In the middle of last year (August 2022) we received a prompt request to re-pack 6 containers containing hundreds of plastic bags filled with semi solid sludge.

Repacking this waste in disposable drums took about 4 days by 4 experienced operators at 35°C in the shadow.

A huge and well-meant “thank you” has been received from the shipowner being extremely satisfied with the result.


Ships produce vast amounts of garbage – Marpol V. Under the EU indirect fee system, ships can dispose these in Antwerp without additional charges (*). MAC² is authorized collector in that system and organizes 24/7 collection by barge, by truck, by drop-off container and at our terminal.

Engine sludges, slops, and EGS waste

Collecting and treating liquid maritime waste – Marpol I, II, IV and VI – waste, is at the core of our offering. Our 3 tanker barges operate 24/7, and are supported by truck collection for small quantities. Beneath the traditional sludges and slops, we also handle the more difficult low flash slops, pre-washes and scrubber waste. All waste is treated at our treatment plant in the 4th harbour dock, with maximum recycling of valuable components.
