01 · Bunker recovery
Make marine fuel work harder.
Daily vessel burn makes every percentage point material. NTROPYX turns fuel loss into a board-level operating figure.
Marine shipping decision page
Marine Shipping
Marine fuel is bought by the tonne and lost by the hour. NTROPYX positions bunker consumption as a recoverable operating cost, not a fixed penalty.

C32 bench evidenceProof context
Marine proof, not generic additive language.
Immediate message: fuel efficiency, cleaner combustion, lower waste and a commercial path sized to the sector.
02 · Marine calibration
Built for real marine fuel families.
Brown and black marine NTROPYX address HSFO, VLSFO, MGO, MDO and IFO380 without hiding the engine context.
03 · Evidence route
Connect proof to vessel decisions.
The Caterpillar C32 ACERT bench context gives technical buyers the right starting point before volume, route and supply discussion.
Why NTROPYX here
- Reference engines include Caterpillar C32 ACERT, report GBT104002132.
- M/V KAYRA remains documented as operational marine evidence.
- NTROPYX is presented as a combustion catalyst, not a conventional bunker additive.
§ 04 · Economic impact
EU27 — 44.4 billion litres of bunker fuel. 14% recoverable.
European international maritime bunkers consumed 1 597 296 TJ of liquid fossil fuel in 2023 (Eurostat) — ~44.4 Bn L diesel-equivalent. Heavy fuel oil dominates ocean-going engines (74%), gas oil powers cleaner SECA-zone operations (23%). At the catalyst dose used in the Caterpillar C32 bench evidence, the recovery scope is unmatched per litre.
