A nationwide regulation requiring shops to charge customers for plastic bags has educated Chinese consumers to the detrimental environmental impact of such bags and enhanced the popularity of reusable shopping bags. However, plastic bags remain ubiquitous since they are useful and shoppers often forget to bring their own bags to the shops. Moreover, the public still view shopping bags as disposable items, so they typically neglect to clean their reusable bags. Our project seeks to reduce this waste and the related environmental impact by making it easier for shoppers to use and recycle reusable shopping bags. We will set up ‘Reusable Bag Centres’ in high-density traffic areas near supermarkets, housing compounds and university dormitories where we will supply clean, recycled and reusable shopping bags. At these centres, shoppers will be able to obtain free reusable shopping bags and tokens which they can use to exchange their dirty reusable bags for ones that have been cleaned and sterilised. We intend to recycle the bags once a week and sterilise them every two weeks. The project will be carried out in the Guangzhou Higher Education Mega Center, a suburb of Guangzhou in which many university campuses are located.
