  1. Lessons learned • Valentin Feodorov prof. • National Conference “Management of permanent development of municipal waste. Concepts and strategies” • Bucharest - 2013 during the execution of 28 municipal landfills

  2. Current framework in Romania • 50 landfills must be operational in the year 2017: • 45 regional municipal landfills • 5 ecological landfills for isolatedareas • 28 landfills were in operation in January 2013 : • 16 ecological landfills – private investments • 12 ecological landfills financed by ISPA and POS Environment programs • 17 landfills have the documents prepared in various stages of execution / designing / financing proposals

  3. Waste landfills performed in Romania until 2012 Functional ecological landfill financed by ISPA and POS Environment Programs Functional ecological landfill executed by private funds Landfills financed by ISPA and POS Environment programs at which has not been designated yet the operator by tender

  4. Legal frame in Romania Waste Framework Directive no. 2006/12/EEC Directive 1999/31/CE– regarding the waste storage Law 211/2011 on waste regime GD 349/2005 – regarding the waste storage (transcription of Directive 31/1999) OM 757/2004 Technical Normative regarding the waste storage (according to ED 31/1999 si GD 349/2005)

  5. 7 basic rules for landfills designing and execution • Maximum sealing; • Proper sized drainage; • Waterproofing and drainage intended forever; • Landfill covering is compulsory after filling ; • The chosen location must provide natural sealing guarantees; • Leachate must be collected and treated in a Treatment Plant; • Landfills must be permanently monitored !

  6. Other criteria taken into account to landfills designing • Site selection; • Execution; • Emplacement; • Hydrostatic level of the groundwater.

  7. Choosing the locations depending on land topography 16 projects financed by private funds, to which can be added the Țuţora sitefor Iaşi regional landfill, have had flat lands as emplacement. The election of some sites located on slopes was the most often met option for the other applications financed from European funds:

  8. Complying the geological/ geotechnical criteria in electing the location Geotechnical criterion has been analyzed at the stage of choosing theoretically the site and in the phase named “Feasibility Study”, the geotechnical studies did not meet the elaborating requirements, most of times not even being checked in accordance with Law no.10/1995 regarding the quality in constructions by MLPTL authorized auditors. Were chosen landslide emplacements in areas with structured clays type PUCM and active underground headsprings, etc.

  9. Lining systems • Behaviour areas for HDPE geomembrane: • elastic area between 0 and 35 kN/m • relaxation area between35 and 25 kN/m • creep area at25 kN/m • cold-hardening area between25 and70 kN/m. Curbele caracteristice ale geomembranei HDPE 2 mm la încercarea la tracțiune.

  31. Economic aspects The contracts concluded with various Contractors for the execution of new landfills and closure of nonconforming landfills were based on FIDIC norms (RED and YELLOW). Between FIDIC norms and the Romanian legislation for public acquisitions (Ordinance no. 34) exist important differences that have left their mark on the works’ execution. There are now litigations in courts between the Beneficiaries (County Councils and various Contractors to solve disputes arised from the different way of understanding the FIDIC norms and the Romanian legislation for public acquisitions, especially the Ordinance no. 34 .

  32. Conclusions For Romania, the waste management program that it has to fulfill by 2017 is extremely important. From the 28 ecological landfills opened and 139 landfills closed until 2013 resultsed that the knowledge level in this field dramatically needs to be heightened. Because of the traditionally conservative outlook in academic circles, Universities have not included yet in their curricula themes connected to the computation and technologies of soil structures built with geosynthetic materials. Therefore, one propose that starting with the fall of 2013 short-term post-graduate courses are organized, granting the graduates a professional degree, for all categories of personnel engaged in survey, design, execution, follow-up and supervision of these works. To begin with, three themes seem to be of an immediate interest: Selection of sites for the opening of new deposits and the forensic implications; Safety and durability of lining systems; Closure of the existing landfills and surveillance systems. The continuous cooperation with the worldwide scientific community in the field of geosynthetics, which we treasure greatly, remains a priority for Romania.
