The viability, feasibility, and environmental effects from using New Zealand sourced phosphate

New Zealand has accessible, on-shore sources of phosphate, finds this report.

There are known phosphate deposits in Clarendon, Otago (containing at least 1.6Mt of phosphate ore) and in North Canterbury and Kaikoura (containing a potential combined 10-–20 Mt). There are also likely deposits in South Canterbury and Waitaki.

The carbon footprint for domestically sourced phosphorus would be approximately half that of imported material.

The quarrying process for phosphate rock has similar environmental effects to that of limestone.
