  2. 11. Phosphorus recovery for fertilisers from dairy wastewater – Sustainability assessment at early stages of technology development

    Author : Marta Behjat; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental impacts; LCA; screening; phosphorus recovery; sustainability; indicator; meta-analysis; wastewater treatment; dairy wastewater;

    Abstract : A reduction in the availability of phosphate rock resources for fertiliser production coincides with an increase in phosphorus-rich dairy wastewater in Europe. This confluence of events has led to the development of technologies for phosphorus recovery from dairy wastewater and the use of the products as fertilisers in agriculture. READ MORE

  4. 12. Coordinated control of Multi-Stage Inventory System

    Author : Johan Marklund; Produktionsekonomi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inventory systems; multi-echelon; stochastic; decentralization; centralized control; distribution system; divergent system; echelon-stock; installation-stock.;

    Abstract : This thesis is based on three scientific papers dealing with different models for coordinated control of multi-stage inventory systems. The ability to control multi-echelon inventory systems, is paramount for reducing tied up capital and inventory costs in large distribution systems. READ MORE

  5. 13. Capacity-constrained production-inventory systems : modelling and analysis in both a traditional and an e-business context

    Author : Zhiping Wang; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Economic Information Systems; Ekonomiska informationssystem;

    Abstract : This thesis addresses issues in production-inventory systems in both a traditional and an e-business context, with an emphasis on capacity considerations. The general aim of the thesis is to model capacity-constrained production-inventory systems and thereby provide theoretical frameworks for control as well as design of these systems. READ MORE

  6. 14. System Expansion and Allocation in Life Cycle Assessment With Implications for Wastepaper Management

    Author : Tomas Ekvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; paper recycling; waste incineration; environmental life cycle assessment; LCI methodology; allocation; waste management; system expansion; system boundaries; life cycle inventory analysis;

    Abstract : The choice of system boundaries and allocation methods can have decisive effects on the results and conclusions of a life cycle assessment (LCA). System expansion makes it possible to model the indirect effects of a decision; however, this modelling is often based on inaccurate assumptions. READ MORE

  7. 15. Flow-oriented studies for environmental management by local authorities : experiences from a regional substance flow analysis

    Author : Annica Lindqvist-Östblom; Linköpings universitet; []
    Keywords : flow-oriented studies; material flow analysis; substance flow analysis; interpretation; local authorities; regional authorities; environmental management; cadmium; sewage;

    Abstract : This thesis focuses on the issue of how to perform flow-oriented studies in order to become more useful for and adapted to local/regional authorities. Compared to traditional environmental monitoring and measurement of the state of the environment, flow-oriented studies are an attempt to broaden the approach to environmental concerns. READ MORE
