Evonik Keeps One Chlorosilane Site
Evonik said Friday it will shut Bitterfeld at the end of April 2027 and supply chlorosilane customers from Rheinfelden instead, blaming Asian supply of high-purity silicon tetrachloride. Also on the file this week: the polyvinyl alcohol orders survive a fourth review while three quarters of the tonnes arrive from origins no order touches, Chemours puts a number on North Carolina, and EPA quietly moves ethylene oxide sterilizers into the fumigant paperwork.
Six things moved between Thursday and this morning, and three of them are federal dockets.
That is the shape of the week. The US filings lane stayed shut: two full days of SEC form indexes, 567 8-Ks and 6-Ks between them, and a full-text sweep of the 8-Ks that turns up zero hits on "curtail production", "permanently close" and "idle the plant".
Everything else worth your attention arrived from a German press office or a Federal Register docket.
Here is what is new since Saturday.
Evonik keeps one chlorosilane site, and it isn't Bitterfeld
Evonik said on Friday it will close two German sites.
Hamburg, about 50 people making cosmetics and personal care ingredients, goes by mid-2027, with the work folded into the much larger Essen-Goldschmidtstrasse site. Bitterfeld, about 40 people making chlorosilanes, goes at the end of April 2027, and customers get supplied from Rheinfelden after that.
Read the reason the company gave for Bitterfeld, because it is unusually specific: challenging market conditions for high-purity silicon tetrachloride, increased supply from Asia, competitive pressure, and extended periods of lower plant utilisation.
Then read what they say they tried first. Different operating models. Capacity reductions. Mothballing. A sale of the site. None of it, by Evonik's account, produced a sustainable long-term economic outlook.
That last list is the part worth keeping. A company that has already walked through mothball-versus-sell and come out the other side with a closure date is not going to be talked back across it by one buyer's volume.
The rest of this brief is for subscribers.
The capacity math, the trade-flow read, and what it means for the products you buy.
$50 a month, or $400 a year.
