| Technical purpose of product or process | Sinker tube for 157m pens (Pipe ø400mm) As one of few suppliers of equipment to the fish farming industry, ScaleAQ is an approved supplier of pens, nets and mooring equipment. Both at home as well as abroad, we exclusively employ certified plastic welders with considerable experience of cage assembly. Our certificates are approved in accordance with the requirements of NS 9415. The sinker tube is optional in accordance with the floating collar. Scale AQs floating collars and sinker tubes combines the flexibility and durability of high density polyethylene plastic pipes with strong steel brackets. A sinker tube helps prevent the shape and thus the net volume from changing in locations subject to storms. The sinker tube is designed to make the handling of the net easier. All ScaleAQ pens are certified for use with a sinker tube. Benefits using sinker tube: Safety: - Reduces point load on nets. - Gives you full control during lining up. - Minimal risk of propeller damage to nets. - Stable net volume, even under extreme conditions. Environmental benefits: - Open mesh ensures good through-flow and less marine growth. - “Constant” cylindrical net volume means fewer injuries and stress for the fish. - A sinker tube makes delousing using sealed tarpaulins easier in large net pens. Easier cleaning: - Easy washing using brushes/high-pressure washes or divers. - Net drying without significant changes to net shape. |

| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Allocation: The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |
