The day biogas said enough: arc flash collapse

Published on 2026-07-02 | Translated from Spanish

The biogas processing plant suffered a total collapse following a fire caused by an arc flash in the methane enrichment area. The incident, which mobilized emergency teams, exposed flaws in the safety protocols of a facility that promised energy efficiency. Investigators are now analyzing the causes as the smoldering wreckage serves as a reminder of what could have been prevented.

Pipeline 3D: from point cloud to simulated disaster 🔥

The 3D modeling of the incident was carried out with Pix4D, which generated a precise point cloud of the collapsed area. The data was imported into PyroSim to recreate the fire progression and the behavior of the arc flash. This combination allowed engineers to identify critical ignition points and flame propagation in the enrichment area. Preliminary results suggest that a failure in the insulation of an electrical conduit was the trigger, aggravated by the accumulation of methane in non-ventilated areas.

Methane took the day off and left the bill 💸

The most ironic part of the case is that the plant, designed to convert waste into clean energy, ended up generating a light and sound show that not even the best rock festival could match. Technicians are now debating whether the arc flash was a technical failure or a protest from methane for feeling exploited. Meanwhile, neighbors are asking if next time they will give advance notice so they can make popcorn.
