BadBox is the container that holds faeces inside the toilet for Container-Based Sanitation services. Current containers are often products that are readily available in the local market. Such generic containers have a number of problems around: safety, usability, and economic viability. BadBox is a biodigestable container made out of dense cardboard and bioplastics. BadBox can be unfolded at the point-of-use, sealed when full, transported in a safe and modular manner, and added directly to the composting processes. BadBox keeps end users as well as delivery personnel safe and healthy. BadBox is made from waste plant material, utilising further biological waste. BadBox production will create jobs, while helping waste service providers to scale profitably.
