Biotechnology developed in New Zealand by LanzaTech is to be installed at ArcelorMittal’s steel mill in Ghent, Belgium, to capture carbon monoxide and convert it into ethanol.  Read more »

Hydrogen from Wastewater

Written by , on February 25, 2015

Researchers from the Universitat Autònoma de Barcelona have reported that they have developed an efficient way to obtain electrical energy and hydrogen in a wastewater treatment process. The system uses bacteria which consume the organic material and generate electricity which is used to produce hydrogen.   Read more »

New Process Triples Biogas Production from Waste

Written by , on November 5, 2014

Researchers in Spain have developed the new “BiogàsPlus” technology which increases the production of biogas by 200% with a controlled introduction of iron oxide nanoparticles to the process of organic waste treatment.  Read more »

Energy Dense “Biobattery” Runs on Sugar

Written by , on March 18, 2014

A research team at Virginia Tech university, led by Professor Y.H. Percival Zhang, has developed a sugar-powered fuel cell that stores ten times as much energy as the equivalent-size lithium-ion battery. The new sugar-powered cell has an energy density an order of magnitude higher than previous “”biobatteries” – allowing it to run longer before needing to […]  Read more »

Discovery Could Eliminate Need for Nitrogen Fertilisers

Written by , on July 26, 2013

Professor Edward Cocking, at the University of Nottingham, has developed a process which enables all crops to take nitrogen from the air rather than from environmentally damaging fertilisers. Nitrogen fixation is the process by which plants convert nitrogen is ammonia which is vital for plants to survive and grow.The vast majority of plants obtain their […]  Read more »

Water Treatment Using Apple and Tomato Peel

Written by , on July 26, 2013

Tomato is the second most consumed vegetable in the world, with approximately 30% consumed as processed products. The disposal of the tomato skin and its other fibrous materials is a waste for many food processing industries. Ramakrishna Mallampati, at the National University of Singapore, has studied the structure of the tomato peel to assess its […]  Read more »

Batteries from Wood and Rice

Written by , on July 17, 2013

Wood Lithium-based rechargeable batteries are expensive and lithum is relatively scarce. On the other hand, sodium is abundant and cheap and can be used in place of lithium in batteries. The problem is that sodium ions are many times larger than lithium ones and they gradually damage a battery's anode as they diffuse during charging […]  Read more »
