Rattus carbonized

A rat experiment.

rat
184 gram rat

A dead rat in the garden, 184 gram, big enough to fill the little pyrolysiscell.

rat cell
Rat in the pyrolysis cell 3319 gram

A bit pushing was necessary to get the rat in the cell.

watervapor
Water vapor escapes

Brute force approach today heating up vaporizing the water content and pyrolysis phase direct afterwards.

hydro acro
Burning hydrogen and acrolein from the rat

Shortly flammable gases start to come out of the exhaust, mostly hydrogen gas and acrolein from decomposing fat.

rathead
carbon remains left the head is still recognizable

It is clear that animals remains don’t give nice pieces of biochar. The flesh melts when the cell membranes losing their integrity. On the left side is the skull of the rat with the front teeth is visible, the bones are very brittle. Only 24 gram remains 13% from the original 184 gram.

About Egidius Kuhlmann

Reading about peak-oil, overpopulation, “Terra Preta” and biochar in 2009 and after making batches biochar for soil improvement from garden residue, I thought, why not make biochar from corpses. Deeply worried about the unsustainable path 'we' as humanity have taken, I see a future where fossil fuels are scarce, the western economic growth model in tatters, the global temperature rises due to the CO2 concentration in the atmosphere with an growing population reaching billions more humans than is sustainable? Thinking along those paths, the question “how can we dispose so efficiently and with the least amount of energy of human remains” became the starting point.
