Challenge Statement

Circular Systems: How can we design closed-loop systems that incentivize  and utilize improved collection, or responsible disposal approaches (based on the 3Rs) of plastics within the WASH value chain?

Background Context

Ghana faces a mounting crisis regarding plastic waste, particularly single-use plastics which are pervasive across many sectors. In the Water, Sanitation, and Hygiene (WASH) sector. Despite efforts to manage waste, single-use plastics (such as water sachets, plastic packaging, and disposable hygiene products) continue to clog drainage systems and contaminate water bodies. This environmental mismanagement poses a direct threat to the climate, as non-biodegradable waste contributes to greenhouse gas emissions and the pollution of the environmental media (air, water and soil).

This crisis has major impacts on children. Poor plastic waste management leads to blocked gutters and stagnant water, which become breeding grounds for disease-carrying mosquitoes, increasing the risk of malaria and other water-borne illnesses, while air pollution contributes to the increasing incidence of Respiratory Tract Infections (RTIs). Furthermore, the degradation of plastics into microplastics threatens the long-term food and water security of vulnerable households. Current disposal models and practices are insufficient; there is an urgent need to pivot towards circular economy models by replacing single-use habits with sustainable, scalable alternatives (including re-use, reduction/ replacement and recycling (the 3Rs)), while simultaneously leveraging Social and Behaviour Change (SBC) strategies to reshape community consumption patterns.
