Waste management is an integral part of sustainable urban development. In the modern world, when attitude to waste is being shifted towards “waste as resource” and “waste as income generator”, ensuring separation of hazardous waste from the general waste stream becomes increasingly important. Sorting hazardous waste is critical in light of the whole recycling idea. Hazardous elements, while bearing a certain value if properly handled, can negate the costs of the recyclable materials if found in their stream. They present enormous long-term losses, if introduced into the environment, and can negatively influence our ability to benefit from recycling. Convenience is one of the most effective tools in increasing recycling rates (Carlson 2001, p.1275). It is a personally defined concept, and often depends on the users’ lifestyle-related factors. This thesis explores users’ understanding and habits of handling hazardous waste, as well as the challenges they encounter and their views and suggestions on convenience of hazardous waste recycling systems. The main method used in this comparative case study research is qualitative interviews conducted with a variety of people with different lifestyles living in Malmo. First, the thesis develops a list of lifestyle-related factors which lower the perceived convenience of recycling. People consider recycling to be effort demanding or easy not just because they are women or men, young or old, live in a dense area or not. But this perception is influenced by having or not having access to a transporting vehicle and time available, their household’s waste producing rates, time spent living in a certain place, available space for storing waste; physical constraints or difficulties with self-organization at home; established or not recycling habits or level of environmental concern. People’s recycling behavior is determined by these personal lifestyle-related factors. Second, aspects of convenience are being presented as the focus areas which planners should consider in increasing recycling rates. The convenience aspects are developed with regards to the challenges people with different lifestyles experience in recycling. While lifestyle-related factors cannot be influenced directly, aspects of convenience can be employed in ensuring efficiency of hazardous waste collection system. It is important that the hazardous waste collection system design takes them into the full account. Detailed descriptions of the aspects of perceived convenience are presented. They are grouped into convenience of access to information and convenience through facilities and services. The final conclusion of the thesis is that involving users would assist in addressing key aspects of recycling systems’ perceived convenience and increase their efficiency. It is hoped that the information can be helpful in designing successful hazardous waste collection systems with increased capability to reach national goals in recycling and reduce the amounts of hazardous substances in general waste.
