The main goal of the project "Microbes for the enrichment of aquaculture sludge" was to develop a method for treating side streams from aquaculture (sludge) with microorganisms so that the sludge can be used as fertilizer for agriculture.  

Considering the rapid growth of aquaculture in Iceland, it is crucial for the sustainability of the industry to find solutions for side currents and thus strengthen the circular economy. The implementation of solutions that promote the use of side streams, and promote circulation, are in line with the United Nations' goals for sustainable development. 

The legal framework for the use of fish farm sludge as fertilizer is both extensive and in parts quite complex, i.e. what is allowed and who grants permission. As an example of the requirements for using sludge as fertilizer, sludge must be applied to the pasture before December 1st if the area is to be used for grazing, animals can then be grazed on the area 5 months later or on April 1st at the earliest.  

In the project, work was done to enrich nitrate in the sludge with microorganisms to increase the possibility of using the sludge as a fertilizer. An enrichment culture was established with the aim of enriching ammonia-oxidizing bacteria in the sludge. A chemical analysis of the sludge was also carried out to assess its nutrient content. The results of chemical measurements indicate that sludge can be ideal as a supplement or additive to, for example, biodegradable livestock manure. It is important to continue with a project that contributes to increasing the value of by-products such as sludge in order to keep nutrients within the circular economy. The use of sludge as fertilizer is beneficial for both aquaculture companies and Icelandic agriculture.

The primary objective of the project "Microorganisms for aquaculture sludge enrichment" was to develop a method for treating side streams from aquaculture (sludge) using microorganisms, thereby rendering the sludge suitable for use as agricultural fertilizer. 

Given the rapid expansion of aquaculture in Iceland, finding solutions for side streams is imperative to sustain the industry and enhance circular economy practices. Implementing solutions that encourage side stream utilization aligns with the United Nations' sustainable development goals. 

The legal landscape for utilizing fish farm sludge as fertilizer is extensive and, in certain aspects, complex, delineating what is permissible and who grants permission. For instance, applying sludge to pasture for grazing requires adherence to specific timelines, such as application before December 1st, with grazing permitted no earlier than 5 months later or on April 1st. 

The project focused on enriching the sludge's nitrogen content with microorganisms. An enrichment culture was established to promote ammonia-oxidizing bacteria in the sludge, increasing its potential as a fertilizer. Chemical analysis of the sludge was conducted to evaluate its nutrient content. The results indicate that the sludge can serve as an ideal supplement or additive, for instance, with biodegradable livestock manure. Continuing projects that enhance the value of like sludge is crucial for maintaining nutrient cycles within the circular economy. The use of sludge as fertilizer is mutually beneficial for both aquaculture companies and Icelandic agriculture.

Fish and other seafood play an important role in ensuring food security, employment and the economy in the world, and especially in the Nordic countries. In addition, seafood of Nordic origin generally comes from sustainably exploited stocks, is particularly healthy for consumption and in most cases has a very limited carbon footprint compared to other protein sources. It can therefore be argued to a certain extent that Nordic seafood is a "sustainable superfood". However, consumers are often not sure if seafood is an environmentally friendly option. The Nordic fishing industry is now faced with the opportunity to take the lead in the energy exchange, and thus be able to boast of offering the best and most environmentally friendly seafood available.

The Working Group on Fisheries and Aquaculture (AG-Fisk) operating within the Nordic Council has identified these opportunities, and as part of Iceland's presidency of the Council in 2023, AG-fisk funded a project designed to promote networking within the Nordic fisheries to increase awareness and share knowledge about past, present and future progress in terms of sustainability and energy transition in the fisheries sector. The highlight of the project was a conference held in Reykjavík on September 13, 2023, but the day before a working meeting was held where opportunities for increased Nordic cooperation were discussed. The conference consisted of 13 talks and about 150 people attended the event, which took place in Harpa. This report contains an overview of the presentations made at the conference. Recordings from the conference are also available at website of the project.

Seafood is generally a climate-efficient and nutritious type of food. Consumers, however, are often confused as to whether seafood is sustainable or not and what seafood to choose. The Nordic seafood sector now has the opportunity to take the lead in transitioning to low greenhouse gas emissions through energy efficiency measures and shifting to alternative fuels.

The Working Group for Fisheries and Aquaculture (AG-Fisk) within the Nordic council has recognized this, and as part of Iceland's presidency of the council in 2023, initiated a networking project to raise awareness and share knowledge on past-, present- and future advances in reduction of environmental impacts in Nordic seafood value chains. The highlight of the project was a conference that was held in Reykjavík on 13 September 2023. The conference consisted of 13 presentations and was attended by close to 150 persons. This report contains the proceedings from the conference, representing an abstract of each presentation and the slides presented. Recordings form the conference are also available on the project's webpage.

Nordic Council of Ministers

Under the Icelandic Presidency of the Nordic Council of Ministers in 2019 the priority was set on youth, sustainable tourism, and the marine environment. This 3-year project is a contribution to sustainable tourism. The project aims to understand the perception of Nordic food, highlight the importance of local food in sustainable tourism, and gain insight into how climate change and trends can shape our future of food in tourism. The objective is to raise awareness of future challenges and opportunities related to food in tourism and provide strategic guidelines that support future actions and policymaking. Our vision is that visiting the Nordics should be about experiencing a place where people and the planet prosper in sustainable harmony and economic growth. Where eating and traveling in harmony with nature and local culture is a desirable lifestyle. Our contribution is not about the competitive advantage but about our drive for a sustainable future.
