Most of the construction materials still go to landfill after structures are demolished. This causes issues in human health, ecosystem preservation, and excessive resource consumption compared to RL options. Hence, recovering material value through reverse logistics (RL) is important to lessen the environmental and social burden. Embodying RL practices into strategic level decisions derives long-term and sustainable advantages. Although the most common RL option in construction seems to be recycling, it requires an additional energy and material intensive process. Therefore, recycling should be the last preference among other RL options. The hypothesis of this study is that alternative RL strategies provide more environmental benefits than recycling, the most common RL method, and traditional landfilling. The hypothesis was tested through assessment of the environmental impact of RL options in the construction sector. A life cycle assessment (LCA) with ReCipe2016 Midpoint and Endpoint assessment method was conducted for a bridge construction supply chain. Different end-of-life scenarios such as reuse, remanufacture, recycle, and landfill scenarios were assessed using SimaPro software. This paper addresses a key knowledge gap on the environmental impact of reverse logistics strategies from a construction supply chain perspective. The research results reveal that “reuse” strategy has the least environmental impact, remanufacturing has a lesser impact on the environment than other options, recycling has the second highest environmental impact, with landfill assessed as the least environmentally friendly end-of-life option. Consequently, this paper emphasizes the importance of informed strategic supply chain decisions for reverse logistics to obtain the best outcome from environmentally friendly practices. Since there is no relevant previous research conducted to examine the environmental impact of different reverse logistics options from a construction supply chain perspective, the findings of this study provide crucial input in RL decision making and can extend to contributing to practice. Industry stakeholders, especially the government agencies and regulatory bodies, should encourage practitioners to adopt the most effective RL approaches, including reuse and remanufacturing, rather than focusing only on material recycling. The motivation of supportive designs for more environmentally friendly RL options from the researchers, designers, architects, and planners are required in this process.

Decision Making Model

Purpose Supply chain management (SCM) focuses smart logistics and quality service. Diverse elements such as design, procurement, production and sale policies are the keys to SCM efficiency. Due to worsening environmental pollution in recent years, many businesses, government agencies and consumers have become more aware of greenhouse gases (GHG) emissions. In response, the government has established new environmental regulations to control various GHG, such as CO2 and sulfur dioxide. Therefore, to reduce pollution and its adverse effects, the authors have promoted environmental concerns by developing environmental friendly policies. The purpose of this paper is to develop a multi-objective decision making model that integrates both forward and reverse logistics to determine how best to incorporate recycling and reduce manufacturing costs. Design/methodology/approach In this study, the authors developed a multi-objective decision-making model that integrates both forward and reverse logistics to determine how best to incorporate recycling and reduce manufacturing costs. They used the normalized normal constraint method as proposed by Messac et al. (2003) to generate a series of uniform lines on a Pareto Frontier chart. Findings Based on the results of this study, the authors can determine the trade-off between costs and emissions and design the most environmental-friendly and economical strategy for production. Research limitations/implications This study is limited to a case study on paper manufacturing. Practical implications The authors considered the full truckload discount policy in which buyers can reduce their purchase costs by increasing the number of full truckload product orders; this will reduce transportation costs and also minimize overall carbon emissions. Social implications This study encourages industries to focus on environmental friend policies and social responsibilities. Originality/value The authors investigated the impacts of the paper making industry on economy and environment. An increase in demand will negatively impact the environment by causing CO2 emissions to increase from higher production and the felling of more trees to provide raw materials for manufacturers (paper mills).

The purpose of this paper is to investigate environmental performance of a supply chain which consists of an upstream supplier and a downstream firm. A mathematical model considering both downstream firm’s monitoring and governmental intervention is developed. Afterwards, a numerical example is presented to show the equilibriums of these models and the optimal choices of firms and government. The results show that when customers’ environmental awareness increases, both total environmental impact and social welfare decrease. The downstream firm’s monitoring will certainly reduce the total environmental impact. In most cases, it does not matter whether the downstream firm chooses to monitor the supplier or not, the total environmental impact and social welfare would not be affected when the government chooses subsidy. If a subsidy is present, firms and environment will be better than those without subsidy. Hence, the government is more likely to choose to provide subsidy and the downstream firm will not monitor the supplier’s greenhouse gas (GHG) emissions reduction effort. In a few cases when environmental impact is too large, taxation may be the optimal choice for the government and the downstream firm will choose to monitor the supplier’s GHG emissions reduction investment.

The paper discusses characterising features of the end-of-life vehicles EU regulation, with account of the process transparency and knowledge build-up, to tailor economic instruments with reverse logistics profitability. In the short future, these issues will affect the automotive market, and the recovery (reuse/recycle) targets will become competition prerequisites for the carmakers survival. For explanatory purposes, the investigation is especially limited to consider the dismantling facility, with, in foreground, facts and technicalities arising at local and regional scales, and, in background, the whole forward and backward supply chain and related logistics problems. The basic technicalities, leading to the build-up of the reference knowledge for the most effective setting of car-dismantling facilities, are explored by means of simulation results. These lead to consider to develop automotive systems with recovery in mind, according to the carmakers responsibility for the free-take-back of the end-of-life vehicles.

Taking government environmental regulation and consumer’s green preference into a unified analytical framework, this study constructed a differential game model. With the joint effect of supplier and manufacturer green innovation efforts on the dynamic change of the product’s green level, it compared and analyzed the long-term dynamic equilibrium strategies of green innovation cooperation in a supply chain under decentralized and centralized decision-making situations. Accordingly, a scientific and reasonable profit-distribution contract was then proposed. On this basis, it further carried out a numerical simulation analysis on the dual-driving effects of the government and market. The results showed that the scientific and reasonable profit-distribution contract under the centralized decision-making situation, which was designed by using the Rubinstein bargaining game model, could effectively ensure that the supply chain members’ sharing profits would realize "Dual Pareto Improvements." With the increase of the environmental regulation’s intensity, the product’s green level kept rising and tended to be stable. However, the overall equilibrium profit of the supply chain was characterized by "U" fluctuation, which first descended and then ascended. In addition, the product’s green level, the green innovation investment and equilibrium (distributed) profits of supply chain members, and the overall profits of supply chain all increased with the consumers’ green preference.

Nuanced Understanding

This paper contributes to a less-studied area on how a firm’s position in the supply chain influences triple-bottom-line considerations in strategic decision making. We also contribute to previous research on a nuanced understanding of unabsorbed organisational slack as an antecedent to the triple-bottom-line dimensions of sustainability. The research data comprises survey data and financial reporting data from 508 manufacturing and trading firms operating in Finland, divided among four supply chain tiers. The economic dimension dominates the decision making on all tiers, followed by social and environmental considerations, resembling the shape of Mickey Mouse. Unabsorbed organisational slack is negatively related to the importance of economic considerations and positively related to environmental considerations. The results help firms in evaluating their position in terms of sustainability and in their redesigning efforts accordingly. The findings will also be useful in terms of promoting sustainability practices among supply chain members and policymakers in their practical efforts towards sustainable development.
