Abstract Waste collection management is considered as one of the important issues in sustainable logistics design which is one of the new concepts in supply chain management. In recent years, researchers’ attentions are attracted to apply green and sustainable concepts in their researches. This paper presents a novel multi-objective mathematical model considering a new collection network for waste collection problem. We are interested in the location decisions in design phase of the network and waste collection decisions in operational phase. The problem consists of activities related to collection, treatment, recycling, and disposal of hazardous wastes in multi stage network. Three objective functions including operational cost and social costs are considered, simultaneously. The model is used to evaluate fuel consumption and carbon dioxide emission and its impact on environment. A new hybrid meta-heuristic algorithm is designed to solve the problem and a new way to represent solutions is provided. Finally, experimental results are conducted and the results obtained by proposed algorithm are compared to four well-known meta-heuristic algorithms with respect to five comparison metrics. The results show the efficiency of proposed algorithm in some comparison metrics. Keywords Metaheuristic algorithm · Multi-objective · Waste collection · Sustainable logistics · Location routing problem (LRP) Mathematical Subject Classification 90B06 · 90B50 · 90B80

1 Introduction Sustainable logistics is one of the novel concepts in supply chain management. In recent years, researchers’ attentions are attracted to apply green and satiability in their researches. Some Governments and non-Government organizations oblige logistic companies to address environmental issues in their strategic decisions. Earlier works in Supply Chain Management (SCM) concentrated on economical issues more than other issues, but the trend of researches shows that environmental issues have been considered further in recent years (Sbihi and Eglese 2007). Sustainability can be defined as the ability of enhancing the quality of human life with simultaneous consideration of activities related to protection of environment (Sbihi and Eglese 2007). According to the world commission on environment and development (termed Brundtland) definition, sustainability is “the potency to meet the present needs of human without disruption and damage to capability of next generati
