If you want to read more about the specific indicators/requirements regarding this topic [Criterion 2.9: Responsible disposal of Biosolids] and other information relating to the ‘Alignment’ and draft ASC Farm Standard (including specific questions part of the Stakeholder Survey), please click here.

These issues are also currently addressed within the existing ASC species Standards: all of ASC’s 11-species Standards can be found here.

Why is this an issue?

“Biosolids” (or sludge) are a mixture of organic waste and sediment produced or accumulated through farming activities. Biosolids discharged into natural water bodies can cause excessive plant and algal growth (eutrophication), restrict light penetration, cover plants and habitat and cause general shallowing of water bodies. Unregulated disposal of biosolids on land can cause soil eutrophication or salinisation and affect groundwater.

This is why the proposed ASC Farm Standard aims to ensure responsible handling and disposal of biosolids generated through farming activities, including by implementing a site-specific Biosolids Management Plan (BMP) and ensuring recycling of nutrients in regulated facilities where possible.
