University of Wolverhampton. https://wlv.openrepository.com/handle/2436/625936https://wlv.openrepository.com/handle/2436/625936A thesis submitted in partial fulfilment of the requirements of the University of Wolverhampton for the degree of Doctor of Philosophy.Retail industries use an enormous number of plastics, especially packaging. "Reverse Shopping," that is, the returning of branded plastic packaging to the point of purchase (respective retail brands) by deploying blockchain with smart contracts, is our research focus. Employing a local blockchain, implemented in a basic format to store records of collected plastic packaging matched by the smart contract when returned, which also incorporates a reward mechanism courtesy of digital 'coin offerings' (cryptocurrency). To date, both blockchain and smart contracts are operationally standalone in this regard. We are proposing an innovative design model that advocates for (a) Including reverse shopping on retail industries' branded plastic packaging (as opposed to third-party collection points, such as recycling bins). (b) Fostering a 'reverse order' between retailers and manufacturers, like that between retailers and consumers. (c) Aid ethical and transparent sustainability.application/pdfenblockchainsmart contractreverse shoppingretail industryplasticpackagingcircular economyplastic packagingThesis or dissertation
