“…Approximately 6–8% of the global production of fossil fuel goes into the synthesis of plastic materials such as polyolefin, polystyrenes, polyesters or polyamides. However, the environmental concerns about the lack on biodegradability have led to an increased interest in the development of green plastics and composite materials derived from renewable natural resources with distinct or superior physical and chemical properties [4,5,6].…”

HDPE/Chitosan Composites Modified with PE-g-MA. Thermal, Morphological and Antibacterial Analysis

et al. 2019

In this work, composites of high density polyethylene (HDPE) with chitosan were prepared by melt compounding in a laboratory internal mixer. Maleic anhydride grafted HDPE (PE-g-MA) in a concentration up to 25 phr was used as a compatibilizer to enhance the dispersing effect of chitosan in the HDPE matrix. The degree of crystallinity was investigated by X-ray diffraction (XRD) and the thermal properties were analyzed by differential scanning calorimetry (DSC) and thermogravimetry (TG). The morphology was investigated by optical microscopy (OM) and scanning electron microscopy (SEM). The integrity of composites was evaluated by mechanical properties and antibacterial properties were assessed against Escherichia coli (DH5a). Neither crystallinity nor HDPE’s melting parameters changed upon addition of chitosan and PE-g-MA. Chitosan aggregates were observed, which were dispersed upon addition of PE-g-MA, which also provided improved mechanical performance. Chitosan significantly improved the bacteriostatic effect of HDPE compounds preventing bacteria to colonize thus reducing the number of viable colony-forming units (CFU). This study revealed that HDPE/chitosan composites could be obtained by melt compounding, at lower cost and additionally having antibacterial properties, which might provide a new formulation option for developing antimicrobial film for food packaging.

“…An example of a new type of bio-based plastic is Polyethylene Furanoate or PEF, which is expected to reach consumers in the next few years. PEF, for instance, has a carbon footprint that is less than half of that of conventional plastic [43%-56% reduction in CO2 emissions, 11,12].…”

“…Again, this was done using a slider measure, this time reaching from £0 ('I don't want to donate') to £0.85 (the amount they received for participating in the study). As in the previous studies, we ran a paired-sampled t-tests 12 comparing participants' general attitudes (collapsed across all conditions) towards conventional and bio-based plastic 13 . Participants felt much more favourable towards bio-based plastic than towards conventional plastic, t(303) = -15.00, p < .001, d = -0.86 (for means and standard errors see Figure 1, Study 4).…”

Fossil-based plastics are significant contributors to global warming through CO2 emissions. For more sustainable alternatives to be successful, it is important to ensure that consumers become aware of the benefits of innovations such as bio-based plastics, in order to create demand and a willingness to initially pay more. In four studies, we investigated participants’ attitudes towards fossil-based and bio-based plastic, their perceived importance of recycling both types of plastic, their willingness to pay, and their perceptions of bio-based plastic. The pre-registered fourth study experimentally manipulated information about bio-based plastic and measured willingness to pay for different types of plastic. The results suggest participants hold very favourable attitudes and are willing to pay more for bio-based products. However, they also harbour misconceptions, especially overestimating bio-based plastic’s biodegradability, and they find it less important to recycle bio-based than fossil-based plastic. Study 4 provided evidence that educating consumers about the properties of bio-based plastic can dispel misconceptions, retain a favourable attitude and a high willingness to pay. We found mixed evidence for the effect of attitudes on willingness to pay. We discuss how attitudes and misconceptions affect the uptake of new sustainable technologies such as bio-based plastics and consumers’ willingness to purchase them.

PET-Bottled Water Consumption in View of a Circular Economy: The Case Study of Salento (South Italy)

et al. 2020

Polyethylenterephtalate (PET) is the preferred packaging material in the bottled water industry and represents the main cause of waste production. This work investigated the drinking water consumption habits, with particular reference to PET-bottled water, of people living in the province of Lecce (Apulia Region, Southern Italy) by age and geographical groups. Their perception about the quality of tap water was also explored. The survey was performed by the administration of a questionnaire to 4137 citizens. Bottled mineral water was consumed by about the 90.4% of respondents with an average consumption of 387.7 L/year per capita (375.2 L/year in PET-bottles, 12.5 L/year in glass bottles). Public supply system was used by the 61.5% of respondents with an average consumption of 169.4 L/year per capita. The consumption of tap water was negatively related to the perception of its bad quality and the residence in a big city (Lecce); while it was positively associated with the age group ≤16 years old. Effective communications strategies must be developed in order to promote the consumption of tap water and implement good practice of circular economy.
