Extensive services that protect marine enviroment through a circular model of zero-waste.

Our Group establishes Corporate Environmental Responsibility.

Both at sea and on land, we follow a regenerative approach whereby residue is collected and treated in accordance with the requirements of International Regulations, with the purpose of promoting its reuse through recycling. Adhering to the principles of circular economy, we are committed to creating added value to the resources we manage, while achieving maximum reuse, through the recovery of hydrocarbons, while eliminating waste generation, marine pollution and carbon dioxide emissions.
