1. Environmental Perspectives on Urban Material Stocks used in Construction : Granular Materials
Sammanfattning : The peoples demand of functions and services in cities is the driver for energy and material flows. Most people in the world are now living in urban areas. In order to achieve a sustainable development of cities, both resource use and environmental impact have to be reduced. LÄS MER
2. Interest in Material Cycle Closure? Exploring Evolution of Industry's Responses to High-grade Recycling from an Industrial Ecology Perspective
Sammanfattning : Many anthropogenically-produced or beneficiated materials contained in “end-of-life” products retain a great proportion of the invested manufacturing work when discarded. Very few such materials are reconstituted and applied in new products at the same material inherent quality level as in their first lifetime – a process known as “closed-loop recycling”. LÄS MER
3. Material Hygiene : An EcoDesign mindset for recycling of products
Sammanfattning : In recent years the end-of-life phase has come into focus. European Union directives have been issued regulating certain product groups and producer responsibility. Vehicles and electronic products are the first to be identified and targeted. EU environmental legislation acts as a driver for increased reuse, recycling and recovery. LÄS MER
4. Designing out waste - Exploring barriers for material recirculation
Sammanfattning : This doctoral thesis has investigated what hinders material recirculation in society, to later suggest possible ways to support material recirculation in the future. Since material recirculation is proposed as a way to use waste materials for new production, it was deemed relevant to investigate two separate case studies that enabled recirculation from production systems and waste management.

5. Innovating Recycling of End-of-Life Cars
Sammanfattning : There are currently a billion cars in use worldwide, and car design trends point at increasing variety in material utilisation. Cars today contain several types of steel and aluminium, an assortment of textiles and padding materials, and an increasing amount of polymers and scarce metals. LÄS MER
