Which of the following best describes solid waste?

The definition of solid waste encompasses a range of refuse that is in solid or semisolid form. This includes not just biodegradable materials, but also non-biodegradable items, industrial byproducts, and various other forms of refuse such as organic waste, plastics, metals, and paper. Solid waste can come from various sources, including households, commercial establishments, and industrial operations, and may include items that are recyclable, compostable, or simply discarded without any recourse for re-use or recycling. Understanding solid waste as a broad category allows for more effective waste management practices and policies, ensuring that all types are appropriately classified and handled according to their specific disposal needs.
