Failure & root-cause analysis
Field returns, yield excursions, delamination, corrosion, unexplained drift. We find the mechanism, then prove it.

GreenChemX is an independent technical consultancy for manufacturers who have run out of internal answers. We take on the failures, formulations and scale-up problems that stall programmes — and we finish with evidence, not opinion.
What we are called in for
Most of our work arrives the same way: something measurable has gone wrong, the internal team has exhausted the obvious causes, and a customer or a launch date is now at risk.
Field returns, yield excursions, delamination, corrosion, unexplained drift. We find the mechanism, then prove it.
New chemistry, reformulation under regulatory pressure, or a substitution forced on you by a supply chain that moved.
The chemistry worked at 200 mL. It does not work at 2 m³. We close the gap between bench, pilot and plant.
Accelerated life testing that predicts something real, and qualification evidence that survives a customer audit.
Method
Anyone can produce a plausible story about why a material failed. The expensive mistake is acting on the wrong one.
We work the way a good laboratory works: state the candidate mechanisms explicitly, design the smallest set of measurements that can discriminate between them, and let the data eliminate the losers. You see the reasoning, not just the conclusion — which means your team can defend it to a customer, a regulator or a court without us in the room.
Industries
The physics does not change between a wafer and a wind blade. The failure modes, the standards and the commercial pressures very much do.
Thin-film integration, contamination control, packaging stress and the yield excursions that appear three lots after a process change.
Cell and module efficiency loss, encapsulant degradation, PID and the 25-year warranty you signed against a 3-year test.
Electrode formulation, capacity fade, gas evolution, coating defects and the gap between coin-cell data and a shipping pack.
Reaction development, impurity tracking, solvent replacement and the scale-up that behaves nothing like the laboratory promised.
Surface energy and adhesion failure, cure kinetics, bond-line control and durability under humidity, heat and load.
Resin infusion and cure, porosity, interlaminar strength, and joints where a composite has to meet a metal.
Engagement
Four stages, each with a written output you can act on. If stage one shows the problem is not ours to solve, we tell you and stop there.
A 60-minute call with the engineers who will do the work. You bring the symptoms, the history and whatever data exists. We leave with a candidate mechanism list.
A written plan: the hypotheses to be tested, the analytical methods, the laboratories, the timeline and a fixed fee. Nothing starts until you sign it.
Sample preparation, measurement, modelling. Weekly written updates — including the results that do not support the leading hypothesis.
Mechanism, evidence, recommended corrective action and the residual risk we could not close. Raw data included. A debrief with your team, not a slide deck.
“They spent the first week telling us which of our own theories were wrong. That was uncomfortable, and it was the most valuable week of the project.”
Insights
Short technical pieces on the failure modes and methods we keep meeting. Written for engineers, not for search engines.
Lap shear measures the wrong thing for most field failures. A short argument for peel, wedge and humidity-cycled testing instead.
Electrolyte volume, stack pressure and thermal gradients are absent from coin-cell data — and they dominate cycle life.
Most failure investigations collect data that is consistent with every hypothesis. Here is how to design one that discriminates.
Send the symptoms and whatever data you have. A senior engineer reads every enquiry and replies within two working days — with a real technical opinion, or an honest referral elsewhere.
