Adisseo Commentry Plant (France) →
FRCommentry, Allier, Auvergne-Rhône-Alpes · chemical_plant
Adisseo's legacy European methionine and feed additive plant; formerly Rhône-Poulenc Animal Nutrition production site. Produces liquid methionine analog (Rhodimet NP99 / Rhodimet AT88) and specialty additives including vitamins. Chinese-owned (ChemChina via Bluestar) since the 2006 acquisition. Commentry is a secondary facility to the Nanjing China flagship but remains critical for European supply continuity.
Adisseo Nanjing Methionine Plant (China) →
CNNanjing, Jiangsu · chemical_plant
Adisseo's flagship China production facility; DL-methionine and liquid methionine (Rhodimet). Primary supply hub for Asian poultry and pet food markets. In 2024 Adisseo announced a 100,000 MT/year additional capacity expansion at Nanjing. Chinese state ownership (ChemChina/Bluestar via CNBG) means this facility's output is politically controllable by Beijing. The Nanjing plant's capacity expansion drives China's growing share of global methionine supply.

Did you know2023
Adisseo, the world's second-largest methionine producer, has been fully owned by the Chinese state since 2006 — via China National Chemical Corporation (ChemChina) subsidiary China National Bluestar Group (CNBG). This means Beijing controls approximately 25% of global DL-methionine supply through a French-branded company with European production facilities. Every commercial poultry operation globally using Adisseo Rhodimet is technically dependent on a Chinese state enterprise as a critical feed input supplier. ChemChina's 2006 acquisition of Adisseo preceded its 2017 acquisition of Syngenta ($43B) — together ChemChina now controls a significant share of both crop protection chemicals and the amino acids added to livestock feed, two inputs that are non-substitutable in modern industrial agriculture.
