After a large number of iterations and long days at the workbench there are three prototypes ready to be tested in Kenya. They each test different hypotheses around assembly, use, closing, and transport. These prototypes are intended to test usability factors, and are not biodegradable.
Today is the first day working at Impact Hub Zurich. Big tables, lots of light and a collaborative atmosphere are making for a productive day. Sexy Salad was excellent as always. Impact Hub Zurich is both a great co-working space and a center for social enterprise! There will be many unforeseen opportunities working in this space will bring!
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.
In informal settlements, where municipal sanitation does not exist, residents often use unhygienic and unsafe communal pit latrines, paying a small fee for every use. One solution is Container-Based Sanitation services, where users rent a toilet from the service provider in their homes. A container within the toilet holds the faeces and is replaced weekly, then transported to a central processing site where the faeces is processed into compost, fertiliser, fuel, or biogas. At equivalent or lower prices to a communal latrine, users have a clean, safe, user-friendly private toilet.
Some Container-based sanitation providers worth checking out are:
Container-based sanitation (CBS) – in which wastes are captured in sealable containers that are then transported to treatment facilities – is an alternative sanitation option in urban areas where on-site sanitation and sewerage are infeasible. This paper presents the results of a pilot household CBS service in Cap Haitien, Haiti.
