A landfill is a designated area where waste materials are disposed of by burying them in the ground. This method helps manage solid waste, preventing it from accumulating in public spaces. Landfills are engineered to minimize environmental impact, often featuring liners and systems to control leachate and gas emissions. Landfills can vary in size and type, including municipal landfills for household waste and industrial landfills for commercial waste. Proper management is essential to ensure that they do not harm the surrounding environment or public health. Over time, landfills can be capped and repurposed for parks or other uses once they are closed.
