Collaborative Routing Optimization Model for Reverse Logistics of Construction and Demolition Waste from Sustainable Perspective.

The construction industry is developing rapidly along with the acceleration of urbanization but accompanied by an increased amount of construction and demolition waste (CDW). From the perspective of sustainability, the existing research has mainly focused on CDW treatment or landfill disposal, but the challenge of reverse logistics of CDW recycling that provides overall CDW route planning for multiple participants and coordinates the transportation process between multiple participants is still unclear. This paper develops an optimization model for multi-depot vehicle routing problems with time windows (MDVRPTW) for CDW transportation that is capable of coordinating involved CDW participants and suggesting a cost-effective, environment-friendly, and resource-saving transportation plan. Firstly, economic cost, environmental pollution, and social impact are discussed to establish this optimization-oriented decision model for MDVRPTW. Then, a method combined with a large neighborhood search algorithm and a local search algorithm is developed to plan the transportation route for CDW reverse logistics process. With the numerical experiments, the computational results illustrate the better performance of this proposed method than those traditional methods such as adaptive large neighborhood search algorithm or adaptive genetic algorithm. Finally, a sensitivity analysis considering time window, vehicle capacity, and carbon tax rate is conducted respectively, which provides management implications to support the decision-making of resource utilization maximization for enterprises and carbon emission management for the government.

Exploring incentive mechanism in smart e-waste management system in China

With the vast increase in global e-waste, e-waste management is becoming increasingly critical. China produces a large amount of e-waste every year, but the recycling rate is minimal. To avoid causing severe environmental pollution and affecting human health, the Chinese government has focused on recycling e-wastes. E-waste contains precious metals and critical minerals, which are misplaced resources and have recycling value. We combined the incentive system with the smart e-waste collecting system and constructed a set of incentive measures suitable for China’s smart e-waste collection system, which is conducive to enhancing the e-waste recovery rate and is applicable. The existing smart e-waste collection system adopts a single economic incentive method. It faces fierce competition from unauthorized informal recyclers, resulting in a small number of users and a failure to fully utilize its advantages. In the reverse logistics of e-waste recycling, consumers are the starting point of product recycling. By analyzing the characteristics and determinants of Chinese users’ recycling behavior, this study selected appropriate incentives for a smart e-waste collection system to satisfy Chinese consumers’ perceptions of end-of-life electrical and electronic equipment. The incentive system is based on economic incentives, including currency, reward points, and tax incentives, and combines negative incentives, mainly fines. Rewards and punishments are employed simultaneously to achieve long-term and sustainable incentive effects. The incentive system is based on the convenient infrastructure of the smart e-waste collection system, and its financial model must be shared by multiple stakeholders from the government, smart e-waste systems, and manufacturers.

Logistics of carpet recycling in the U.S.: designing the recycling network

Transportation of post-consumer carpet from collection points to recycling facilities and then to the end-users of the recycled materials contributes significantly to the final costs of recycled materials. In this article, several alternative network designs for the U.S. carpet recycling systems are developed and compared in terms of network costs. In two scenarios, these networks include layers of local collection centers, recycling plants, and markets for recycled materials. In the third scenario, a layer of regional collection centers is added before the recycling plants to aggregate carpet for more efficient sorting and transportation. To find the optimal number and locations of recycling plants and regional collection centers as well as the optimal flows among network facilities, a hierarchical facility location model is formulated that can be used for the different network configurations considered. To solve large-scale instances of the problem, a heuristic method based on the alternative location-allocation procedure is developed, and a computational study is conducted to assess its performance. The results of the study can be used by organizations involved in carpet recycling in the U.S. to establish reverse networks. In addition, the optimization model and the solution heuristic can be used for similar problems in forward or reverse logistics.

Environmental and economic advantages of adopting reverse logistics for recycling construction and demolition waste: A case study of Brazilian construction and recycling companies.

The aim of this study was to assess the economic and environmental advantages of implementing reverse logistics to recycle solid waste from construction companies. The adopted research method was based on a systematic literature review and two case studies. For the economic assessment, the return on investment, the internal rate of return, and the discounted payback factors were considered, while the material intensity factor was used for the environmental impact assessment. This study shows that there are economic and environmental advantages associated with the use of reverse logistics for solid waste treatment and recycling. In 2016, the purchase of recycled blocks resulted in a profit of over US$45,000 for one company, and another company earned almost US$250,000 in the same year by recycling solid waste from manufacturing blocks and selling iron, wood, paper, and plastics. Furthermore, the environmental impact was reduced. This paper contributes to the dissemination of knowledge regarding the advantages of adopting reverse logistics for recycling construction and demolition waste, and creates new opportunities for companies.

