Wednesday 7th - Session G (Pineta Room)

- 9:00 - 10:40
Workshop: Landfill siting
Chair: Giovanni De Feo (IT)

Landfill siting is a complex process, because it needs a multidisciplinary approach that incorporates natural, physical-social sciences, politics, and ethics. The landfill siting process con be conveniently developed combining spatial techniques, such as geographical information systems (GIS) and multi-criteria decision analysis (MCDA). The workshop intends to bring together researchers involved in all these fields with an “open approach” that takes into account the different points of view of all the involved stakeholders. Particular emphasis will be given to social opposition and public opinion involvement.

Introductory lecture:

V. Kumar, A.K. Tangri, P. Kumar (IN)
Landfill site selection for solid waste disposal in part of Lucknow city, India, using remote sensing, GIS and AHP method

10:40 - 11:10 Coffee break

- 11:10 - 12:50
IWWG Workshop: Lessons learned from landfill aeration projects – What are the main criteria for successful approaches?
Chair: Marco Ritzkowski (DE)

Landfill aeration is one of the most important techniques for promoting sustainable bio-stabilisation of MSW landfills. However, results coming from different aeration projects are not always concordant.
 The workshop will consist of some brief presentations, followed by interactive group discussion in order to identify similarities and discrepancies between landfill aeration projects.

Introductory lectures:

M. Rodighiero, P. Pizzardini, R. Raga, R. Cossu (IT)
Low pressure in situ aeration: preliminary tests for real scale implementation
E. M. Bartholameuz, J. P. A. Hettiaratchi, P. A. Jayasinghe (CA)

Selecting aeration configurations to maximize aerobic landfill performance
C. Brandstätter, D. Laner, J. Fellner (AT)
C- and N- balances from a landfill aeration experiment
C. Pacheco, M. Kranert (CO)
Advantages and disadvantages of oxygen supply to old landfills injection of H2o2 in solution

12:50 - 15:30 Lunch break

- 15:30 - 17:10
Workshop: Urban mining and landfill mining I
Chair: Jakob Lederer, Johann Fellner (AT)

The workshop intends to bring together researchers in the fields of so-called urban mining and landfill mining. Selected presentations as well as a group discussion among workshop participants will focus on the definitions and concepts of urban mining and landfill mining, the methods for the exploration and prospection of anthropogenic material flows and stocks for urban mining and landfill mining, the evaluation of anthropogenic material flows and stocks for urban mining and landfill mining. The expected outcome of the workshop is the definition of one (urban and landfill mining) or two (urban mining, landfill mining) task groups potentially to be installed in the International Waste Working Group (IWWG).

Introductory lectures:

V.S. Rotter, S. Downes, J. Huisman, P. Wäger, D. Cassard (DE)
ProSUM - Prospecting secondary raw materials in the urban mine and mining waste – Data sources and data requirements
A. Winterstetter, D. Laner, H. Recheberger, J. Fellner (AT)
Evaluating and classifying landfill mining in analogy to natural deposits
K. Kuchta (DE)
Mining critical metals in e-waste and incineration slags/ashes

17:10 - 17:40 Coffee break
17:40 - 18:00 Poster discussion

- 18:00 - 19:40
Workshop: Urban mining and landfill mining II
Chairs: Jakob Lederer, Johann Fellner (AT)

In Session G10 the discussion started in the previous session G9 will be continued.
