Why One Cracker Closure Can Take Down a Whole Chemical Site

Europe expects a surplus of ethylene, yet one steam cracker closure can still push the plants connected to it toward closure. Cases from Böhlen, Brindisi, Antwerp and Jarrie show how co-product feeds, chlorine chemistry and offtake contracts carry a closure through an integrated site.

A Safety Data Sheet Is Not a Market Passport: What It Can—and Cannot—Establish in Chemical Trade

A safety data sheet is the principal legally prescribed document for passing a chemical's hazards and safe-handling information to the next holder. Under EU and GB REACH, the US Hazard Communication Standard and China's Hazardous Chemicals Safety Law, it carries fields that bear on registration, batch quality, transport and market access, but on its own it settles none of them.

From Polyester Waste to New Products: What Enzymatic PET Recycling Still Needs to Prove

Carbios's recycled-polyester T-shirt validation offers a way to examine what enzymatic PET recycling has demonstrated, why separation and purification matter, and what evidence is still needed for sustained commercial production.

India's Paraquat Decision: The Law, the Chemistry and the Alternatives

India's order of 22 September 2026 prohibits the registration of paraquat dichloride and cancels its certificates from Gazette publication. What the order says compared with the July draft, what paraquat did on Indian farms, the chemistry behind its use and hazards, and the limits of the evidence on alternatives in tea.

PFAS Regulation Enters a New Phase: What 2026 Changes for the Chemical Industry

The 10 October 2026 PFHxA deadline marks a wider shift in EU PFAS regulation, from individual substances toward class-level management. No universal restriction has been adopted yet. For industry, the substitution challenge is reproducing a performance envelope, not finding one replacement molecule.

Why Tirzepatide Is Difficult to Manufacture: Sequence Assembly, Lipidation and Impurity Control

Tirzepatide is a 39-residue peptide carrying a branched C20 lipid side chain on one of its two lysines. No single reaction in its synthesis is unusual — the difficulty is that sequence fidelity, stereochemistry, site-selective lipidation and purification selectivity all have to hold at once. A look at what the published routes and the regulatory record actually say.

Why Phosphoramidite Purity Is Not Enough: Impurity Propagation in Oligonucleotide Manufacturing

A phosphoramidite's headline assay does not describe its manufacturing risk. What matters is whether an impurity can be coupled into a growing chain, at which cycle, what sequence variant it creates, and whether purification and analysis can control the result.

After a Patent Expires, What Actually Stops Anyone From Making the Molecule?

The FDA still keeps a list of drugs that are off patent, off exclusivity, and have no generic at all. Novo Nordisk owns semaglutide outright and still paid $11 billion for filling capacity. Japan restricted three chemicals to Korea in 2019 and only one of them actually bit. This piece gathers the evidence from pharmaceuticals, agrochemicals, and electronic materials into one framework: the Reaction Interface Economy.

Why Do Global Petrochemical Intermediate Prices Always Trace Back to Crude Oil Benchmarks?

Why Do Global Petrochemical Intermediate Prices Always Trace Back to Crude Oil Benchmarks?

Crude oil doesn't set petrochemical prices directly — it anchors a chain that runs through refinery economics, the choice between naphtha, ethane, and coal-based feedstock, cracker margins, and market repricing. This piece traces why ethylene reacts to Brent within days while bisphenol A and epoxy resin lag by weeks, why US shale ethane and Chinese coal-to-olefins routes are decoupling from Brent, and why the deepest competition in petrochemicals runs between carbon resources, not molecules.

Why Do Almost All the World's Laundry Detergents Rely on the Same Chemical Intermediate?

Modern detergents don't compete on cleaning power alone — they compete on what happens after they leave the drain. This piece traces how one carbon chain's shape triggered a global regulatory shift, why LAB plants are secretly refinery chemistry, why a process everyone calls dangerous has run for sixty years, and why only a handful of companies can make it well.

Why Did 20th-Century Oil Mean "Reaching" the Underground, While the 21st Century Means "Controlling" It?

Why Did 20th-Century Oil Mean "Reaching" the Underground, While the 21st Century Means "Controlling" It?

Twenty years ago, "oilfield chemicals" was a sufficient category, because the subsurface served almost one purpose: oil and gas. Today, the same underground space holds CO2, hydrogen, geothermal heat, and lithium from brine — the old label no longer explains reality. This piece names a broader frame: Subsurface Chemical Infrastructure.
