Recycling hazardous waste aims to extract valuable materials from the waste, such as metals, solvents, and chemicals, which can then be reused or sold for further use.

Landfilling is a method of disposing hazardous waste, not recycling it. Incineration, pyrolysis, and hydrometallurgy are all processes used to recycle hazardous waste.

Recycling hazardous waste offers multiple benefits, including reducing the need for raw materials, conserving energy, and reducing greenhouse gas emissions.

Recycling hazardous waste faces several challenges, including high cost of recycling processes, lack of infrastructure for recycling, and limited market for recycled materials.

Incineration, pyrolysis, and gasification are all processes that convert hazardous waste into energy.

Reusing hazardous waste involves finding new applications for the waste, such as using spent solvents as cleaning agents, repurposing empty hazardous waste containers, and using hazardous waste as fuel in industrial processes.

Reuse in hazardous waste management aims to extend the lifespan of hazardous materials by finding new applications for them, thereby reducing the need for their disposal and minimizing their environmental impact.

Reusing hazardous waste offers several benefits, including reducing the amount of hazardous waste generated, conserving resources, and reducing the need for raw materials. It does not increase the cost of waste management.

Reusing hazardous waste faces several challenges, including lack of awareness about reuse opportunities, limited market for reused hazardous materials, and high cost of reuse processes.

All of the options provided are examples of successful reuse programs for hazardous waste.

Recovery is the process of extracting valuable materials from hazardous waste, such as metals, solvents, and chemicals, which can then be reused or sold for further use.

Landfilling is a method of disposing hazardous waste, not recovering materials from it. Incineration, pyrolysis, and hydrometallurgy are all processes used to recover materials from hazardous waste.

Recovering materials from hazardous waste offers multiple benefits, including reducing the amount of hazardous waste generated, conserving energy, and reducing greenhouse gas emissions.

Recovering materials from hazardous waste faces several challenges, including high cost of recovery processes, lack of infrastructure for recovery, and limited market for recovered materials.

Treatment is the process of converting hazardous waste into a less hazardous or non-hazardous form, making it safer for disposal or reuse.
