Environmentally-friendly

It’s a given that we will one day be discarding our present laptop computers. It’s also a given that e-waste is currently a huge problem, that looks like it’s only going to get worse. While most of the materials in a laptop can be recycled, all of those pieces of glass, metal, plastic and circuitry are stuck together pretty tight, and require a lot of time and effort to separate. What is needed are laptops that are designed to be taken apart, for easy recycling – that’s why a group of graduate students from Stanford University made one.  Read More

It’s always a bummer when you take something like a computer or TV out of its box, and realize that all that Styrofoam is just going to end up in the landfill. Although it can be recycled, due to transport costs and lack of market demand, most cities don’t do so. There’s also the fact that it’s made from petroleum – so it's a long way from being sustainable. Fortunately, though, an international team of scientists has recently developed a biodegradable foam. It’s made from clay and casein, which is a naturally-occurring protein in cow’s milk.  Read More

In a collaborative study on sustainable building materials, researchers from Spain’s University of Seville and Glasgow’s University of Strathclyde have created bricks that contain sheep’s wool and a polymer derived from seaweed. Clay-based soils were provided by Scottish brick manufacturers, while the wool came from Scotland's textile industry, which produces more of the stuff than it can use. The polymer was an alginate, which occurs naturally in the cell walls of seaweed. Mixed together, the three substances resulted in bricks that were reportedly 37 percent stronger than regular unfired bricks.  Read More

Because they produce no exhaust gases in operation electric vehicles (EVs) are seen as the eco-friendly alternative to conventional gas-fueled cars. While zero-local emissions is clearly a big plus, other factors contributing to the overall environmental impact of EVs are often overlooked – namely the manufacture, usage and disposal of the batteries used to store the electrical energy and the sources of power used to charge them. Now, for the first time, a team of scientists from the Swiss Federal Laboratories for Materials Testing and Research (or EMPA) have made a detailed life cycle assessment or ecobalance of the type of lithium-ion batteries most frequently used in EVs, to see if they really are as environmentally friendly as their manufacturers would have us believe.  Read More

NEC has announced the development of a new biomass-based plastic produced by bonding non-edible cellulose with cardanol, a primary component of cashew nut shells. The new bioplastic is said to achieve a level of durability that makes it suitable for use in electronic equipment and boasts a high plant composition ratio of more than 70 per cent.  Read More

If small is beautiful, then the 320 square-foot EDGE house from Wisconsin’s Revelations Architects is absolutely gorgeous. EDGE stands for Experimental Dwelling for a Greener Environment, and true to that acronym, the award-winning little modular home includes Earth-friendly features such as rainwater collection, geothermal heating and cooling, air-to-air heat recovery, passive solar windows, and insulated exterior shutter doors that minimize nighttime heat loss. Making the most of every square inch of interior space, the house has multi-functional transformable furniture, plus two overhead bedrooms. It's also made for easy construction and relocation, to the point that the prototype has been assembled, taken apart and moved three times in six months.  Read More

Mosquitoes could be having a tough time of it before too long. First, scientists announced an experimental new technology that utilizes gene-silencing nanoparticles to keep mosquito larvae from fully developing their protective exoskeletons. This leaves them much more vulnerable to insecticides, once they become adults. Now we have word of another study, in which researchers have identified a natural, environmentally-friendly chemical compound that causes female skitters to go elsewhere to lay their eggs.  Read More

Thought there wasn't much you could do with the design of a pizza box? Wrong. Environmentally Conscious Organization, Inc., (E. C. O.) has come up with what it calls the "Green Box" – a pizza box made from recycled cardboard with a perforated lid that you can easily turn it into four plates and a base that becomes a storage container for leftovers.  Read More

Windows that change their tint are not new, but this window by RavenBrick does so without any energy use required. The RavenWindow changes its transparency depending on the temperature, so basically if it's hot outside less heat passes through it and if it's cold outside then it becomes more transparent, allowing in more heat from the sun. The implications are obvious – savings on your energy bill as a result of reduced use of your heater or air conditioner. With "America's Greenest Building" commissioning the first commercial installation of the product, it's bound to have a bright future.  Read More
