A new protected feed hose provides a significant HSE and environmental benefits and a solid green footprint for the aquaculture industry. 85 per cent of the material in the first generation hose is being recycled to manufacture the next two generations. With an annual production and delivery of a million metres of this feed hose, the environment will be spared up to 15 million kg of CO2.
Measurements under practical use shows that the feed hose is significantly more durable than the industry average.
“We worked a long time developing the new antistatic feed hose that meets the requirements of the Labour Inspection Authority and provides a safer work environment on the netpens. The solution was to use a homogeneous plastic material that has a high recyclable factor. Fully 85 per cent of the material in the first generation hose is being recycled to manufacture the next two generations. This is within what we can expect today, but a little bit forward in time maybe we can connect on several generations”, said Innovation Director Jan Dyre-Hansen, who has been integral to the development of the new TESS antistatic feed hose, dubbed the ECOFEEDER.
Greener for the aquaculture industry
A million meters of feed hoses will be manufactured and delivered to Norwegian fish farms this year. “The industry doesn’t have good statistics, but the scope is at this level and is the starting point for our calculation”, said the innovation manager. “It means that the aquaculture industry can help to save at least 6 million kg oil/gas in the manufacturing, which will reduce CO2 emissions by between 12 and 15 million kg. There’s probably even more to gain on the environmental side. Measurements under practical use show that the TESS antistatic feed hose has very good durability, and the expectation is up to 50 percent better than the industry average.”
Promising environmental circle
TESS’s new anti-static, ecofriendly feed hose shows that technology has solved several of the previous challenges in the aquaculture industry. The time with work-related injuries due to electric shock from feed hoses should be over. “The job now is to put in place a good environmental circle where the antistatic feed hoses will have a defined life cycle through three generations. TESS has come quite far in this work, but the logistics between the netpens and manufacturing is a challenge. The distances are large and a hose generation will quickly fill up a couple of semitrailers. Along the way to production the hoses must be cleaned as well. TESS has solutions today, but it remains a little effort to foster the environmental circle into a sustainable concept and put in place several practical solutions”, said Dyre-Hansen.
Keeps its promises
It was a technological breakthrough when TESS developed and put into production a protected feed hose that provides a safer workday at the fish farms.
Its properties have been verified by SINTEF.
The new TESS feed hose is in use by several breeders. “There is only good news from those who have been using the hose for 10 months to transport several hundred tonnes of feed without charging a single volt. That speaks to a proper solution with great durability. The feedback from the users is that the hose keeps our promises”, said Haagensen, “no electrical charge, great durability and UV-resistance.”
ECOFEEDER. New homogeneous protected feed hose for the aquaculture industry. It complies with the Labour Inspection Authority’s requirement for antistatic materials and is tested by SINTEF. Measurements under practical use show that the feed hose is significantly more durable than the industry average. By recycling, 85 per cent of the material in the first generation hose is being used to manufacture the next two generations.
