DL-Methionine (Essential Amino Acid Supplement)

Evonik Industries AG (XETRA: EVK; Essen Germany; MDAX listed); world's largest DL-methionine producer under the MetAMINO brand. Total DL-methionine capacity exceeds 700,000 MT/year across three continental hubs: Jurong Island Singapore (~340,000 MT/year — world's largest single methionine complex, expanded +40k MT August 2024), Theodore Mobile County Alabama USA (~245,000 MT/year), and Antwerp Belgium (~120,000 MT/year). The Wesseling Germany DL-Met line closed Q1 2021 as Evonik consolidated production to the three-hub network. Evonik first commercialized DL-methionine synthesis in the 1950s under predecessor Degussa. MetAMINO is Evonik's largest single product. ~30-32% global market share. In February 2022 Evonik announced a $176.5M investment in a new methyl mercaptan (MMP intermediate feedstock) plant at the Alabama site.

Adisseo; owned by China National Bluestar (CNBG, a subsidiary of ChemChina/Sinochem Group — Chinese state); French-heritage feed additive company; world's largest producer of liquid methionine (Rhodimet/Rhodimet AT88); ~25% global methionine market; plants in Commentry France, Nanjing China, and Guangan Sichuan China; 2024 announced 100k MT expansion in Nanjing; Chinese state ownership means ~25% of global methionine is controlled by Beijing; Bluestar acquisition completed 2006 for ~€400M

Novus International (Chesterfield / St. Charles MO USA; owned 80% Mitsui & Co. Japan + 20% Nippon Soda Japan); global animal nutrition company producing ALIMET (HMTBa — 2-hydroxy-4-(methylthio)butanoic acid), a liquid methionine hydroxy analog that is approved as bioequivalent to DL-methionine in poultry and swine diets. ALIMET plant at Chocolate Bayou TX near Alvin Brazoria County (~284,000 MT/year nameplate capacity; first shipment 1984). Also produces MFP (Methionine Feed Grade Powder) and gut health products. ~10-15% global methionine market share. Note: ALIMET is an analog (not identical to dry DL-methionine) — approved by FDA and EU for equivalent nutritional use in poultry. US-based production is Japanese-owned, not American-owned. Revenue ~$650M/year.

CJ CheilJedang Corporation (Seoul South Korea; KRX: 097950; subsidiary of CJ Group); South Korean food and bio conglomerate; world's largest L-lysine producer (~25% global share) via fermentation biotechnology. Operates the world's first and only commercial-scale bio-based L-methionine facility at Kertih Biopolymer Park Terengganu Malaysia (80,000 MT/year; opened 2015 using genetically engineered E. coli K-12 fermenting plant sugars — producing L-methionine rather than racemic DL-methionine). CJ's fermentation-route L-methionine is chemically distinct from synthetic DL-methionine but is approved as nutritionally equivalent in poultry diets. Also produces tryptophan, threonine, and other feed amino acids globally. Pet food market interest in fermentation-derived (non-petrochemical) amino acids is growing.

Chinese domestic DL-methionine producer (Sichuan province); completed a new 70,000 tonnes/year production line in 2025, raising domestic market share ~9% and representing the fastest-growing challenger to the ABCD Western players; part of China's strategic push to reduce amino acid import dependency; listed on Shenzhen Stock Exchange
