When it comes to enhancing the sustainability of plastic beverage bottles, consumers are willing to pay a bonus for bio-based alternatives—the more so when the alternative is visually distinctive. This follows from research by Ph.D. candidate Maria Zwicker as part of the RIBIPOL project where novel rigid bio-based polyesters are being developed for potential large scale applications, such as beverage bottles. Her findings have been published in the January issue of the journal Sustainable Production and Consumption.
