The Role of Environmental Factors in the Investment Prioritization of Facilities Using Recycled PVC

Abstract

There are many types of solid wastes however, plastic wastes are among the ones which have several harmful effects on the environment. Plastic wastes have a long decomposition time in nature and the dangerous chemical compounds in them make them a threat for the environment along with other types of waste. Contamination caused by the plastic wastes attracts worldwide attention nowadays. As a member of thermoplastic polymers family, polyvinyl chloride (PVC) products are one of the most preferred type of plastic composition, which holds an important ratio in the total plastic waste amount. PVC wastes should either be disposed or recycled to minimize their harmful effects on the environment. The disposal approach is easy and cheap, but recycling alternative requires the investment on special facilities hence, a more expensive solution. However, disposal alternatives, such as landfilling and incineration, may also cause pollution due to high chlorine content of PVC; whereas, mechanical and chemical recycling options reduce many environmental problems. There is a clear tradeoff in the decision of handling PVC waste between the costs and environmental effects. The purpose of this study is to evaluate the factors considered during the investment decisions of PVC manufacturers to find out the importance of environmental factors by using a multi-criteria group decision making method.

Strategic Alignment of Management Information System Functions for Manufacturing and Service Industries with an F-MCGDM Model

“…Among the wide range of methodologies developed throughout the years, the Analytical Hierarchy Process (AHP) is still preferred in recent studies because of its accuracy [29]. AHP has a more than 65% preference rate among authors in the literature [30].…”

“…However, there are no consistency control or group decision aggregation steps embodied in the FAHP algorithm. Hence, in the framework of this study, AHP consistency ratio calculation steps were implemented first to ensure that the consistencies of all individual DM evaluations are satisfied [29,56,65]. Second, calculation steps of the aggregated group decision matrix are added to the FAHP algorithm to propose the F-MCGDM framework that uses TFN and FAHP as the evaluation model of the study.…”

“…Step 5: According to group decision-making rules, l number of individual DM evaluations should be aggregated using geometric means to form the initial group decision matrix before proceeding to MCDM analysis [29]. The inclusion of this operation converts the model into the MCGDM model.…”

Sustainable Alternatives to Nondegradable Medical Plastics

“…However, several studies have shown that chemical recycling incurs a higher cost compared to other recycling processes (e.g., mechanical recycling, incineration), primarily owing to the low value of the recovered products. For example, recycling PVC will generate hydrochloric acid (HCl), and an additional step and cost are required to replace the same . Thus, chemical recycling for PVC might not be a cost-efficient option.…”

Study on the Sorting Process on the Basis of the Effect of Shrinkage and Melting of Plastics and Its Impact on Further Processing of the Materials

“…It is indicated that the share of these products in relation to all plastic materials produced in the world is 36% [2]. The types of plastics most commonly used in packaging products include: high and low density polyethylene (HDPE and LDPE), polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS) and polyvinyl chloride (PVC) [2,3]. The most commonly used polyethylene, both HD and LD, in Europe accounted for almost 30% of all plastics produced in 2018 [4].…”
