The Hidden Crisis Underwater
Beneath the surface of UK rivers and coastlines, thousands of abandoned GRP vessels are slowly degrading. These ghost boats release toxic chemicals and microfibres that contaminate the food chain, creating an invisible ecological catastrophe that demands an urgent, circular solution.
THE GRP BREAKDOWN
From Hull to Hazard
Glass Reinforced Plastic (GRP) does not biodegrade. Instead, it undergoes a slow, destructive fragmentation process. When boats are left abandoned in riverways, the structural integrity of the hull is compromised by UV exposure and mechanical weathering, leading to the systemic release of hazardous materials into the environment.
- Physical fragmentation into microscopic shard-like particles.
- Persistent shedding of synthetic resins and chemical surface binders into the water column.
- Leaching of legacy anti-fouling toxins and heavy metal concentrations.
- Migration of harmful microfibres into riverbed sediments and local estuaries.
Infiltrating the Food Chain
The degradation of GRP vessels releases persistent microfibres into aquatic environments, triggering a dangerous process of bioaccumulation. These microscopic pollutants are first ingested by primary consumers—planckton and small invertebrates—which are unable to expel the synthetic material. As these organisms are consumed by larger marine life, the concentration of microfibres increases, moving up the trophic levels.
Ultimately, these synthetic particles reach top-tier predators and eventually enter the human food supply. This hidden crisis not only threatens marine biodiversity but poses long-term risks to human health as chemical additives within the fibres leach into organic tissues. Marine Loop addressing this at the source by ensuring end-of-life boats are effectively recycled before they can begin this toxic cycle of decay.

Composite Regeneration
Using advanced mechanical recycling, we break down end-of-life hulls into raw composite materials, redirecting waste from landfill back into industry.
