Can sewage and algae solve our energy crisis?

Len Calderone, Contributing Editor of Altenergymag.com, reports that with the growing trends of energy consumption, existing production is unsustainable. If the world maintains existing policies in energy usage and production, global energy demand will rise by 1.5 % per year on average through 2030, while fossil…

Wastewater Treatment

The release of poorly treated wastewater into natural resources impacts human health and the natural environment. Several wastewater treatment works in the Limpopo Province of South Africa are in high and critical risk situations…

Algae Systems upgrades direct potable reuse

A new wastewater treatment that uses algae technology to clean sewage, in what its backers are calling a “twist” on direct potable reuse (DPR). The idea won an Honorable Mention in Dry Futures, an ideas competition focused on solutions for the California drought. Designer Prentiss Darden paired up with the wastewater…

NASA’s OMEGA Program at a Crossroads

Biofuels are my passion, but they have had rather bad press, from complaints about displacing food production to the inefficiency of soybeans and the carbon footprint of ethanol. Microalgae have a low profile…

Natural vs. Synthetic Flocculents

Synthetic polymers used in water/wastewater treatment, and in some instances algae flocculation, are made from monomers obtained from the fractional distillation of oilfield hydrocarbons at oil refineries. The problem with these monomers…

AIM Interview: Dr. John Benemann

As pioneers go, in the modern business of algae biofuels and co-products, possibly no one has built a longer record of accomplishment than Dr. John Benemann. Involved in algae biofuels and…
