Australian Architect Stephen Sainsbury has spent decades researching materials to reduce environmental impact. This has culminated in the development of the Ecoshelta prefabricated modular building system. Based on an extensive evaluation of the environmental impact of building materials and other factors, the Ecoshelta Pods are constructed using a combination of eco-friendly timber, a composite panel roof, the latest wall and floor technologies and marine grade structural aluminum alloy.
As electronic devices are becoming outdated at an increasingly fast pace, e-waste continues to be a huge problem.
That's why scientists from the University of Wisconsin-Madison have
started producing "wooden" semiconductor chips that could almost
entirely biodegrade once left in a landfill. As an added bonus, the
chips are also flexible, making them prime candidates for use in
In tropical countries such as the Philippines, there are plenty of rice
husks ... and also plenty of termites. A group of engineering students
from the University of California, Riverside, recently decided to use
the former to address the latter, by creating termite-resistant
particleboard from rice husks.
Boeing is at it again, continuing its on-going ecoDemonstrator test program by ramping up a series of flight tests with a modified 757 airliner. The lengthy tests will assess new methods to advance efficiency, cut noise and lower carbon emissions.
If you're trying to save power, you generally don't leave your lights on all night. With a few exceptions
, however, that's what cities do with their streetlights. That's why some groups have developed streetlights with built-in solar panels
. A Spanish team is now taking things a step farther, with a stand-alone streetlight that runs off of both solar and wind power.
A Mexican startup Ak Inovex has developed a new method of recycling plastic that does away with water and only consumes half the energy of previous systems. At the same time, it produces plastic pellets of equal or better quality, resulting in an environmentally friendlier process that also promises to be significantly cheaper.
The sporty Mazda Miata may not be at the top of many "green car" lists, but the 2016 model
will nonetheless be the first vehicle to incorporate parts made from a new bioplastic developed by the automaker. The plastic is based on plant-derived materials instead of petroleum, and doesn't need to be painted.
While we hear a lot about the wonders of materials like graphene and carbon nanotubes, nanofibrillated cellulose (aka: Cellulose NanoFibrils, or CNF) also shows a lot of promise. A type of "nanocellulose
", it can be used to produce composite materials that are strong, light, electrically-conductive and oxygen-impervious. Additionally, it uses an existing waste product as its feedstock. Unfortunately its production process is fairly energy-intensive, limiting its widespread use. Thanks to a new technique, however, that may soon no longer be the case.
Almost a year ago, Boeing announced that it was looking into running airliners on a mixture of jet fuel and "green diesel"
– the latter of which is made from vegetable oils, waste cooking oil and waste animal fats. Yesterday in Seattle the corporation followed through on that plan, flying its ecoDemonstrator 787
flight test airplane on the fuel blend.
One man's waste is another's man's bus fuel, so the saying might now go. Indeed, next time people in the UK go for a number two, they could be powering the number two bus. Geneco's new Bio-Bus is powered by gas generated via the treatment of sewage and food waste.
