PCIA Bulletin Issue 29
http://www.pciaonline.org/bulletin/pcia-bulletin-issue-29
This Bulletin focuses fuels for clean burning stoves. As they note, a lot of effort has been focused on wood burning stoves, but in urban areas, stick wood is hard to come by, and charcoal is a much more popular fuel. There's a good reason for this, studies have shown that charcoal stoves have up to 90% less indoor air pollution than similar wood stoves. In urban areas, there is a noticeable improvement in indoor air quality simply by shifting to charcoal burning. Additionally, biomass fuel briquettes, pellets, and other densified paper burning stoves are showing a lot of promise in urban areas so this bulletin profiles projects that use urban waste to create fuel briquettes that can be sold to stove owners.
