Briquetting of Biomass in Bangladesh ScienceDirect. Briquetting machines operating in Bangladesh are of heated-die screw-press type and mainly rice husk is used as raw material. The major problem identified for the machine development is the life of the screw. Usually, the screw tip wears out in a very short time (3-4 hours).

This primer discusses two approaches for estimating the biomass density of woody formations based on existing forest inventory data. The first approach is based on the use of existing measured volume estimates (VOB per ha) converted to biomass density (t/ha) using a variety of "tools" (Brown et al. 1989, Brown and Iverson 1992, Brown and Lugo 1992, Gillespie et al. 1992).
