BioSok™ – Natural, Nontoxic and Biodegradable Bilge Sock


BioSok™ is a nontoxic, biodegradable, and easy-to-use bilge sock for pleasure craft. Placed in the boat bilge, the BioSok™ will absorb and biodegrade the motor and fuel oil that leaks under normal boating conditions – preventing oils from escaping into marina waters. When you need to protect marine waters from boat bilge oil and other fuel contaminants, trust BioSok™.

How it Works

Placed inside a boat bilge, the BioSok™ floats on top of the water in the boat bilge and beings to absorb the oil, reducing odors while simultaneously biodegrading the leaking motor oil and fuel. PRP Powder, the active ingredient in the BioSok™, consists of tiny microspheres of treated wax, which contain nutrients. When the PRP Powder in the BioSok™ encounter the fuel oil or other hydrocarbons, the spheres “bind” with the oil, absorbing it. Nutrients within the sphere attract naturally occurring microorganisms from the immediate environment, creating an ideal ecosystem for them to flourish and begin to biodegrade the fuel and motor oil.
BioSok™ typical lasts a full boating season (4-6 months)
When BioSok™ is depleted, simply throw away the fabric sleeve – no special disposal required
For a pleasure craft 40′ or smaller, one BioSok™ is recommended per season
