Good morning. Today: Goodyear finishes getting out of chemicals, more POE capacity is being built in China than anyone needs, and Daikin plans to destroy PFAS right where it makes them. Hope everyone has a great weekend!

Goodyear is closing its last two chemical plants, in Bayport, Texas and Niagara Falls, New York, cutting about 85 jobs. Niagara Falls reportedly shuts at the end of this month, and Goodyear expects the whole plan to be finished by the end of 2027.
Catching you up:
When we last wrote about Goodyear's chemical business, Goodyear was the last of the old tire makers still making its own synthetic rubber, and it wanted out. Last October it sold that business to Gemspring Capital for $650 million but kept these two plants, which work as a pair: Bayport mainly makes hydroquinone, and Niagara Falls reacts it with a mix of aromatic amines (including ortho-toluidine) to make a mix of diaryl-p-phenylenediamines that keep tires and belts from cracking.
So why the closure?
Goodyear's own numbers tell the story: shutting the plants costs about $30 million in cash and adds $15β20 million a year to operating income, so they're losing money, and the closure pays for itself in under two years. That's likely why Gemspring passed. Niagara Falls also comes with baggage. Ortho-toluidine is a bladder carcinogen, New York cut its air limit for it a thousandfold in 2021, and the state ordered permanent pollution controls by the end of this month, right when the plant reportedly shuts.
Swiss equipment maker Sulzer signed off on the purification unit at Shandong-based BeyondPoly's new 100 KTA polyolefin elastomer (POE) plant. That's BeyondPoly's second plant, more than three times the size of the 30 KTA one it started up in December 2023.
What's going on here?
POE is ethylene copolymerized with an alpha-olefin, usually 1-octene or 1-butene, in a solvent, and Sulzer's DEVO unit boils the leftover solvent and monomer out of the polymer. China is the biggest buyer, and in 2024 it still imported over 90% of what it used, mostly from the US, South Korea, and Japan. More than 40% of those imports were solar grade.
Bigger picture:
A handful of companies, led by Dow, make most of the world's POE, but Chinese producers are catching up fast. Wanhua started a 200 KTA plant in mid-2024, and Lianhong and Sinopec have 100 KTA plants starting up or being built this year. If everything planned gets built, China will have about 2,500 KTA of capacity by 2027 against about 1,800 KTA of demand, so I'd expect prices to fall.
Claros Technologies and Daikin America signed a deal to build a full-scale PFAS destruction unit into Daikin's fluoropolymer plant in Decatur, Alabama.
A little background:
Daikin says its wastewater treatment has cut long-chain PFAS by 99.9% since 2012. Claros breaks the CβF bonds with UV light and proprietary reagents, leaving free fluoride, and in two trials at Decatur, a 50,000-gallon pilot and a 170,000-gallon run, it destroyed over 99.99%, as measured by its own lab. That's another order of magnitude achieved by destroying short- and ultra-short-chains, including TFA.
So, what's next?
The companies were vague: no size, cost or start date, just "over the next few years" and a promise to look at Daikin's other plants. And Daikin is a Claros investor (it joined the $55 million Series B in July), so this reads less like a customer win and more like the next step in Claros's own development.

First produced by Oser in 1861, propylene oxide (PO) was the first chiral molecule detected in space and is occasionally used to pasteurize raw almonds.
Today, China alone can make about 9,300 KTA of PO a year. 60β70% of all PO is used to make polyether polyols (which become polyurethanes), about 20% becomes propylene glycol (to make UPRs and antifreeze), and much of the rest becomes propylene glycol ethers (used as solvents).
Most ways of making PO come with a co-product (here's an introduction to that issue). The old chlorohydrin route leaves salty wastewater. The hydroperoxide routes make styrene (PO/SM) or tert-butanol (PO/TBA) alongside it, except Sumitomo's cumene route, which recycles its cumene. HPPO uses hydrogen peroxide and leaves mostly water. Dow and LyondellBasell have long been the biggest producers, but most new capacity is going up in China.
