Refuse dump, also known as a landfill, garbage dump, waste site, or a trash heap, is a designated area where waste materials are discarded. Landfills are constructed to ensure that waste materials do not seep into the soil or pollute water sources. They are also regulated to adhere to guidelines that ensure the safety of people living in the area surrounding the landfills. In many countries around the world, recycling and composting have become popular alternatives to reduce the amount of waste sent to refuse dumps. These methods help reduce the environmental impact of refuse dumps and promote a sustainable future.
