Mar Egeo, 1992: 87% of the crude degraded in 12 days

It is the most solid figure that exists for this bioremediator, and it was not published by the company that makes it: a public body measured it.

CSIC measurement on the Mar Egeo spill (1992). Trial carried out by BioPulcher.

What happened

In December 1992 the tanker Mar Egeo ran aground and caught fire off the coast of A Coruña. It was one of the major hydrocarbon pollution episodes in Spain's recent history, and the starting point for applied bioremediation in the country.

The trial

The first Spanish trial of the bioremediator now supplied by BioPulcher was carried out on that spill. The Marine Research Institute of Vigo, part of the CSIC, monitored it and recorded 87% degradation of the crude in 12 days.

Why that figure matters so much

Because it meets the three conditions that make a number credible: an independent third party measured it, that party is a public research body, and it was done on a real spill rather than in a laboratory. In a sector full of percentages with no origin, a figure with that provenance is worth more than any promise.

Attribution: this trial was carried out by BioPulcher, the company that supplies the bioremediator PortCleaner uses. PortCleaner took no part in it: in 1992 it did not exist. What this case proves is the effectiveness of the product, not our track record.

What you can and cannot conclude

You can conclude that the product degrades hydrocarbons measurably and within short timeframes. You cannot conclude it will deliver exactly 87% in any port: temperature, oxygenation, type of hydrocarbon and surface all change the outcome. That is why our site talks about a 1:1 reference ratio and one to two days, and does not repeat the 87% as if it were a guarantee.
