Producing pure aluminium from ore accounts for as much as 1 per cent of all greenhouse gas emissions worldwide. Recycling is the best way to reduce that carbon footprint - but manufacturers and recycling companies will have to plan carefully to avoid problems with impurities that accumulate in recycled aluminium over time.
Since most foam materials are made of petrochemical plastics, they aren't very climate-friendly. But now an alternative is in sight - a novel foam material produced entirely from wood, which is not harmful to the environment and is also recyclable. In the long term, wood foam could replace conventional products used for thermal insulation, packaging.
A simplified and reliable device should enable hydrogen production at low cost. Researchers were able to perform water electrolysis without using the expensive membrane placed between the electrodes in conventional systems.
UC San Diego's efforts to produce innovative and sustainable solutions to the world's environmental problems have resulted in a partnership with the region's surfing industry to create the world's first algae-based, sustainable surfboard.
Named EVA, the electric taxi is built by TUM CREATE, a collaboration between Nanyang Technological University (NTU Singapore) and one of Europe's top universities, Germany's Technische Universitaet Muenchen (TUM).
The US Congress successfully hears the 'supermajority' consensus on the reality and causes of climate change, according to scientists from several universities. In a paper published in Climatic Change, the scientists suggest looking at business interests, partisan predispositions and political ideology for the hurdles to policy action.
Plug-in hybrids have low fuel consumption, but require more costly parts than cars with a regular combustion engine. During development, the optimal cost balance must be calculated, which has been extremely time consuming to date. Now researchers have developed a new method that dramatically reduces the time needed for these calculations.
Engineers created technology to recover and purify, either seawater or wastewater from households, hotels, hospitals, commercial and industrial facilities, regardless of the content of pollutants and microorganisms in just 2.5 minutes.
