Biogas

Aquaponics operations combine aquaculture and hydroponics, with nutrient-rich water from the former being used to fertilize plants in the latter. Soon, such systems could also be powered by methane biogas derived from their own fish feces.

New Holland Agriculture has announced a new tractor designed to run on fuel created on-site using cow manure. The T7 Methane Power LNG offers the same power and torque as a diesel tractor, but it's part of a system that can greatly reduce emissions.

Israeli company HomeBiogas has just introduced a third generation model it says produces 30 percent more clean fuel than its previous system, along with fertilizer to give your plant life a boost.

They may give us an almost endless supply of eggs and nuggets, but industrial chicken farming comes with a tradeoff: it produces a lot of poop. To turn a con into a pro, researchers have developed a process that mixes chicken manure with an invasive weed to create a feedstock for making biofuel.

Last month, executives at Lockheed Martin’s Owego, New York plant cut the ribbon on a new self-sustaining bioenergy system that is helping power the facility, converting 3,560 tons of waste per year into clean electricity.

There’s nothing like a good shit show to bring in the tourists. The Shit Museum, or Museo della Merda, is a research and data-collection institute set in a medieval castle in Northern Italy that houses documents and information on excrement in culture, technology, science and history.

​An Israeli startup has launched a crowdfunding campaign to bring a backyard biogas converter to both developed and developing countries. The HomeBiogas digester can turn kitchen leftovers and livestock manure into natural liquid fertilizer and clean gas for cooking, lighting and water heating.

By now, most people have at least a passing knowledge of biodiesel. While it's a good choice for people with diesel-powered vehicles, those of us with gas-burning cars haven't been able to get in on the action ... although that may be about to change.

Award winning architect John Lin and his colleagues at Hong Kong University are designing a traditional rural China for the future!

Fraunhofer researchers have developed a pilot plant that ferments the waste from wholesale fruit and veg markets, cafeterias and canteens to make methane, which can be used to power vehicles.

The Loowatt system allows human waste to be extracted from special toilets, and placed in an anaerobic digester to create biogas and fertilizer.

VTT is field testing a solid oxide fuel cell system that may someday provide grid electricity from natural or bio- gas.
