The briquetting is Richard's bag and I expect he will reply. To say that pellets "could be a bit expensive" is an understatement for those people that the Legacy Foundation teaches how to utilise crop residues as a cooking fuel. Essentially the process is a bit like making papiere mache from residues that has started to decompose, the fibres separate and then mesh together in a simple wet press. Other wastes like sawdust and charcoal fines can be entrained in the mesh of fibres to bulk the briquette and often in crease the energy content. They then dry in the sun. Yes they do burn TLUD http://stoves.bioenergylists.org/node/185 Have a search on Kobus Ventner and Rok Oblak at this site as they have a wealth of experience making briquette burning stoves.
