- The paper presents details about a doctoral-level EcoDesign course, as an education for sustainable development experience, in relation to pedagogic theory. The aim was to promote transformative learning in order to facilitate more productive use of environmental knowledge in product and business development. The course included interdisciplinary dialogue founded in real world experiences presented by lecturers from business, government and NGOs, as well as study visits and group work on the drafting of journal papers. The key pedagogical objective was to widen the perspective to embrace more humanly engaging concerns and to enhance the student's overall understanding about relations between sustainable development priorities and product design practices. @ 2005 Elsevier Ltd.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- A comparison in total life cycle costs and energy consumption for one high speed ship design with three different structural materials have been performed. The investigation considers a high speed ferry with a steel hull and an aluminium superstructure, an all aluminium concept and a ship built in sandwich material with carbon fibre faces. The different materials will affect several cost elements during the design, the production and the operation of the ship until and including its disposal. Furthermore, the material selection has an impact on the energy consumption within all stages of the ships life cycle. The assessment is made in a comparative manner. Hence, identical out fitting components, e.g. interior, instrumentation, and ventilation are left out. It is shown that the steel version causes the highest costs and energy consumption. The sandwich construction has the lowest life cycle costs while the aluminium version has the lowest energy consumption. The break-even point between the steel and the composite versions appears after 4 years (only 2 years of operation!), the break-even point between the aluminium and the composite ferry is after 12 years (10 years of operation). A sensitivity analysis with different possible scenarios, e.g. change in interest, petrol cost, maintenance cost, has been performed. All of the investigated scenarios identify the composite version to have the lowest life cycle costs. This paper summarises an original work carried out as a master of science work as given in [1-2].

Conditions for recycling and recovery of composite materials
- 2004
-
Konferensbidrag (refereegranskat)abstract
- For composite material as a relative new material group no market for recycled material exists. But with increasing use in structures this will hopefully change. Recycling of composites is also more complicated compared to recycling of traditional structural materials as steel and aluminium since they contain a mixture of fibre and polymeric materials. It is therefore important to identify all conditions that will influence the recycling and recovery of composite materials. These conditions can be divided into internal and external factors. Internal factors are knowledge necessary for implementing the technique and to receive a good result in the end. These factors can be identified through a recently completed project with the aim to form guidelines for material recycling and energy recovery of different composite materials. Here also the economy and the environmental effects for the different recycling alternatives were studied. The results pointed out material recycling as the best alternative for almost all included materials. Examples of internal factors necessary for energy recovery are methods for cutting up the waste, material size before incineration, appropriate incineration temperature and heat value. Before deciding for material recycling or energy recovery there are other types of factors that will influence the choice. These external factors, also known as push and pull factors, are discussed in this paper. Examples are amount of waste, laws and regulations, age of product and type of design.

Environmental friendly recycling of FRP-sandwich ship hulls
- 2005
-
Konferensbidrag (refereegranskat)abstract
- Fibre composite material and sandwich structures are used more extensively especially for transporting structures, vehicles and vessels. This group of materials is young compared to the traditional metallic structural materials. Thus, experience for end of life treatment is missing for these new materials. Increasing environmental demands from customers and authorities forces the manufacturers to act. In this study a model for assessing possible disposal techniques is demonstrated for a sandwich hull from the Visby Class Corvette. The model is based on waste properties and conditions set by the processes involved in the different disposal techniques. Six different disposal techniques are investigated, from reuse to landfill. For the studied structure they are all possible to carry out. When considering external factors as market only two of them are possible today, energy recovery by waste incineration and landfill. According to the waste hierarchy set by the authorities for minimising environmental effects these methods are not on top of the list. Hopefully industrially techniques for material recycling will exists when this sandwich hull is actual for disposal.
