How to recycle fiberglass reinforced plastic fishing boats?

FRP crusher fiberglass recycling machine

Fiberglass Boats‌: Featuring hulls constructed with fiberglass-reinforced plastic (FRP), these vessels leverage superior corrosion resistance in seawater and lightweight properties to replace traditional metal hulls, significantly reducing energy consumption.Globally, over ‌500,000 active fiberglass fishing vessels‌ remain in service, with an average lifespan of approximately 25 years‌.Annual decommissioned vessels generate ‌2 million tons of FRP waste‌. Fiberglass content in vessel hulls reaches ‌70%‌, with recovery value exceeding ‌$600 per ton.

FRP (Glass Fiber Reinforced Polymer)‌ faces significant recycling challenges due to its complex composition of ‌organic resins‌ and ‌inorganic fibers‌. WANROOE machine presented a recycling plan.

1.Dual-Shaft Shredder‌: Collected FRP products are conveyed via a feeding belt or ‌scraper conveyor‌ into double shaft shredder‌, where they are fragmented into small, recyclable pieces.
2.Hammer Mill‌: Shredded fragments are conveyed via ‌belt conveyor‌ to crusher‌ machine, where they undergo secondary size reduction into ‌fibrous strands‌.
‌3.Impurity Removal‌: Metallic contaminants are extracted using ‌magnetic separation equipment‌.

Fiberglass Waste Transformed‌: Through multi-stage shredding, FRP waste is converted into ‌functional construction fillers‌, delivering "reinforcement through recycling" in brick manufacturing and road engineering, thereby advancing low-carbon infrastructure development.

Brick Manufacturing Application‌: Incorporating ‌5%-15% glass fiber filler‌ into brick raw materials (e.g., cement-aggregate blends) enables uniform fiber dispersion that refines pore structures, enhances inter-particle bonding, and improves ‌compressive strength/crack resistance‌. Concurrently, cement usage decreases by ‌8-12%‌ due to fiber reinforcement, achieving dual objectives of ‌cost reduction and performance optimization‌ for walls and flooring installations.

Road Engineering Application:Incorporating ‌glass fiber‌ into asphalt mixtures (typical dosage: 3%-8%) or concrete (adjustable dosage) fills material gaps, enhancing:
‌Asphalt performance‌: Elevated high-temperature stability and deformation resistance;
‌Concrete properties‌: Improved abrasion resistance and impermeability;
‌Infrastructure longevity‌: Extends service life of roads/bridges while reducing maintenance frequency and costs.
This transforms waste into value-added infrastructure reinforcements, supporting sustainable mega-construction projects
