Waste-to-energy is the process of using waste to generate energy. This can be done through incineration, pyrolysis, or gasification.

Waste reduction is the process of reducing the amount of waste produced. This can be done through source reduction, recycling, or composting.

Incineration is the process of burning waste at high temperatures. This is a common method of waste disposal, but it can also produce harmful air pollution.

Pyrolysis is the process of breaking down organic waste into a combustible gas. This gas can then be used to generate energy.

Gasification is the process of converting organic waste into a synthetic gas. This gas can then be used to generate energy.

An injection well is a deep underground well used to dispose of waste. This method of waste disposal is often used for hazardous waste.

Ocean dumping is the process of disposing of waste in the ocean. This method of waste disposal is now banned in most countries.

Land spreading is the process of disposing of waste by scattering it over a large area. This method of waste disposal is often used for agricultural waste.

Landfilling is the process of disposing of waste by burying it in the ground. This is the most common method of waste disposal.
