A less visible problem than plastic — but just as serious
When we think about marine and river pollution, plastic is usually the first thing that comes to mind. However, there is another silent and equally dangerous threat: oils and hydrocarbons spilled into rivers, lakes, and oceans.
Every year, thousands of tons of oil end up in waterways, coming from:
Uncontrolled industrial discharges
Accidental leaks from facilities, ships, and pipelines
Port activities and maintenance operations
Agricultural and urban runoff
What damage do oil spills cause?
When oil reaches the water, it forms a thin surface film that drastically reduces oxygen exchange with the atmosphere. This phenomenon suffocates aquatic life and severely impacts water quality.
The main consequences include:
Death of fish and aquatic organisms due to oxygen depletion
Harm to aquatic birds, which lose feather waterproofing and the ability to fly
Bioaccumulation of toxic substances in the food chain
Direct damage to local fishing, tourism, and coastal economies
The numbers: global and Italian data
Globally
Around 1.3 million tons of oil are spilled into the oceans every year (source: IMO).
Only about 10% of these spills result from large-scale accidents (such as tanker disasters). The remaining 90% come from routine discharges, minor leaks, and operational activities (source: GESAMP).
In Italy
No fully consolidated national statistics exist, but ISPRA reports highlight that minor, chronic spills happen regularly, especially in port and industrial areas.
Major rivers such as the Po, Tiber, and Arno are among the most exposed due to urban and industrial discharges.
A shocking fact
Just 1 liter of oil can contaminate 1 million liters of water, with catastrophic effects on ecosystems.
Prevention and interception: how to act
Unlike solid waste, oil spills require specialized solutions:
Floating absorbent barriers to capture surface oils
Skimmers and filtering systems to suction and separate hydrocarbons
Monitoring sensors to detect even minimal traces and enable fast responses
Rigorous maintenance and regular checks on infrastructures and facilities
The role of integrated technologies
As with plastics, oil pollution demands an active and integrated approach.
Modular systems like River Cleaning, designed to adapt to various waterways, can be configured to include specific oil containment and collection modules, supporting preventive and immediate intervention against spills.
Protecting rivers and seas: everyone’s responsibility
Fighting oil pollution helps to protect:
Biodiversity and ecosystem health
The quality of freshwater and marine environments
Local economies, especially in fishing and tourism
The health and well-being of coastal and river communities
