Electronic waste (or e-waste) describes discarded electrical or electronic devices. It is also commonly known as waste electrical and electronic equipment (WEEE) or end-of-life (EOL) electronics. [1] Used electronics which are destined for refurbishment, reuse, resale, salvage recycling through material recovery, or disposal are also considered ...
Battery recycling is a recycling activity that aims to reduce the number of batteries being disposed as municipal solid waste.Batteries contain a number of heavy metals and toxic chemicals and disposing of them by the same process as regular household waste has raised concerns over soil contamination and water pollution.

Lithium-rich clays are the third major source of lithium, although they are far less abundant than salt brines and hard-rock ores containing lithium. To be exact, lithium-rich clays make up less than 2% of the world's lithium products. [16] For comparison, brine extraction represents 39% and hard-rock ores represent 59% of the lithium ...
Brine mining is the extraction of useful materials (chemical elements or compounds) which are naturally dissolved in brine.The brine may be seawater, other surface water, groundwater, or hyper-saline solutions from several industries (e.g., textile industries). [1]
The U.S. Environmental Protection Agency (EPA) prohibits disposing of certain materials down drains. [4] Therefore, when hazardous chemical waste is generated in a laboratory setting, it is usually stored on-site in appropriate waste containers, such as triple-rinsed chemical storage containers [5] or carboys, where it is later collected and disposed of in order to meet safety, health, and ...
Furthermore, batteries are globally demanded for containing lithium in regards to manufacturing, the toxic chemicals that lithium produce can negatively impact humans, soils, and marine species. [96] Lithium production increased by 25% between 2000 and 2007 for the use of batteries, and the major sources of lithium are found in brine lake ...
Oxophilicity is the tendency of certain chemical compounds to form oxides by hydrolysis or abstraction of an oxygen atom from another molecule, often from organic compounds. The term is often used to describe metal centers, commonly the early transition metals such as titanium , niobium , and tungsten .
Waste segregation is the division of waste into dry and wet. Dry waste includes wood and related products, metals and glass. Dry waste includes wood and related products, metals and glass. Wet waste typically refers to organic waste usually generated by eating establishments and are heavy in weight due to dampness.
