21. Preventative environmental strategies in the service sector
Sammanfattning : Preventative environmental approaches (e.g. Cleaner Production and Pollution Prevention) have been successfully implemented in the manufacturing industry. They are, however, far from being fully adopted by all society actors. LÄS MER
22. Enhanced Biological Phosphorus Removal -Processes, Competing Substances and Tools for Operation of Wastewater Treatment Plants
Sammanfattning : The idea of phosphorus removal at wastewater treatment plants is to transfer dissolved phosphorus into a solid phase. Together with the rest of the produced sludge it is then removed from the water, resulting in a decreased concentration of phosphorus in the effluent and the prevention of the eutrophication in the recipient.

23. 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
24. Green Concurrent Engineering: a model for DFE management programs
Sammanfattning : Environmental considerations in product development are increasingly dealt with in the framework of certified environmental management systems such as ISO 14001. This allows industry to set objectives and assign responsibility for continuous improvement for DFE activities and environmental performance of products in DFE management programs. LÄS MER
25. Sustainable Development: Implementation in Urban Water Systems
Sammanfattning : As Sustainable development, a widely used but poorly understood term, challenges traditional scientific values such as prediction and control, scientists have tried to manipulate the concept to promote their own particular agendas. Thus, it has suffered from misrepresentation which has prevented the concept from being fully implemented at a practical level. LÄS MER
