Abstract

A low-tech furnace for charring of raw bone using char coal is developed and tested. The furnace consists of a standard oil drum, fitted with simple materials as available in every market in small towns in developing counties. 80 kg of raw bone and 6 kg of charcoal are used for production of 50 kg of charred whole bones.

This yields about 30 kg of useful bone char grains. Special arrangement is developed in order to fire the produced evilsmelling gasses, without introducing oxic conditions in bone charring chamber. The furnace is scalable according to the capacity needed.
