Process

• Cascade Process
• Ethanol fermentation already existing in Brazil
• Biodiesel
• Hydrogen fermentation
• Methane fermentation

7
Installations involved

• A reactor of 1m3 capacity, fully equipped with
  the control units (heating/temperature control,
  pH-adjusting, substrate addition, sterilization,
  pressure control, among others)
• A laboratory to perform the analysis and control
  the parameters of the process.
• This laboratory shall get the data for the
  industrial scale fermentation, for the different
  raw materials available for this process.
• The local and ground facility will be offered by
  ERGOSTECH

Hydrogen Production Pathway

Microbial strain

• Patent microbe is owned by Sapporo Breweries
• Exploitation of the patent microbe subject to
  agreement of intellectual-property-rights
• Deposited microorganisms obtained from
  International Authority Depository (U.S.A. or
  Germany)
• Some deposited strains present hydrogen
  productivity near the Sapporo strain
• New strain screening might be another Joint
  Research Project
• Although this method requires time, we can obtain
  the new excellent microbes.

10
Expected Benefits

• Optimization of the renewable resources
  utilization
• Introduce an alternative product to be used as
  biofuel, using the same agricultural resources
• Increment in the energy recovery of approximate
  1.5 times (ca. 50 increase)
• Results in more energy and less waste release
• Alternative process to couple to other biofuel
  production process, including Biodiesel (oil
  production)

15m
Sapporo is designing the detail of each
equipments specification now. These layout,
therefore, is possible to be changed according to
their specs. If you have any opinions about this
plan, please inform us. Refer to your opinions,
Sapporo will modify this layout and specs.

Load Concentration

• Main components of the metabolite of hydrogen
  fermentation are organic acid
• About 10 of load decreases by hydrogen
  fermentation
• Organic acid is the most desirable substrate of
  methane fermentation
• Effluent is used effectively and can maximize the
  energy recovery from the biomass, if a rapid
  methane fermentation is coupled to use the
  organic acid (hydrogen fermentation effluent)

16
Fermentation Broth

• The load concentration before and after hydrogen
  fermentation (acid fermentation) is as follows
• At raw material concentration is 25 - 30 kg / m3
• COD of raw material broth is ca. 33,000 mg /
  liter
• COD of effluent is ca. 30,000 mg / liter
