Process to make it:
- THERMAL CONVERSION: processes in which heat is the dominant mechanism to convert
the biomass into another chemical form. The basic alternatives of combustion, torrefaction, pyrolisis, and gasification are separated principally by the extent to which the chemical reactions
involved are allowed to proceed.
- CHEMICAL CONVERSION: range of chemical processes may be used to convert biomass into
other forms, such as to produce a fuel that is more conveniently used,
transported or stored, or to exploit some property of the process
itself.
- BIOLOGICAL CONVERSION: many highly efficient biochemical processes have developed in nature
to break down the molecules of which biomass is composed, and many of
these biochemical conversion processes can be harnessed. Biochemical conversion makes use of the enzymes of bacteria and other
micro-organisms to break down biomass. In most cases micro-organisms
are used to perform the conversion process: anaerobic digestion, fermentation and composting.
Other chemical processes such as converting straight and waste
vegetable oils into biodiesel is transesterification. Another way of
breaking down biomass is by breaking down the carbohydrates and simple
sugars to make alcohol. However, this process has not been perfected
yet. Scientists are still researching the effects of converting biomass.
