1. Question
Consider the following statements regarding landfills:
1. Landfill bioreactors are advanced systems designed to accelerate waste decomposition and methane recovery.
2. Leachate formation in landfills is solely dependent on the amount of rainfall.
3. Sanitary landfills are engineered to prevent environmental contamination through measures such as liners and leachate collection systems.
4. Landfill mining can help recover valuable resources, including metals and energy, while reducing the total waste volume.
Which of the statements given above is/are correct?CorrectAnswer:
