LNAF10044U Life Cycle Assessment within Biological Production Systems
Bacheloruddannelsen i naturressourcer
The course covers general LCA theory:
1. Goal and scope definition
2. Inventory analysis
3. Life impact assessment
4. Interpretation of results
This include important subjects like definition of functional unit, system boundary delimitation, allocation, system expansion, change-oriented versus accounting LCA, consequential versus attributional modeling. Impact assessment methodology and sensitivity analysis.
Special emphasis will be given to various environmental and resource conservation problems that arise in conjunction with products of biological production systems (e.g. horticultural crops, field crops, production animals, aquaculture, food industry, pharmaceutics). The students are also introduced to the concept of cost benefit analysis (CBA) and illustrative examples of CBA based on value transfer will be given.
Upon completion of the course the students should be able to:
- Identify major environmental impacts of biological production systems - Show overview of the theory of life cycle assessment (LCA)
- outline the definition of scope, goal, inventory analysis and impact assessment - Describe how LCA can be used for improving production systems
- Reflect about pros and cons of LCA software.
- Summarize the transfer of LCA results to economic cost-benefit analysis (CBA)
- Describe alternative environmental assessment tools and their applicability
- Use LCA software and apply it to practical cases
- Apply LCA on different kinds of products of biological production systems - Analyse factors that influence the environmental impact of biological systems directly or indirectly
- Assess the conclusions in LCA-reports
- Discuss environmental problems associated with biological production systems
- Present an understanding of potential consequences of the results of an LCA
- Suggest improvements to biological production systems in terms of environmental impact with the aid of LCA
- Link LCA-outcomes with the CBA of economists and discuss the implications of this.
1. Introduction to the theory, principles and application of LCA;
2. Use of the acquired LCA competences on a self-chosen case-study of a product or process of a biological production system.
In the first part, the general theory of life cycle assessment will be presented the form of lectures and exercises and the students will be acquainted with life cycle thinking. In addition, the students will get hand-on experience with LCA software and acquainted with the possibilities of its use through exercises. A case study and several small exercises will illustrate the principles relevant to biological production systems such as land use, eutrophication, global warming etc.
In the second part the students will choose a case among a limited number of possibilities from a biological production system according to their interests. An expert in the area will act as a client requesting a LCA, while the student will act as LCA experts carrying out the assessment. This will be done in study groups, but the students will each write an individual discussion of the results. This case will serve to illustrate some of the practical problems with LCA in more detail and train the use of LCA software. In addition, lectures given by specialists of relevant fields, real life LCA application will be illustrated.
