HKNIC - Solid waste

Solid waste
Burning fuels, either fossil fuels or biomass, produces considerable quantities of ash and end-products associated with the sulphur that is present in the fuel. These products are classified as solid waste if they cannot find any use. In comparison, nuclear power and most forms of renewable energy produce a much smaller quantity of solid matters that are classified as waste. Although the solid waste from nuclear power generation is radioactive, the radioactivity will decrease, albeit very slowly, with time. The handling of this material is discussed in Managing Spent Fuel and Managing Nuclear Waste.
