Formål

The aim of the course is to provide knowledge on basic processes leading to gaseous emissions from livestock production units. In the course, chemical, biological and physical processes that affect or lead to gaseous emissions, will be treated. Focus will be on properties of selected gases, manure processes, slurry-air exchange, direct emissions from animals and atmospheric fate. Gases to be discussed include ammonia, greenhouse gases and odorous compounds.

Indhold

The course will provide the students with fundamental knowledge of the gaseous emissions such as ammonia, greenhouse gases, odour, odorants, and dust, which are produced and emitted from livestock facilities.

Læringsmål

Pass of this course will make the student able to:

• Identify environmentally harmful gases from animal production units
• Describe physical and chemical properties of ammonia, greenhouse gases and odorous compounds
• Describe the concept of odour (concentration, intensity, hedonic tone and threshold values)
• Describe methods to estimate odour (dynamic olfactometry)
• Describe the processes (biology, chemistry, physics) which lead to the production and volatilization of environmentally harmful gases.
• Describe characteristics of dust emissions from livestock production
• Apply the concepts of solubility, phase partitioning and diffusion to evaluate slurry-air exchange for individual compounds
• Apply mathematical expressions used in emission calculations
• Discuss methods for estimating emission rates of environmentally harmful gases and odour from animal production units

Discuss the influence of important emission processes under different conditions

Studieordning og bedømmelse

Kandidatuddannelsen i biosystemteknologi

• Hj.opg. + Mdt., bedømt efter 7-skala med intern censur

Approval is a combination of 2 written reports 8-10 pages and oral examination. One report is worked out in groups of 3-5 students, and one is done individually. Each student specifies the contribution to the reports. Oral examination for 20 min without means of aid. The reports and the oral exam counts equal.

Internal examiner, the Danish 7-point grade scale
