Cleanup methods refer to various techniques used to remove contaminants or waste from an environment. Common methods include manual cleaning, where workers physically remove debris, and chemical cleaning, which uses substances to dissolve or neutralize pollutants. Other methods involve bioremediation, where microorganisms break down harmful materials, and vacuum extraction, which removes liquids or gases from soil or water. Each cleanup method has its advantages and limitations, depending on the type of contamination and the environment. For instance, thermal treatment can effectively eliminate hazardous waste but may not be suitable for all materials. Choosing the right method is crucial for effective and safe cleanup.
