Investigation of waste stabilization potential of a medium aged solid waste in a bioreactor landfill

Hot, Elif. (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2012., 2012.)

The production of solid waste is an inevitable consequence of human life. The tremendous increase in the solid waste generation makes the use of landfills, especially bioreactor landfills imminent. Research has shown that ...
Evaluation of biogas production as a source of renewable energy though co-digestion of agricultural residues and poultry manure

Göl, Nefise Pınar. (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2012., 2012.)

The need for alternative energy sources for Turkey is obvious. Biogas production via agricultural residues and manure seems to be an advantageous option for Turkey, since the main income is generally provided from the agro ...
Determination of biogas production potential from various supermarket wastes

Alkanok, Gizem. (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2013., 2013.)

Up to date, alternative methods have been investigated to both decrease the environmental effects of wastes and also meet the growing energy demand considering the new technological developments. Then, biogas production ...
Production of biogas through anaerobic co-digestion of ice cream plant wastewater and ice cream production residue

Örok, Murat. (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2012., 2012.)

The primary objective of this study is to determine whether it is possible to dispose of ice-cream production residue (off-spec) and ice-cream wastewater together and to recover energy by anaerobic co-digestion process. ...
Evaluation of in situ leachate management alternatives on municipal solid waste stabilization in sanitary landfills

San, İrem. (Thesis (M.S.) - Bogazici University. Institute of Environmental Sciences, 1999., 1999.)

An alternative approach for treating municipal solid waste involves the treatment of the waste after landfilling by addition of moisture to the waste. Increasing attention is being given to municipal solid waste landfill ...
Analysis of surface ozone in Istanbul by using cluster analysis and HYSPLIT model

Güler, Meltem. (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2011., 2011.)

Istanbul is the largest and most populated city of Turkey and one of the biggest megacities in the world. In the framework of the TUBITAK-COST project 105Y005 and TUJJB-TUMEHAP project number 03-06, one urban (Göztepe which ...
An integrated approch to water management in Kayseri : rain water collection and storage design for Kayseri Harıkalar Dıyarı water-ski park

Karakoçak, B. Begüm. (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2011., 2011.)
