Landfillworkshop 2011

Specialist workshop on LANDFILLS OF HAZARDOUS WASTE AND ITS IMPLICATIONS ON HEALTH AND ENVIRONMENT

Second Announcement

Workshop to be held at Luleå University of Technology, Sweden, November  15-17, 2011 and hosted by Profs. Sven Knutsson, Roland Pusch and Nadhir Al-Ansari at the Dept. of Civil, Mining and Environmental Engineering in close cooperation with its associate Prof. Raymond Yong, Canada and Prof. Kadhim Al-Muqdadi, Sweden

Background and purpose of the workshop

The workshop offers possibilities for specialists interested in the design and performance of landfills for hazardous material to discuss the nature of the processes in engineered barriers, particularly clay-based liners, and ways of modelling them. The workshop will focus on practical matters and be based on geological, geotechnical and soil physical issues, and also on construction methods. The importance of long time behaviour in different climatic regions will give focus on degradation of liner material in long time perspectives, 103 years and more. The need to discuss and form a common basis for the performance of liners and cover layers is of utmost importance for proper design of these types of landfills.

A second purpose is to consider the disposal and isolation of depleted uranium emanating from weapons and ammunition used in the Iraqi war. The problems with pollution and effective isolation of such slightly radioactive waste are very similar to those of safe disposal of hazardous chemical waste. Both can be located under quite different climatic conditions, which put significant demands on the isolation of the waste and require detailed consideration of how clay-based barriers operate.

The first part of the workshop will be of interest to hydrogeologists, geotechnical, environmental and geological engineers.  Physicians, pharmacologists, biologists, limnologists and agricultural scientists will find Part 2 of the workshop to be of particular interest.

PART 1. LANDFILLS OF HAZARDOUS CHEMICAL AND MINERAL WASTE PRODUCTS

Session 1: Construction in different geological and climatic environments.
Some of the major themes will be GWL issues, drainage; desert condition; arctic conditions; high precipitation; impact of earthquakes (liquefaction)

Session 2: Design and function of landfills and different barriers
Major issues are: compressible/incompressible underground, drainage, internal and surface erosion, percolation/collection, exogenic impact, longevity, instrumentation, legislation and including EU laws and regulations.

Session 3: Experience, case histories, follow up.
Important topics: practical cases, successful and unsuccessful, ways of improving and repairing, cost.

Session 4: Conclusions and suggestions
Panel consisting of all sub-session chairmen giving their respective opinions and conclusions aspects.

PART 2. LANDFILLS OF DEPLETED URANIUM IN IRAQ

Figure 1. Example of possible technique for disposal of DU implying placement and compaction of sandwiched clay/waste covered by suitable top liner and resting of a corresponding bottom liner.

The basis is known effects of DU on human health and environment, the objectives are to elaborate ways and means to save the environment from DU pollution, and to assess the role of the society and professionals to minimize the effect of DU. This part of the workshop has two sessions, each of them ending with summing-ups and conclusions as well as recommendations for future work:

Session 1: Disposal and monitoring of radioactive pollution of DU (cf. Figure 1)

Major issues are: principles for disposal of DU, use of engineered barriers, diffusion through barriers, long time performance in different climatic conditions

Session 2: Effect of radioactive waste of DU on the environment and health.

Session 2 of the workshop is expected to be of particular interest to physicians, pharmacologists, biologists, limnologists and agricultural scientists.

Practicalities

Time and location

The workshop will be held at Luleå University of Technology, Luleå, Sweden, November 15-17, 2011. Workshop-registered attendees are encouraged to prepare papers to be presented at the workshop. The papers will be reviewed by the organizing committee for being accepted for presentation on the Workshop homepage and they will be submitted for publication in a special volume of Engineering Geology (Elsevier Publ. Co), requiring examination by reviewers appointed by the journal.  

Individual oral presentation of accepted papers and prepared statements from the session chairs, will provide the basis for the panel discussions. The time for oral presentation of individual papers will be 15-20 minutes per paper. The workshop language is English. 

Abstracts and papers

Abstracts with a length of 400 words in maximum should be sent to the organizers no later than May 31, 2011. Full papers based upon accepted abstracts should be prepared according to the Elsevier Publ. Co. Full papers are due on September 30.

Registration and fees

The fee including participation and meals is given on homepage and is approx. 4500 SEK.
