy crops, for example corn (silage), various grasses, algae.

A New Breakthrough in Biogas Treatment

Membrane Technology and Research, Inc. has just won a $70,000 grant to study the use of a low cost process to remove toxins from the methane generated by anaerobic digesters. The process is based on a new family of polymeric membranes with unique permeability/selectivity characteristics. Phase I will consist of improving the membrane’s performance and capability for reproduction. If that’s successful, Phase II will test a demo model in the lab and in the field.

Power From Cattle Manure- An Alternative Energy Economy

Cattle manure and Alberta ingenuity are combining to produce a fledgling alternative energy economy.Two huge tanks with rounded, mushroom lids loom above the snowdrifts, the first glimpse of Alberta's oddest-looking electricity plant and also its greenest.About one megawatt of power flows out on the wires — enough power to run the next-door feedlot and turn on the lights in 700 homes in Vegreville and Two Hills.

The project starts with new technology invented by their company, Highmark Renewables, to turn cattle manure into biogas, a product similar to natural gas from the ground. Highmark calls it "renewable natural gas" (since there's an endless supply of manure) and with a little cleaning up, it could heat your home.Right now, Highmark burns its biogas to make electricity. The company has developed 40 secret recipes to turn almost any kind of organic waste — slaughterhouse waste, sugar beet waste, municipal sewage — into biogas.

LANCASTER COUNTY, Pa. - EnergyWorks, of Annapolis, Md., has agreed to build an anaerobic digestion plant on a poultry farm that would produce biogas from waste created by the chickens.

The plant will produce an odorless, colorless gas similar to natural gas that is produced when animal waste is decomposed by bacteria in the absence of oxygen.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
