Optimisation of the treatment and disposal of solid wastes in Northern Cyprus

Barışsever, Coşku
Solid waste management has been a key issue of Northern Cyprus for many years as only half of the wastes are properly handled at a sanitary landfill whereas the rest are currently being burned or buried inappropriately at many open dumping areas all over Northern Cyprus which is a serious threat to the public health and the environment. In this study, we propose a mixed integer nonlinear programming model to determine which treatment facilities to build and their sizes, whether the current landfill should be extended or not, and when to extend the current landfill if it is to be extended so that all solid wastes generated in Northern Cyprus are properly handled and the total cost of the proposed system is minimised. Among several treatment facilities, anaerobic digestion, composting, waste-toenergy facilities, landfill, and clean and dirty material recovery facilities are considered in the model besides recycling of solid wastes through source-separation by households. The proposed optimisation model has been applied to the case of Northern Cyprus and solved by an open source optimisation solver. The results revealed that if sufficient landfill capacity is available and a good participation to recycling can be achieved, recovery of recyclable materials, landfilling the remaining wastes and sometimes building a composting facility is the least cost solution of the solid waste management problem. On the other hand, building a waste-to-energy facility becomes inevitable if the landfill capacity is insufficient. However, the total cost of a system with a waste-to-energy facility is very high compared to the case without such a facility.


Modeling of settlement in saturated and unsaturated municipal landfills
Durmusoglu, Ertan; Corapcioglu, M.Yavuz; Tuncay, Kağan (American Society of Civil Engineers (ASCE), 2006-07-01)
Municipal solid waste (MSW) landfills are not only used to dispose the refuse in most economical way but also utilized as a viable land in today’s waste management strategy. Settlement prediction is an important issue in order to guarantee the integrity of any postclosure structure on landfills. In this study, landfill settlement in saturated and unsaturated landfills is investigated by developing a one-dimensional mathematical model and performing numerical experiments. Under the saturated conditions, the ...
Evaluation of the hazardous waste landfill cap system design and clay layer thickness criteria of the Turkish Regulation on the Control of Hazardous Waste (RCHW) using the Hydrological Evaluation of Landfill Performance (HELP) model
Piskin, F. Yalcin; Demirer, Göksel Niyazi (Inderscience Publishers, 2007-01-01)
The hazardous waste landfill design criteria of the Turkish Regulation on the Control of Hazardous Waste (RCHW) was evaluated in this study. In the first part of the study, Hydrologic Evaluation of Landfill Performance (HELP) model was used to determine the significance of different components of the hazardous waste landfill cap system as required by the Turkish RCHW. In the second part of the study, the top and bottom clay layer thickness requirement of the Turkish RCHW was evaluated by running the HELP mo...
Performance evaluation of landfills with the HELP (hydrologic evaluation of landfill performance) model: Izmit case study
Yalcin, F; Demirer, Göksel Niyazi (2002-10-01)
Landfilling is the most economical and commonly used final disposal method of municipal solid and hazardous wastes. Leachate, which is the inevitable output of the landfills, may cause serious pollution problems if not properly handled. In this study, the hydrologic evaluation of landfill performance (HELP) model was used to examine the performance of the hazardous waste lot (HWL) of Izmit Industrial and Domestic Solid Waste Sanitary Landfill for three different cases. These cases were the (1) existing desi...
Municipal solid waste management with cost minimization and emission control objectives
Mohsenızadeh, Melıka; Kentel Erdoğan, Elçin; Tural, Mustafa Kemal (null; 2017-10-14)
Proper management of municipal solid waste (MSW) has been a crucial aspect of every society due to its social, environmental, and economic impacts. Operations research techniques have frequently focused on cost minimization objectives in locational planning of municipal solid waste management (MSWM) systems. However, transportation constitutes an integral part of this system producing a considerable amount of greenhouse gas (GHG) emissions. Therefore, sustainable management of this system with GHG emissions...
Use of rubber and bentonite added fly ash as a liner material
Çokça, Erdal (Elsevier BV, 2004-01-01)
In many countries regulations require all hazardous waste disposal facilities to be lined with suitable impermeable barriers to protect against contamination. In this study, a series of laboratory tests on rubber and bentonite added fly ash were conducted. The aim of the tests was to evaluate the feasibility of utilizing fly ash, rubber and bentonite as a low hydraulic conductivity liner material. Type C fly ash was obtained from Soma thermal power plant in Turkey; rubber in pulverized form was waste from t...
