Methane

A recent study suggests that the methane gas generated by biodegrading alternatives to tra...

As tons of plastic items continue to take up space in landfills, and the floating Great Pacific Garbage Patch continues to grow, environmentally-conscious consumers are understandably becoming more interested in biodegradable alternatives to traditional plastic. Whether it's because they share these concerns, or are just trying to cash in on an "eco-fad," many companies have responded by producing biodegradable versions of formerly near-eternal plastic products. While biodegradable products are designed to reduce the amount of trash clogging up our waterways and spoiling our parks, at least one scientist believes they may ultimately be doing more harm than good.  Read More

The new biogas plant, sited next to the Didcot sewage works in Oxfordshire, has been offic...

The biomethane project that turns human waste into green gas that we featured in May has now gone live. The project is now converting the treated sewage of 14 million Thames Water customers into clean, green gas and is pumping that gas into people's homes.  Read More

Dry water has been found to have several potential environmentally-friendly uses

You know, I’m pretty sure I remember a Far Side cartoon or something, where someone was selling powdered water – “Just add water!” Well, dry water isn’t quite the same thing. It’s 95 percent liquid water, but that water takes the form of tiny droplets each encased in a tiny globe of silica. The resultant substance is dry and granular. It first came to light in 1968, and was used in cosmetics. More recently, a University of Liverpool research team has been looking into other potential uses for the substance. They have found several, but most interesting is its ability to store gases such as carbon dioxide.  Read More

A novel process uses rocket thrusters to clean up waste water and power treatment plants (...

Rocket engines are generally not thought of as being environmentally-friendly, but thanks to a newly-developed process, we may someday see them neutralizing the emissions from wastewater treatment plants. The same process would also see those plants generating their own power, thus meaning they would be both energy-neutral and emissions-free. Developed by two engineers at Stanford University, the system starts with the formation of nitrous oxide (N2O) and methane gas - something that treatment plants traditionally try to avoid.  Read More

The first joint mission between the European Space Agency (ESA) and NASA that will study the chemical makeup of the martian atmosphere is scheduled for 2016. The ExoMars Trace Gas Orbiter marks an unprecedented alliance between the two agencies for future ventures to Mars and is the first in a planned series of joint missions leading to the return of a sample from the surface of the Red Planet. Scientists worldwide were invited to propose the spacecraft’s instruments and the ESA and NASA have now made their selections.  Read More

The complete BokashiPetCycle Fermenting System

What do you do with your dog or cat poop? Toss it in the garbage? Put it in your compost heap? Hurl it at your noisy neighbors? Well, according to Seattle researcher Lawrence Green, you shouldn’t be doing any of those things. Feces can contain wonderful things like toxoplasma parasites, E. coli, and salmonella bacteria, which can get into the groundwater. In plastic bags in landfills, it generates methane gas and attracts vermin. To that end, Green developed a product called the BokashiPetCycle Fermenting System. It allows you to pickle your pet’s poop, turning it into a harmless plant fertilizer.  Read More

British Gas in the UK has announced a new biogas pilot scheme (Image: butkaj / Flickr, CC ...

It's good to see a national gas company taking the lead in renewable energy. British Gas in the UK has announced a new pilot scheme with Thames Water and Scotia Gas Networks to build a plant that will clean biomethane gas harvested from human waste and inject it back into the grid for use in kitchens and heating.  Read More

If microscopic Martian life is producing the methane, it likely resides far below the surf...

New research has strengthened the possibility that biological life may exist beneath the surface of Mars. Scientists from Imperial College London have shown that the level of methane on the Red Planet can't be explained by meteorites in the atmosphere. This leaves the theory that microorganisms are producing methane gas as a by-product of their metabolic processes as one of the remaining possible explanations.  Read More

Researchers have found that using argon or helium during the nanotube growth process can i...

Researchers at the Honda Research Institute, Purdue University and the University of Louisville have discovered a way to systematically grow carbon nanotubes with either metallic or semiconducting properties, solving a long-standing problem in nanotechnology research and paving the way for the widespread use of nanotubes in electronics.  Read More

The “roulette wheels” created by MIT researchers to show the range of probability of poten...

Research carried out by the MIT's Center for Global Change Science has predicted that global warming will be roughly double previous estimates – and could be even worse than that. While a major 2003 study indicated a median projected increase in earth surface warming of 2.4 degrees Celsius, the new study, which takes into account possible changes in human activities, points to a median probability of surface warming of 5.2 degrees Celsius by 2100 unless drastic action is taken.  Read More
