Drivers of single-use plastic waste generation: lessons from packaged water consumers in Ghana

Single-use plastic waste have become ubiquitous in the natural environment globally. In Ghana, the drinking water sector has become heavily dependent on packaged water in the form of sachet and bottled water. This has resulted in increased generation of single-use plastic waste littered in the natural environment. Waste sachets, though still major a challenge, have received some attention over the years in terms of identifying solutions for sustainable management. On the other hand, limited studies have focused on waste plastic bottles in terms of their generation, disposal and options for sustainable management. This study sought to explore the socio-demographic and attitudinal drivers of bottled water consumption in Ayawaso West Municipal Area located in the Greater Accra Region of Ghana. The results showed that increasing income levels, perceptions of hygiene and safety as well as convenience were the main factors driving the patronage of bottled water. Bottled water consumption is expected to continue to rise in coming years in response to rising income levels. Residents showed willingness to engage in waste segregation of their plastics however limited waste collection systems are available to support this. It is important to prioritize the waste plastic bottles in the waste management agenda and offer households waste collection options that will make segregation of waste worthwhile and sustainable.
