2. Entry requirements:
Completed university or 2nd level Bologna studies from the wider field of natural
history, mathematics and computer studies or the narrower field of life sciences
3. Objectives of the course and intended learning outcomes:
Educational aims: The subject is intended to provide in-depth knowledge on types,
properties and energy potential of waste biomass in agriculture. Students are
acquainted in depth with biotechnological procedures that are suitable for obtaining
renewable energy from waste biomass and, at the same time, are directed (in
themselves or in groups) to protection and remediation of the environment.
Intended learning outcomes: The obtained knowledge, in combination with other
knowledge of the doctoral program, enables a relevant judgement of behaviour with
waste from the agro-food field, planning suitable strategies and operative guidance of
biotechnological procedures for renewal and stabilisation of waste organic biomass.
4. Syllabus outline:
Side products of animal and plant production are considerable quantities of
organically heavily burdened sewage and solid (mainly plant) waste. Above all waste
and sewage from the production of domestic animals greatly burden the environment
and it is necessary to suitably remove or reprocess such waste. Anaerobic biogas
technologies offer good possibilities of microbial reprocessing of organic compounds
in animal sewage and the production of renewable energy sources (reprocessing of
biogas into heat or electrical energy). Because animal sewage exceeds optimal
concentrations of nitrogen, in biogas technologies it is ideal in combination with waste
plant biomass, which is rich in carbon. The stress in biogas technologies will be on
exploitation of waste sources of biomass and avoiding the use of planned production
of biomass, such as wheat and silage. Additional removal of nitrogen takes place with
nitrification-denitrification biotechnological solutions and plant purifying equipment.
The subject will stress the mentioned biotechnological solutions and their
applications, and various possibilities of combined technological and biotechnological
solutions will also be reviewed.
