ISO/TC 275 - Sludge recovery, recycling, treatment and disposal

This document describes good practices for the incineration and other organic matter treatment by thermal processes of sludges. Thermal conditioning is excluded. This document applies to sludges specifically derived from: — storm water handling; — night soil; — urban wastewater collecting systems; — urban wastewater treatment plants; — treating industrial wastewater similar to urban wastewater. It includes all sludge that may have similar environmental and/or health impacts but excludes hazardous sludge from industry and dredged sludge.

This document provides guidance on the conditions of beneficial use of biosolids produced from industrial and municipal sludge and municipal biosolids derived products (e.g. composts, growing media) in the production of food and feed crops, energy crops, forestry crops and for the remediation of disturbed sites. This document applies to biosolids for land application and includes biosolids from wastewater treatment (municipal, industrial and private onsite systems). This document does not apply to hazardous sludge that originates from wastewater which, due to its nature, physical, chemical or infectious properties, is potentially hazardous to human health and/or the environment during use, handling, storage or transportation and which requires special disposal techniques to eliminate or reduce the hazard. This document includes: — general guidelines for the land application of biosolids and biosolids derived products; — specific guidelines for the land application of biosolids and biosolids derived products for food and feed crop production and for non?food and non?feed crop production (e.g. horticulture, fibre for bio?mass, silviculture, etc.); and — specific guidelines for the land application of biosolids and biosolids derived products for other beneficial uses (e.g. land reclamation or rehabilitation).
