“…The molecular-docking approach is based on the lock-and-key principle, which is used for binding small ligand molecules to receptor proteins [ 59 ]. The space shape and energy between the ligand and acceptor during docking should be matched to obtain the most stable binding conformation [ 60 ]. Rubber is a polymer compound but its structure is not complex and is usually formed by specific structural units linked hundreds or thousands of times by covalent bonds.…”

Tire polymers (TPs) are the most prevalent type of microplastics and are of great concern due to their potential environmental risks. This study aims to determine the toxicity of TPs with the help of molecular-dynamics simulations of their interactions with receptors and to highlight the differences in the toxicity characteristics of TPs in different environmental media (marine environment, freshwater environment, soil environment). For this purpose, five TPs—natural rubber, styrene–butadiene rubber (SBR), butadiene rubber, nitrile–butadiene rubber, and isobutylene–isoprene rubber—were analyzed. Molecular-dynamics calculations were conducted on their binding energies to neurotoxic, developmental, and reproductive receptors of various organisms to characterize the toxic effects of the five TPs. The organisms included freshwater species (freshwater nematodes, snails, shrimp, and freshwater fish), marine species (marine nematodes, mussels, crab, and marine fish), and soil species (soil nematodes, springtails, earthworms, and spiders). A multilevel empowerment method was used to determine the bio-toxicity of the TPs in various environmental media. A coupled-normalization method–principal-component analysis–factor-analysis weighting method—was used to calculate the weights of the TP toxicity (first level) categories. The results revealed that the TPs were the most biologically neurotoxic to three environmental media (20.79% and 10.57% higher compared with developmental and reproductive toxicity, respectively). Regarding the effects of TPs on organisms in various environmental media (second level), using a subjective empowerment approach, a gradual increase in toxicity was observed with increasing trophic levels due to the enrichment of TPs and the feeding behavior of organisms. TPs had the greatest influence in the freshwater-environment organisms according to the subjective empowerment approach employed to weight the three environmental media (third level). Therefore, using the minimum-value method coupled with the feature-aggregation method, the interval-deflation method coupled with the entropy-weighting method, and the standard-deviation normalization method, the three toxicity characteristics of SBR in three environmental media and four organisms were determined. SBR was found to have the greatest impact on the overall toxicity of the freshwater environment (12.38% and 9.33% higher than the marine and soil environments, respectively). The greatest contribution to neurotoxicity (26.01% and 15.95% higher than developmental and reproductive toxicity, respectively) and the greatest impact on snails and shrimp among organisms in the freshwater environment were observed. The causes of the heterogeneity of SBR’s toxicity were elucidated using amino-acid-residue analysis. SBR primarily interacted with toxic receptors through van der Waals, hydrophobic, π-π, and π-sigma interactions, and the more stable the binding, the more toxic the effect. The toxicity characteristics of TMPs to various organisms in different environments identified in this paper provide a theoretical basis for subsequent studies on the prevention and control of TMPs in the environment.

“…In these communications, corporations not only engage the consumer but also invoke the consumer as the figure for whom they act (Evans et al, 2017;Cherrier and Türe, 2022). In this manner, the expansion of warning plastic labels including "plastic containing BPA," "PET plastic," "made with Bisphenol A" and the development of new markers for ("reusable") plastic packaging (Van Asselt et al, 2022) or plastic bottles (Burrows et al, 2022) impose a responsibility for consumers to become informed, to carefully read labels, and to make choices in accordance with their willingness to bear risks for their health and for the environment (Mykitiuk, 2002;Giesler and Veresiu, 2014;Cherrier and Türe, 2022;Döbbe and Cederberg, 2023). In this manner, "when we see discarded plastic bags, bottles or food packages, we can relate our own use of the same objects to potential consequences" (Nielsen et al, 2019, p. 6).…”

This paper highlights the limitations of the use of risk in plastic governance. First, plastic risk categorizations adapt, evolve, and shift, which creates ambiguities and insecurities for consumers about the responsible choices to be made. Second, the risk frame requires consumer agency to mitigate risk, a privilege many cannot afford. Third, the use of risk in plastic governance cedes power to dominant market actors who possess the capacity to blame others and use guilt appeal to alleviate their responsibility. The concluding remarks point to the importance of changing our minds about plastics. The argument is to stop thinking that plastics are flexible and malleable.

“…A systematic review of the literature on "environmentally friendly food packaging" reports that in most of the studies analyzed, consumers were willing to pay more for such packaging (Ketelsen et al, 2020). On the other hand, a logo warning of the plastic pollution caused by packaging can reduce consumers' WTP (Van Asselt et al, 2022). However, another Canadian study obtains that the WTP for cereal bars in cardboard packaging with environmental certification does not make consumers want to pay more (Ertz et al, 2017).…”

“…However, offering milk in a returnable glass container is a reason to pay more (Neill and Williams, 2016). In addition, consumer interest in organic produce may encourage the purchase of fruit and vegetables without packaging (van Herpen et al, 2016). Finally, the fact that consumers must pay more for eco-responsible packaging (including bulk products) encourages them to prefer the sustainable packaging option to bulk products, when they have the choice (De Canio, 2023).…”

Consumer interest and willingness to pay for in-bulk products with reusable packaging options

Consumers are looking for solutions to reduce waste at source, especially plastic waste from single-use packaging. Simply recycling packaging will not be enough and reduction at the source must be emphasized as part of a sustainable circular economy. Selling products in bulk using reusable containers is one of the emerging paths of the zero waste movement. To achieve this, it is necessary to change consumption patterns and behaviors. Our goal is to better understand how source reduction of plastic packaging can be an asset in a zero waste objective. Using a contingent valuation method, we conducted a large pan-Canadian survey on the purchasing preferences of 2002 Canadian households to analyze the willingness to pay (WTP) for different food and household products. Results indicate that most consumers do not appear to be willing to pay more for bulk products with reusable packaging even if they are interested in buying more bulk products. Different socio-demographic and attitudinal parameters, such as age, gender, sense of convenience, and pro-environmental behaviors, influence willingness to buy and pay. The originality of this work is to provide an economic perspective on the reduction of single-use containers and changes in consumption practices in the context of the zero waste movement and the circular economy.
