Potential impact of draft proposals to revise the EC Directive controlling sewage-sludge applications to land
2002
Towers, W. | Paterson, E. | Coull, M.C.
The EC Directive which controls the application of sewage sludge to agricultural land, in particular, the reduction in permitted concentrations of heavy metals in sludge and sludge-amended soils, is being reviewed by the European Commission. The implications for sludge recycling in Scotland are examined, and it is estimated that the available land bank would be reduced to about 50% of its present area. In addition, the land area which is required would have to significantly increase because of the proposed lower application rates. The scenarios cast doubt on the long-term viability of the sludge-recycling option in Scotland.
