The purpose will be to analyze and develop environmental friendly technological and whole system solutions for organic biowaste utilization and recycling in agriculture, with a main focus on animal manures.
Participation in the course will give students a fundamental understanding of technologies for treatment of bio-waste that can reduce the emissions to environment (water courses, greenhouse gases, ammonia and other odours etc.) and other threats (e.g. soil compaction, hygienic questions) due to the animal production. The student will achieve an ability to analyse and a capacity in presenting data and processes. The course will give insight and hands on experience in the functionality of environmental technologies for the treatment of bio-waste, in particular animal manures.
Specific themes to be covered in the course will be:
- Separation of bio-waste slurries into a liquid fraction and a phosphorous and dry matter rich solid fraction through application of mechanical separation with or without additions of flocculants.
- Reactor technologies for biogas production from bio-waste materials.
- Composting of organic bio-waste materials for stabilisation and quality improvement.
- Technologies for the reduction of the emission of odour, ammonia and greenhouse gases from stored bio-waste.
- Bio-waste land application techniques to reduce ammonia emissions.
- Biomass application to land for crop production, the mineral fertiliser value of the biomass.
- Nutrient- and energy-system analysis of biowaste management options with the use of mathematical models
Before the course commences, each student must write and submit a short report (5-10 pages) on home country manure management, i.e. animal manure production statistics, management technologies and regulation of animal waste use.
The on-campus part of the course (40 hours) will consist primarily of lectures, case-based exercises and hands-on laboratory work in teams. The course includes excursions to industries or waste water treatment plants using biomass for energy production and environmentally friendly technologies. Through these activities the participants will be introduced to the available environmental technologies for treating bio-waste, to systems analyses and mass balance modelling.
Subsequent the on-campus part of the course, the students must write individual report. This project must be inspired by their PhD project, and it must include a system analysis (initiated on-campus) of an identified problem and suggested solutions.
Course termination will be an (on-line) oral presentation of the report, and an active participation in discussion of the topics.
At the end of the course, the student should be able to:
- Apply mathematical models for systems analysis on biowaste flows
- Analyse the design of energy conversion technologies
- Discuss the whole system of bio waste management and cycling at the scale of the livestock farm
- Assess the biowaste management regulations effect on environmental impact.
The course gives important competences for jobs in private or public advisory service, environmental technology industry R&D, public administration and international organisations, as well as teaching and research at college and university level.
