To dispose of waste materials by burying them Landfills are designed to minimize environmental impact.

A facility that burns waste to generate energy This process reduces the volume of waste and produces electricity.

A technology that uses plasma to convert organic materials into syngas Syngas can be used as a fuel or for chemical production.

A mixture of hydrogen, carbon monoxide, and sometimes carbon dioxide. It can be produced from various feedstocks and is used in energy production and chemical synthesis.

Waste that is discarded and no longer useful. Effective waste management is crucial for environmental protection and public health.

Pollutants that originate from a single, identifiable source. Examples include wastewater discharge from factories or sewage treatment plants.
