Produced from the treatment of sewage. Biosolids have to comply with EC and UK legal standards and the Safe Sludge Matrix for agricultural use.

Nutrient-rich organic material that are produced from the stabilization of sewage sludge and residential septage that meets specific quality criteria and are suitable for land application.

Biosolids that meet stricter pollutant and pathogen reduction criteria.

Non-exceptional quality biosolids are biosolids that meet specified pollutant and pathogen reduction criteria. Criteria for non-exceptional quality biosolids are less stringent than criteria for exceptional quality biosolids. Note: The term 'Biosolids' can be used to refer to all categories of biosolids collectively, or can be used to ref [..]

Residuals generated by the treatment of sewage, petroleum refining waste and industrial chemical manufacturing wastewater with activated sludge.  See Activated Sludge.

The term used by the Ministry of the Environment to refer to sewage sludge.

The nutrient-rich organic materials resulting from the treatment of sewage sludge.  Biosolids can be safely recycled and applied as fertilizer.

Biosolids are organic materials which can be made from treated wastewater. They can be used to enrich and fertilise soil.

The nutrient-rich organic byproduct material resulting from the treatment of sewage sludge and wastewater.

 – Sewage sludge that has been treated to reduce or eliminate health risks and improve beneficial characteristics. Biosolids are nutrient rich and may be suited to a range of beneficial uses in agricu [..]

A primarily organic solid product produced by wastewater treatment processes that can be beneficially recycled. The word biosolids is replacing the word sludge when referring to treated waste.

A by-product of wastewater treatment sometimes used as a fertilizer.

Nutrient-rich organic materials obtained from wastewater treatment and used beneficially as a fertilizer.

solid materials resulting from wastewater treatment that meet government criteria for beneficial use, such as for fertilizer.

a nutrient-rich organic material resulting from the treatment of wastewater. Biosolids contain nitrogen and phosphorus along with other supplementary nutrients in smaller doses, such as potassium, sulfur, magnesium, calcium, copper and zinc. Soil that is lacking in these substances can be reclaimed with biosolids use. The application of biosolids t [..]

nutrient-rich organic materials derived from wastewater solids (sewage sludge) that have been stabilised through processing.

Residuals generated by the treatment of sewage, petroleum refining waste and industrial chemical manufacturing wastewater with activated sludge. See Activated Sludge.
