G Perkoulidis, A Malamakis, A Karagiannidis, M Wittmaier, B Bilitewski (2011)  Cogeneration of renewable energy from organic waste in insular settings: a case for the Vietnamese island of Phu Quoc   Journal of Environmental Protection and Ecology  
Abstract: Against the background of global climate change and increasing prices of fossil fuel, the importance of producing sustainable renewable energy increases significantly. CO2-neutral energy generation using biomass or organic waste is an alternative option that deserves attention particularly in developing countries. The aim of this paper is to provide an integrated framework for the preparation of feasibility studies for the renewable energy sector there, considering technical, environmental, economic, socio-cultural, legal and institutional aspects which are particular applicable for developing countries. Such a feasibility framework involves a definition of the scope, which reflects the aims and objectives of the target groups (supplier, operator etc. of renewable energy supply) and the methodologies and tools involved. All relevant aspects are covered: data collection, selection of sites and assessment of options. Furthermore, methods and tools for risk assessment and decision-making are presented and a practical plan of procedures is last provided. The proposed framework is then applied to a selected area in Vietnam and certain results of the study, showing that the implementation of a biogas plant utilizing organic waste would be feasible, are presented in this paper.

Abstract: The development of renewable energy sources has clearly emerged as a promising policy towards enhancing the fragile global energy system with its limited fossil fuel resources, as well as for reducing the related environmental problems. In this context, waste biomass utilization has emerged as a viable alternative for energy production, encompassing a wide range of potential thermochemical, physicochemical and bio-chemical processes. Two significant bottlenecks that hinder the increased biomass utilization for energy production are the cost and complexity of its logistics operations. In this manuscript, we present a critical synthesis of the relative state-of-the-art literature as this applies to all stakeholders involved in the design and management of waste biomass supply chains (WBSCs). We begin by presenting the generic system components and then the unique characteristics of WBSCs that differentiate them from traditional supply chains. We proceed by discussing state-of-the-art energy conversion technologies along with the resulting classification of all relevant literature. We then recognize the natural hierarchy of the decision-making process for the design and planning of WBSCs and provide a taxonomy of all research efforts as these are mapped on the relevant strategic, tactical and operational levels of the hierarchy. Our critical synthesis demonstrates that biomass-to-energy production is a rapidly evolving research field focusing mainly on biomass-to-energy production technologies. However, very few studies address the critical supply chain management issues, and the ones that do that, focus mainly on (i) the assessment of the potential biomass and (ii) the allocation of biomass collection sites and energy production facilities. Our analysis further allows for the identification of gaps and overlaps in the existing literature, as well as of critical future research areas.
M Zygouras, A Karagiannidis, A Malamakis (2009)  Construction and demolition waste processing in Athens, Greece: A pilot demonstration   International Journal of Environment and Waste Management 3: 1-2. 177-192  
Abstract: Construction and Demolition Wastes (CDWs) constitute a waste fraction, which is quantitatively at least as high as municipal solid waste in Greece and other countries. This paper presents the current situation on CDW management in Greece and focuses on the results from the operation of a pilot processing plant. CDW was collected from construction crews at several demolition sites, which included: the demolition of old residential buildings damaged due to an earthquake in September 1999 in Northwest Attica; the construction of 1000 new residential buildings. The operation of the plant is described and an analysis of its operation is provided.

Abstract: The present position paper addresses contemporary waste management options, weaknesses and opportunities faced by Hellenic local authorities. It focuses on state-of-the-art, tested as well as innovative, environmental management tools on a municipal scale and identifies a range of different collaboration schemes between local authorities and related service providers. Currently, a policy implementation gap is still experienced among Hellenic local authorities; it appears that administration at the local level is inadequate to manage and implement many of the general policies proposed; identify, collect, monitor and assess relevant data; and safeguard efficient and effective implementation of MSWM practices in the framework of integrated environmental management as well. This shortfall is partly due to the decentralisation of waste management issues to local authorities without a parallel substantial budgetary and capacity support, thus resulting in local activity remaining often disoriented and isolated from national strategies, therefore yielding significant planning and implementation problems and delays against pressing issues at hand as well as loss or poor use of available funds. This paper develops a systemic approach for MSWM at both the household and the non-household level, summarizes state-of-the-art available tools and compiles a set of guidelines for developing waste management master plans at the municipal level. It aims to provide a framework in the MSWM field for municipalities in Greece as well as other countries facing similar problems under often comparable socioeconomic settings.
