The use of biomass fibers used as binders of a charcoal matrix --all done at ambient temperatures and at pressures generated by a simple hand press (12 to 15 bars) -and there are many such options– is certainly a viable alternative to boiling up starch or sugar on one end or purchasing the mechanized press and consuming the energy to generate the higher temperature/pressure for lignin melting. I will being the samples to the stoves camp to show what kind of densities can be achieved by infilling a properly processed fiber matrix with such as charcoal fines but I find it puzzling that this alternative now active in 67 nations globally, escapes mention.

Joshua B. Guinto in the Phillippines used the Oblak Holey Roket stove as inspiration and created a stove with an extra compartment to store char until cooking is done and the char is sufficiently cooled. He has done a wonderful job of writing up the results in the attached pdf.
From his conclusion:
The Charmaking Stove is Born!

  • The Char Making Holey Roket Stove is born!!
  • It allows harvesting bio char safely and conveniently and without having to tip the stove over. It eliminates the risk of heat fatigue, burns and open fires.
  • It allows clean cooking with the similar performance as a gasifier stove.
  • It allows continuous cooking.
  • The stove will last for four years or more.
  • It can be used with many other kinds of fuels.
  • The stove is much cheaper and can be fabricated in village workshops thus promotes social inclusion much better.
  • With clay, the stove has very small ecological footprint.

As the United States biomass thermal and power industry continues to expand, new reliable technologies offering higher efficiency solutions must be introduced. The newly introduced EOS series biomass gasification boiler is among the most energy efficient of AESI’s high-performance, low-maintenance biomass energy plants. The EOS series provides thermal outputs ranging from 600,000 BTU/hr to 20 million BTU/hr, and can be staged to provide increased capacity.

Designed and built by the leaders in the biomass waste to energy market in Europe, Uniconfort, the EOS series builds upon over 50 years of experience and over 4000 successful installations throughout the world. When asked about the highly efficient EOS series, CEO of Uniconfort Davis Zinetti notes, “we must not forget that greater efficiency is associated with less CO2 production. Choosing EOS, therefore, means making a choice in favor of the environment.”
