Characterisation of residues from industrial processes and waste treatment - Final Report
Abstract:
Good quality waste characterisation data are fundamental to Defra's policies and strategies to manage environmental challenges, yet the UK dataset for the new generation of treated wastes was poor. This project aimed to fill some of the gaps in understanding the characteristics of residues from the treatment of municipal solid waste and industrial process wastes.
The overall objectives were to:
- Provide "state of the art" data and information on the characteristics of pre/post-treatment wastes
- Provide a UK-wide data resource focusing on composition and leachability (through UK support to leachXS)
- Review the UK landfill waste acceptance criteria for monolithic wastes.
A consistent approach to the sampling and testing of the residues has been used as advocated in the Environment Agency's sampling and testing guidance (2005). This includes the use of scenario-specific sampling plans to enable future replication of testing and the full characterisation toolbox (e.g. composition, leachability, biodegradability testing). The datasets have been imported into leachXS and the benefits of this data management and expert tool to technical specialists and policy developers can be seen, for example the rapid comparison of the characteristics of the new generation of treatment residues with more traditional waste streams.
The nitrogen fertilizer value of most organic wastes is much lower than that of sewage sludge. More organic waste would therefore be needed to be applied to soils to provide the same fertiliser value as sewage sludge. The partially stabilized organic wastes have a high requirement for oxygen. There is a risk that the soil system would be unable to sustain the oxygen needed for respiration by the in situ microbial population and so adverse anoxic conditions are likely to exist in the soil.
