Abstract:
Most of the waste resulting from energy production in power plants consists of ash and dust. In 2003 the Finnish incineration plants and power plants produced over 1.6 tonnes of ash, from which about 80% is classified as fly ash. More than half of the fly ash comes from the combustion of carbon (743 000 tonnes), and the rest (519 000 tonnes) from wood and peat combustion. The ash volume from wood and peat combustion has nearly doubled over the past ten years, and it is expected to rise further as a result of the increasing utilisation of biofuels. The objective of the present study was to clarify the heavy metal content of the ash produced by 31 energy production plants in eastern Finland. Currently, ash is utilised in road-foundations, in field, earth work and in land filling site constructions, such as for forest fertilising purposes. The legislation on the utilisation of ash has been updated lately. One of the preconditions for utilising ash as a fertiliser is that the ash must be further refined and processed.
