Non-recyclable waste refers to materials that cannot be processed and reused in recycling systems. This type of waste often includes items like certain plastics, polystyrene foam, and contaminated materials that cannot be cleaned or sorted effectively. When disposed of, non-recyclable waste typically ends up in landfills, where it can take years to decompose. Proper management of non-recyclable waste is essential for reducing environmental impact. Many communities implement waste separation programs to help residents identify which items are recyclable and which are not. Understanding the difference can lead to more responsible disposal practices and a cleaner environment for everyone.
