Treatment in urbanized areas is typically handled by centralized treatment systems. Alternative systems may use composting processes or processes that separate solid materials by settlement and then convert soluble contaminants into biological sludge and into gases such as carbon dioxide or methane .

This method is useful for the disposal of both municipal solid waste and solid residue from wastewater treatment. This process reduces the volume of solid waste by 80 to 95 percent. [ 42 ] Incineration and other high-temperature waste treatment systems are sometimes described as " thermal treatment ".
Landfills waste are categorized by either being hazardous, non-hazardous or inert waste. In order for a landfill design to be considered it must abide by the following requirements: final landforms profile, site capacity, settlement, waste density, materials requirements and drainage.
