Disposing of waste safely depends on the nature and composition of the waste. Disposal methods often determine the type of disposal that is most environmentally and ecologically sound. Generally, wastewater is treated and then recycled for potable uses in wastewater treatment facilities. Flocculants and other heavier-than-water particulates are used to filter the water initially. There are several stages of wastewater treatment until the final product is safe for reuse.
Solid Waste Disposal
Most households are responsible for tons of solid waste that is disposed of in landfills or recycled. Some household solid waste is comprised of remnants from foodstuffs. Recyclable household items like aluminum cans, newspapers, plastics and glass are sorted before they are recycled.
Industrial solid waste requires a completely different aspect than household solid waste and therefore, disposal is more complex. Toxic solids from chemical facilities must be properly stored until final disposal. This may be in a lead lined pond or in drums that will be removed by a licensed industrial waste disposal professional. However, depending on the toxicity levels of the industrial waste, certain types of chemicals and chemical by-products may be disposed of in regulated facilities where highly toxic waste is stored.
