After being dehydrated, suppressed and cooled, agricultural and forestry materials become the solid biomass fuels with great density and strength.

At the earlier stage of 1930s, Japan and German begin to explore the forming techniques.

In general, water content in harvested straws accounts for 46% higher.

When evaluating the biomass resources, we should not only care about their strengths, but should pay more attention to those potential strengths and remarkable shortcomings.

At present, the annual output of agricultural straws is about 602 billion tons according to the two parameters of wheat output and grain straw ratio.

The agricultural straw contains 1% higher potassium and other metals.

After so many years’ development, people still like to use the wood pellet mill for making the biomass fuels.

In general, smaller the size of raw materials, easier the work of wood pellet mill.

Until today, pelletizing technology of biomass fodders has entered into the perfecting schema.

Study on the molding technology of biomass particles starts from 1900s.
