How To Recycle Disposed Fiberglass Fishery Boats

Fiberglass fishing boats, primarily made of Fiberglass Reinforced Plastic (FRP), were once widely used in the fishing industry due to their advantages such as high strength, strong corrosion resistance, and a long service life (typically 20-30 years). However, after being decommissioned, these boats, characterized by high material stability and difficulty in natural degradation, will lead to resource waste and environmental pollution if not properly handled. Their recycling has thus become a key issue in the field of ship environmental protection, yet it is confronted with numerous challenges.

The core difficulties in recycling fiberglass fishing boats first lie in material separation. FRP is formed by the tight chemical bonding of glass fibers (reinforcing material) and resin (matrix material, such as polyester resin). Both physical and chemical separation methods tend to damage the performance of fibers, and currently, there is a lack of low-cost, efficient separation technologies, making the separation work extremely arduous. Secondly, the economic viability of recycling is poor. During their service life, fishing boats accumulate oil stains, seawater salts, and metal components (such as engines and connectors), requiring disassembly and cleaning before recycling, which increases costs. Moreover, recycled materials generally have lower performance (in terms of strength and weather resistance) than virgin materials, resulting in limited application scenarios and low market acceptance.

Mechanical crushing and reuse is a common method: after dismantling decommissioned fishing boats and removing impurities, FRP is crushed into particles or powder using disposed fiberglass fishery boats shredder machine, and then used as fillers in new FRP products or concrete. This method features simple processes and low costs, but the performance of recycled materials degrades significantly, limiting their use to low-strength scenarios. Chemical decomposition for glass fiber recovery can separate glass fibers that retain partial strength, which can be reused in FRP production.

FRP particles crushed by disposed fiberglass fishery boats recycling machine can be used to make low-strength structural parts such as flowerpots and trash cans. As additives in concrete and asphalt, they can improve material wear resistance. Retaining the hull structure and transforming it into sculptures or water landscape facilities also gives old boats new value.
