ORNL story tips: Stealthy air leak detection, carbon to chemicals and recycling goes large
Researchers at Aalto University have discovered that electrodes in lithium batteries containing cobalt can be reused as is after being newly saturated with lithium. In comparison to traditional recycling, which typically extracts metals from crushed batteries by melting or dissolving them, the new process saves valuable raw materials, and likely also energy.
Plastics are ubiquitous, but they’re not practical. Less than 10% are recycled, and the other ~8 billion tons are creating a pollution crisis. A Berkeley Lab team is determined to change that. A new analysis shows producing and recycling their game-changing new plastic could be easy and cheap enough to leave old plastics in the dust.
In a new study, researchers at Aalto University have investigated the environmental effects of a hydrometallurgical recycling process for electric car batteries. The carbon footprint of the raw material obtained by the recycling process studied is 38% smaller than that of the virgin raw material. The difference is even greater if copper and aluminium recovered during mechanical pre-treatment are included.
Scientists at the U.S. Department of Energy’s Ames Laboratory and their partners from Clemson University have discovered a green, low-energy process to break down polystyrene, a type of plastic that is widely used in foam packaging materials, disposable food containers, cutlery, and many other applications.
Single-use plastic bags continue to pose a global environmental challenge, as their composition and form makes them difficult to recycle, and hundreds of years are required for them to degrade fully in the environment. While reusabable shopping bags offer an earth-friendly option, what if plastic bags could be recycled or placed in our composts?
Not all plastics are created equally – from milk jugs and soda bottles, which are readily recyclable, to multi-layered packaging that increases shelf life and requires less material but is less recyclable – the challenge is for researchers to design a process that allows more of the plastics we use in our everyday lives to end up in our recycle bins rather than the local landfill.
Composting services provide many benefits in urban areas
Oak Ridge National Laboratory and Department of Energy officials dedicated the launch of two clean energy research initiatives that focus on the recycling and recovery of advanced manufacturing materials and on connected and autonomous vehicle technologies.
Researchers report in ACS Central Science a way to recycle used polyurethanes into equivalent or even higher-value items.
Researchers are turning waste denim into acoustic insulation materials
Scientists from Woods Hole Oceanographic Institution reveal how microorganisms could survive in rocks nestled thousands of feet beneath the ocean floor in the lower oceanic crust.
Four of the largest potato producers in Australia want to convert 100% of their potato waste into commercial benefit.
Supplies of the cobalt are adequate in the short term, but shortages could develop down the road if refining and recycling aren’t ramped up or made more efficient, according to research published in ACS’ Environmental Science & Technology.
For years, China processed more than half of the world’s plastic recycling. Then, in 2018, it stopped. Things have gotten messy since then.
Researchers reporting in ACS Central Science have developed a catalyst that can transform polyethylene –– the type of plastic used to make grocery bags –– into high-quality liquid products, such as motor oils and waxes.
