Hi Greg, thank you for your response.
This projects primary focus is to provide communities in developing countries a way of transforming household waste into a useful resource, or income.
The solution will be constructed mostly using locally sourced materials including used plastic barrels, plastic tubing and requiring only basic hand tools to assemble.
When used to its full potential, the solution will generate great quality fertiliser within 21 days. It does this using a few key principles:
Aeration - Daily movement/mixing to ensure bacteria circulates through waste.
Temperature - Between 30-50 degrees C ensures thermophilic reaction occurs. This kills any pathogens in the animal and human waste.
Odour Control - Using sawdust/wood shavings, any odour produced by the waste is contained. This is particularly important where human/animal waste is being composted. This will also prevent methane from being produced.
If the following principles are applied, households will be able to produce around 30kg of compost per month. In Mumbai, India, this would have a value of $10, which is equals the average monthly income. Alternatively this fertiliser can be used to grow their own vegetables, which would save them money as well as being an educational tool.
The short survey I've included in my original post relates to the idea of having a secondary market, which would allow those in western countries to adopt the same principles in order to remove the need for food waste bins.
I hope this helps. Let me know if you have any other questions or ideas and I'd happily discuss these further.
Many thanks
Sam
