Urban Batch Anaerobic Biodigester

Open Biotecture

In recent days, the Open Biotecture team has been working to develop a portable bio-digester for urban area.

There is an increasing demand for organic waste management in Kathmandu, and some residents have asked us about cost-effective solutions. Currently, the residents of Kathmandu dispose their organic waste in the streets or pay for door-to-door waste collection services. For the latter, the monthly cost ranges anywhere between 200-500 NPR.

Is Portable Anaerobic Bio-digester a good idea?

Open Biotecture investigated existing solutions for treating organic waste in urban areas. The first consideration was given to aerobic composting, however, the process only produces fertiliser as an output. Also, prejudice regarding bad smells emanating from compost bins was considered a strong disincentive to make composting a valued solution.

Instead, we looked at the possibility of creating portable anaerobic biodigesters to process the waste while producing a certain amount of biogas. To simplify the process…
