The hazardous waste location and routing problem: an application in Marmara Region in Turkey

Abstract

Hazardous waste management involves the collection, transportation, processing, recycling and disposal of industrial and domestic wastes. In this study, a single objective, multi-product mixed integer programming model for hazardous waste facility location and routing problem is developed for the hazardous waste management problem. The aim of the study is to locate hazardous waste treatment, recycling and disposal facilities to the designated candidate locations with the lowest cost and highest profit. With this, we try to ensure that the waste is transported between hazardous waste generation centers and these facilities with the minimum cost and maximum revenue. Unlike the studies in the literature, we constructed an enhanced model that take all the following properties into account: the location of hazardous waste treatment, recycling and disposal facilities; transportation of hazardous waste, hazardous recycled materials and hazardous waste residues between these facilities; cost, revenue, risk, capacity and technology compatibility. The model provides to decide the sorts of facilities which are needed by considering the type and amount of hazardous waste generated in determining where to locate these facilities. The model, also, determines which types of hazardous waste can be transported between the facilities. The developed model is applied to the Marmara Region with the real data provided by the Republic of Turkey Ministry of Environment and Urbanization. Accordingly, the results are evaluated and presented.

Towards the circular economy: Analysis of barriers to implementation of Turkey’s zero waste management using the fuzzy DEMATEL method

“…In Turkey, many studies have intensively examined municipal solid waste management (Ayvaz-Cavdaroglu et al, 2019; Banar et al, 2009; Coban et al, 2018; Tınmaz and Demir, 2006; Turan et al, 2009; Rızvanoğlu et al, 2019). Furthermore, some researchers studied liquid waste (Gurbuz and Ozkan, 2019), medical waste management (Birpınar et al, 2009), hazardous waste (Utku and Erol, 2020; Yayintas et al, 2007) and food waste (Cakar et al, 2020). In the light of the literature, none of the studies has examined the challenges and difficulties of municipal waste in accordance with the zero waste strategies in Turkey.…”

Analyzing the Vulnerabilities in a Transshipment Network: A Bilevel Programming Approach

“…Here, an external player in conflict with the network runner tries to maximize the function. The courses of action for the opponent are defined by constraint (31) and constraint (32) in the outer model. Constraint (31) defines the intervenor's resource limitation, and constraint (32) describes binary decision variables y's, which indicate whether a specific segment is disabled by the opponent.…”

“…There are some studies quantitatively identifying the risk and suggesting mitigating strategies in the networks having potential life and environmental risks. Among those, Yin et al [39], Utku and Soyöz [33], and Utku and Erol [32] propose a hazardous material (hazmat) transportation network design model to decrease the risk in transportation. Zhang et al [40] suggest a model to determine the risk factors of hazmat crashes on a macro level and develop appropriate measures for improving hazmat transportation safety.…”

An Application: A Multi-Mode Natural Gas and Liquefied Natural Gas Supply Chain Management Problem

“…(2020) use the Full Consistency Method for the supplier selection and Ali et al ( 2021) study a complex interval-valued Pythagorean fuzzy set (CIVPFS) for the green supplier chain management. To cope with the uncertain demand for a waste recycling supply chain, Giri et al (2020), Utku and Erol (2020), and Samanta and Giri (2021) propose models for recycling, waste management including recycling, and a two-echelon supply chain model for a single vendor and buyer, respectively.…”