Logistics of carpet recycling in the U.S.: designing the collection network

Efficient collection of post-consumer carpet is an important part of the carpet recycling process that helps to reduce the cost of recycled materials as well as provide sufficient volumes of carpet for recycling facilities. This paper focuses on the design of a collection network for carpet in the U.S. The location set covering optimization model formulated in the paper allows locating the minimum number of collection centers throughout the U.S. to reach a specific level of population coverage and as a result, a target collection rate. To solve real-scale instances of the problem, a novel randomized greedy heuristic is developed. The heuristic is shown to perform better than existing greedy heuristics in the literature. In addition, the paper presents the resulting nationwide carpet collection networks for different levels of population coverage. The results of the study can be used for U.S. carpet recycling policy-making decisions.

The Analysis of the Interpretation and the Essence of Green Logistics

The article is devoted to the analysis of various interpretations of green logistics, which are similar in content and do not contradict each other, but only reflect the point of view of various experts on the same problem: recycling logistics, secondary management logistics of an enterprise, recycling logistics, waste logistics, reverse flow logistics, reverse logistics, eco-logistics, reverse supply chain management, return flow management. The lack of terminological unity makes it necessary to create a classification with regard to different definitions related to the interpretation of this concept in modern approaches to the interpretation of green logistics. The analysis of the various interpretations of green logistics found that in green logistics it is necessary to distinguish two functional areas: logistics of return flows of goods and logistics of waste (logistics of recycling).The purpose of the article is to analyze the interpretation of green logistics and to examine the essence of green logistics for solving management control problems, analyzing and effectively managing the movement of returned, damaged, expired and used goods, production and consumption waste, which starts from the point of their formation to the point of disposal or recycling reduce production waste and costs from returning goods.The objectives of the study are to create a classification of various definitions related to the interpretation of green logistics and the study of the main goal, objectives, functions and principles of green logistics.This research is conducting in the field of green logistics is very important for the conditions of Ukraine, since it is our country that is among the states with the most relative and absolute indicators of waste generation and accumulation. Therefore, the essence of green logistics considering at the micro level, it should be noted that green logistics is associated with the effective management of the flow of returned, damaged, expired and used goods, production and consumption waste both in the forward direction and in the opposite direction and will improve the results of enterprises for expense of saving material resources and reducing the expenditure indicators of the enterprise.

Economic and environmental assessment of recycling and reuse of electronic waste: Multiple case studies in Brazil and Switzerland

The increasing quantity of electronic waste is a societal problem due to the imminent risk of eco-system contamination from harmful substances present in these products. Therefore, recycling and reusing these materials could mitigate environmental impacts and provide economic gains. The present research is aimed at assessing the economic and environmental advantages of adopting Waste Electrical and Electronic Equipment (WEEE) reverse logistics for recycling and reuse by three Brazilian manufacturers of electro-electronic products,and three recyclers,two located in Brazil and one located in Switzerland. Specifically, this study maps the processes used by three recyclers. These multiple case studies incorporated both observation and semi-structured interview. The Mass Intensity Factor was used for the environmental impact assessment. We found that the adoption of electronic waste reverse logistics for recycling and reuse resulted in reduction of the environmental impact in the abiotic, biotic, water and air compartments and economic gains for the manufactures and recyclers, indicating a promising market in the Brazil. Another relevant result was the presentation of a simple eco-efficiency tool to be used in organizational practice. This tool provides a performance indicator based on indexes to implement goals for continuous recycling and reuse improvements, aimed at achieving a closed cycle. However, electronic waste recycling and reuse processes in Brazil are decentralized and, therefore, the development of a cooperation network as a whole is complex. Furthermore, precious metal recovery from printed circuit boards is a process carried out specifically by foreign enterprises because the Brazilian manufacturers and recyclers do not have enough technology due the lack of resources for investment. Thus, the Brazilian government has been holding meetings with the manufacturers and recyclers to develop a sectoral agreement in order to support financially the transfer of this technology for recycling of printed circuit boards to Brazil. In addition, this fact contributes to the National Solid Waste Policy, and it increases the financial profitability of Brazilian recyclers because with this process the recyclers could extract precious metals for sale increasing the economic gain.

