This report is part of the project "Improved quality, shelf life and reduced waste in the value chain of Icelandic vegetables." roughly estimate the amount of by-products that occur on an annual basis. In addition, chemical measurements were performed on selected by-products.

The report contains a summary of conclusions and proposals. It is believed that there is great potential for value creation from the by-products that occur during vegetable production in Iceland. One way of value creation is the isolation of bioactive substances for use in food, dietary supplements and cosmetics. Possibilities also include fermentation and acidification of by-products and their processing for incorporation into food. Horticultural waste must also have waterways that lead to utilization. Food safety should always be the first issue when developing products from by-products. It is therefore necessary to make measurements of undesirable substances in by-products before new products are developed.

This report is a part of the project „Improved quality, shelf-life and reduced waste in the vegetable value chain.“ The main tasks were studies of (a) current utilization of by-products from the vegetable production, (b) possible product development, (c) information on toxins in the by-products, (d) amount of available by-products. Additionally, nutrient analyzes were carried out on selected by-products.

The report includes conclusions and proposals. It is concluded that there are considerable possibilities for value creation from vegetable by-products. One of the possibilities is the use of bioactive compounds from by-products for food, supplements and cosmetic products. Other possibilities are fermentation and addition of homogenized by-products to foods. Wastes from horticulture should also have routes for utilization. Food safety should always be considered when food uses of by-products are considered. Therefore, by-products should be analyzed for contaminants and toxicants.

By-products from whitefish processing / By-products from catfish processing

This report summarizes information on the utilization of important catfish species in Iceland, explains which products are processed from the resulting raw material and examines the possibilities for increased utilization of by-product raw materials. The report is prepared in connection with the Nordic research project "Alt i land" led by the Faroese company Syntesa. "Alt i land" is part of the Faroese Presidency's program of the Nordic Council of Ministers, which examines the current utilization and possibilities for improving utilization in catfish processing in the Faroe Islands, Greenland, Norway and Iceland. The main results from this project show that utilization in catfish processing in Iceland is significantly higher than in the other countries. In addition to publishing this report, Matís has held two workshops in connection with the project, where stakeholders came together to discuss possible opportunities to increase utilization and value creation in catfish processing.

The objective of this report is to analyze the current utilization of the most important Icelandic whitefish species and identify possibilities for improving utilization of by-raw materials even further. The report is a part of a larger international project, called “Alt i land”, which is led by the Faroese company Syntesa. Alt i land is a part of the Faroese chairmanship program at the Nordic Ministers of council. The objective of Alt i land is to study and compare utilization in whitefish processing in Faroe Islands, Greenland, Norway and Iceland, and to suggest how utilization can be improved in these countries. The main results from that project show that utilization is much higher in Iceland than in the other countries. In addition to publishing this report, Matís has facilitated a series of workshops with selected stakeholders where potentials in increasing utilization have been discussed.
