Säker näring i kretslopp

Kursen kombinerar teoretisk inlärning genom föreläsningar med praktiska moment för att nå en ökad förståelse för ämnet. De praktiska momenten är en kompostlaboration, en datorlaboration, ett studiebesök på en avfallsanläggning samt ett projektarbete om riskvärdering.


Kursens tyngdpunkt är biologisk behandling, säker hygienisering, miljövärdering och mikrobiell riskvärdering av kretsloppssystem för biologiskt avfall och decentraliserade avlopp. Detta behandlas i litteratur och på föreläsningar.


I föreläsningar, litteratur, räkneövningar och studiebesök behandlas mängder och sammansättningar på olika fraktioner av biologiskt avfall och avlopp samt hur dessa kan behandlas i olika aeroba och anaeroba processer för avfall och avlopp. Exempel på dessa behandlingstekniker är kompostering, fluglarvskompostering, rötning, infiltration och avloppsdammar. Under kursen fördjupar vi oss i behandlingsprocessers mikrobiologi, termo- och processdynamik, dimensionering, utsläpp, resursanvändning, hygien och praktiska genomförande samt produkternas värde som foder och gödselmedel. Vi går även igenom andra delar av återföringssystemen, t.ex. insamling, distribution och spridning.


Två laboratorieövningar genomförs. I den ena undersöks biologisk behandling i praktiken. Den andra laborationen är en datorlaboration där en miljösystemanalys genomförs. I en fallstudie övas tillämpning av mikrobiell riskvärdering. Ett obligatoriskt studiebesök genomförs vid en avfallsanläggning.

Grading Criteria Safe Nutrient Recycling MX0131

Learning objectives

The course intends to provide an understanding of systems for safe recycling of plant nutrients and organic matter from biological waste and wastewater to cultivation.

After completing the course, the student should be able to:

  1. describe the sources of biological waste and wastewater and explain the characteristics of the different flows,
  2. propose design criteria for safe recycling systems for plant and biological materials from biological waste and wastewater,
  3. describe the difference between microbiological and macrobiological treatment with regard to the biology and processes and the value of the products
  4. describe the difference between aerobic and anaerobic treatment of solid and liquid waste, with respect to both biology and processes,
  5. evaluate treatment systems for composting, anaerobic digestion and small scale wastewater, including source separated sewage systems, with regard to microbial risk and environmental impacts of the systems,
  6. suggest systems and processes that ensure that the recycled nutrients are properly hygienised, as well as describe factors that regulate the inactivation of pathogens,
  7. evaluate results from different environmental systems analyses and microbial risk assessments,
  8. write and orally present proposals for recycling systems for nutrition from biological waste and wastewater and describe the factors that regulate inactivation of pathogens.

These course objectives above are related to three different themes of the course and the grouping of the objectives and what criterias the themes are examined in relation to is shown in the table that follow.
