- definitions of 'sludge' (sewage sludge, septic tank sludge and other sludges), 'treatment' (biological, chemical or heat treatment, long-term storage or any other appropriate process so as significantly to reduce its fermentability and the health hazards resulting from its use) and 'use' (spreading of sludge on the soil or any other application of sludge on and in the soil) (Article 2);

It mainly addresses limit values for heavy metals in soil and sludge; treatment of sludge; conditions on the use of sludge in agriculture; sampling and analysis of soil and sludge; and record-keeping for sludge production and use of sludge in agriculture.

* Sewage sludge - sludge from domestic or urban waste treatment plants, septic tanks and similar sewage treatment plants.
