Circular Economy 

TL;DR: A special session addressing issues of sustainable solutions and remarkable practices in circular economy focusing materials downstream was held at the 16th International Conference on Waste Management and Technology, where researchers and attendees worldwide were convened to share their experiences and visions as discussed by the authors .

TL;DR: The United Nations Basel Convention on the Transboundary Movement of Hazardous Waste and their disposal is used here as an example to illustrate the challenges and to propose a way forward for anthropogenic circularity as mentioned in this paper .

TL;DR: Li-ion batteries (LIBs) are one of the important alternatives to lessen the dependence on fossil fuel resources as mentioned in this paper , and the global demand for LIBs for portable electrical and electronic equipment (EEE) and EVs have increased significantly, and the amount of spent LIBs is rising logarithmically.

TL;DR: In this paper , the state of the art of mechanochemical technology in the recycling of critical metals from spent lithium-ion batteries was reviewed, and a framework including mechanochemical activation, organic reaction, inorganic reaction, redox reaction, gas-solid reaction, and solid phase synthesis was constructed.
