Trash, also known as rubbish, refers to waste materials that are discarded because they are no longer useful or needed. This can include items like food scraps, packaging, old furniture, and broken appliances. Proper disposal of trash is important to maintain a clean environment and prevent pollution. Trash is typically collected by local waste management services and taken to landfills or recycling centers. Landfills are designated areas where waste is buried, while recycling centers process materials like paper, plastic, and metal to be reused. Reducing the amount of trash produced is essential for sustainability and protecting the planet.
