Proposals for thesis
Sustainable landfill management:
- evaluation of long term emissions from landfills;
- optimization of degradation processes in hybrid landfills.

Landfill remediation by means of in situ aeration:
- carbon and nitrogen balance during landfill aeration;
- characterization of leachate and biogas in aerated landfills;
- influence of process parameters (temperature, aeration rate, leachate recirculation) on the efficiency of in situ aeration.

Landfill remediation by means of Landfill Mining:
- characterization of waste fractions after Landfill Mining in view of re-use.

Curriculum Vitae
Roberto Raga is Doctor in GeoEngineering (Cagliari, Italy, 2000) and since February 2006 he is Assistant Professor at the University of Padua, Italy.
At the same University, since 2008, he teaches the course of “Remediation of contaminated sites” for international students of the Second Cycle Degree Programme (MSc Level) in Environmental Engineering.
His teaching and research activities are focused on municipal solid waste treatment and disposal in landfill, management of leachate and biogas emissions, old landfill remediation.
His main area of expertise is in situ aeration as a tool for reducing current and long term emissions from landfills. To this regard, he has carried out the scientific management of three full scale landfill aeration projects in northern Italy in recent years.

Dr. Raga was involved in the following international projects funded by the European Union (EU) and the Italian Ministry of Foreign Affairs:
- PSDWSEP - Pre-treatment and safe disposal of municipal solid waste and waste water sludge for environmental protection (EU, FP5, 2000 – 2002);
- EVAPASSOLD - EVAluation and Preliminary ASSessment of OLd waste Deposits (EU, FP5, 2000 – 2004)
- TETRAWAMA - Development of Teaching and Training Modules for Higher Education in the Waste Management Sector (EU, Asialink project, 2003 – 2006)
- Cooperation project Italy – China: ROLES –Remediation of Old Landfills for Environmental sustainability and final sink (Italian Ministry of Foreign Affairs, 2016 – 2018)

He is member of the IWWG (www.iwwg.eu) and of IWWG task groups on:
- Landfill aeration;
- Sustainable landfill management.

He is member of the Executive Programme Committee of Sardinia Symposia, acting as Scientific Secretary.

He is author of more than 60 scientific publications in Proceedings of International Conferences, national and international Books and Journals
