Utilization of slogans - The situation today

In view of the cost of landfilling fish stocks and changing regulations regarding the disposal of organic waste, companies have focused on the use of slag in valuable products. Processing of slag can be divided into two categories according to the value of the products. On the one hand there is talk of the low-tech industry and on the other hand the high-tech industry. An example of a low-tech industry is the production of digestion concentrate that is used directly for fertilizer use in fields and low-vegetation areas, as well as fertilizer for use in horticulture. Another example is digestion for use in wet animal feed. Processing of enzymes from the stomach and long-tailed cod is an example of a high-tech industry, where a complex processing process is required and products are therefore more expensive. Examples include Pensim, which has been shown to be effective against various skin conditions such as eczema and psoriasis, as well as proteins and peptides that have been used in the food and pharmaceutical industries.

Regarding the costs of disposal of fish viscera and a new regulation concerning the emission of organic waste, the fishindustry have focused on the possible use of viscera into valuable products. Processing of viscera can be divided into two categories based on the value the products. First there is low tech industry and on the other hand high tech industry. Example of low tech industry is the production of silage to be used as a fertilizer to the soil and vegetation compositions area or to horticultural plants. Another example is silage for feed in fur breeding. Processing of enzymes from the intestine of cod are examples of high tech industry, which require complex processing procedure of raw materials to high value products. For example, Pensím which has effective against various skin diseases such as eczema and psoriasis, together with proteins and peptides that have been used in the food industry and the pharmaceutical industry.

Slegist um slógið - Nýtil á slógi frá fiskvinnslum / Utilization of offal from the fish industry

The main goal of the project was to utilize in a profitable way the catch that comes ashore in Þorlákshöfn with catch that is not gutted at sea. The aim was to establish a start-up company, which emphasizes the utilization of the sludge for fertilizer production, along with job creation and foreign exchange savings. The study revealed, among other things, that skyrmysa can be used to acidify the slag in part together with formic acid. Tests on the use of fish manure as fertilizer on vegetated land and cultivated fields showed that the growth of grass and vegetation cover increased considerably.

The aim of this project was to utilize fish viscera from Þorlákshöfn in a profitable way. The aim was the establishment of entrepreneurs, which emphasizes the use of fish viscera to produce fertilizer, along with job creation and saving of foreign exchange. The results included the use of whey along with formic acid for acidification of the viscera. The results of using fish viscera on barren land and agricultural headlands showed that the growth of grass and vegetation cover increased considerably.
