Traditionally, plastic recycling processes involve using a lot of water. In order to avoid this waste, researchers developed a new green technology that doesn't require liquids, and has the capacity to process materials such as styrofoam, polystyrene and ABS using the same type of customizable machinery.
The 45% fall in oil prices is being portrayed as a big blow to clean energy deployment. In fact, its impact will vary by sector and region, but will be modest in major electricity markets where renewables compete with gas and coal, and benefit from stable policy support.
An aircraft with a parallel hybrid engine - the first ever to be able to recharge its batteries in flight - has been successfully tested in the UK, an important early step towards cleaner, low-carbon air travel.
A team from the University of Arizona and eight southwestern electric utility companies have built a pioneering web portal that provides insight into renewable energy sources and how they contribute to the region's electricity grid.
A global fleet of composite planes could reduce carbon emissions by up to 15 per cent, but the lighter planes alone will not enable the aviation industry to meet its emissions targets, according to new research.
Windows allow brilliant natural light to stream into homes and buildings. Along with light comes heat that, in warm weather, we often counter with energy-consuming air conditioning. Now scientists are developing a new kind of 'smart window' that can block out heat when the outside temperatures rise.
Cutting the environmental costs of aero engine parts manufacturing, increasing freedom in their design and reducing fuel consumption and contaminating gas emissions are some of the benefits resulting from applying modern additive manufacturing techniques to the aircraft industry.
The transport sector is still generating excessive greenhouse gas emissions and harmful levels of air pollution and noise, according to the latest edition of the European Environment Agency's annual report on environment and transport.
