The Wellington City Council is seeking information from the market on potential solutions for the beneficial reuse of biosolids that will be produced by the new Sludge Minimisation Facility, currently due for completion in 2026.

The SMF is expected to produce Grade A, thermally dried, biosolids at a rate of approximately 5 – 6.5 metric tonnes per day.

The purpose of this RFI is to:

- Gain insights into innovative, sustainable and commercially viable options for the reuse or beneficial application of biosolids

- Understand the range of solutions and end use applications currently available or under development in New Zealand.

- Assess market capability, environmental outcomes, and potential partnerships that could support WCC’s long-term strategy for sustainable waste management.
