Shredded and densified boom material, post-consumer plastic, and recycled tires are all go...

During the course of this year’s Gulf Oil Spill, a lot of media attention was paid to the oil booms used to contain and/or absorb the surface slick. While a small percentage of the sausage-shaped tubes of netting were stuffed with unusual materials such as hair, most of them contained oil-absorbent polypropylene. Now that the Deep Horizon well has been capped, the question of what to do with all that oily plastic arises. It turns out that some of it will find its way into Chevrolet Volts.  Read More

Starting next April, a Lufthansa Airbus A321 aircraft making the daily flight between Hamburg and Frankfurt will be running partially on biofuel. The airline will trial the biofuel blend, made of a 50/50 mixture of kerosene and hydrotreated vegetable oil, in one of the plane’s engines for six months. It’s part of the Lufthansa-led burnFAIR project, which is studying the long term effects of sustainable biofuels on aircraft performance. Although the Brazilian airline TAM performed a test flight of a biofuel-powered Airbus A320 last month, Lufthansa claims to be the first airline to conduct a long-term trial using biofuel during flight operations.  Read More

In a new non-toxic process, cinnamon has been used to render nanoparticles from gold salts...

Gold nanoparticles, while showing great promise in fields such as electronics, medical imaging and cancer treatment, nonetheless involve a fairly environmentally-unfriendly production process. Typically, they are produced via liquid chemical methods that involve the use of various noxious substances, such as chlorauric acid. As the field of nanotechnology grows, so do concerns over the consequences for the Earth. University of Missouri scientist Kattesh Katti has found a new method for producing gold nanoparticles that does away with almost all of the toxic agents... and replaces them with cinnamon.  Read More

Cotton has held an important significance for mankind for thousands of years. Not only are all parts of the cotton plant economically useful, but the multitude of uses and processes it can be put to make it America's number one value-added crop. Over the years we have crushed and extruded and woven cotton into many forms, but even today scientists and entrepreneurs are transforming the way we use cotton; from reducing pollution, insulating homes, and cleaning up oil spills to feeding the hungry. Here's a look at seven new companies being championed for their sustainability by Cotton Incorporated.  Read More

Activated carbon cloth could find its way into a variety of filtration applications

Researchers have discovered that activated carbon cloth is very effective at filtering harmful compounds out of air and liquids. The material was first developed in the 1980s, to protect British soldiers from chemical attacks. It is still in use today, in chemical, biological and radiological warfare suits for the military. This recent study, however, indicates that it could have a number of other uses.  Read More

Since announcing the Vac from the sea initiative in June, Electrolux has been busy working with environmental organizations and concerned individuals to collect plastic debris from marine environments around the globe. Now the company has announced the creation of five one-off vacuum cleaner creations manufactured using waste collected from key areas, including Hawaii, the North Sea and the Mediterranean.  Read More

Yi Cui, an Assistant Professor of Material Science and Engineering at Stanford University, has invented quite the water filter. It’s inexpensive, is very resistant to clogging, and uses much less electricity than systems that require the water to be pumped through them. It also kills bacteria, as opposed to just trapping them, which is all that many existing systems do.  Read More

The bauxite residue container pond spill near Kolontar, Hungary

It might sound like fighting fire with fire, but geologist Chen Zhu proposes the application of another industrial waste to the Hungarian bauxite residue spill, with the aim of reducing toxicity via a technique called carbon sequestration. While he says it wouldn't render the residue completely harmless, it would at least minimize the environmental damage.  Read More

The University of Copenhagen's Prof. Matthew Johnson, inventor of the Cleanair system

According to the University of Copenhagen’s Prof. Matthew Johnson, approximately one-sixth of the energy consumed in the world is used for heating, cooling and dehumidifying air in buildings. Because that air accumulates toxins and pathogens, he explains, it must constantly be expelled and replaced with new air that’s drawn in from outside. That new air must then be heated, cooled and/or dehumidified all over again. If only the air already in buildings could be cleaned up and reused, far less energy would be used on continuously conditioning fresh air. That’s why Johnson has invented the Cleanair system.  Read More

The insecticidal protein Cry1Ab has been shown to leach from corn debris into adjacent str...

A new study by Indiana’s University of Notre Dame has revealed that streams across the U.S. Midwest contain insecticides from adjacent fields of genetically engineered corn, even well after harvest. The transgenic maize (GE corn) in question has been engineered to produce the insecticidal protein Cry1Ab. Pollen, leaves and cobs from those plants enter streams bordering on the cornfields, where they are said to release Cry1Ab into the water.  Read More
