New Zealand fertiliser company Tnue (Total Nutrient Use Efficiency) has opened the country's first low-emissions, controlled-release nitrogen fertiliser manufacturing plant in Taupō. Using a proprietary technology, it applies a thin membrane to each fertiliser granule, which causes nitrogen to be slowly released over about three months, instead of all at once. Tnue co-founder Bruce Smith said the plant marked a significant milestone for New Zealand’s agritech sector and its transition to greater efficiency and lower-emissions farming. It came at a critical moment, with supply line disruptions in the Middle East, and farmers facing heightened uncertainty about the cost and availability of nitrogen. In 2023, Tnue received $1.1 million from the Regional Strategic Partnership Fund to help build the plant. Cleantech company Eko360 holds 63% of Tnue, while New Zealand Green Investment Finance holds a 36.9% stake.
