Construction of an incinerator for Biomedical Waste in Manhekarka, Nepal
About the Project
What's the problem?
Usually, infectious hospital waste in Nepal is burned in pits by pouring flammable liquids over it. The temperatures reached by this method are not high enough to sterilize the waste completely. In most cases, leftover waste will remain. This waste along with its germs and bacteria will be distributed around the hospital property from wind and animals. In the case of rain, the ground water may become contaminated as well. All of this increases the risk of infection for patients, hospital staff, visitors and neighbours. Technology without Borders faces this issue and provides a solution.
How to solve it?
Based on knowledge and social connections from a previous project in Nepal (Disposal of Biomedical Waste at the Outreach Clinic in Bolde, Nepal), this project is to counstruct an incinerator for burning biomedical waste in the township of Manhekarka. We will use the well-tried two chamber incinerator model of TeoG. Due to the two combustion chambers as well as the chimney with a height of 4 to 5m, constant temperatures of more than 800°C will be reached (peak temperatures up to 1050°C). As a result, the biomedical waste is sterilized, almost no carbon black and toxic gases arise (dioxin window between 300 and 600°C) and the waste volume is minimized. The ash can be burried without any concerns. The incinerators used in the previous project provided a burn rate of up to 20kg/h per incinerator.
The project will be implemented by Luca Frericks and Henning Risse and we keep you up to date on this site. Hope you enjoyed following along.
The last days have been very long and a lot has happened. From Tuesday to Thursday the construction went into the final phase and now we look a little bit proud of the finished work. The motivated welders arrived…
On Thursday after lunch the impossible became possible. A huge chimney pipe has found its way from Kathmandu to us. Motivated by the fact that only one part is missing, we fought our way through the seemingly never-ending construction…
Yesterday, everything happened in a flash. The last three layers of the inner wall of the incinerator needed only three and a half hours. Now, with German precision, the heart of the furnace is standing. And the bricklayers could…
