As a Port Reception Facility listed on the International Maritime Organization’s (IMO) Global Integrated Shipping Information System (GISIS), we help vessel operators meet their environmental obligations through safe, compliant, and efficient management of regulated marine waste streams.
Operating 24/7, our experienced teams integrate seamlessly with vessel schedules, berth restrictions and port operations, ensuring minimal disruption while maintaining full MARPOL compliance.
Whether your vessel requires a scheduled collection or an urgent response, InterGroup delivers end-to-end marine waste management from collection through to treatment, disposal and resource recovery.
We provide fully managed marine waste services from collection through to transport, treatment and compliant disposal.
