This CEN Report describes good practice for the use of sludges in agriculture (where national regulations permit). It is applicable to all of the sludges described in the scope of CEN/TC 308 (and any of the forms in which they may be presented - liquid, dewatered, dried, composted, etc.) i.e. sludges from :
-- storm water handling ;
-- night soil ;
-- urban wastewater collecting systems ;
-- urban wastewater treatment plants ;
-- treating industrial wastewater similar to urban wastewater (as defined in Directive 91/271/EC) ;
-- water supply treatment plants ;
-- but excluding hazardous sludges from industry.
Such sludges can be used on land as a source of plant nutrients, and/or soil improver, and/or liming material for crop production. Despite differences in the statutory controls between sewage sludge and other sludges, the use of all types of sludge should follow good practice to maximise benefits for the crops or soils, to minimise potential risks of environmental contamination and adverse impacts on plant, animal and human health, and to ensure sustainability and cost-effectiveness.
Sludge producers should be aware that if a sludge is used as a fertilising or liming material, national or EC fertiliser or liming regulations may apply.
The document assumes that an evaluation has already been made and a decision taken that use of sludge within a land spreading policy is the best option for the sludge in question.
NOTE For evaluation and decisions for use of sludges, other documents are currently in development (see CR 13174).
Many countries and/or local administrations have regulations and/or standards and/or codes of practice applicable to the use of some of the types of sludge that are within the scope of this report, however it cannot, and does not, attempt to summarise or take account of these regulations, etc. because of their very wide range. It is thus essential that this report is read in the context of the conditions that prevail locally.
