It started in May 1996 and was supported by the European Commission (DG XII) until December 1997. The established MFA-network will be sustained further. ConAccount provides an international platform for information exchange on Material Flow Accounting (MFA). MFA refers to accounts in physical units (usually in terms of tons) comprising the extraction, production, transformation, consumption, recycling, and disposal of materials (e.g. substances, raw materials, base materials, products, manufactures, wastes, emissions to air or water). According to different subjects and various methods, MFA –and thus ConAccount – covers approaches such as substance flow analysis, product flow accounts, material balancing, and bulk material flow accounts. However ConAccount is generally restricted to studies of (supra)-national and regional scope. MFA projects for products and services (within Life Cycle Assessment (LCA) approaches) are not addressed in particular, although methodological overlaps have been discussed. One of the activities of the Steering Committee of ConAccount is to organise yearly meetings for researchers/policy makers working on/with MFA. This volume documents the presentations of the first ConAccount meeting after the end of the concerted action. This workshop was organised by the Centre of Environmental Science of Leiden University and took place on November 21st at the Vrije Universiteit in Amsterdam. The main topics of the workshop were: 1) dematerialization 2) problemshifting 3) monitoring 4) coupling MFA and societal developments 5) integral policy for materials management 6) combined economic and environmental accounting During the workshop the presentations were organised in nine parallel sessions on the basis of the topics above. In this Volume the papers are organised on the basis of the six topics. We would like to thank all participants of the workshop for their interest and their contributions. The ConAccount Steering Committee: Stefan Bringezu Marina Fischer-Kowalski René Kleijn Viveka Palm 1 Third ConAccount Meeting: Ecologizing Societal Metabolism Amsterdam, November 21st 1998 Plenary Lectures 2 Third ConAccount Meeting: Ecologizing Societal Metabolism Amsterdam, November 21st 1998 Material Flow Analyses Supporting Technological Change and Integrated Resource Management Stefan Bringezu Wuppertal Institute, Wuppertal, Germany Abstract Recent developments are reported on the international consideration of MFA based policy targets. Empirical data on the change of energy carrier productivity in the German Ruhr district indicate that the targets set out in the German Draft Environmental Policy Programme are not unrealistic. Technological change depends on the proper consideration of alternatives. For the example of sewage sludge it is exemplified that the assessment of recycling routes critically depends on the scope of the analysis. Aspects of integrated resource management are discussed considering nitrogen fluxes to German rivers, the cleaning efficiency of municipal sewage treatment plants, the material intensity of waste water treatment and fresh water supply systems. Policy and MFA: Recent Developments As a result of a national debate on sustainability the German environmental ministry has drafted an Environmental Policy Plan which focuses on priority issues, defines a core set of indicators and describes targets and measures to overcome these problems (BMU 1998). The Draft comprises the following targets: · Energy Productivity: increase by a factor 2 (1993 - 2020) · Renewable Energy: increase to 25 % until 2030 · Raw Materials Productivity: increase

  • A Review of Circular Economy Development Models in China, Germany and Japan
    Review A Review of Circular Economy Development Models in China, Germany and Japan Olabode Emmanuel Ogunmakinde School of Architecture and Built Environment, University of Newcastle, Callaghan, New South Wales 2308, Australia; [email protected], Tel: +61415815561 Received: 15 May 2019; Accepted: 2 July 2019; Published: 3 July 2019 Abstract: The circular economy (CE) concept is gaining traction as a sustainable strategy for reducing waste and enhancing resource efficiency. This concept has been adopted in some countries such as Denmark, Netherlands, Scotland, Sweden, Japan, China, and Germany while it is being considered by others including England, Austria, and Finland. The CE has been employed in the manufacturing, agricultural, textile, and steel industries but its implementation varies. It is against this backdrop that this study seeks to identify CE implementation in three pioneering countries (China, Japan, and Germany). A critical review and analysis of the literature was conducted. The results revealed enabling and core policies/laws for the development of the CE concept. It also identified the implementation structure of the CE in China, Germany, and Japan. In conclusion, the findings of this study are expected to serve as a guide for developing and implementing the CE concept in various sectors of the economy. Keywords: China; circular economy; Germany; implementation; Japan; resource efficiency; waste management 1. Background of the Study The linear economy is a waste-generating model. It is a system where resources become waste due to production and consumption processes [1]. The linear economy model is a “take-make-waste” approach [2,3] that extracts raw materials to manufacture products, which are disposed of by consumers after use.

It therefore has a broader scope than a normal licentiate thesis. Here, I would like to share my academic journey in producing the thesis to guide the reader in understanding the content and the background. At high school (standard 9−12), I was most interested in mathematics and physics. This led me to study engineering, and I completed my B.Sc. in Civil Engineering at BUET, Dhaka, Bangladesh. During my undergraduate studies, I developed a great interest in structural engineering. As a result, I chose finite element analysis of shear stress as my Bachelor's degree project. The title of the dissertation was Analysis of Steel-Concrete Composite Bridges with Special Reference to Shear Connectors. All my close classmates at university and I chose an environmental engineering path for further studies. With my interest in environmental engineering, I completed my M.Sc.

  • Future Mayor Tunneling Projects in the Netherlands, 2013-2020
    CONGRESS OF THE ITALIAN TUNNELLING SOCIETY “ TUNNELLING AND UNDERGROUND SPACE IN EUROPE DEVELOPMENT ” Bologna, 17, 18,19 October 2013 Future mayor tunneling projects in the Netherlands, 2013-2020 M. Lipsius, P. Jovanovic Movares Nederland B.V., Utrecht, the Netherlands ABSTRACT: The tunneling industry in the Netherlands has a long history concerning immerse tunnels as well as cut & cover tunnels. In the last 20 years the shield driven tunneling technology (TBM) has been successfully introduced in the Netherlands where the soil condition is very poor. Some of challenging projects ware successfully finished such as: high speed line tunnel Green Heart, till 2006 the biggest in the world, metro Amsterdam, 3 TBM tunnels at Betuweroute, Rotterdam to German border etc. The experience gained with the tunneling projects in the past has created the possibilities for the new projects in the Netherlands. This paper deals with the upcoming mayor tunneling highway projects in the Netherlands in the period 2013-2020 such as: Rotterdamse baan at the Hague, Rijnlandroute at the Voorschoten, Leiden and East-gate tunnel to Brainpark at Laarbeek. All these tunnels have similarities concerning their function , construction method and efficiency to their environment. Engineering company Movares showed that these tunnels are technically and financially feasible. The estimated limited higher cost of the bored tunnels makes them a attractive alternative on regular tunneltypes. 1 Introduction New infrastructure requires appropriate adjustment to its environment. Both in urban and in rural areas is often considerable public resistance present against the new highways. People really do not want to hear, see and smell the traffic which lead to creation of pressure on the planning and processes.

Tel: +4613285625 Email: [email protected] Summary Material flow analysis (MFA) has been an effective tool to identify the scale of physical activity, the allocation of materials across economic sectors for different purposes and to identify inefficiencies in production systems or in urban contexts. However, MFA relies on the invisibilization of the social drivers of those flows to be able to perform its calculations. In many cases therefor, it remains detached from the for example urban processes that underpin them. This becomes a problem when the purpose of research is to design detailed recycling schemes or the like, for which micro-level practice knowledge on how material flows are mediated by human agency is needed.
