Abstract [en]

Sales of television sets and computer monitors with flat panel displays have increased dramatically in recent years, and are expected to result in approximately 2.5 billion liquid crystal displays in Europe in the near future. A large investment will be required in Europe as well as globally to handle the large numbers of flat panel displays that are beginning to enter the waste stream today.Given the long-term effects of increased energy and raw material costs, as well as political directives to effect climate change and environmental pollution, it will be a necessity as well as a business opportunity to recycle both the raw materials and components from electronics waste. It is already an accepted truth that “today’s waste is tomorrow’s resources”.The research for this paper aims at exploring what process concepts there are for making an automatic recycling process of flat panel displays. The recycling process shall be both economical and practical to implement in the existing recycling industry.This paper is based on the requirements and needs facing Swedish electronic recycling companies due to the growing amount of electronic waste. This includes the material that will enter an automated flat panel display recycling facility, together with the material and components of interest.The conceptual process has been developed by conducting literature reviews and interviews with recycling companies, as well as by performing practical tests and financial calculations. The result of the evaluation of concepts shows that a circle-saw concept is most suitable, since it has high capacity and provides a good working environment in comparison to the other concepts studied.

Abstract [en]

In a world of growing population and increasing prosperity, the demand for new high-technology products is increasing together with the demand for rawmaterials. To be able to deal with the demand for new raw materials and the increasing amount of waste, the recycling industry needs to prepare itself to cope with these changes. If the waste can become the new raw materials, then the recycling industry has a bright future. The implementation of new ways to recycle products can be the solution to succeeding in this challenge.

The objective of this research is to investigate, from a technical perspective, automation in the recycling industry. More specifically, the objective is to identify problems and solutions in the recycling of plastics and large liquid crystal displays in order to better cope with current recycling requirements.

This research was inspired by the research methodologies of industry-aslaboratory, action research, experimental research and two concept development methods.

The results related to the recycling of plastics come from a theoretical investigation of the possibilities for a plastic sorting facility. The investigation resulted in two concepts for recycling systems, implementable with today’s stateof-the-art technology and a more futuristic concept for sorting and separating the different plastics of interest. The systems are designed with standardised processes and are arranged in a flexible way to be able to manage with current industrial requirements.

The results related to large liquid crystal displays include a clarification of the requirements for an automatic recycling plant, concept generation, and practical testing of different technologies. Two preferred processes for dismantle large liquid crystal displays are the circle saw and band saw. Additional results are the semi-automatic process structure to manage with current industrial requirements for large liquid crystal displays.
