Solid waste disposal is a major challenge for governments. The efficient, effective collection of waste and recycling is a very big job. Government isn't the only entity working on waste. Companies big and small work for, compete with, or supplement government-provided services.
Like most public issues, the key is planning. Siting a landfill is a costly undertaking. Proper monitoring and maintenance are also a significant investment. As long as people create waste, communities will have to plan for its management and disposal.
