Standards New Zealand is consulting with key stakeholders to form the New Zealand view about whether a new field of activity should go ahead at the International Organization for Standardization (ISO), Sludge recovery, recycling, treatment, and disposal.
The proposed new field of activity involves standardisation of the methods to characterise, categorise, prepare, treat, recycle, and manage sludge and products for urban wastewater collection systems, night soil, storm water handling, water supply treatment plants, and wastewater treatment plants for urban and similar industrial waters.
The proposed new field of activity includes all sludge that may have similar environmental and/or health impacts. Standardisation of measurement methods to characterise and categorise encompasses sampling methods, physical, chemical and microbiological parameters analysis, preparation of sludge, and physical behaviour of sludge – all required to characterise sludge to help decision-making on the choice of the treatment procedures and of the use and disposal of sludge.
Hazardous sludge from industry and dredged sludge already covered by ISO Technical committee 190, Soil quality, is excluded.
