Abstract

This study examines the optimization of the waste collection system to ensure the efficient management of recyclable wastes generated within a university campus. Within the scope of the study, the positioning of collection points and the planning of collection routes for recyclable wastes such as plastic, paper, and glass are addressed from a cost minimization perspective. Within the framework of the management system, data on area-based user numbers and recyclable waste production amounts obtained from different usage areas within the campus (faculties, cafeteria, library, cafes, dormitories, restaurants, and social areas) were utilized. Accordingly, using GAMS (General Algebraic Modeling System) software, a mathematical model was developed and solved, taking into account the distances between collection points and waste processing facilities, vehicle capacity constraints, and transportation costs. The applicability of the model was examined; the effects of collection routes on occupancy rates, transportation distances, and total costs depending on the intensity of use throughout the campus were evaluated within the framework of different scenario analyses. The results obtained show that the proposed optimization approach reduces total transportation costs and contributes to more effective and efficient execution of campus waste collection activities. In this context, it has been demonstrated that the developed and proposed model can be used as an effective decision support tool for planning and managing sustainable recycling systems in university campuses.

Özet

Bu çalışma, üniversite kampüsü içerisinde oluşan geri dönüştürülebilir atıkların etkin yönetimini sağlamak amacıyla atık toplama sisteminin optimizasyonunu incelemektedir. Çalışma kapsamında, plastik, kâğıt ve cam gibi geri dönüştürülebilir atıklar için toplama noktalarının konumlandırılması ve toplama rotalarının planlanması, maliyet minimizasyonu perspektifinden ele alınmıştır. Yönetim sistemi çerçevesinde, kampüs içindeki farklı kullanım alanlarından (fakülteler, yemekhane, kütüphane, kafeteryalar, yurtlar, restoranlar ve sosyal alanlar) elde edilen alan bazlı kullanıcı sayıları ve geri dönüştürülebilir atık üretim miktarlarına ilişkin veriler kullanılmıştır. Bu doğrultuda, GAMS (General Algebraic Modeling System) yazılımı kullanılarak; toplama noktaları ile atık işleme tesisleri arasındaki mesafeler, araç kapasite kısıtları ve taşıma maliyetlerini dikkate alan bir matematiksel model geliştirilmiş ve çözülmüştür. Modelin uygulanabilirliği incelenmiş; birden farklı senaryo analizleri kapsamında toplama rotalarının kampüs genelindeki kullanım yoğunluğuna bağlı olarak oluşan doluluk oranları, taşıma mesafeleri ve toplam maliyetler üzerindeki etkileri değerlendirilmiştir. Elde edilen sonuçlardan önerilen optimizasyon yaklaşımının toplam taşıma maliyetlerini düşürdüğünü ve kampüs içi atık toplama faaliyetlerinin daha etkin ve verimli bir şekilde yürütülmesine fayda sağladığını göstermektedir. Bu bağlamda, geliştirilen ve önerilen modelin üniversite kampüslerinde sürdürülebilir geri dönüşüm sistemlerinin planlanması ve yönetilmesi amacıyla etkin bir karar destek aracı olarak kullanılabileceği ortaya konmuştur.
