Niron Magnetics has secured a $150 million loan from the Shakopee Mdewakanton Sioux Community and a conditional $150 million, 20‑year direct loan commitment from the US Department of War’s Office of Strategic Capital to build its first full‑scale iron nitride magnet plant in Sartell, Minnesota. The facility, targeting start-up in 2027, will manufacture rare-earth-free iron nitride permanent magnets, aiming to establish a domestic supply for defence and other critical industries. For materials and mining suppliers, the project signals growing demand for iron-based magnet feedstocks and equipment for end-to-end magnet manufacturing lines.

Hertha Metals has produced 99.95% purity (3N5) magnet-grade iron at its demonstration-scale FLEXHERS (flexible fuel hydrogen electric reduction smelting) plant in Conroe, Texas, using fully domestic iron ore and natural gas. The Houston startup says it is the first US producer to meet top rare earth magnet makers’ iron specifications with entirely domestic inputs, addressing a material that currently is almost wholly imported. With US defence manufacturers facing a 1 January 2027 deadline to cut Chinese-origin magnet content, Hertha plans its next Chalyx facility to supply high-purity iron for NdFeB magnet producers.

Grayson has secured ISO 14068 carbon neutrality certification, moving from PAS 2060 to the more demanding international standard that requires quantified emission reductions and independently verified offsets. The company has invested in on-site solar generation, battery storage and lower-carbon logistics, and developed site products such as the recycled aluminium G Board mortar board, designed to replace multiple timber boards over a bricklayer’s career and remain fully recyclable. Building on its earlier Zero Waste to Landfill status, Grayson is among the first UK construction suppliers to meet ISO 14068, giving contractors stronger assurance on embodied carbon claims.
