Phosphorus

What it is

Elemental (white) phosphorus is produced from phosphate rock and used in detergents, food additives, lithium-iron-phosphate batteries, and chemical synthesis.

Why it matters

Production is concentrated in Kazakhstan, Vietnam, and China; the EU imports almost all of its supply.

Circular challenges

Whether phosphorus re-enters the economy at end-of-life is mostly settled at the design stage. These are the recurring blockers.

• Energy-intensive production

  Elemental phosphorus is made in electric-arc furnaces — only a handful of plants worldwide operate them economically.

• Bound into LFP cathodes

  LFP battery growth is creating a new phosphorus demand stream that competes with food production.

• No closed loop

  Most phosphorus enters food, agriculture, and wastewater — recovery technologies exist but are not yet standard.
