• The project provides manufacture of the
  bio-diesel fuel received from algae oils.
  Productivity on the first year is from 4.000
  tons, with the subsequent increase within 5 years
  up to 50.000 tons one year. The most part of made
  bio-fuel will be realized on the territory of EU
  and in Republic Moldova. The investments involved
  in the project make 3 million Euro.
• With the increasing interest in bio-diesel as an
  alternative petro diesel, many have looked at the
  possibility of growing more oilseed crops as a
  solution for the problem of peak oil. There are
  two problems with this approach first, growing
  more oilseed crops would displace the food crops
  grown to feed mankind second, traditional
  oilseed crops are not the most productive or
  efficient source of vegetable oil. Micro-algae is
  the highest potential energy yield vegetable oil
  crop.
• In our project raw material for manufacture of
  oils will be micro-algae which are raised in
  bioreactors (installations of continuous
  all-the-year-round action).

• Micro-algae in 40-120 times with its potential
  power output surpasses rapeseed oil which is
  typical the representative of vegetative olive
  cultures.
• Micro-algae is an olive culture, capable to give
  the highest potential outputs of oil
• Liters of oil from hectare one year
• Grain 68,22
• Soybeans 181,92
• Sunflower 386,58
• Rapeseed 481,33
• Micro-algae 18950-56850
• Micro-algae grows within all year and has short
  life cycle
• Micro-algae the most fast-growing plant on
  Earth - grows in 100 times faster, than trees.
  Usually the weight of micro-algae for a day is
  doubled
• For micro-algae the readily available raw
  material is required sunlight, water, carbon
  dioxide and nutrients (? and N)
• From micro-algae it is possible to receive
  natural products pigments, fibers, enzymes,
  sugar, fats, amino acids, vitamins.
• Depending on kinds of algae (exists more
  than 30.000 kinds) and conditions of its
  cultivation, the chosen algae makes about 40-60
  of oil.
• Selection micro-algae grows in all
  environments. Even if the temperature of water
  makes - 2?.

• Bioreactors (installations for
  cultivation of algae ) provide fast growth of
  algae with the high contents of oil.

• The basic advantages of a bioreactor
• - Economy of space. The reactor can be
  established horizontally or vertically, both in a
  room, and behind its limits. There is no
  necessity for using big areas of the agricultural
  grounds. One bioreactor of 50 kg at one o'clock
  (430 tons of a biomass one year) with
  productivity of a biomass occupies the area 10 ?
  10 sq. meters.
• - The reactor considerably reduces
  expenditures of labor and eliminates complexities
  in service.
• - The system can work during long periods
  of time without destruction of culture.
• - Light in a reactor is taken as much as it
  considerably increases its productivity.
• - The bioreactor is equipped with convenient
  system of self-cleaning that reduces its
  pollution.
• - Reactors represent closed, controlled,
  automated systems of continuous action that
  allows to support hygiene of cultures in easier
  way. Ecological parameters of system also easily
  give in to management.
• - The size of a reactor is not limited.

Bio-diesel Fuel

• Bio-diesel fuel as the alternative of oil diesel
  fuel is the non-polluting kind of fuel received
  from vegetable oils, and used for replacement of
  usual diesel fuel. The bio-diesel engine differs
  good ?????????????????, that is provided with
  higher, than at "oil" ??????????, cetane number
  (56-58 against 50-52).
• From the chemical point of view the
  bio-diesel engine represents a methyl ether. By
  its manufacture, in process ????????????, oils
  and fats make a reaction with methyl spirit and
  sodium hydroxide, serving catalyst therefore fat
  acids are formed, and also by-products glycerin
  and others.
• The bio-diesel engine can be used in usual
  engines of internal combustion as it is
  independent, and in a mix with usual diesel fuel,
  without modification in a design of the engine.
• Possessing approximately identical energy
  potential with mineral diesel fuel, the
  bio-diesel engine has a number of essential
  advantages
• - It is not toxic, practically does not contain
  some sulfur and cancerogenic benzene
• - Decays in natural conditions (approximately the
  same as sugar)
• - Provides significant reduction in harmful
  emissions in an atmosphere at burning, both in
  engines of internal combustion, and in
  technological units
• - Increases cetane number of fuel and its
  greasing ability, that essentially increases a
  resource of the engine
• - Has high temperature of ignition (more than 100
  ?), that makes its use rather safe
• - Its source are renewed resources
• Cost of a bio-diesel engine now does not
  exceed cost of "oil" diesel fuel and tends to
  decrease, in relation to the last.
• The bio-diesel engine has received a wide
  circulation in many countries of the world. Among
  them, Germany, Austria, Czech, France, Italy,
  Sweden, the USA, and also other countries.
  Experts on motor technics count a bio-diesel
  engine the best fuel for motors with spontaneous
  ignition.
• The bio-diesel engine has big prospects in
  our country, on the one hand, it is considered as
  alternative renewed fuel, by way of maintenance
  of power safety of the state and execution of the
  law on renewed energy (? 160-XVI from
  12.07.2007), and on the other hand, in connection
  with euro-integration aspirations of Moldova and
  instructions of EU (since 2010 bio-fuel in the
  European Community should make not less than 5,75
  from all used fuel).
