Pyrometallurgy is a high-temperature process that involves smelting lead-acid batteries to recover lead and other valuable metals.

Recycling e-waste aims to extract valuable materials such as precious metals, rare earth elements, and plastics for reuse in new products.

Chemical recycling involves breaking down contaminated plastics into their basic chemical components, which can then be used to create new materials.

Recycling mercury-containing waste aims to minimize the release of mercury into the environment, as it is a highly toxic substance.

Rerefining involves processing used oil to remove contaminants and impurities, allowing it to be reused as a lubricant or fuel.

Hazardous waste incineration aims to destroy hazardous compounds and reduce their toxicity by subjecting them to high temperatures.

Mechanical recycling involves shredding and processing waste tires to produce rubber crumb, which can be used in various applications such as asphalt paving and rubberized products.

Recycling spent nuclear fuel aims to extract valuable materials such as uranium and plutonium, which can be reused in nuclear reactors.

Hydrometallurgy involves using aqueous solutions to dissolve and extract valuable metals from waste batteries.

Hazardous waste landfills are designed to safely store and isolate hazardous waste from the environment, preventing its release into soil, water, and air.

Mechanical recycling involves melting and reshaping waste plastics into new products, such as plastic lumber and park benches.

Recycling waste solvents aims to extract and reuse valuable solvents, reducing the need for virgin solvent production.

Neutralization involves adding a base to waste acids to neutralize their acidity, converting them into less harmful substances.

Recycling waste pesticides focuses on safe and environmentally sound disposal methods to prevent their harmful effects on human health and the environment.

Incineration is a common method for recycling waste pharmaceuticals, involving high-temperature combustion to destroy harmful compounds and reduce their toxicity.
