Pellets and briquets from compacted biomass

A method of preparing a first compacted body comprising first particles comprising biomass, and second particles comprising a different material, wherein the compacted body containing the first particles and the second particles resists fragmentation, the method comprising:

• converting biomass feedstock to a form comprising said first particles;
• concurrently compacting the first particles and the second particles to produce the first compacted body having an energy content, wherein the compacted body has a total moisture content of about 15% by weight or less;
• and
• adjusting the compacted body composition based on seasonal fluctuations of the biomass feedstock;
• and
• compacting particles employing the adjusted composition to produce a second compacted body having an energy content consistent with that of the first compacted body produced,
• wherein the first compacted body has no more than about 300 ppm of chloride.
