Economic Analysis of Municipal Solid Waste Collection Systems Using Type-2 Fuzzy Net Present Worth Analysis İrem Uçal Sarı and Cengiz Kahraman
Abstract Solid waste management is one of the most important concepts of environmental management due to its direct effect on citizens’ life standards and public health. In this chapter it is aimed to compare underground waste bins and roadside waste bins in a solid waste collection system from economic perspective using type-2 fuzzy net present worth analysis. Results show that underground waste bins should be preferred instead of roadside bins even if they have higher initial investment costs.

Introduction
Solid waste management is one of the most important issues in environmental management, especially for the developing countries. In a developing country, the increase on industrial activities mostly occurs an increase on the volume of the generated solid wastes and it changes their composition. Municipalities of the developing countries should pay more attention on the solid waste management to aware the penalties in the form of resources needlessly lost and a staggering adverse impact on the environment and on public health and safety (UNEP 2005). In developed countries mostly separated collection is preferred for the municipal solid waste collection whereas in the developing countries wastes are mostly collected mixed. For both of the collection types a solid waste collection systems require an effective planning which includes determination of the collection points, the container capacities in that points, the route of the collection process and the transportation of the solid wastes to the disposal areas. To construct an efficient solid waste collection system, there is one more important point which could affect

all of the system requirements, is the determination of the container that which will be used in the system. There are several types of containers which are suitable for different purposes such as separate collection or underground collection of the solid wastes and each of them has different properties such as resistance, capacity, sealing, odor tightness, volume etc. Determination of the waste bins will also determine the trucks used for the collection and the schedule of the transportation. For example, if wastes are collected with roadside bins rather than underground bins, the collection should be scheduled more often to avoid the odor and the visual pollution. The labor requirements, type of the trucks are also affected by this choice. There are several criteria which will lead the determin
