Abandoned Fibre Reinforced Plastic (FRP) fishing boats in the marine environment pose serious environmental challenges. As these boats degrade, they release microplastics, heavy metals, and persistent organic pollutants (POPs), contributing to the pollution of marine ecosystems. Additionally, abandoned boats create navigational hazards, spoil the natural beauty of coastal areas, and occupy valuable fishing spaces. While shredding the debris reduces volume, sustainable repurposing remains a challenge. To tackle this, ICAR-CIFT has developed a new process to convert FRP debris from abandoned fishing boats into an innovative cementitious composite. In the process, FRP debris from abandoned fishing boats were collected and through a series of cleaning, sorting, crushing and pulverizing converts it into powdered FRP (particle size between 300µm- 1mm), which in turn can be used to formulate cementitious composites by mixing with other raw materials.
