This course explores several aspects of the Enhanced landfill mining concept from landfill characterization to sustainable dynamic landfill management. This course is built on the knowledge and experience acquired during the 4.5 years of the RAWFILL project. This course aims at identifying economically profitable landfill to recover resources (land, energy, materials) and/or implement successful redevelopment project on site. All the tools and methodologies developed within the framework of the RAWFILL project will be presented. To assess the resource available within a landfill, a good landfill content characterization is the key. In this course, participants will learn how to collect data, to do a waste description oriented towards resource recovery and the basis to apply geophysics on site in order to have a more accurate estimation of the volume content and the type of waste. Moreover, the new concept of dynamic landfill management and decision making process to select and launch profitable landfill redevelopment projects will be addressed. Examples of dynamic landfill management and landfill mining project from Wallonia, Flanders, Germany, France and UK will be provided.
The course is divided into four modules:
The participants have the opportunity either to follow all the modules or to select the module(s) that they are interested in. Please note that the Module 1 is mandatory. In the introductory Module (Module 1), the concept of enhanced landfill mining (ELFM) and sustainable dynamic landfill management will be explained in detail in regard with the results of the RAWFILL project, which aims at implementing profitable ELFM project across Europe. Inspiring economically and environmentally profitable landfill mining projects will be presented. The second Module (ELIF) is designed across the data collection required to develop a sustainable landfill management project. For that purpose, the results of a benchmark performed on existing landfill mining initiatives will be presented. In this module, the relevant data to collect prior the launching of an ELFM project would be reviewed. In order to assist the participants, the “Enhanced Landfill Inventory Framework”, a complete landfill database structure developed within the RAWFILL project, will be showed. The participants will have the opportunity to learn how to use it. In the Module 3, the participants will receive an introduction to the HADESS methodology (Acronym for High-performance Acquisition of landfill Data by using a geophysical Exploration and Surveying Strategy) developed within the RAWFILL project. Concretely, they will have the opportunity 1) to learn the basic principles of the main nearsurface geophysical methods used to characterize landfills, 2) to deploy them in real-life conditions, 3) to acquire sufficient knowledge to assess whether the survey is necessary and, if so, to participate in the survey design and interpretation of results. Module 4 focuses on the concept of Dynamic Landfill Management (DLM) and the importance of the decision making process in applying DLM. In this module, the participants will learn how to deal with both the content and context of landfills in order to guarantee a long term and sustainable management. This will be illustrated by real life case studies where driving forces will be identified and evaluated. Furthermore, participants will learn which elements should be taken into account in the decision making process and how the RAWFILL project and tools support this process. This approach will offer the participant a general ranking method for a large number of landfills and more detailed support on individual valorisation options.
Objectives and outcomes
After the introductory Module, the participants will become acquainted with the concept of enhanced landfill mining, sustainable landfill management and landfill revalorization.
After following the Module 2, the participants will be able to identify the relevant data required to develop a sustainable and profitable landfill mining project, and how and where to collect this data. They will have a clear overview of the opportunities and obstacles to launch an ELFM project. Moreover, they will be able to use the ELIF tool and to apply it on real case studies.
At the end of the Module 3, the participants will know the type of information provided by individual geophysical methods, their limitations, key points to be aware of before designing a geophysical study and pitfalls to avoid when interpreting the results. As a result, they will be able to make a critical analysis of either the need or the results brought by geophysics.
After following the Module 4, the participants will be able to (1) apply the concept of dynamic landfill management; (2) deal with the content and context of a landfill; (3) identify important elements of the decision making process within dynamic landfill management; (4) apply decision support tools developed by RAWFILL on a landfill database (Cedalion, Orion).
The target groups are landfill owners, private consultants, companies and NGOs involved in the sustainable waste management, project managers working on recycling facilities, policy-makers, local and regional authorities, academia.

The research focus of his group lies on one hand in solving geophysical inverse problems and associated topics and on another hand in the integration of geophysical data in highly multidisciplinary fields of research.
Eddy Wille joined OVAM in 1991 as project manager soil remediation and was closely involved in the development and organization of the new soil remediation department. Since 1995 he had leading management functions at several services (soil investigation (1995-2000), soil data management (2000-2003); head of department of remedial actions (2003-2012)). In 2012, he became senior advisor and responsible for the OVAM-program on Enhanced Landfill Mining (ELFM). In 2015, his team wrote the memorandum on Sustainable Stock Management of Landfills which was approved by the Flemish government. This concept was discussed with the members of several EU-projects (Cocoon, New-Mine, Minea) and this concept was renamed as Dynamic Landfill Management (DLM), in order to focus on the need to address landfills in a more active way and in view of revitalization in a broader context. In 1999, he wrote the memorandum on brownfield redevelopment which later on became the start of the brownfield program in Flanders (Belgium). From 2001 till 2004, he was chairman of the first steering committee on brownfields which resulted in the Law on brownfield covenants in 2007. In 2009, he was appointed as negotiator and representative of the Flemish government in brownfield covenant projects (linked to the Flanders Innovation & Entrepreneurship Agency). Due to his intervention in 2017, landfill redevelopment is also considered as a specific type of brownfields. Till to date, he was involved in moreover 50 projects and is advisor of the Brownfield board of Flanders.
