Polyglycolic acid (PGA) and polyester polymer for absorbable sutures

Medical-device giant; absorbed Covidien — maker of Polysorb braided absorbable sutures and surgical products.

Dutch biobased ingredient company (Euronext Amsterdam: CRBN, HQ Amsterdam; formerly CSM N.V. sugar/food division); world's largest producer of lactic acid and pharmaceutical-grade lactates via bacterial fermentation of corn starch and sugar. Corbion's Purac® pharmaceutical sodium lactate (formerly Purac Biochem, now Corbion Pharmaceutical Ingredients) meets USP/EP requirements for injectable sodium lactate used in Lactated Ringer's solution. Corbion is simultaneously the leading pharma sodium lactate supplier, the leading polylactic acid (PLA) bioplastic monomer supplier (LUMINY® PLA for packaging, 3D printing, medical devices), and a major food ingredient company (lactic acid as preservative E270, emulsifiers for baked goods). One Dutch company is the foundational supplier for: hospital Ringer's IV bags, compostable coffee cups, biodegradable 3D printing filament, and artisan bread shelf life extension — all from the same bacterial fermentation process using corn starch as feedstock. Corbion operates fermentation plants in the Netherlands (Gorinchem), Thailand (lactic acid capacity), and USA (Blair NE).

J&J's surgical products subsidiary; world's largest manufacturer of sutures, wound closure, and surgical stapling devices; Vicryl® absorbable suture controls the largest share of the global suture market; also makes electrosurgical devices and surgical mesh.

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.

Japanese specialty chemicals; produces bead-shaped activated carbon (BAC) for high-performance water treatment; Iwaki Japan facility

Japanese chemical conglomerate (TYO: 4183, HQ Tokyo); recognized as the quality leader for ultra-high-purity electronic grade IPA for semiconductor applications, achieving parts-per-billion impurity levels. In Q2 2024, Mitsui Chemicals introduced a bio-based IPA derived from renewable acetone with 25,000 MT/year initial capacity — part of Japan's push toward bio-based chemicals. Mitsui is one of the world's leading specialty chemical companies with deep ties to the Mitsui Group keiretsu (same group as Mitsui & Co. trading, Mitsui Fudosan real estate, etc.). Mitsui Chemicals' IPA is particularly important for Japanese and Taiwanese semiconductor fabs. The company that dominates bio-based IPA is also part of the same industrial group that owns one of Japan's largest steel mills (Nippon Steel was historically Mitsui-linked).
