This thesis examines how nutrients from organic household waste can be recycled in the municipality of Lejre for the benefit of organic agriculture. In the municipality of Lejre, they have started to sort out their food waste this year, and since the municipality has a vision of continuing being the ecological municipality, we found it interesting to investigate how the food waste could be utilized for the benefit of organic farming in the municipality while supporting the ecological profile.In order to respond to the thesis’ problem formulation, we have first examined the field, and this is formulated in a scientific background research, with focus on fx. organic farming, laws and regulations, the importance of nutrients ect. In addition, relevant actors have been interviewed in order to clarify their views and interests, that may affect the recycling of organic household waste. We have used this knowledge in setting up three scenarios, which are evaluated on the basis of five criteria, and we have identified the options and barriers that may exist for different solutions.The thesis concludes that the best scenario to recycle the nutrients from organic household waste, is the one where the municipality of Lejre chooses to construct a composting plant in the municipality. The composting plant can treat the organic household waste without prior treatment. Here, the biodegradable bags from which food waste is collected, can also be degraded in the process, which increases the likelihood that organic farmers will use the composted organic household waste. Because the composting plant is established by the municipality, they may influence the input, ensuring that no biomass is added that is not on the ecological positive list. The location of a plant in the municipality will further make it possible that only just organic farmers from the municipality will make an offer on the fertilizer due to the short transport distance.However, there are several reservations to consider, before this scenario may become a reality, including securing a stable and continuous input, a time perspective and different interests regarding renewable energy vs. nutrition supply. However, the thesis has helped form an assessment basis to work on possible solutions and has also helped in the actualisation of a broader discussion of the importance of recycling of nutrition in a global food system.

Rapporten fremlægger resultaterne fra en sociologisk undersøgelse vedrørende kildesortering af husholdningsaffald i etageejendomme. Undersøgelsen viser, at der findes en udbredt norm om at man bør sortere sit affald. Denne norm bliver også i høj grad omsat i praksis, om end det beror på, at der er velfungerende, let tilgængelige og let forståelige muligheder for at komme af med de genanvendelige affaldsfraktioner. Ejendomsserviceteknikere og ulønnede affaldsansvarlige bidrager til at vedligeholde ejendommenes affaldsinfrastruktur, så kildesortering vedbliver med at være tilgængelig.
