Project: "Development of non-waste technology for production
of bioethanol, biogas and bio-fertilizer from sweet sorghum
(Sorghum saccharatum Pers.)"
 Growing needs of the global and national economies in energy
necessitated development renewable energy and, in particular, bioenergy.
 Uzbekistan is one of the few energy-independent states of the world.
 To save fuel and energy independence should be involved in the energy
balance of the country alternative energy sources, such as bioethanol
and biogas
Biological features of sorghum (Sorghum saccharatum Pers).
In the soil and climatic conditions of Uzbekistan sweet sorghum grown in
the country, is the most economically profitable crop for production of
bioethanol.
In nature, there is no other technical culture
capable as quickly synthesize sucrose as
sweet sorghum.
Sorghum - a promising crop for the arid
steppe and semi-desert areas.
This is the most drought-resistant plant of
field crops, tolerates drought, loss of
moisture sparingly.
Advantages of sorghum sugar crops:
The highest yield of ethanol from the stem of the plant and its grain
at low cost.
High yield of biomass and grain (250t -30t / ha, respectively)
The high sugar content (15 - 40%)
The possibility of obtaining two full harvests per season at no
additional cost for planting (two mowings).
High drought - and salt tolerance.
Property to improve ameliorative condition of saline soils.
The ability to not seal the soil, as it is observed in growing sugar
beet.
In the Institute of Chemistry of Plant Substances, Academy of
Sciences of Uzbekistan explored biotechnological processing plant
sweet sorghum to obtain bioethanol, and its production of waste biogas and biofertilizer
Taking into account the specific characteristics of raw materials,
developed efficient, energy-saving methods for the preparation of
mixtures for the fermentation of the sorghum stems and sorghum
grain
Developed biotechnological method of disposing of waste
production of bioethanol - cake and a bard with the production of
biogas and bio-fertilizer
The purpose of the project:
Development of a new integrated waste technology processing of sweet
sorghum landraces that are of no nutritional value to obtain bioethanol,
biogas and bio-fertilizer.
Preparing a
mixture for
fermentation of
grain
Digestion
Distillation
Rectification
Preparing a
mixture for
fermentation of
stems
Waste:
Expeller
Bard
Recycling
Biogas
bio-fertilizer
Bioethanol
Objectives of the project:
The study of the sugar content in the stalks and grain sorghum landraces
and selection of the most sugary varieties.
Selection of effectiv, energy-efficient methods and optimal conditions for
the preparation of a mixture of fermentation separate the stems and grains.
Development of optimal conditions for fermentation, distillation and
rectification of bioethanol.
The study of the composition of the waste and the development of bioethanol
production biotechnological process recycling.
Installation of pilot plants for the production of bioethanol and recycling of
bioethanol production from biogas and bio-fertilizer.
Expected results and impact of the project:
Will have developed a new energy-saving biotechnology complex
processing of sweet sorghum, allowing to obtain bioethanol, biogas
and bio-fertilizer for agriculture
Design will be developed and installed two pilot-scale plant for the
production of bioethanol and disposal of its waste to produce biogas
and bio-fertilizer with high biological activity for the resumption of
fertility saline soils. Will be developed necessary regulatory and
technical documentation
The project will allow:
Get a cheap clean fuel,
Reduce the output of toxic gases from the burning of fossil
fuels,
Reduce the emission of toxic odors pharmaceutical production and improve working conditions for workers farmpred
enterprises,
Save natural gas for its own production of the Institute of
Chemistry of Plant Substances, Academy of Sciences of
Uzbekistan,
Improve ameliorative condition and fertility depleted the soil
of the republic.

Scientific and technical cooperation with foreign partners
- Possibility of foreign equipment for biotechnological production:
crushing device for crushing the stems of plants; mills for grinding
grain; apparatus for distillation and for rectification ; vacuum
pumps, compressors; and instruments for control and measuring;
- Supply of laboratory equipment for breeding pure cultures of
microorganisms and to control biotechnology logical process;
- Internship Uzbek specialists in foreign countries to get acquainted
with the latest achievements bioenergy
Traditional scientific directions of the Institute Plant Chemistry
of the Academy of Sciences of Uzbekistan are:
1 Chemistry of natural compounds - the selection, study of the structure
and chemical modification of a biologically active natural compounds, the
study of the relationship structure – activity
2 Pharmacology of Natural Compounds - screening and testing of new
materials for various kinds of biological activity; studying the mechanism
of action of natural and modified compounds, clinical study of the activity
of potential drugs
3 Agricultural chemicals - creating remedies Plant - growth promoters,
herbicides, fungicides and others
4 Technology herbal remedies - the development of new efficient
technologies, working hours substances of new medicines and plant
protection products on the pilot production of the Institute
