Sardinia Symposium News and New Courses This Year


11 th AUGUST 2009

The Twelfth edition of the Sardinia Symposium, SARDINIA 2009 will include two general sessions and six specialized and workshop sessions for a total of eight parallel tracks.

Papers were selected according to quality by a group of International Referees from nearly 800 abstracts from 62 countries.

In the current edition the main topics include: waste policy and legislation, waste management strategies, waste characterisation and waste management in developing countries.

This year a number of innovative topics such as waste electric and electronic equipment (WEEE) and bioenergy production will be introduced.

During the meeting several interesting case studies and major controversial subjects will be discussed, representing an excellent opportunity for exchange of knowledge and experiences.

The 26 scheduled workshops will focus on numerous hot topics such as Waste minimization, Heath issues in waste management, Long term emissions, Sustainable landfilling, Waste management and Global Climate Change, and Biological production of Hydrogen.

The workshops will be preceded by a short introductory presentation followed by discussion between leading experts in the field. Discussions of this nature form the core of the symposia, in which the actual transfer of ideas, experiences and technology takes place.

The final programme is available in the web site


Training courses dealing with the topics listed below will be organized by the IWWG ( and held on October 4th 2009 immediately prior to the start of SARDINIA 2009. Delegates who wish to register for the training courses are invited to contact the IWWG Secretariat (e-mail:
The course will focus on simple rotting techniques and particularly on the aerobic degradation process and enhancing of the latter; on the delivery and storage of different biogenic wastes, pretreatment of feedstock, how to control the composting process and compost finishing. Delegates will discuss the advantages and disadvantages of open windrow composting systems compared to enclosed reactor systems. Moreover, different aspects of process forcing, possible emissions (e.g. odor, leachate) during composting and influences on compost quality will be dealt with. The course will be chaired by the chairman of the IWWG Task Group on “Compost quality” Erwin Binner, from the BOKU University of Vienna, Austria<
Landfill design and waste pretreatment play a central role in the development of potential environmental impacts from landfill sites. The training course will focus on: waste pretreatment methods aimed at improving waste quality; types of landfills, e.g. reactor landfill, “dry tomb”, inorganic landfill, sustainable landfill ; technical barrier systems, leachate collection; top cover systems, including methane oxidation. The course will be chaired by IWWG Managing Board member Peter Lechner, from the Institute of Waste Management of BOKU University, Vienna, Austria.
The course will provide a comprehensive overview on biogas production, extraction, transportation and utilization. Basics on LFG production modelling will be presented, including the latest approaches used by the Intergovernmental Panel on Climate Change (IPCC) for the calculation of Greenhouse gas emissions. Problems and risks associated with LFG, such as explosion protection and measures for LFG cleaning, will be highlighted. A central aspect of the course will deal with the exemplarily design and dimensioning of a LFG extraction system for a virtual landfill. The course will conclude with the demonstration of different possibilities for energy recovery from LFG. The course will be co-chaired by the chairman of the IWWG Task Group on Landfill Aeration Marco Ritzkowski and the IWWG chairman Rainer Stegmann, from the Hamburg University of Technology, Germany.

The course will begin with a basic introduction to the processes of leachate generation and leachate composition and will follow on the treatment of landfill leachates at a wide range of landfills, in a wide range of climatic conditions, using a variety of treatment processes. Case studies will cover leachate treatment systems installed in temperate and tropical climates, in developed and developing countries and will include some of the largest leachate treatment systems in the world. Discussion will be encouraged at the end of the course, and throughout a practical and case-study based approach will be adopted. The course will be chaired by IWWG Managing Board member Howard Robinson, Technical Director of Enviros Consulting, UK.

LeachXS-Orchestra is a database/decision support tool for characterisation and environmental impact assessment of (contaminated) soil, sludge, compost, sediments, various types of municipal, industrial and hazardous wastes, mining wastes, preserved wood, treated wastes, stabilised waste and construction materials based on contaminant release as derived from leaching tests. The training course will focus on the following aspects: comparison of different leaching tests; statistical data evaluation and quality control options; comparison of lab, lysimeter and field data; geochemical speciation modelling of leaching test data; predictive modelling of release in different exposure scenarios; data input tool; LeachXS Lite; reporting functions. Interactive sessions about example cases, with contribution from all the participants, will be organised during the course. The course will be chaired by the chairman of the IWWG Task Group on Leaching Assessment Methodology and Tools, Hans Van der Sloot, from the Energy Research Centre of the Netherlands (ECN).
The IWWG Training Course on Sustainable Landfill Concepts will focus on advances in landfill technology and on the current options available for the sustainable management of landfill sites. An overview of processes in the traditional landfill will be given, followed by the description of innovative landfill concepts with examples of full-scale implementation worldwide. The main issues that will be addressed are: processes and emissions in the traditional landfill; landfilling of pretreated waste; semiaerobic and aerated landfills; remediation of landfill sites by means of in situ aeration and landfill mining. The course will be chaired by Roberto Raga, doctor in Geoengineering and Assistant Professor at the Department of Hydraulic, Maritime, Environmental and Geotechnical Engineering (IMAGE) of the University of Padova, Italy
The course will provide knowledge of principals and issues concerning solid waste management in low-income and developing countries. It will present an overview on the planning and operation of waste management systems regarding the challenges of developing world and discusses appropriate solutions, emphasizing the correlation with environmental health, water management, sustainable development, and Climate Change.
The time has come to think about organising the Social Events for the Symposium and, particularly considering that for most of us garbage is not the only exclusive source of fun, we would like to arrange a sort of "Do-it-Yourself" evening during which Delegates attending the Symposium will perform on stage.

Therefore, the Organizers would be most grateful if those of you (including your companion) who can sing, play a musical instrument (and can bring the instrument with them to the Symposium: drums and piano will be available on site) or dance, and who would like to take part in a "Sardinia Symposium Show" could kindly send a mail to the Organising Secretariat

( ) stating their availability to contribute to what should prove to be a fun evening! Hurry to put your name down for one of the most entertaining evenings you have had in years……..

Coming soon: Info on the Opening Session and the final Round Table. During the Opening Session on Monday 5th Oct., papers focusing on the association between the worldwide economic crisis and waste management will be presented. The final Round Table, on Friday 9th, will deal with the hot topics of food waste, the next big challenge in the waste management world.

The Waster recommends the Sardinia Symposium as the top global waste management event. Sadly, the Waster himself, who did have the abstract of his paper this year approved for presentation, will not be able to attend this time, due to lack of funds due to recessionary belt tightening measures, otherwise he would be there like a shot! (by the way! – If anyone has a spare ticket, I can use, because they are unable to attend at the last minute for any reason please do email me!)
