Solid waste from the energy sector is limited to waste that results directly from the
normal functioning of that sector. Included are waste from coal and lignite mining and
upgrading (tails); waste from oil and gas extraction and from refineries; combustion
waste from thermal power stations (bottom ash, flying ash, slug); waste from the
incineration of industrial and municipal waste, when these are used as a fuel in power
stations; and waste from air pollution abatement technologies (sludge from scrubbers,
spent catalysts). Non-regular waste such as decommissioned oil/gas rigs, power
stations, refineries and other machinery should be reported separately, as these are
exceptional events requiring special disposal measures. For the purpose of this
indicator, radioactive waste and (scrapped) road vehicles, railway wagons and sea-
going vessels

• Recycling or reuse of waste;
• Incineration in incinerators fitted with appropriate filters, etc., to remove
noxious emissions;
• Solidification, so as to prevent landslide; and
• Disposal in secured and lined landfill sites and other sites where measures are
in place to avoid runoff and uncontrolled combustion.
