Pretreatment and Thermochemical and Biological Processing of Biomass - Introduction to Chemicals from Biomass - page 83

biogas has already been used as vehicle fuel. Similarly, biogas is also injected into
the natural gas grid for public use in several European countries, for example
Germany and Switzerland [88]. In view of the advantages provided by AD, which
include organic waste valorization, the production of energy and soil conditioner,
and reduction of GHG emissions, AD is expected to become more common as a
biomass treatment.
3.5 Summary
With the global increase in energy demand and the depletion of fossil fuel sources,
it is necessary to search for alternative sources of chemicals and energy. Due to its
worldwide abundance, biomass represents an important source of renewable
chemicals and energy. Through various conversion methods, biomass can be used
to produce a wide range of biofuels, heat, electricity, and chemicals. In this
chapter, we have introduced the major thermochemical and biological conversion
processes available. The major products, process conditions, advantages, and
disadvantages of these conversion processes are summarized in Table 3.5.
