The
formal host for the project was Sauer-Danfoss A/S, Nordborg. The
project has been carried out with the help of Michael
Hauschild (project supervisor) Department of Industrial Production and
Management, Tom Tychsen (supervisor in the company) and other staff
members in the company and Department of Industrial Production and management. The
aim of this project is to perform a Life Cycle Assessment
(LCA) on the Hydraulic motor type OMV/W-800. The goal of this study is to
clarify the impact potentials, including environmental impact potentials and
resource consumption throughout the entire lifespan of the hydraulic product
system. The work began by gathering company specific and subcontractors’ data
on different parts of the hydraulic product system, and LCA methodology provided
by the EDIP book is utilized as a tool. Many
of Sauer Danfoss A/S suppliers did not want to disclose data on their production
due to fear of competition and confidential agreements with third party
suppliers. Even with the knowledge of my confidentiality agreement with
Sauer-Danfoss A/S, many of the suppliers and company employees were unwilling to
cooperate with me. Thus the data collection proved to be very time consuming.
Especially data on ancillary substances, proved to be hard to acquire. Therefore
the main conclusions are drawn on incomplete data with regard to toxicity
impacts. The
appendix part of the report presents detailed data and descriptions on different
stages e.g. appendix A presents data on processes, transport and environmental
impact assessments on the raw material + semi-products. It is recommended to
read chapter 1 and chapter 5 of appendix A, which contains important
information. Appendix AA contains detailed data, and can be read by choice.
Appendix B provides detailed data on ancillary substances used in different
processes inside Sauer-Danfoss, and environmental impact assessments on the
manufacturing stage. It is recommended that all chapters be read in order to
understand the basic data. Sub appendix BB is a part of appendix B,
which contains detailed calculation data information
and can be read by choice. (Please note that Appendix B and BB contain
confidential data, and will therefore not be available for public use). Appendix
C presents detailed descriptions on the use of the hydraulic motor, motor age
estimation, energy consumption estimation and environmental impact assessment in
the use stage. It is recommended that Chapter 2, chapter 3 and chapter 7 be read
in order to understand the basic data in Appendix C. Appendix D presents data on
the disposal of the hydraulic motor and materials in the product system and
environmental impact assessments in the disposal stage. The
last part of chapter 1 contains confidential data, and will therefore not
be available for public use in Appendix D. The
appendixes contain information, which are considered confidential by the
manufacturers and Sauer-Danfoss. Consequently, the appendix reports should be
treated confidentially. Important information reported in the appendixes
concerning significant parts of the main report is listed below:
Appendix
E contains information about the EDIP-tool’s weak points, further
recommendations, and “processes-tree” data. Appendix F and
Appendix G contain project related information; therefore it is up to the reader
to read them if there is any doubt about the data.
Acknowledgement:
My supervisor, the Project Leader, Michael Hauschild, Department of Industrial Production and Management, was most helpful. I thank him for the supervision and support during my work with this report. For technical support, I would like to thank Morten Als Pedersen IPL, and the department staff members. I would also like to specially thank Finn Boje Johannessen for the technical support (computer technical problems) he provided me with throughout the execution of this project. I
would like to thank everyone who has helped me to achieve the results I have
gotten.
