In many countries waste was divided into two categories, hazardous and nonhazardous, and separate regulations were developed for their disposal.

Landfills were designed and operated in a manner that minimized risks to public health and the environment.

The sources of solid waste include residential, commercial, institutional, and industrial activities.

Certain types of wastes that cause immediate danger to exposed individuals or environments are classified as hazardous; these are discussed in the article hazardous-waste management.A technological approach to solid-waste management began to develop in the latter part of the 19th century.Watertight garbage cans were first introduced in the United States, and sturdier vehicles were used to collect and transport wastes.However, because C&D waste is inert and nonhazardous, it is usually disposed of in municipal sanitary landfills.Another type of solid waste, perhaps the fastest-growing component in many developed countries, is electronic waste, or e-waste, which includes discarded computer equipment, televisions, telephones, and a variety of other electronic devices. Lead, mercury, and cadmium are among the materials of concern in electronic devices, and governmental policies may be required to regulate their recycling and disposal.Near the end of the 14th century, scavengers were given the task of carting waste to dumps outside city walls.But this was not the case in smaller towns, where most people still threw waste into the streets.Waste disposal methods were still very crude, however.Garbage collected in Philadelphia, for example, was simply dumped into the Delaware River downstream from the city.Garbage is highly putrescible or decomposable, whereas rubbish is not.Trash is rubbish that includes bulky items such as old refrigerators, couches, or large tree stumps. Construction and demolition (C&D) waste (or debris) is a significant component of total solid waste quantities (about 20 percent in the United States), although it is not considered to be part of the MSW stream.
