[Stoves] Coffee waste and briquettes

Wed Jan 3 02:50:23 CST 2018

Hi Paul,

Thanks for doing the research for me! 

On the stove – for Timor-Leste it would be easier to import gasifier units from Indonesia as there are a few successful examples there.

James,

I suggest that your consider pelletizing the coffee husks.   Results of a search:  (sorry for the format of the display.)   

And use pellets in the forced-air TLUDs like the FAABulous stove from South Africa.   You get the pellets and the stoves will do the rest.

Dear List,

Greetings from a rainy and power outage ridden Malawi. I’m after a quick
overview of using coffee waste to make briquettes if anyone has the
knowledge please. I’m just finishing up some work in Timor-Leste and there’s
a lot of coffee waste which could be put to good use. So what is a typical
mix of briquette feedstock if coffee husks are involved (approx. 7cm dia.
extruded) and what are the limitations of using this material? (The waste
stream is heavily seasonal and market dynamics lean towards an urban
briquette market. There is very little charcoal used)

The Legacy Foundation

Sell a series of manuals for  making their medium density holey
briquettes. Richard Stanley previously contributed a lot on [stoves]
about this but we have not heard from him recently.

The gist of the technique is that something "tachy" is initially
needed to hold the briquette together and in the mould before it is
dried when the compression allows hydrogen bonding to take over. The
process has similarities to paper making.

The  tackiness Richard mentioned is from allowing some biomass to
slightly rot (similar to retting in the preparation of linen fibres
from flax).

The briquettes are then air dried.
