New lead-free line
The Green Heavy Line
Danish producer of fishing equipment, Grønborg Line, has developed a new lead-free line for industrial fishing.
The product, which has been under development for several years, opens up a range of new, environmentally friendly perspectives for the fishing industry.
Among new initiatives in the fishing industry designed to take a more sustainable course, is the ambition to discontinue the use of lead in fishing equipment. Already a legal requirement in Denmark, several other countries may implement similar legislation as well in the foreseeable future.
“There is no doubt that our new heavy line will benefit the fishing industry, especially sea fish farming, which these days accounts for an estimated 55% of our consumer fish”, said Jørgen Grønborg. “Sea fish farming could benefit from Green Heavy Line, primarily due to its environmental friendliness and secondly because it matches the current solutions which uses lead on both the usability and cost.”
The line itself consists of a flexible and very heavy core, which is made of granulate encased by a plastic membrane. The line is produced in one unbroken piece, which can be delivered in exactly the length required.
The weight depends on the diameter of the line. So far it can be delivered in weight units measuring between one and two kilograms per metre. For use in seine fishing, for example, an extra heavy line is available, combining the core material of Green Heavy Line with zinc, making possible a total weight of up to 10kg/m.
Even though the material is heavy, it is as flexible as an ordinary garden hose, and because the main raw material is a recycled bi-product, this new environmentally friendly line is only marginally more expensive than the traditional lines containing lead. Furthermore the relative density of the core is close to that of lead, making the Green Heavy Line only a few millimetres wider than traditional lines and therefore similarly easy to handle.
Grønborg Line says it is ready to enter not only the Danish market, but also the rest of the world's fishing nations. It says that Norway and the rest of Denmark’s neighbouring countries would be important initial markets.