ЛОГІСТИЧНИЙ ЧИННИК СТАЛОГО РОЗВИТКУ ТУРИСТСЬКИХ ТЕРИТОРІЙ (ДЕСТИНАЦІЙ) НА ПРИКЛАДІ МІСЬКОГО ТА СІЛЬСЬКОГО ТУРИЗМУ

Revealed logistical approach to achieve sustainable development of urban and rural kinds of tourism including practical examples of the most popular tourist destinations (cities) in Ukraine – Kyiv and Lviv. Logistics approach is based on applying the concept of spatial regulation of tourist flows in cities and rural areas (worked out by one of authors – Smyrnov I.G.) and the concept of reverse logistics for recycling of waste, which volume increases as usual after tourists visits. Fulfilled comparison of logistical features of urban and rural tourism in order to ensure their sustainability. For a common goal – to achieve sustainability of the tourism industry in a particular area and at the same functional purpose – by optimization (regulation) of tourist flows in appropriate way to the specific destinations considering their tourism resource base and distribution of tourist flows differences lie in the different resource base for tourism development. In the case of rural tourism resource base is: first, the landscape (natural landscapes); second, flora and fauna; third, agricultural production; fourth, various events (ethnographic, ethnomusic, ethnogastronomic and other ethnotouristic holidays and festivals). In the case of urban tourism the resource base is equally varied and includes: first, historical and modern buildings and other points of architectural interest; second, interurban objects (castles, museums, shopping and entertainment centers etc.); third, the natural environment (parks, botanical gardens etc.); fourth, various events (international, national, city celebrations, festivals and other social and cultural activities). There is difference in the case of rural and urban tourist flows distribution along the territory: typical for rural tourism is dispersing distribution (on farms), typical for urban tourism is concentrated distribution, particularly in the central and historic districts of cities. Accordingly major logistical tasks of ensuring the sustainability of tourism are also different: for rural tourism it is, first, to determine minimum and maximum volumes of tourist flows; second, is desired the waste recycling and monitoring of environmental conditions. For urban tourism main task is to determine the maximum tourist flows volume and as a must the waste recycling whith improving of environmental conditions. Also developed scientific and practical grounds of reverse ecologistics, i.e. logistics of waste recycling remaining after the tourists stay in urban and rural destinations. Proposed mathematical approach of ecologistical optimization of waste reusing (recycling) in destinations of urban and rural tourism.

Determinants and logistics of e-waste recycling

Purpose – The rapid consumption of new electronic devices has expanded the volume of electronic waste (e-waste) and created a potential threat to the environment. Recycling of e-waste (eCycling) can help stem the proliferation of e-waste and its environmental threat. In order to increase this positive involvement in eCycling and design effective eCycling programs, a better understanding of eCycling behaviors is needed. The purpose of this paper is to employ the Theory of Reasoned Action as a framework to develop a model to identify the determinants of eCycling behavior. Design/methodology/approach – To assess the model, a survey of 327 university students is undertaken. To analyze the eCycling behavior from the survey data, a structural equation modeling technique is used. Findings – The findings suggest that: attitudes and moral norms positively influence eCycling behavior; the higher the awareness of consequences, the more the eCycling involvement; and perceived convenience is an important factor that leads to more involvement in eCycling. Research limitations/implications – This research is limited by the student sample and campus environment that might confine the generalizability of the study. Also, additional variables need to be examined in order to better explain eCycling behavior. The result of the study provides insights for organizations to build successful eCycling programs, engage young adults such as college students in eCycling, and increase involvement in eCycling. Practical implications – This study provides insights that can help supply chain managers to better understand the consumer involvement in eCycling. Managers’ understanding of eCycling behavior would encourage eCycling involvement by placing drop-off units in convenient locations and by creating campaigns that motivate consumers to return their e-waste. An increased consumer involvement in eCycling can help manufacturing companies lower the cost of e-waste across the supply chain and regain the value of returned materials by adopting reverse logistics. Originality/value – This study contributes to the stream of eCycling literature by investigating students’ eCycling intentions and behaviors on a university campus. The paper develops an understanding of how eCycling involvement might be improved.

An Optimization Model for Expired Drug Recycling Logistics Networks and Government Subsidy Policy Design Based on Tri-level Programming.

In order to recycle and dispose of all people’s expired drugs, the government should design a subsidy policy to stimulate users to return their expired drugs, and drug-stores should take the responsibility of recycling expired drugs, in other words, to be recycling stations. For this purpose it is necessary for the government to select the right recycling stations and treatment stations to optimize the expired drug recycling logistics network and minimize the total costs of recycling and disposal. This paper establishes a tri-level programming model to study how the government can optimize an expired drug recycling logistics network and the appropriate subsidy policies. Furthermore, a Hybrid Genetic Simulated Annealing Algorithm (HGSAA) is proposed to search for the optimal solution of the model. An experiment is discussed to illustrate the good quality of the recycling logistics network and government subsides obtained by the HGSAA. The HGSAA is proven to have the ability to converge on the global optimal solution, and to act as an effective algorithm for solving the optimization problem of expired drug recycling logistics network and government subsidies.
